Checklist

Each installation is different. The checklist below provides a general
description of the installation process.
1. Install and fix the heat pump on a solid surface.
2. Install condensate tube of the heat pump and possibly the pipe trace
heating.
3. Connect heat pump to the indoor unit.
4. Connect CAN-BUS cable to heat pump and indoor unit.
5. Connect power supply of the heat pump.
6. Mount side panels and cover of heat pump.

Mounting method

Assembly of the heat pump

CAUTION
Risk of trapping or injury!
The heat pump may tilt if it is not fixed correctly.
▶ Fix the heat pump to the floor.
NOTICE
Installation problems/faults if installed on sloping surface!
This will hamper the assembly of the side panels and cover.
The condensate drainage and functionality will be impaired.
▶ Make sure that the inclination of the heat pump in the transverse and
longitudinal direction is no more than 1%.
▶ Screw the heat pump to the subsurface using suitable screws.
▶ Align the heat pump horizontally using the adjustable feet.

NOTICE
Residue in the pipework can damage the system.
Solids, metal/plastic filings, flax and thread tape residue and similar
material can get stuck in pumps, valves and heat exchangers.
▶ Keep foreign bodies from entering the pipework.
▶ Do not leave pipe parts and connections directly on the ground.
▶ When deburring, make sure that no residue remains in the pipe.
▶ Before connecting the heat pump and indoor unit, rinse the pipe
system to remove any foreign bodies.
NOTICE
Material damage due to frost and UV radiation!
In case of a power outage the water in the pipes may freeze.
The insulation may become brittle due to UV radiation and crack after
some time.
▶ Use insulation with a thickness of at least 19 mm for pipework and
connections outdoors.
▶ Install drain valves so that the water can be drained out of the lines to
and from the heat pump if it is not going to be used for some time or
if there is a risk of frost.
▶ Use UV and moisture-resistant insulation.
Insulation/Sealing
▶ All heat-conducting pipework must be provided with suitable thermal
insulation according to applicable regulations.
▶ In cooling mode, all connections and lines must be insulated
according to applicable standards to prevent condensation.
▶ Seal wall outlet.
Dimension pipes according to instructions (Tab. 4– 6).
▶ To minimise pressure drops, avoid joints in the heat transfer medium
line.
▶ Use PEX pipes for all pipework between the heat pump and indoor
unit.
▶ To avoid leaks, only use material (pipes and connections) from the
same PEX supplier.
1 2
▶ To make installation easier and to avoid breaks in the insulation, use
of insulated AluPEX pipes is recommended. The purpose of PEX and
AluPEX pipes is to damp vibrations and reduce noise transmission to
the heating system.
3
If materials other than PEX are used, the following prerequisites must be
met:
▶ Install a particle filter which is suitable for use outdoors in the return
to the heat pump directly at the heat exchanger.
▶ Insulate the particle filter and also the other connections.
▶ Establish the connection to the heat pump using a vibration-damping
hose which is suitable for use outdoors and also insulate it.
