Information About the Device

Device Description

The device is used for spot cooling. The effect of spot cooling is that the cooled room air is directed to a specific point or area. Operating the device is effected via the operating elements on the device.

The device cools the room air by withdrawing warmth. The refrigerant cools down the air coming from the room and in doing so absorbs the heat. The cooled air is supplied via the cold air duct into the room where the device is positioned. Water vapour contained in the room air precipitates on the evaporator fins as condensation or rime. The condensate is transported to the condensation tank.

Device Depiction

The device has the following components:

Transport and Storage

Note: If you store or transport the device improperly, the device may be damaged. Note the information regarding transport and storage of the device.

Transport

Please note that additional transport regulations might apply to devices containing flammable refrigerants. The equipment's arrangement and the maximum number of components to be transported together can be gathered from the applicable transport regulations.

To make the device easier to transport, it is fitted with wheels and a carry handle.

Before transporting the device, observe the following:

Assembly and Start-up

Scope of Delivery

Unpacking the Device

  1. Open the cardboard box and take the device out.
  2. Completely remove the packaging.
  3. Fully unwind the power cable. Make sure that the power cable is not damaged and that you do not damage it during unwinding.

Start-up

When positioning the device, observe the minimum distance from walls or other objects as described in the Technical data chapter.

Inserting the Condensation Tank

Note: Condensate is formed during operation and must be collected with the condensation tank. Before commissioning, make sure that the condensation tank is correctly inserted. Place the opening of the condensation tank underneath the condensate outlet inside the device. Operating the device with a condensation drain hose is also possible.

Connecting the Cold Air Duct

For spot cooling operation, a cold air duct (9) must be connected.

  1. Place the angle flange (11) on the bayonet coupling (12).
  2. Turn the angle flange (11) to the right until the angle flange (11) engages.
  3. Place the cold air duct (9) on the angle flange (11).
  4. Turn the cold air duct (9) to the right until the cold air duct (9) engages.

Diagram Description: Shows the process of connecting the cold air duct. It involves attaching an angle flange to a bayonet coupling, then attaching the cold air duct to the flange, with arrows indicating the direction of connection and locking mechanism.

Connecting the Hot Air Duct

The hot air duct (1) must be connected to the device before use.

  1. Screw the hot air duct (1) onto the device.

Diagram Description: Shows the hot air duct being screwed onto the top of the unit.

Aligning the Air Ducts

The cold air duct (9) can be adjusted by 360°. In addition, the cold air duct can be adjusted upwards and downwards by 150°. The cold air duct can be adjusted by 45°.

Diagram Description: Illustrates the adjustable angles of the cold air duct, showing 360° rotation, 150° up/down adjustment, and 45° adjustment.

Extending the Hot Air Duct (Optional)

Note: Connected ducts must not exceed a length of 3 m. The diameter of the duct to be extended must be 200 mm.

  1. Cut the air duct to size or shorten or extend it as required.
  2. Place the duct to be extended on the other duct while performing a rotating movement to the right.
  3. Wrap sturdy tape around the point where the ducts intersect.

Inserting the Air Filter

Note: Do not operate the device without an inserted air filter! Without the air filter, the inside of the device will be heavily contaminated. This could reduce the performance and result in damage to the device. Make sure that the air filter is installed before switching the device on.

  1. If the air filter (8) has not already been inserted, push the air filter (8) into the designated recess.

Diagram Description: Shows the air filter (8) being inserted into its recess on the side of the unit.

Installation

Note: The opening of the hot air duct in the outdoor area should be positioned so that it is rainproof and preventing any backflow, or so that it is bent towards the bottom. The cold air duct (1) must be directed towards the point or area to be cooled (see chapter Operation). The hot air duct (1) must be placed in the outdoor area so that the warm exhaust air can be directed outside.

Diagram Description: Illustrates the correct placement of the hot air duct for outdoor exhaust, showing it positioned to prevent rain and backflow, and directing warm air away.

Operation

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.

Diagram Description: Shows two scenarios. The first shows a clean interior with a checkmark. The second shows a dirty interior with a cross mark, indicating the need for cleaning.

Cleaning the Air Filter

The air filter has to be cleaned as soon as it is dirty. This is brought to light e.g. by a reduced capacity (see chapter Errors and faults).

⚠️ Warning: Ensure that the air filter is not worn or damaged. The corners and edges of the air filter must not be deformed or rounded. Before reinserting the air filter, make sure that it is undamaged and dry!

  1. Remove the air filter from the device.
  2. Clean the filter using a slightly damp, soft, lint-free cloth. If the filter is heavily contaminated, clean it with warm water mixed with a neutral cleaning agent.
  3. Allow the filter to dry completely. Do not insert a wet filter into the device!
  4. Reinsert the air filter into the device.

Diagram Description: Shows the air filter (8) being removed from the unit.

Condensate Discharge (Manual Draining)

In cooling 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 Condensation tank full LED (13). In addition, an acoustic signal is emitted.

  1. Pull the condensation tank (3) out of the designated recess.
  2. Empty the condensation tank.
  3. Refit the emptied condensation tank into the device.

The condensation tank full LED (13) goes out once you restart the device.
