Mounting the device
Important
The machine feet come standard with the machine. When it needs
to be installed on a frame, remove the feet and use the openings
for mounting the machine on the frame.
1 Frame
1. Mount the device on the base or the frame.
2. Use bolts and nuts to fasten the device to the base or the frame.

Hydraulic connections
6.2.1
Connecting the supply and return pipes.
Make sure to use flexible pipes or vibration absorbers to avoid the
transmission of vibrations to the pipework.
Caution
Use UV and bird pecking resistant insulation materials for
insulation that is in the open air.
Use condensate resistant insulation materials for a device with
active cooling.
Use a 4-way valve when the heat pump is used for cooling and
a low cooling flow temperature is required. This allows a reverse
flow over the heat exchanger.
1. Flush the device before connecting the heating pipes.
2. Install ball valves at the pipe connections 1 and 2 to facilitate
disconnecting the device for service.
3. Connect the heating supply pipe to the device at 1.
4. Connect the heating return pipe from the device at 2.
5. Measure if there is a sufficient flow over the condenser with the
appropriate equipment.
6. Install a flow switch, to prevent that the heat pump is operated without
water flow.
Caution
When there is no flow, switching on the heat pump will lead
to severe damage to the heat pump.
7. Install a filter and an air bleeder to prevent air or dirt entering the heat
exchanger.
8. Insulate the pipes
