ELECTRICAL SET UP
Always use a qualified electrician to perform any electrical work. A licensed
electrician must read the information before connecting.
The Henden Inverter Heat Pump must be earthed and equipotential bonded.
Ensure the power cable and circuit breaker are of suitable size for the heater
being installed. See specification sheet on page 27 for max input power.
Check that there is adequate voltage and current available at the heater
connection to run the unit. Voltage range should be 220–230 volts for single
phase. Voltage ranges outside these parameters will damage the Henden
Inverter Heat Pump.
Ensure power is disconnected during installation or service.
Always comply with the national and local electrical codes and standards.
Ensure electrical cable size is adequate for heater requirements at the
installation location.

Inverter Heat Pump
INSTALLATION
Using the 40mm tail supplied,
connect the inlet of the Henden
Inverter Heat Pump downstream,
after the pool pump and filter.
Create a flow bypass between the
inlet and outlet pipework to ensure
optimal efficiency. See an example
of this using 3 valves adjacent.
Using the 40mm tail supplied,
connect the outlet upstream before
any chlorinators, acid injection
or other chemical dosing systems.

FIRST TIME START UP
To adjust the bypass and calibrate the
flow rate, open all isolating valves.
Fully close the flow bypass and switch
the Henden Inverter Heat Pump
to the maximum temperature.
Wait 3–4 minutes until the
Henden Inverter Heat Pump is
at 100% capacity.
Slowly open the flow bypass valve to
increase the temperature differential
between the inlet and outlet. Closing
the bypass valve will decrease the
temperature differential. Adjust until
optimum differential of 2–3 °C is
achieved.
Handy Tip! Wait two minutes between
each adjustment.

After the compressor has been
running for a few minutes, the air
leaving the Henden Inverter Heat
Pump should be 5–10°C cooler than
the ambient air temperature.
11
To test the flow switch, ensure
the Henden Inverter Heat Pump is
operating, then turn the pool pump
off. If the flow switch is working,
the Henden Inverter Heat Pump
should turn off automatically
and the control panel should
display E3 indicating no flow.

TYPICAL INSTALLATION
Flow switch activated heating
The Henden Inverter Heat pump can be left in an “ON” state and will
activate/ deactivate the heating process using the inbuilt flow sensor.
While the circulation pump is running, the Henden Inverter Heat Pump will
continue to monitor the flow and temperature.
When the Henden Inverter Heat Pump detects a loss of flow the Heater will power
off and an E3 – ‘Low Flow’ error message will be displayed.
Once the flow is restored the alarm will clear, and the heating
process will resume.

ALTERNATIVE INSTALLATION OPTIONS
This Henden Inverter Heat Pump contains electrical equipment. Always use a
licensed professional and never remove panels without disconnecting the power.
Please check with the automation system provider that the connection
is a dry contact switch and the best way to install with their equipment.
The Henden Inverter Heat Pump can be paired with an external automation controllers.
To connect the controller, follow the steps below.
3Insert the control wire from the
automation unit into terminals 5 and
6 then re-tighten the terminal screws.
Locate the loop wire in terminals 5
and 6 then loosen the terminal screws
and remove the loop wire.

Handy Tip: If the Henden Inverter
Heat Pump display reads “OFF”
check the heat pump setting in
the external controller.
Handy Tip: If the external controller uses a temperature sensor, set the Henden
Inverter Heat pump to its maximum temperature to allow full override from
external Controller.

Independant circulation pump
Handy Tip: This set up is only when there is dedicated heating pipework which can operate
independent of the filtration system.
Handy Tip: For this set up, it is recommended to install a single power point for the circulation
pump to plug into for any future service work to the pump which may be required.
WARNING: the maximum load for the relay is 10A.

ON
The Henden Inverter Heat pump will now use the inbuilt timers and temperature
sensor to control the power to the outlet.
a. If the pool reaches the set temperature, the Henden Inverter Heat Pump will
switch off relay to stop the circulation pump.
b. While the timer is still active, the circulation pump will run for 2 minutes every
hour to test the water temperature. If the temperature is 1 degree below the set
point, the Henden Inverter Heat Pump will continue to run the circulation pump
and start the heating process again.
6
Handy Tip: For optimal efficiency Henden recommends adjusting parameter #6 to 100.
This will force the Henden Inverter Heat Pump to operate at 100% and reduce the time
the circulation pump is required to run. To modify the parameters, refer to page 28.
ALTERNATIVE INSTALLATION OPTIONS

19HENDEN – INSTALLATION & OWNERS MANUAL
Inverter Heat Pump
Flow activated with Chlorinator override controller
An onboard pump output relay can activate the main filtration pump by using it in
combination with a “Chlorinator override controller”. This allows the Henden Inverter
Heat Pump to run past the chlorinator timers and prevent over-chlorination when further
heating is required.
Handy Tip: This set-up is best when only single pipework is available from pool and
doesn’t have individual heating pipework.
ALTERNATIVE INSTALLATION OPTIONS
Access the electrical terminals using
the steps from page 14.
1
Locate the termination points labelled
P1 and P2 from the on-board relay &
connect the two–core cable from the
Chlorinator override controller.
2
The Chlorinator override controller
will then provide power to the
circulation pump when it receives a
signal from either the Chlorinator or
the Henden Inverter Heat Pump.
