Before commissioning AERO SLM heat pumps, the
heating side must be checked for tightness, rinsed
thoroughly, fi lled and bled carefully. During transport it
can happen that threaded connections can be loosen
inside the heat pump by vibrations. To avoid dama-
ges on the heat pump and the installation area, it is
absolutely necessary that all pipe connections inside
the heat pump are tighten. Please check this during
commissioning.
Commissioning requirements:
- The heating and any storage tank must be fi lled and
bled.
- The screwing must be checked for tightness during
commissioning.
- The electrical installation must be complete and
fuse-protected in line with legal requirements.
- The heat pump may only be switched on if it is fi lled
on the refrigerant side and on the heating side, and
if the electrical connections has been checked.
- During commissioning, the fl ow temperatures must
also be set. The shut-off point 62°C (with refrigerant
R410A) should be checked and the set shut-off
temperature changed if necessary.
- If the heat pump is to be drained on the heating
side, the connection hose on the heat pump return
must be disconnected.
- At air source heat pumps a heating buff er tempe-
rature of min. 20°C must be guaranteed in order to
ensure the required temperature for the reference
defrosting.
