3 Description of the unit

The LMS series includes air-cooled condensing units built on the basis of the single-block principle. They consist of:

1 3 A D 2

1. a condensing unit placed outside the cold room;
2. an evaporator installed inside the room;
3. an electric control panel placed on the condensing unit;

4 Operation

LMS single blocks are compression units where cold is produced by vaporizing a liquid refrigerant (HFC type) at low pressure in a heat exchanger (evaporator). The resulting vapour is brought again into the liquid state by mechanical compression at a higher pressure, followed by cooling in another heat exchanger (condenser).

The compressor is hermetic, with reciprocating motion, supplied with single-phase or three-phase power. Defrost takes place automatically in pre-set cycles, by means of heaters; manual defrost is also possible.

5 Handling

The unit can be handled by lifting and transport means.

UNSCREW THE FIXING SCREWS TO REMOVE CRATING FROM THE UNIT. (fig. A).

WARNING

Make sure that no one is in transit in the operating area of the lifting/transport means to prevent any possible accidents to people.

If the unit is in a wooden case or crate, sling the packing properly before handling it.

Lifting speed shall be such as not to make the packed unit oscillate dangerously and possibly fall.

6.3 Location

To obtain optimal operation of the unit act as follows:

A) Place the unit in a well ventilated room, far from heat sources.
B) Limit the number of door openings.
C) Make sure that the unit has good air supply and discharge.
D) Fit a drain line to the defrost water drain connection in the lower part of the unit.

Note: LMS units are equipped with automatic evaporation of defrost water; drain is just a precaution in case of troubles.

When installing the unit leave enough free room to allow opening, correct use and easy maintenance in safe conditions.

6.5 Installation

Straddle version:

Before mounting the unit prepare the cuts in the cold room wall as shown in the picture. Fix the unit in place with the appropriate screws. Position the unit on the cold room, connect the evaporator drain tray spigot and the hole prepared in the cold room wall using the supplied pipe with pre-inserted heater (for low temperature units only). Fill the hole in the wall with insulating material, polyurethane or silicone, and mount the hole cover.

9 Checks, regulations and adjustments

Before turning the unit on, check that:

• locking screws are tight
• electrical connections have been carried out correctly.

In the event that the unit has been opened:

• no tools were left inside
• assembly is correct
• there are no gas leaks
• front cover is secured correctly

9.1 Starting

Before starting the unit act as follows:

• Connect the unit to the mains. The luminous switch lights up
• If the unit has a preheating cycle, leave it in this condition for at least 3 hours.
• If the unit has a voltage monitor, leave it in this condition for at least 7 minutes to have the counting phase carried out
• Switch on the control by pressing key 0/1.
• Set the required cold room temperature.

ATTENTION

Medium temperature range: +5 -5°C

Low temperature range : -18 -25°C

ATTENTION

24 hours after starting check evaporator state. If ice has formed, defrost frequency should be increased. In low temperature units the evaporator condition should be checked every week during the first month of operation.

10. Wiring

A wiring diagram, specific for the units of the LMS series, is enclosed with these use and maintenance instructions.

11. Maintenance and repairs

Suitable maintenance is crucial for obtaining longer life, perfect working conditions and high efficiency of the unit as well as for ensuring the safety features provided by the manufacturer.

12 Routine maintenance

Good operation of the unit requires the condenser to be cleaned periodically (frequency of cleaning depends on the environment where the unit is installed).

Turn off the unit and clean it by blowing air from the inside outwards. Should no air jet be available, use a long-haired brush and work on the outside of the condenser.

In case of water-cooled condensers have the unit cleaned by a plumber with special descaling agents.

WARNING

Use safety gloves to protect your hands from possible cuts.

WARNING

Disconnect the unit before working on it.

12.1 Periodical maintenance

Periodically check wear condition of electrical contacts and remote switches; if necessary replace them.

12.2 Service operations to be carried out by qualified technicians or by the manufacturer

Following operations shall be carried out by qualified technicians or by the manufacturer exclusively. Under no circumstances the user is allowed to:

• replace electrical components
  • work on the electric equipment
  • repair mechanical parts
  • work on the refrigerating system
• work on the control panel, ON/OFF and emergency switches
  • work on protection and safety devices.

12.3 Troubleshooting

During operation following troubles may occur:

1 Compressor stops. The unit is equipped with an overtemperature device which stops the compressor every time the max. allowable temperature of motor windings is exceeded. Possible causes are:

• insufficient ventilation of the room where the unit is installed;
• anomaly in mains voltage;
• faulty operation of condenser fan.
  Device reset is automatic.

2 Ice forms on the evaporator preventing air from flowing regularly.

Possible causes are:

• the door is opened too frequently;
• faulty operation of evaporator fan;
• faulty solenoid valve (in models with hot gas defrost);
• faulty defrost heater (in models with electric defrost);
• faulty defrost process. In this case some measures can be taken:

increase defrost termination temperature by some degrees, increase number of defrosts.

ATTENTION

Do not use either hot water or any pointed, cutting, metal objects to remove ice blocks.

3. Display does not light up. Check:

• if there is power to the unit;
• if mains cable is connected properly;
• fuses inside the electric panel

Unsatisfactory efficiency of the unit:

If no defects are found in the unit check that: cold room doors are perfectly tight dispersion; the cold room is used wisely; no unfrozen liquids or foodstuffs are placed in the low temperature room; the evaporator is ice-free.

We recommend installation of the machines far from the doors especially when the cold room is expected to be opened many times a day.

WARNING:

Removal of protections during machine operation is absolutely forbidden. They have been developed to safeguard the operator's safety.
