For connections using a single pool circulating pump:
• With your circulation pump connected to your filter,
connect the outlet/return of the filter to the inlet
connector located on the base of the Henden heat pump.
• Connect the pool water return line to the outlet
connector located on the base of the Henden heat pump.
For connections using a secondary pool circulation pump:
• Once all the connections have been made, turn the
circulating pump to “ON” to check water pressure and
to ensure that connections are watertight. The flow rate
should be between 160L/min – 300L/maximum (9.6m3/h –
18m3/h). Correct water flow will significantly improve the
performance and efficiency of the Henden heat pump.
• Should the Henden heat pump be used in conjunction
with a solar pool heating manifold, the water entering
the Henden heat pump should first run through the
solar absorber. Do not plumb the solar absorber after
the Henden heat pump. Henden doesn’t recommend this
practice as solar absorbers can’t typically accommodate
the same flow rates as the Henden heat pump. The solar
absorber may also act to cool water rather than heating,
in cooler weather. A better practice would be to run
separate flow circuits.
• Should the Henden heat pump be used in conjunction with
a Henden chlorinator, the chlorinator cell is required to be
installed after the Henden heat pump. If the chlorinator
cell is installed before the Henden heat pump this will
allow heavily chlorinated water to enter the Henden heat
pump. This will significantly shorten the life expectancy of
the Henden heat pump and may void warranty.
2.4 Electrical Connection
WARNING: The electrical connection
should be done by a qualified electrician
according to national, state and local
city codes or standards. The unit should
be connected to a compatible RCD
(Residual Current Device).
