Danger of Electric Shock.
If this warning is not observed it can lead to injury or death.
Before carrying out maintenance on the unit it is important to always turn the main switch off
and lock it in the off position.
The unit may have more than one power switch.
Reduce the risk of injury!
If this safety instruction is not observed it can lead to injury. Sheet metal edges may be sharp
or have burrs.
Use suitable protective clothing, safety glasses and protective gloves when handling, cleaning
and carrying out maintenance of this product.
SDX
e indoor unit for heat pump is available in two sizes: SDX12 and SDX22
e SDX can be used with an outdoor unit to heat and cool dierent premises such as warehouses, shops, and
commercial facilities. It can also be used well in dusty environments.
SDX AC has the protection class IP44, SDX EC has the protection class IP54.
For the technical data of the indoor unit SDX, see Appendix A.
Design
e SDX is supplied in galvanised white painted sheet steel with cooling and heating functions.
Maintenance even in dusty places is minimised thanks to the coil element with copper pipes and aluminium ns with a 4 mm pitch.
e aluminium ns have a hydrophilic coating to ensure optimum water repellent at cooling operation.
Control
e SDX does not have its own controller, but is controlled by the external element and its control device.
Dimensioning of external element and heat pump convector/internal element
When combining the outdoor unit with the indoor unit SDX, it is important that the internal volume of the SDX coil
meets the recommendations of the outdoor unit manufacturer for best and safe operation.
It is also possible to connect several indoor units to one outdoor unit.
In doing so, it is necessary to proceed in accordance with the instructions of the outdoor unit manufacturer.
Accessories
As SDX accessories, there are air deectors with blades made of aluminium, which directs the air to the sides.
e name of the air deectors is SDB12 resp. SDB22.
Installation
e refrigerant element must be installed by a certied refrigeration technician.
e electrical installation must be carried out by a qualied electrician.
e indoor unit must be installed at least 850 mm above the oor so that infants cannot reach the moving parts of the fan motor.
GB
Use

mental disabilities as well as those who lack any experience – provided that they have received
detailed instructions of the appliance’s functions and any risks.
Children must not play with the appliance. Cleaning and maintenance must not be performed by
children without proper supervision.
Children under three years of age should not be near the appliance without constant supervision. Children
between three and eight years old may only turn on/shut off the appliance if it is located in a suitable
position and they have received instructions about the proper course of action, or are being supervised.
They must also be informed of possible dangers.
Children between three and eight years old may not connect the device, change its settings or
perform care/maintenance.
WARNING - Parts of this appliance can get hot and cause burns. Children and vulnerable people

INSTALLING THE WALL BRACKET
1. Install the wall brackets with the hole facing the fan; see marking in Fig 1.
is hole is for a cable tie for the cable/cables of the fan motor.
2. e indoor unit must be mounted with the pipe connections on the left side.
Make sure that the indoor unit is horizontal both in width and in depth; see the arrows in Fig. 2.
3. Pull o the entire protective lm from the white painted sheets.
CONNECTING TO THE OUTDOOR UNIT
1. e 3/8” copper pipe for the liquid connector of the coil element is marked in Fig. 3 with a yellow arrow.
SDX22 has a 1/4” are coupling, but this must not be used. Cut it o and solder the liquid connector.
e gas connector is a 5/8” copper pipe marked with a red arrow.
2. NOTE! e coil comes pressurised with dry air. Carefully remove the rubber plugs on the coil connection pipe, see gure 4.
Use nitrogen inside the copper tube to avoid oxidation, during soldering.
Fig. 5 Fig. 6
3. Pull o the rubber seal from the connection pipe and protect the sheet against discolouration with a ame retardant, see Fig. 5.
Attention! Make sure the nitrogen can freely exit so that no overpressure occurs during soldering.
4. e sensor for the liquid pipe is installed outside the internal element frame, see Fig. 6.
Use contact paste and straps with metal locking, insulate with insulating tape.

8. e condensate drain has a G1/2” connection, see Fig. 11. If the drain is connected to the oor drain with a hose, no water
seal is required. If the condensate drain is connected directly to the drainage system, a water seal must be used to prevent the
escape of bad odours.
9. e air deector can be turned by 180° in case the indoor unit is positioned low (at least 850 mm above the oor) or if the air
is to be directed upwards. Loosen the eight screws with a 1/4” hexagon head and turn the air deector, see Fig. 12.
Fig. 7 Fig. 8
Fig. 9 Fig. 10
5. Attach the supplied straps in the hole on the inside of the wall bracket where the fan motor cable/cables is routed, see Fig. 7.
6. Fix the motor cable/cables with the straps, see Fig. 8. en install the control box on the wall.
7. If the control equipment of the outdoor unit is equipped with a separate room sensor, it can be xed with a smaller
cable tie on the inside of the bracket, see Figs. 9 and 10.

ELECTRICAL CONNECTION
e indoor unit is connected to 230VAC via the junction box. To minimize fouling of the heater, the fan should stop when there
is no need for heating or cooling.
AC MOTOR
According to. picture 13.
EC MOTOR
According to. picture 14. Wiring diagram for the EC fan can be found in Appendix B.
ACCESSORY
An air deector is available as an accessory for the SDX, which directs the air to the sides, see Fig. 15.
It is screwed into the of the top and bottom plates with self drilling screws.

MAINTENANCE/CLEANING
Before starting maintenance/cleaning, the indoor unit must be de-energised.
Maintenance/cleaning must be carried out by a maintenance company or a qualied person.
Attention! e air distribution plate on the indoor unit must always be installed, otherwise the heat capacity drops signicantly.
Even with comfort cooling, the capacity decreases, and there is a great risk in the absence of the plate that condensate enters the
element with the air.
e coil of the indoor unit has a 4 mm n pitch, which minimises maintenance. However, it must be cleaned if dust or dirt has
accumulated on the fan, the air distribution plates or the coil. Otherwise the eciency will be impaired.
e intervals at which the indoor unit should be cleaned depend on the type of operating environment.
Clean the coil more thoroughly if the indoor unit is used for comfort cooling.
Fig. 16
Fig. 17 Fig. 18
1. To clean, open the ap, see Fig. 16.
2. Pull the air distribution plate towards the ap opening and unhook it, see Fig. 17.
3. Move the air distribution plate towards the fan motor; see blue arrow in Fig. 18. Release the lower part of the plate and turn it
in the direction of the red arrow so that it detaches from the lower holder.

6. If the air conditioner is cleaned with cleaning spray, rst remove the air deector or turn the air deector blade all the
way up, see Fig. 21.
7. Place liquid-absorbing paper or the like on the bottom plate, which absorbs the cleaning spray and rinsing liquid, see Fig. 22.
8. Proceed accordingly on the inside, see Fig. 23.
9. Apply cleaning spray to the entire coil, see Fig. 24. Follow the instructions on the spray bottle.
Protect the fan motor from cleaning spray and spray uid.
10. After cleaning, reinstall the air distribution plate and cleaning ap.
Make sure that the air distribution plate is correctly installed and held in the correct position by the springs.
Fig. 19 Fig. 20
5. Clean the fan grille, fan motor, fan motor air vents, and coil with a soft brush and a vacuum cleaner.
en clean the drain plate (Fig. 20). Make sure that the condensate drain (green arrow) is free from contamination.
4. Hold the air distribution plate at an angle and take it out, see Fig. 19.
Make sure that you don´t damage the coil!
