▪ Remove the knockout hole (a) in the bottom plate or
cover plate by tapping on the attachment points with a
flat head screwdriver and a hammer.
▪ Optionally, cut out the slits (b) with a metal saw.
NOTICE
Precautions when making knockout holes:
▪ Avoid damaging the casing and underlying piping.
▪ After making the knockout holes, we recommend to
remove the burrs and paint the edges and areas
around the edges using repair paint to prevent rusting.
▪ When passing electrical wiring through the knockout
holes, wrap the wiring with protective tape to prevent
damage.
3 Select the correct accessory pipes, depending on the chosen
route:
▪ Front, side and rear route: short liquid and gas pipes.
▪ Bottom route: long liquid and gas pipes.

▪ Connect the accessory liquid pipe (a) to the liquid stop valve
(brazing).
▪ Connect the accessory gas pipe (b) to the gas stop valve
(brazing).

5 Connect the field piping to the accessory pipes using the
accessory bend pipes (brazing). Mind the orientation of the
bends.
NOTICE
Always protect the surrounding surfaces (e.g. wiring,
insulation foam, …) from heat when brazing.
6 Do the following:
▪ Insulate the liquid piping (a) and the gas piping (b).
▪ Wind heat insulation around the curves, and then cover it
with vinyl tape (c).
▪ Make sure the field piping does not touch any compressor
components.
▪ Seal the insulation ends (sealant etc.) (d).
▪ Wrap the field piping with vinyl tape (e) to protect it against
sharp edges

7 If the outdoor unit is installed above the indoor unit, cover the
stop valves (f, see above) with sealing material to prevent
condensed water on the stop valves from moving to the indoor
unit.
NOTICE
Any exposed piping might cause condensation.
8 Reattach the service cover and the piping intake plate.
9 Seal all gaps (example: a) to prevent snow and small animals
from entering the system.

NOTICE
Do not block the air vents. This could affect air circulation
inside the unit.
WARNING
Provide adequate measures to prevent that the unit can be
used as a shelter by small animals. Small animals that
make contact with electrical parts can cause malfunctions,
smoke or fire.
NOTICE
Make sure to open the stop valves after installing the
refrigerant piping and performing vacuum drying. Running
the system with the stop valves closed may break the
compressor.
