12.2.17 ALARM DURING START-UP
An alarm may be triggered during start-up if a
temperature is captured in the condenser that is too
low. The reason for this is that water has been filled in
that is too cold (lower than +5 °C).
Fig. 43 Sight glass
Check the sight glass in the heat pump. Bubbles may be
visible in the sight glass for a few minutes after start-up.
No bubbles should form after a few minutes. If bubbles
continue to form, this is a fault indicating a lack of
refrigerant. Under certain operating conditions, bubbles
can form even if there is no refrigerant shortage.
