Information about the device

Device description
The device serves the purpose of cooling the room air. It further filters and dehumidifies the air thus creating an agreeable room climate.
The unit cools the room air by withdrawing warmth. The absorbed warmth is emitted to the outside via the exhaust air hose; cooled air is fed to the installation site by means of a fan.
Accumulating condensate drips from the evaporator onto the hot condenser, there it evaporates and then is transported to the outside via the exhaust air hose.
In ventilation mode the device provides the opportunity of air circulation without cooling effect.
In dehumidification mode moisture is withdrawn from the air.
The device operates fully automatically and features a variety of further options. The device can, for instance, be switched on or off automatically with time delay via the timer function.
Operation of the device is possible either via the control panel at the device or via the supplied infrared remote control.
The device was designed for universal and flexible application.
Due to its compact dimensions it can be easily transported and used in all interior spaces.

Activities required before starting maintenance
Warning of electrical voltage
Do not touch the mains plug with wet or damp hands.

• Switch the device off.
• Hold onto the mains plug while pulling the power cable out of the mains socket.

Warning of electrical voltage
Tasks which require the device to be opened must only be carried out by authorised specialist companies or by Trotec.

Refrigerant circuit
Danger
Natural refrigerant propane (R290)!
H220 – Extremely flammable gas.
H280 – Contains gas under pressure; may explode if heated.
P210 – Keep away from heat, sparks, open flames and other ignition sources. No smoking.
P377 – Leaking gas fire: Do not extinguish, unless leak can be stopped safely.
P410+P403 – Protect from sunlight. Store in a wellventilated place.
• The entire refrigerant circuit is a maintenance-free, hermetically sealed system and may only be maintained or repaired by specialist companies for cooling and air-conditioning or by Trotec.

Safety signs and labels on the device
Check the safety signs and labels attached to the device at regular intervals. Replace illegible safety signs!

Cleaning the housing

Clean the housing with a soft, damp and lint-free cloth. Make sure that no moisture enters the housing. Protect electrical components from moisture. Do not use any aggressive cleaning agents such as cleaning sprays, solvents, alcohol-based or abrasive cleaners to dampen the cloth.

Visual inspection of the inside of the device for dirt

1. Remove the air filter.
2. Use a torch to illuminate the openings of the device.
3. Check the inside of the device for dirt.
4. If you see a thick layer of dust, have the inside of the device cleaned by a specialist company for cooling and air-conditioning or by Trotec.
5. Put the air filter back in.

Cleaning the air filter
The air filters have to be cleaned as soon as they are dirty. This is brought to light e.g. by a reduced capacity (see chapter Errors and faults).

Warning
Ensure that the air filters are neither worn nor damaged. The corners and edges of the air filters must not be deformed or rounded. Before reinserting the air filters, make sure that they are undamaged and dry!

1. Remove the air filters from the device.
   

2. Clean the filters using a slightly damp, soft, lint-free cloth.
   If the filters are heavily contaminated, clean them with warm water mixed with a neutral cleaning agent.

3. Allow the filters to dry completely. Do not put any wet filters into the device!

4. Reinsert the air filters into the device.
   

Condensate discharge (manual draining)
In cooling and dehumidification mode condensate is formed, which is mostly discharged via the exhaust air.
The remaining condensate is collected in a container within the housing. The condensate ought to be drained regularly.
If too much condensate accumulates, the device switches off and indicates this via the P1 error code on the segment display (15).

1. Carefully transport or wheel the device to a suitable location for discharging the condensate (e.g. a drain) or position a suitable collection container under the condensate outlet.

2. Remove sealing cap and rubber stopper from the condensate outlet.

3. Drain the condensate.

4. Reinsert the rubber stopper in the condensate outlet and reattach the sealing cap. Ensure the tight fit of the rubber stopper, for otherwise there might be uncontrolled water leakage.
   ⇒ The P1 error code on the segment display (15) will disappear as soon as the condensate has been drained.

Activities required after maintenance
If you want to continue using the device:

• Leave the device to rest for at least 12 hours, so the refrigerant can accumulate within the compressor. Wait 12 hours before switching the device back on! Acting contrary might lead to compressor damage and a malfunctioning device. Any warranty claims will be voided in this case.
• Reconnect the device to the mains. If you do not intend to use the device for a considerable time:
• Store the device according to the Transport and storage chapter.
