Make connections at terminals X3.8/X3.9
After
connecting the power supply, one of the follow-
ing components
must
be connected at terminals X3.8
and X3.9:
■
Primary circuit pressure switch and/or frost stat
or
■
jumper supplied
Closing the heat pump
!
Please note
Leaking hydraulic connections lead to appliance
damage.
■
Check for leaks in the internal and on-site
hydraulic connections.
■
In the event of leaks, switch off the appliance
immediately. Drain liquid via the drain & fill
valve. Check the seating of seal rings.
Always
replace displaced seal rings.
!
Please note
If the casing is not securely sealed, this can lead
to damage from condensate, vibrations and
excessive noise.
■
Seal the casing door so it is soundproof and
diffusion-proof.
■
The outer panels must be fitted so as to be dif-
fusion-proof during operation. Only remove the
outer panels for maintenance and service
work.
