COMMISSIONING
TO FILL AND TURN ON THE WATER HEATER
The power supply to the water heater and controller must not be switched
on until the water heater is filled with water and a satisfactory megger
reading is obtained.
Warning: This water heater contains electronic equipment and 500 V
insulation tests must only be conducted between actives and earth and between
neutral and earth. An active to neutral test WILL damage the electronics.
Commissioning Procedure
– Standalone Heat Pump
Configuration
Perform this procedure to commission a single (standalone) heat pump.
If the system is comprised of multiple standalone heat pumps, perform this
procedure for each heat pump.

Open all of the hot water tap(s) in the building (don’t forget the shower(s))
and supply cock(s) and valve(s) in the system.

Open the isolation valves fully on the cold, return and hot water branches to
the storage tank(s) installed in a bank.

Open the cold water isolation valve on the cold water line to the storage
tank(s).

Air will be forced out of the taps.

Close each tap as water flows freely from it.

Check the pipe work for leaks.

Switch on the electrical supply at the isolating switch to the water heater and
controller.

Set time/tariff control if required.

Reset alarms. Skip this step if there are no alarms.
If the water heater is full of cold water, heating will commence unless the flow
rate of the cold side or the temperature of the cold side or hot side is below the
set point, in which case the auxiliary boost will operate, if installed.
It is important to wait for five minutes after the heat pump has activated to ensure
it continues to operate and is functioning correctly.
