FIG-0

Check before starting up the device that all parts are available belonging to the scope of delivery.

Intended use

The cooling box is suitable for cooling and heating of foodstuff. The cooling box is designed to be operated from a DC power supply socket of a vehicle or from an AC power supply. The cooling box is also suitable for camping use. The cooling box is intended to be used in household and similar applications such as

staff kitchen areas in shops, offices and other working environments
farm houses
clients in hotels, motels and other residential type environments
bed and breakfast type environments
catering and similar non-retail applications

The cooling box is not suitable for:

storage of corrosive, caustic or solvent-containing substances
deep-freezing of foodstuff

This cooling box is not intended to be used as a built-in appliance. This product is only suitable for the intended purpose and application in accordance with these instructions. This manual provides information that is necessary for proper installation and/or operation of the product. Poor installation and/or improper operating or maintenance will result in unsatisfactory performance and a possible failure. The manufacturer accepts no liability for any injury or damage to the product resulting from:

Incorrect assembly or connection, including excess voltage
Incorrect maintenance or use of spare parts other than original spare parts provided by the manufacturer
Alterations to the product without express permission from the manufacturer
Use for purposes other than those described in this manual

Dometic reserves the right to change product appearance and product specifications.

Technical description
The cooling box is a low-wear thermoelectric cooler with fan-assisted heat removal. The cooling box can cool goods up to max. 27 °C (TCX07: 25 °C) under ambient temperature (thermostatic switch-off at approx. 2 °C) or keep them warm up to max. 65 °C. If the cooling box has reached the set temperature range, it will automatically switch over to the energy saving mode. In this mode only the energy which is required to reach the temperature inside the box is consumed. The cooling box is equipped with an automatic priority circuit. Thus it is ensured that with simultaneous connection to the AC mains supply and to a 12/24 V battery, the AC mains supply will be used.

Operation

NOTICE! Damage hazard
Only store objects or goods in the cooling box which may be cooled or heated to the selected temperature.

To avoid food waste, note the following:

Keep temperature fluctuation as low as possible. Only open the cooling device as often and for as long as necessary. Store the foodstuff in such a way that the air can still circulate well.
Adjust the temperature to the quantity and type of the foodstuff.
Foodstuff can easily absorb or release odor or taste. Always store foodstuff covered or in closed containers/bottles.

Before first use

Clean the cooling box inside and outside for hygienic reasons (see chapter “Cleaning and maintenance”

Saving energy

Choose a well ventilated location which is protected from direct sunlight.
If you want to set an increased energy efficiency and a limited cooling capacity for the cooling device, use the device’s ECO mode (TCX14, TCX21, TCX35).
Allow warm food to cool down first before placing it in the cooling device to keep cool.
Do not open the cooling device more often than necessary.
Do not leave the cooling device open for longer than necessary.
On a regular basis, make sure the lid seal still fits properly.

Connecting to vehicle power

NOTE
If you connect the cooling device to the vehicle power, remember that you may have to turn on the ignition to supply it with power. For safety reasons the cooling box is equipped with an electronic system to prevent
polarity reversal. This protects the cooling box against short-circuiting when connecting to a battery.

Opening the cooling box

TCX35 only: Unlock the cooling box (fig.2, page 3).
Open the cooling box.

Connecting the cooling box to 230 Vw TCX07

Connect the AC cable to the power adapter.
Plug the other end of the AC cable into the socket (AC main side).
Connect one end of the DC cable to the power adapter.
Connect the other end of the DC cable to the DC socket at the cooling box.

TCX14, TCX21, TCX35

Connect the cooling box using the AC connection cable supplied (fig.11, to an AC mains power socket.

Connecting the cooling box to 12 Vg

NOTE
The plug’s polarity cannot be reversed: it can only be inserted into the socket in one direction.

TCX07
1. Plug one end of the 12 V connection cable into the socket of the cooling box.
2. Connect the other end of the 12 V connection cable to the DC socket in your vehicle (fig.5, ) DOMETIC TCX07 Thermoelectric Cooler
FIG-5

TCX14, TCX21, TCX35

Connect the cooling box using the DC connection cable supplied (fig.12,) to the DC socket in the vehicle (fig.5, )

Using the battery monitor (TCX14, TCX21, TCX35)
The cooling device is equipped with a two-level battery monitor that protects your vehicle battery against excessive discharging when the cooling device is connected to the DC power supply (fig.13,) If the cooling box is operated when the vehicle ignition is switched off, the cooling box switches off automatically as soon as the supply voltage falls below a set level. The cooling box will switch back on once the vehicle battery has been recharged to the restart voltage level.

NOTICE! Damage hazard
When switched off by the battery monitor, the vehicle battery will no longer be fully charged. Avoid starting repeatedly or operating current consumers without longer charging phases. Ensure that the vehicle battery is recharged.

In “HIGH” mode, the battery monitor responds faster than at the level “LOW” (see the following table).

Battery monitor mode	LOW	HIGH
Switch-off voltage at 12 V	10.1 V	11.8 V
Restart voltage at 12 V	11.1 V	12.6 V
Switch-off voltage at 24 V	21.5 V	24.6 V
Restart voltage at 24 V	23.0 V	26.2 V

Proceed as follows to select the battery monitor mode:

Switch on the cooling box (see chapter “Switching on the cooling box”
To select the battery monitor mode, push the switch into the “HIGH” position or the “LOW” position.
To switch off the battery monitor mode, push the switch into the “OFF” position.

NOTE
When the cooling device is supplied by the vehicle battery, select the battery monitor mode “HIGH”. If the cooling device is connected to a supply battery, the battery monitor mode “LOW” will suffice.

Switching on the cooling box TCX07

Place the cooling box on a firm base.
Push the switch on the control panel (fig.3,) into the “KALT/COLD” position (cooling mode) or the “HEISS/HOT” position (heating mode) to switch on the cooling box.

Switching between cooling and heating TCX07

To switch between the operating modes, push the switch on the control panel (fig.3 3,) into the “KALT/COLD” position for cooling mode or the “HEISS/HOT” position for heating mode.

The green operating display (fig.3 4,) or the red operating display (fig.3 2,) lights up and the cooling box starts cooling or heating.

TCX14, TCX21, TCX35

To switch between cooling mode and heating mode, press the HOT/COLD button (fig.4 4,).

NOTE
The control unit of the cooling box has a memory function. It memorizes the selected temperature range for each mode (cooling and heating). Thus the temperature range which was previously selected in the respective mode is set again with each switching on or switching over.

The blue operating display (fig.4 3,) or the red operating display (fig.4 2,) lights up and the cooling box starts cooling or heating.

Selecting the temperature (TCX14, TCX21, TCX35)

The temperature status display (fig.4 5,) indicates the selected temperature. With an increasing number of illuminated LEDs, the cooling or heating intensity also increases.

NOTE
The following temperature indications are subject to tolerances and are dependent on the measuring position.

Temperature at interior center at approx. 25 °C ambient temperature:

| Temperature status display (fig. 4 5, )|

Interior temperature

---|---|---

Cooling

| 7 illuminated LEDs| approx 1 °C (TCX14)

approx 3 °C (TCX21, TCX35)

1 illuminated LED| approx 17 °C (ECO mode)

Heating

| 7 illuminated LEDs| approx 65 °C
1 illuminated LED| approx 48 °C

To select the temperature, press the button (fig.4 6,) repeatedly until the desired number of LEDs lights up.

Switching off the cooling box

NOTE
When you stop using the cooling box, disconnect it from the mains.

TCX07

Push the switch on the operating panel (fig.33,) into the “AUS/OFF” position to switch off the cooling box.
