Maintenance of heat pump units
Read chapter
carefully before performing any maintenance on the heat pump unit.
To ensure that the heat pump unit operates without problems throughout a long service life, the system
of maintenance presented in the following instructions must be followed.
Daily maintenance is normally performed by operating personnel. Other maintenance and service tasks,
which require the refrigeration system to be opened, must be performed by competent personnel.
Maintenance can be divided into:

Daily maintenance consists of visual inspections.
•
Inspect the heat pump unit, and check that both noise and vibrations are normal.
•
To observe trends, it is recommended to enter the observed operating data into a log-
book, see subsection

within the permissible ranges. Compare them with previous values to detect trends.

check that the heat pump is running properly: check for fouling of heat exchangers, dirt
in filters, etc.
Maintenance intervals are described in detail in the compressor manual.
