6 Technical description

The cooling units are suitable for use with 12 V or 24 V DC voltage and can therefore be used for camping or on boats. Furthermore, you can connect them to a 230 V mains supply via the rectifiers (see chapter “Accessories” on page 16).

When used on boats, the cooling unit can withstand a constant heeling of 30^ .

The cooling unit must be used together with an evaporator. In addition, you can use an accumulator with or without TEC control. The CS-NC15 comprises a cooling unit and an evaporator.

Use the continuously variable thermostat on the evaporator to set the desired temperature.

The accumulator and TEC program control ensure a high cooling capacity and improve the unit's efficiency. The accumulator is charged when there is a sufficient supply of power (for example when powered by a mains adapter). In the event of accumulator usage or under-voltage, the coolant is drawn from the accumulator until it is empty. Thus, no power is taken from the battery during this time.

The TEC program control always ensures that

• Cold energy is stored if there is excess electrical energy (external supply of power by a generator).
• The coolant accumulator can be used at any time to ensure that the complete battery power is used for other consumers.
• Stored cold energy is automatically retrieved to preserve the interior cooling temperature of the cooling area, once the battery capacity is exhausted.

NOTE

Further information on the coolant accumulator can be found in chapter "Use coolant accumulator" on page 27.

6.1 Battery monitor

The cooling device is equipped with an electronic device to protect against reversing the polarity when connecting to a battery. To protect the battery, the cooling device switches off automatically if the voltage is insufficient (see following table).

Devices without TEC control

Connection voltage Switch-off voltage Restart voltage
12 V	10.4 V 11.7 V
24 V	22.8 V 24.2 V

Devices with TEC control

24 V	22.0 V 26.0 V

7 Installing the cooling unit

WARNING!

The installation may only be performed by a qualified technician.

7.1 Tools required

For installation and assembly, you will need the following tools:

• D r i l l
• Screwdriver
• Open-ended spanner: 16 mm, 19 mm and 21 mm
• Sealant and PUR foam
• Cable, cable lugs and cable clips
• Esteroil

7.2 Notes on the cooling container

Permitted cooling area contents

Make sure that maximum cooling area contents specified are not exceeded for the respective evaporator type (see chapter "Technical data" on page 31).

Minimum insulation

The maximum cooling area contents are based on a minimum insulation thickness of 35 mm of foam polyurethane with a density of 40 kg/m^3 . If other insulating materials are used such as styrofoam, double the wall thickness to attain the same level of heat insulation.

Installing the evaporator

The evaporator must be installed in the cooling container (except CS-NC15, the evaporator is premounted).

Observe the following in the process:

• Correct installation position (fig. 3, page 4 up to fig. 9, page 6)
• Arrangement in the cooling container as far to the top as possible
  • Install a least 10 mm from the wall (not VD-14N and VD-15).

NOTICE!

For cooling units without valve couplings (ready-to install units): Do not open the refrigerant circuit during installation. You may have to make the wall openings larger to be able to slide the evaporator through them (fig. 11, page 6). Or alternatively, you create an opening that allows you to install the cooling lines at the top (fig. 12, page 6).

Connecting the evaporator

▶ Connect the evaporators VD-14N and VD-15 in accordance with fig. 10, page 6.
▶ Connect evaporator VD-16 according to fig. 9, page 6.
▶ Connect other evaporators according to fig. 19, page 9.

NOTICE!

Carefully insulate and seal off the wall openings after installation to prevent moisture penetration.

For cooling units with valve couplings

▶ Cut out a hole with a diameter of at least 30 mm (fig. 13, page 7) for the cooling lines. To do this, use a circular cutter.

NOTICE!

Never bend the connecting line between the evaporator and the unit. The minimum bending radius is 25 mm.

7.3 Installing the cooling unit

It is important to select the proper location for setting up the unit. To ensure trouble-free operation, please note the following points:

- Set up the cooling unit in a dry, sheltered place. Avoid placing it near heat sources such as radiators, gas ovens or hot water pipes. Do not place in direct sunlight.

- On a boat, install the cooling unit, if possible, below the waterline.

- The refrigeration unit functions at a tilt angle of up to 30^ . Install the unit on a flat base so that it will still operate, even at the strongest possible inclination.

• The heated air must dissipate unhindered (fig. 14, page 7).

- When installing the cooling unit in a closed room such as a wardrobe, pantry or aft compartment, openings must have a cross section of at least 200cm^2 (25cm×8cm) for cooling and exhaust air.

• Make sure that the air flow on the condenser (fig. 14 C, page 7) is not restricted.

- Maintain a minimum distance between the condenser and adjoining wall of 50 mm.

- CS-NC15: Observe the drilling template (fig. 21, page 11) and the installation drawing (fig. 22, page 12).

7.4 Installing the external temperature regulator

Mechanical thermostat

The temperature regulator can be mounted either on the outside or inside of the cooling container. The interior temperature is regulated depending on the surface temperature of the evaporator, or for VD-14N and VD-15, depending on the room temperature.

▶ Connect the coiled end of the sensor cable to the evaporator (fig. 15, page 8, not VD-14N, VD-15) using the clamping plate. This is premounted on VD-14N, VD-15.

▶ Make sure that the sensor line does not make contact anywhere else with the evaporator or with the suction line.

TEC control

The TEC control must be attached outside of the cooling container. The internal temperature is regulated according to the evaporator surface temperature.

The temperature sensor has been factory-mounted to the accumulator.

▶ Connect the temperature sensor with the TEC control via the plug-in coupling.

Mount the one-way couplings (not CS-NC15)

NOTICE!

Only persons who are skilled and knowledgeable in the field of refrigeration technology may connect one-way couplings. The general regulations for handling refrigerants must be observed!

The one-way couplings are only suitable for connecting the refrigeration units once. Re-opening or improper connection of the couplings will result in a complete loss of the refrigerant and in the failure of the refrigeration unit!

In such cases, the two previously connected parts of the cooling unit must be disassembled and send in. At the factory, the one-way couplings are renewed and the product is refilled with refrigerant.

The two components of the refrigeration unit – the evaporator and the compressor-condenser unit – are supplied separately. The components are connected with one-way couplings. The refrigerant quantity required to operate the entire refrigeration unit is already contained in the two components. A subsequent filling with refrigerant is, therefore, not necessary.

▶ Assemble the compressor-condenser unit and the evaporator unit.

Remove the protective caps and plugs from the unconnected halves of the one-way coupling of the compressor-condenser unit and the evaporator unit.

▶ Carefully clean the coupling seat and the threaded surface to prevent dirt or foreign material from entering the system.

NOTICE! Risk of coolant leakage

• Always use two wrenches when tightening the one-way couplings to prevent the pipes from twisting!

- Reusing the one-way couplings is not permitted!

- Determine which of the two one-way clutch connections is more difficult to access with the wrench and connect it first.

- Always connect only one one-way coupling connection and then the second.

NOTE

The O-ring is only an interim seal during the initial connection of the one-way couplings. This O-ring is only used for the initial sealing between the piercing of the diaphragm and the final metallic sealing. A leak-free seal is only achieved by a metallic connection between the two coupling halves.

▶ Apply refrigerant oil to the internal and external threads and to the internal mandrels (fig. 16, page 8).
▶ Connect the two halves of the coupling and screw them together by hand at first (fig. 17, page 8). Do not use a wrench!

One-way coupling with union nut:

▶ Screw on the coupling half with the union nut using a wrench size 21 mm and a wrench size 19 mm up to the end of the thread or until a noticeable resistance is felt. Do not tighten the screw connection yet.

The wrench size 19 mm serves as a guide when screwing on the union nut.

Connection of the one-way coupling with external thread:

▶ Screw on the coupling half with the union nut using a wrench size 21 mm and a wrench size 16 mm up to the end of the thread or until a noticeable resistance is felt. Do not tighten the screw connection yet.
The wrench size 16 mm is used for counterholding when screwing on the union nut.
▶ Use a pencil to draw a line lengthwise from the union nut to the bracket of the opposite coupling half.
Now tighten the union nut firmly with a torque of 30 Nm or another 1/4 turn. The offset of the line shows how strongly the one-way coupling was tightened.
This last turn is necessary to ensure a leak-free connection between the coupling halves.

NOTE

The distance between the beginning of the union nut and the hexagon of the external thread must not exceed 3 mm (fig. 17, page 8).

▶ Perform a leak test on the coupling connections. This ensures that the one-way couplings are correctly connected and the sealing is functional.

7.5 Connecting the cooling unit

Connecting to a battery

The cooling unit can be operated from a 12 V or a 24 V DC voltage supply.

NOTICE!

To avoid voltage loss and therefore a drop in performance, the cable should be kept as short as possible and should not be interrupted. For this reason avoid additional switches, plugs or power strips.

▶ Determine the required cross section of the cable in relation to the cable length according to fig. 18, page 8.

Key for fig. 18, page 8

Co-ordinate axis Meaning Unit

| Cable length m

∅Cable cross section mm²

NOTICE!

Make sure that the polarity is correct.

▶ Before you start up the unit for the first time, check that the operating voltage matches the battery voltage (see type plate).
- Connect your cooling unit - as directly as possible to the pole of the battery or - to a plug socket which is fuse protected with at least 15 A (at 12 V) or 7.5 A (at 24 V).

NOTICE!

Disconnect the cooling device and other power consuming devices from the battery before you connect the battery to a quick charging device. Overvoltage can damage the electronics of the device.

For safety reasons the cooling unit is equipped with an electronic system to prevent polarity reversal. This protects the cooling unit when it is connected to a battery.

Connecting to a 230 V mains supply

WARNING!

- Never handle plugs and switches with wet hands or if you are standing on a wet surface.

- If you are operating your cooling device on board a boat with a mains connection of 230 V from the land, you must install a residual current circuit breaker between the 230 V mains supply and the cooling device.

Seek advice from a trained technician.

▶ To operate the cooling unit from the 230 V mains, use the rectifier

• CoolPower EPS100 for devices with BD35F compressor (50/80/CS/CS series),
  – CoolPower MPS35 for devices with BD35F compressor (50/80/CS/CS series),
  – CoolPower MPS50 for devices with BD50F compressor (90 series).

NOTE

The output voltage of the described rectifier is 24 V. Please remember this when connecting other consumers at a later time.

8 Using the cooling unit

8.1 Energy saving tips

• Choose a well ventilated installation location which is protected from direct sunlight.
• Allow hot food to cool down first before placing it in the device.
• Do not open the refrigerated container more often than necessary.
• Do not leave the door open for longer than necessary.
• Defrost the refrigerated container once a layer of ice forms.
• Avoid unnecessary low temperatures.
• Clean the condenser of dust and dirt at regular intervals.
• Clean the lid seal regularly.

8.2 Start the cooling unit

Devices without TEC control

▶ Switch in the cooling unit by turning the control button clockwise (fig. 1 A1 or B1, page 3).

If you turn the control button further, you can regulate the temperature. Devices with energy storage function offer a storage activation button (fig. 1 A2, page 3).

NOTE

If the red LED flashed or glows, a fault has occurred and the system cannot be operated (see error table in Chapter chapter "LED on the thermal element (fig. 1 2, page 3)" on page 29).

Devices with TEC control

Devices with TEC control are started by actuating the main switch (fig. 2 6, page 3). You can then regulate the temperature (fig. 2 5, page 3) with the temperature selector.

8.3 Shutting down the cooling unit

If you do not intend to use the cooling device for a prolonged period, proceed as follows:

▶ Devices without TEC control: Turn the control to 0.
▶ Devices with TEC control: Switch off the device with the main switch (fig. 2 6, page 3).
▶ Disconnect the power cable from the battery or pull the DC cable plug out of the rectifier.
▶ Clean the cooling device.
Leave the door slightly open over the cover. This prevents odour build-up.

9 Use coolant accumulator

9.1 Display and control elements of devices with TEC program control

No. in

fig. 2,

page 3

Explanation

1 Green LED: Indicates that the compressor is working.

2 Yellow LED: indicates that the external power supply is present (voltage is higher than 13.5 V or 27.0 V).

The LED flashes if the external power supply is too low (voltage ≤ 10.7 V or 21.7 V. Version E: ≤ 10.7 V or 22.0 V).

3 Red LED: indicates that the accumulator is being discharged because

- the discharge button has been pressed

- Low voltage shutdown (voltage ≤ 10.7 V or 21.4 V. Version E: ≤ 10.7 V or 22.0 V).

4 Accumulator discharge button: interrupts compressor operation until

• the stored cold energy is exhausted

- The external supply voltage level is restored after low voltage.

5 Temperature selector: allows the temperature in the cooling area to be set as required

Min. (left limit) = warmest setting

Max. (right limit) = coldest setting

6 Main switch: for switching the cooling device on and off.

Position 0 = OFF

Position - = ON

9.2 Accumulator function

The accumulator function ensures that cold energy is stored automatically (up to 8 hours) if enough electrical power is available, for example when supplied by a mains adapter.

Stored cooling power is discharged

• automatically when the switch-off voltage is reached (see the table on page 18)
• or manually by pressing the discharge button (fig. 1 A2 or fig. 2 4, page 3).

NOTE

The cold accumulator can only be discharged manually if it was fully charged beforehand.

The accumulator is automatically charged if,

• the restart voltage is exceeded
- or the accumulator is empty and you switch the device off and on again using the control button(fig. 2 6, page 3, does only function on VD-06).

NOTICE!

When you are discharging the accumulator, although there is an external supply of power – for example to avoid operating noise from the compressor – use the main switch to switch the unit off (fig. 1 B1 or fig. 2 6, page 3).

NOTE

Please remember: Low internal temperature = high current consumption!
