1 Introduction
1.1 Safety notice and warnings
Read these instructions carefully before installation, commissioning, operation, or
maintenance of the device. The given instructions must be followed. Throughout this
manual, the following symbols are used to point out very important information:
Use special caution. The DANGER symbol indicates an immediate
hazard that will result in serious injury or death.
Use special caution. The WARNING symbol indicates a hazard that
may result in serious injury or death.
Use caution. The CAUTION symbol indicates a hazard that may result
in an injury.
Pay attention. The NOTICE symbol indicates a risk of damage to the
equipment, components, or surroundings.
The ‘i’ (info) symbol indicates important information as well as useful
tips and hints.
Keep these instructions as well as the electrical diagrams available near the device.
Installation or commissioning of the appliance is to be carried out by
authorized and trained personnel only, adhering to all local regulations
and requirements.
Wear proper personal protective equipment, such as protective
footwear, gloves, and safety goggles when necessary.
Before any maintenance or servicing, switch off electricity using the
main switch.
M8015 2337EN 3 (20)

Use only fuses with the correct rating.
Do not push items into the air inlet or outlet when the cooling unit is in
operation, as this may result in an injury or damage to the equipment.
Do not direct the air flow directly towards people.
To avoid slipping, keep floor surfaces dry, and seal off or report any
leaks that you detect.
Do not place a heater or other heat source near the unit.
Do not obstruct the air inlet or outlet. Obstructions will lower the unit’s
performance and may cause a malfunction.
If the unit will be out of use for an extended period of time, disconnect
power from the cooling unit’s main switch.
1.2 Delivery contents
Check the contents of the delivery immediately. If some of the
accessories specified in the order are not included in the delivery, notify
the equipment dealer within five days.

Removing the packaging
Remove the cardboard packaging from around the product. Check the unit for
transportation damage. If there is damage, report the damage immediately to the
carrier who delivered the unit.
M8015 2337EN 5 (20)

2 Installation
2.1 Installing cooling unit
Place the cooling unit as high as possible. Cold air flows downwards.
If you bring the pipes to the unit through a wall behind the unit, create a passthrough
for the pipes. The dimensions required for locating the pass through are indicated on
the cooling unit mounting plate.
Installation site requirements
● There are no obstructions 1000 mm in front of or next to the air outlet.
Pos. Distance
X >1000 mm
Y >1000 mm
● There are no heat sources or devices that generate water vapor near the unit.
● The location is optimal for air circulation within the room.
● A condensate drain can be installed conveniently.
● The unit is not next to a doorway.
● The installation height is correct.
Making a mounting box for the cooling unit
A service hatch will be mounted inside the mounting box, at the edge of
the box.
The cooling unit requires a mounting box for installation. This box must be insulated,
as it extends into the cool intermediate floor structure. Make the mounting box from
laminated timber or similar material.
● When making the box, leave room for a service hatch (width: around 200 mm) next
to the cooling unit for making connections and bleeding pipes.
Minimum mounting box width and length:
● Ck5: 850 mm
● Ck9: 1150 mm
6 (20) M8015 2337EN

Installing mounting hardware inside the mounting box
When using screws instead of threaded bars to fasten the unit, install
mounting supports inside the box.
The cooling unit can be fastened to the mounting box either with threaded bars or
screws.
When using threaded bars to fasten the cooling unit, fasten installation supports to the
roof of the box.
● Select a secure mounting method based on the mounting box material.
● Mark the mounting locations for the cooling unit using the cardboard template
included in the delivery.
● Do not tighten the nuts after installing the threaded bars.
● Install washers as shown in the image.
Cooling unit installation
1. Fasten the mounting box between ceiling structures.
2. Carefully lift the cooling unit into place and mount corner brackets onto the threaded
bars.
3. Adjust the height using the washers and nuts. Consider the final height of the ceiling
lining.
4. Tighten the fastening nuts.
5. Fasten the grille in place with the supplied fastening screws.
Alternatively, fasten the unit with screws to the mounting supports inside the box.
2.2 Pipe installation
Make the pipe connections as shown in the piping diagram. Check the connections. To
prevent condensation, carefully insulate the pipes and pass throughs.

Condensate tray installation
The condensate tray ensures that any condensate from pipe joints is led back into the
unit, preventing moisture damage to any surrounding structures.
1. Remove plastic plugs.
2. Install the condensate tray as shown in the image.
A: insulation
3. Insulate the condensate tray.
Condensate drain installation
● To prevent air pockets, cut the condensate drain as short as possible and use a
downward slope (min: 2%).
● Minimum water seal depth: 50 mm.
● The highest point in the condensate drain must not be higher than 200 mm from the
top of the cooling unit.
● Carefully insulate the condensate drain pipe.
● If there are several cooling units in the room, you can chain the condensate drain
pipes as shown in the image.
2.3 Electrical installation
To access the control unit, remove the grille and the metal cover plate as shown in the
image. Make the electrical connections according to the electrical diagrams.

4 Maintenance
4.1 Tasks at the start and end of the heating season
At the start of the cooling season
● Install new batteries in the remote control.
● Check that the cooling unit is installed correctly.
● Check that the cooling unit’s air flow is free of obstructions.
● Check that there are no bends, dents, or blockages in the condensate drain pipe.
● Do not start the cooling unit without air filters. Unfiltered air may cause issues in the
unit’s operation.
At the end of the cooling season
● Turn off power from the main switch.
● Clean the cooling unit and the air filters.
● To remove moisture from inside the unit, run the fan with the FAN function for 2–3
hours.
● Remove the batteries from the remote control.
Outside the cooling season, it is recommended to run the equipment for a short time
every 2 months. This will lengthen the life of the circulation pump.
4.2 Cleaning the air filter
Clean the air filter regularly. If the air filter is dirty, air flow will be weaker, which will
increase power consumption. In extremely dusty environments, clean the air filter once
every two weeks or as often as necessary. The blue air filter prevents bacteria and
mold from growing in the dirt captured by the air filter.
1. Detach the grille by turning the fastening screws (2 pcs) one quarter of a turn.
2. Open the grille and detach the filter from the grille.
3. Vacuum the air filter.
4. If necessary, wash the filter with mild detergent. Dry carefully before reinstalling.
5. Reinstall the filter, lift the grill back up to its normal position, and secure with the
fastening screws.
M8015 2337EN 15 (20)

4.3 Cleaning the cooling unit
Carefully clean the air outlet and fan. If the air outlet or fan are dirty, clean with a moist
towel. If necessary, use mild detergent. Dry with a dry cloth.
Do not use solvents or polishing compounds for cleaning.
4.4 Troubleshooting
Problem Cause/corrective action
The cooling unit does not start. Check the wires for damage.
Check that the circuit breaker has not tripped.
The unit works but doesn’t provide
enough cooling.
Check the room temperature setting.
Check if the air filter is dirty or clogged.
Check if apartment doors or windows are closed.
Check if air flow from the cooling unit is blocked.
Check if the unit’s brine circulation is blocked.
Check the brine circulation for air bubbles.
Check that the brine circuit pump is operating correctly.
There is steam coming out of the
unit when the unit is in operation.
Water vapor may form when hot indoor air and cold cooling air
become mixed.
The remote control does not work. Check the remote control’s batteries.
