Trouble Shooting Guide
If there is any problem in the operation of the heat pump, please check the following things prior
to calling for support:
Low or no hot water is left in the
storage tank.
Stop using hot water and wait for about an
hour.
Consider a change of the electricity supply
from off-peak mode (length of power supply
hours may be too short for the water
heating cycle to cover the hot water
consumption).
No hot water
comes out of
water tap
Air removing procedure from the
heat pump system may be
insufficient.
Open the water drain plugs on the heat
pump unit to remove air from the water
circuit. (be careful of burning).
Filter on cold inlet connector
may be blocked.
Check the filter and remove if there is any
blockage.
Temperature
of hot water is
too low
Water flow speed may be
dropped due to the heat pump
piping being bent, crushed or
blocked.
Check if any of the piping is bent or
crushed. Remove any kinks if possible.
If frozen area is found on the piping, melt
the ice on the pipe and provide a heat
insulation.
Air absorption is not sufficient
due to a blockage on the
evaporator.
Remove the object blocking the air flow
through the evaporator (e.g. Fallen leaves,
grass, snow, etc.).
For those problems not listed in the list above, an inspection provided by a skilled engineer
is required.
Please contact the distributor.
Caution:
Do not shut down the electricity supplied to the heat pump system even if you go away from home and
hot water is not in use for a long time. (Do not turn off!)
