In case there is ice formation on the unit, do not use hot water or any mechanical tools or objects to remove the ice. This could cause damage and a potential leak.

Disclaimer

Should you come into possession, legitimate or not, of the OEM password of the installation, you are prohibited from changing any parameters via that privileged access level. Daikin always reserves the possibility of performing an integrity check of the factory parameters. If these are found to have been tampered with, Daikin is in no way liable for any resulting failure, damage or warranty obligation.

Refrigerant

The unit is factory charged with refrigerant, no additional charging of refrigerant is required.

DANGER

This unit uses R290 as refrigerant. Do NOT discharge refrigerant in the atmosphere, it must be recovered by specialised technicians using suitable equipment.

DANGER

Take sufficient precautions in case of refrigerant leakage. If refrigerant gas leaks, immediately switch off the power supply (for each unit) and ventilate the area. Possible risks:

• Carbon dioxide poisoning.
• Asphyxiation.
  Fire.

WARNING

• NEVER directly touch any accidental leaking refrigerant. This could result in severe wounds caused by frostbite.

• Do NOT touch the refrigerant pipes during and immediately after operation as the refrigerant pipes may be hot or cold, depending on the condition of the refrigerant flowing through the refrigerant piping, compressor, and other refrigerant cycle parts. Your hands may suffer burns or frostbite if you touch the refrigerant pipes. To avoid injury, give the pipes time to return to normal temperature or, if you must touch them, be sure to wear proper gloves.

WARNING

• Do NOT pierce or burn refrigerant cycle parts.
• Do NOT use cleaning materials or means to accelerate the defrosting process other than those recommended by the manufacturer.
• Be aware that the refrigerant inside the system is odourless.

INFORMATION

R290 is denser than air, so in open air it sinks to floor level.

Electrical

DANGER: RISK OF ELECTROCUTION

• Turn OFF all power supply before removing the switch box cover, connecting electrical wiring or touching electrical parts.
• Disconnect the power supply for more than 10 minutes, and measure the voltage at the power supply terminals of the compressor inverter before servicing. The voltage MUST be less than 50VDC before you can touch electrical components.
• Do NOT touch electrical components with wet hands.
• Do NOT leave the unit unattended when the service cover is removed.

WARNING

NEVER replace a fuse with a fuse of a wrong ampere rating or other wires when a fuse blows out. Use of wire or copper wire may cause the unit to break down or cause a fire.

WARNING

After finishing the electrical work, confirm that each electrical component and terminal inside the electrical components box is connected securely.
- Make sure all covers are closed before starting up the unit.

WARNING

NEVER touch the person receiving an electrical shock, or you could suffer one too. Do NOT touch the person until you are sure power is turned off. Electrical shocks always need emergency medical attention, even if the person seems to be fine.

WARNING

A magneto thermal circuit breaker, having a contact separation in all poles providing full disconnection under overvoltage category III condition, MUST be installed in the fixed wiring. In case of multiple units each unit must have its own circuit breaker.

Note that this magneto thermal circuit breaker should not be used to turn the unit on and off under normal operating conditions. For that, one should use the controller.

WARNING

A Residual Current Device (RCD) MUST be installed in the fixed wiring. In case of multiple units each unit must have its own circuit breaker.

This to initiate automatic disconnection of the power supply upon detection of an insulation fault from a live part to exposed conductive parts or to earth.

Device specifications must be determined by a qualified installer, based on the applicable national standard.

About the unit and options

CAUTION

This equipment is NOT intended for use in residential locations and will NOT guarantee to provide adequate protection to radio reception in such locations.

About the system

The LMCEY unit is a refrigeration indoor unit which allows to refrigerate air through vaporising a liquid refrigerant (Hydrocarbon R290 type) at low pressure in a heat exchanger (evaporator). The resulting vapour is brought back to liquid state by mechanical compression at a higher pressure, followed by cooling in another heat exchanger (condenser).

Depending on the model, LMCEY units can be air cooled (LMCEY1A13AVM01 + LMCEY2A19+25AYE01) or water cooled (LMCEY1W12AVM01 + LMCEY2W19+25AYE01).

Defrosting takes place automatically by injecting hot gas; manual defrosting is also possible.

INFORMATION

The A-weighted sound pressure level of the unit is less than 70 dBA.

The measurement complies with UNI EN ISO 3746:2010.

The menu where the parameter is situated is indicated in this column.
A modification of the parameters other than those shown in the table may affect the proper operation of the unit. ONLY have them changed by a professional.
Parameters AH and AL are used to set the thresholds relative to the set point for the high and low temperature alarms.
To protect the refrigerated products, management of these two alarm thresholds will override normal control:
AL (low temperature alarm threshold): when the coldroom temperature is lower than the threshold AL, the compressor is immediately stopped.
- AH (high temperature alarm threshold): when the coldroom temperature is higher than the threshold AH, the compressor works at maximum speed.
The unit is equipped with the possibility to enable the Eco mode, to save energy at certain times (e.g. at night).
The function can be activated by the user and must be evaluated in alignment with HACCP procedures.
To reduce energy consumption, during Eco operation, the set point of the unit is increased by the value as set in parameter r4.
Eco operation can be activated on the user interface or by using the Daikin app, by pushing the Eco icon in the home page or by changing the time bands, with the same priority.

4.4 To set the shared functions for multiple units

NOTICE

Make sure the software version of all units is the same and up-to-date. If it is not the latest version, update the software, otherwise the units may not work properly due to suboptimal communication.

INFORMATION

In case the secondary unit controller is offline, the primary unit controller will keep all functions working, without taking care of the specific secondary unit controller that is no longer available (network regulation, network defrost, door,...).

From the secondary unit controller side, the controller will try to guarantee the cooling, so it will regulate on the cold room temperature.

Lights

Lights can be connected to all controllers in the network and the light status is always synchronised. Each controller will turn the lights on and off simultaneously.

Door open

The door microswitch must be connected to the primary unit controller in the network.

As for the lights, also the door status is shared to all controllers. Every controller knows if the door(s) is/are open or not, and each controller can perform actions.

Network temperature regulation

INFORMATION

To change parameters related to this functionality, "Service" level access is required.

The temperature regulation can be performed in two ways depending on the parameter "nrt" with the following values:

• 0: The relative controller regulates through the probe connected to itself.
• 1: The relative controller regulates through the probe connected to the primary unit controller.

The network logic allows avoiding simultaneous starts of compressors. Using the "SSd" parameter it is possible to set a delay between starts of different LMCEY units.

If it is necessary to start several units at the same time, the first unit to signal to start will be the first one to start. After "SSd" the next unit will also start and so on (See the example below).

1 On
0 Off
A Compressor status
B Request status
C1 Compressor secondary unit 1
C2 Compressor secondary unit 2
C3 Compressor secondary unit 3
C4 Compressor secondary unit 4
CM Compressor primary unit
SSd Delay between start up [s]

Note: LMCEY2A/W units have two compressors, but work in a similar way. The two compressors of the same unit work synchronously.

Network defrost

INFORMATION

To change parameters related to this functionality, "Service" level access is required.

It is possible to enable/disable this functionality for each controller separately.

Defrost can be synchronised between the primary unit controller and secondary unit controllers using parameters dS_1, dS_2, dS_3, and dS_4 with the following values:

• 0: No synchronisation performed.

1:Only starting.

Only starting: secondary unit controllers will start to defrost at the same time as the primary unit controller, and all controllers can finish in different moments.

• 2: Start & Stop.

Start & Stop: secondary unit controllers will start to defrost at the same time as the primary unit controller. If one controller ends defrosting before the others, the corresponding defrost relay is de-energised and the dripping phase will only start when all other controllers have finished the defrosting phase.

ds_1=0
ds2=1
ds-3=2
ds_4=2
d2 = 0

ds_1 = 0
ds2=1
ds-3=2

Local defrosting on a LMCEY unit is still possible in two ways:

• Manually (from app, supervisory system or user interface).
• If not manually started, each unit will perform a defrost every 4 hours to allow the correct operation of the unit.

When a malfunction is detected:

• The error code is shown on the display, alternating with the main value. This allows immediate identification of the malfunction.
• The "service" icon is shown on the display.

a "Service" icon
b Main value
c Error code

There are 2 types of malfunctions:

• Warning

The buzzer does not sound.
- No relay is activated.

Errors belonging to this category include defrost ended after maximum time, dirty condenser, HACCP alarms and configuration errors.

• Alarm

The buzzer sounds.
The concerning relay is activated.

This category includes alarms for which the relay is configured as an alarm, probe errors, temperature alarms, etc.

INFORMATION

If there is an active alarm the buzzer will sound. Press any button to mute the buzzer.

Take into account that:

Alarms and warnings are identified by error codes. For the error code table, see "8 Troubleshooting" [▶ 20].

If more than one warning/alarm occurs, they are displayed in sequence.

The warning and alarm signals can be immediate or delayed by parameter.

4.5.3 To reset an alarm or warning

Both warnings and alarms can be reset automatically, manually, or semi-automatically (see "8.1 Error codes: Overview" [▶ 22]):

Automatic: when the cause is no longer present, the alarm also ceases.
- Manual: when the cause is no longer present, the alarm remains active until manually reset by parameter.

The alarms can be reset manually by setting parameter rSA to "1", via the user terminal or in the Daikin app (Bluetooth connection only), using the specific command on the alarms page.

If the condition that generated the alarm is still present, the alarm is reactivated after resetting.

4.5.4 About the alarm log

Alarm log

When an alarm is cleared, it is stored in the alarm log containing a maximum of 5 alarms, in a FIFO list (the 6th alarm overwrites the first alarm, and so on). The error log is accessible via the user terminal, via supervisor or the Daikin apps (Bluetooth connection only).

The controller can record both periodic and event logs, which can then be viewed and downloaded using the Daikin apps.

1 To view the periodic logs in Daikin User: Select Trend in the hamburger menu (tab) Logs.
2 To view the event logs in Daikin User: Select Trend in the hamburger menu (tab) Events.

a Preset

b Periodically logged variables c Legend

The log view is pre-set, however it CAN be changed using the legend choice. In addition, the pre-set views loaded on the device allow the main values to be filtered (temperature, HACCP alarms, blackouts, etc.). To download the logs, use the drop-down menu at the top right.

The periodic logs record the main values at regular intervals, as shown in the table below.

Evaporator fan, minutes ON in the period	min 1 h

Event logs are recorded when specific conditions occur, and can be used to store certain related values, as shown in the table below.

The type of alarm recorded in the log can be identified using the alarm information (see "8.1 Error codes: Overview" [▶ 22]).

Logged value	Event Other recorded values		Sample s*	Limit s
Alarm	Alarm activation	Number of the active alarm with highest priority. Alarm status (active/ceased)	20 max	255 alarm
Blackout	Device ON Power failure duration in minutes		20	1000 hours
HACCP alarms	HA or HF alarm	Type HA or HF alarm	10	-

• The samples are stored in a circular FIFO list (e.g. for the alarms, the 21st alarm overwrites the first alarm, and so on).

NOTICE

Changing the time set on the controller by more than 140 minutes will clear the stored logs.

The alarm log can be deleted using the Daikin Apps (Bluetooth connection only) using the specific command on the alarms page.

INFORMATION

Deleting the alarm log is irreversible.

5.2 Operation procedure

• Read the documentation carefully before operating the unit to ensure the best possible performance.
• Turn ON the unit before storing the refrigerated goods. Varies from 15 to 30 minutes, depending on the ambient temperature.
• Choose the correct temperature setting for the product that is to be stored (see "4 User interface" [▶ 9]).
• A door micro switch interrupts the unit operation and turns on and off the cold room lamp when the cold room door is opened. The cold room lamp can also be switched on and off via the user interface or via the Daikin apps.
• Bluetooth makes it possible to check and control the unit via the Daikin User app.
• Multiple units (up to 5) can be combined within one cold room. They will then operate according to the primary/secondary principle.

Advantages:

Higher cooling capacity.
Redundancy should a unit break down.
- Better airflow.

5.3 Storing the goods

NOTICE

Do not cover the air intake and outlet openings towards the condenser and evaporator of the unit.

Maintaining the right temperature guarantees the preservation of the quality of the stored goods.

Air circulation is of absolute importance to keep a uniform temperature throughout the entire cold room. Insufficient air circulation can cause heat pockets or ice formation.

For this reason:

• Use pallets or racks that facilitate air circulation under the goods.
• Place the goods away from the cold room walls. Use spacers if necessary.
• Leave a space of approximately 20cm between the goods and the cold room ceiling.
• Stack heat generating products, such as fruit and vegetables, in a way to create sufficient space to remove the generated heat by cold air circulation.
• Stack products which do not generate heat, such as meat and frozen foods, close to each other toward the center of the cold room.

WARNING

Daikin is not responsible for cold room safety.

Make sure that no people are left in the cold room before you close the doors:

• Risk of suffocation. 12 ~m^3 must be left empty inside the cold room.
• Risk of frostbite.
• Risk of freezing to death.

5.4 HACCP alarms

This unit is provided with the HACCP control function. The HACCP (Hazard Analysis and Critical Control Point) is a management system designed to identify health hazards and to establish strategies to prevent, eliminate, or reduce their occurrence.

The HACCP control function embedded into this unit allows control and monitoring of the critical control point (refrigeration temperature).

It is also possible to download reports demonstrating compliance with current law.

By using the Daikin app, it is possible to enable the HACCP data recording on the unit by changing the parameter "Htd". See "4.3 Configuration" [▶ 11].

The initial setting of the "Htd" parameter is "0", meaning that HACCP data recording is disabled.

Specific alarms

There are specific alarms for controlling the operating temperature, recording any anomalies due to power failures or an increase in the temperature due to other causes (breakages, extreme operating conditions, user errors, etc.).

Two types of potentially critical HACCP events are managed:

• Type "HA" alarms, high temperature during operation:

The type "HA" alarm is generated if during normal operation the temperature read by the control probe exceeds the high temperature threshold for 60 minutes (delay time for high and low temperature alarms) + "Htd" (HACCP alarm delay). Consequently, compared to the normal high temperature alarm already signalled by the controller, the type "HA" HACCP alarm is delayed by a further time "Htd" specifically for HACCP recording.

Example: The critical temperature was exceeded, the alarm was not managed and the temperature remained above the threshold for longer than the maximum tolerable time (thresholds defined by site HACCP procedures).

Par.	Description Def.	Min. Max. UOM Menu App
Htd	HACCP alarm delay	0 (monitoring disabled)	0 240 Min	●
HAn	Number of type HA alarms	0 0 15	-	●		HcP	●
HA1 , HA2 , HA3	Activation date and time of the first, second and third type HA alarm	...	...	...	-		●

• Type "HF" alarms, high temperature after power failure:

The type "HF" HACCP alarm is generated following a power failure, if when power returns the temperature read by the control probe exceeds the "AH" high temperature threshold. "HFn" indicates the number of type "HF" alarms activated.

Example: The unit was powered off. When restarted, the temperature is above the threshold and does not return to an acceptable level within an appropriate time (parameters defined by site HACCP procedures).

Par.	Description	Def.	Min.	Max.	UOM	Menu	App
HFn	Number of type HF alarms	0	0 15	-	-	HcP	-
HF1, HF2, HF3	Activation date and time of the first, second and third type HF alarm	...	...	...	-		-

When an alarm occurs, the HACCP icon comes on, the display shows the alarm code, the alarm is logged and the alarm relay and buzzer are activated.

The "HA" and "HF" alarms can be reset using the Daikin app. See "4.5.3 To reset an alarm or warning" [▶ 16].

The HACCP event log can be deleted by using the Daikin app, via the drop-down menu on the side, selecting "Alarms -> Alarm history -> Clear logs".

NOTICE

Deleting the HACCP event log is irreversible.

6 Energy saving and optimum operation

If circumstances allow:

• Do not place unfrozen liquids or foodstuffs in the cold room (when used as freezer).
• Reduce the opening frequency of the cold room doors.

Always:

• Reduce the opening time of the cold room doors.
• Make sure that cold room doors are perfectly tight.
• Make sure that a good airflow is possible between the stored goods.
• Check that the evaporator is ice-free. Ice forms on the evaporator preventing air from flowing regularly.

7 Maintenance and service

INFORMATION

Suitable maintenance is crucial for obtaining longer life, perfect working conditions and high efficiency of the unit. It also ensures the proper functioning of the safety devices provided by the manufacturer.

7.1 Cleaning the unit

7.1.2 To clean the interior

NOTICE

To clean the unit enclosure:

• Do not use any cleaning agents or chemicals.

DANGER: RISK OF ELECTROCUTION

• Turn OFF all power supply before removing the switch box cover, connecting electrical wiring or touching electrical parts.
• Disconnect the power supply for more than 10 minutes, and measure the voltage at the terminals of main circuit capacitors or electrical components before servicing. The voltage MUST be less than 50 V DC before you can touch electrical components. For the location of the terminals, see the wiring diagram.
• Do NOT touch electrical components with wet hands.
• Do NOT leave the unit unattended when the service cover is removed.

CAUTION

Do NOT touch the heat exchanger fins. These fins are sharp and could result in cutting injuries. Wear safety gloves if you have to work on or around the heat exchanger fins.

WARNING

Do NOT use water for cleaning. Use of water can damage electrical components.

Good operation of the unit requires the condenser and evaporator to be clean. The frequency of cleaning depends on the environment where the unit is installed.

INFORMATION

Under normal working conditions the condenser and evaporator should only be cleaned during scheduled maintenance inspections.

Condenser heat exchanger cleaning

1 Turn off the unit.
2 Clean the condenser heat exchanger with a long-haired brush or by blowing (low pressure) air from the inside outwards.

NOTICE

Do not use high-pressure air to clean the condenser heat exchanger fins. It will damage them and prevent proper operation of the condenser heat exchanger.

WARNING

Do NOT use water for cleaning. Use of water can damage electrical components.

Should the fins nevertheless get bent:

3 Straighten them carefully using a fin comb for cleaning/ straightening.

Evaporator heat exchanger cleaning

1 Set the unit at minimum operating temperature and wait for ice build-up.
2 Activate the unit manual Defrost mode.
3 Check if the evaporator heat exchanger is clean.
4 Turn off the unit.
5 Clean the evaporator heat exchanger with a long-haired brush or by blowing (low pressure) air from the inside outwards or with (low pressure) water spray.

NOTICE

Do not use high-pressure water or air to clean the evaporator heat exchanger fins. It will damage them and prevent proper operation of the evaporator heat exchanger.

INFORMATION

It is allowed to use water spray for cleaning the evaporator heat exchanger. Water will go through the drain pipe. Make sure the drain pipes are NOT clogged with dirt coming out of the evaporator heat exchanger.

7.1.3 To clean the water circuit

In some applications, such as when using very hard water at high temperatures, it may be necessary to clean the water circuit to ensure the best operation of the plate heat exchanger.

Clean at regular intervals.

Clean the water circuit by putting a cleaning fluid into circulation.

1 Use a tank with a weak acid, e.g. 5% phosphoric acid or, if the circuit is cleaned frequently, 5% oxalic acid.
2 Pump the cleaning liquid into the water circuit through the (lower) water inlet connection (a) for the purpose of ventilating the air. For optimum cleaning, the flow rate should be at least 1.5 times the normal rate, preferably in reverse mode.

3 Reverse the flow direction every 30 minutes, if possible.
4 Replace the cleaning acid with a 1 - 2% solution of sodium hydroxide (NaOH) or sodium bicarbonate (NaHCO3) for the last rinse, to ensure that all acid has been neutralized.
5 After cleaning, rinse the heat exchanger thoroughly using clean water.

8 Troubleshooting

If one of the following malfunctions occurs, take the measures shown below and contact your dealer.

WARNING

Stop operation and shut OFF the power if anything unusual occurs (burning smells etc.).

Leaving the unit running under such circumstances may cause breakage, electrical shock or fire. Contact your dealer.

WARNING

If the internal wiring or the supply cable is damaged, it has to be replaced by the manufacturer, its service agent or similarly qualified persons.

The system MUST be repaired by a qualified service person.

Malfunction	Measure
If a safety device such as a fuse, a breaker or an earth leakage breaker frequently actuates.	Turn OFF the main power switch. Notify your installer and report the malfunction.
If water leaks from the condenser side of the unit.	Stop the operation. • Check that the drain pan pipe has no leaks. • Check that the external drain pan pipe is properly connected. • Check that all the thermal insulation sponges provided with the unit are properly installed. • Check that there are no leaks in the water circuit (only for LMCEY1W+LMCEY2W). • Check that the connections of the water inlet and outlet pipes have been made properly. (only for LMCEY1W+LMCEY2W)
If water leaks from the drain pan under the evaporator.	Check that the drain pan pipe is not clogged.
The operation switch does NOT work well.	Turn OFF the power supply.
If the user interface display indicates an alarm.	Check section "8.1 Error codes: Overview" [22]. Notify your installer and report the error code.

If the system does NOT operate properly except for the above mentioned cases and none of the above mentioned malfunctions is evident, investigate the system in accordance with the following procedures.

Malfunction

Measure

If the system does not operate at all.

·Check if there is no power failure. Wait until power is restored. If power failure occurs during operation, the system automatically restarts immediately after power is restored. ·Check if no fuse has blown or breaker is activated. Change the fuse or reset the breaker if necessary. ·Check if the mains cable is still connected properly. ·Check if the user interface in the remote control panel is still connected properly.

Malfunction	Measure
Unit does not start operating when pressing ON/OFF key, the display however is turned on. Notice that the compressor starts up after a pre-set delay. This function is useful to protect the compressor and the relay from power cycling in the event of repeating power outages. Defrosting (if required) also starts after this delay.	·Check the door micro switch. The switch must be actuated and the NO contact must be closed when the door is closed.
Compressor stops. The unit is equipped with an overtemperature device which stops the compressor every time the max. allowable temperature of the inverter circuit board is exceeded. Possible causes are: ·Insufficient ventilation of the room where the unit is installed. ·Unit working outside the operating range. ·Anomaly in mains voltage. ·Faulty operation of condenser fan (or inverter cooling fan). Device reset is automatic after temperature dropped to normal.	·Make sure to have installed all the metalsheet panels of the unit and check if air inlet or outlet of the un condenser is not blocked by obstacles. Remove any obstacles and make sure the air can flow freely. ·Make sure to operate in the unit operation range (see "5.1 Operation range" [17]). ·Make sure that the unit has been installed properly. Refer to "General installation guidelines" in the installation manual. ·Check power supply (voltage). Correct if necessary. ·Check operation of the condenser fan (or inverter cooling fan).
