Make sure to ensure strain relief of the cables by
correct use of the PG nipples and PG nuts (to be
mounted on the domestic hot water tank).
Refer to "Accessories supplied with the solar kit" on
page 2, part 6. Positions where PG nipples and PG
nuts need to be screwed in the domestic hot water
tank are indicated on figures 1, 2 and 3 as actions 14.

Commissioning the system before initial start up
Besides the checks before initial start up of the unit (refer to the
installation manual of the unit) you must check the following items on
the solar kit installation before switching on the circuit breaker:
The domestic hot water tank is filled with water. Refer to the
installation manual of the domestic hot water tank.
The circuit connected to the solar kit is filled with water. Refer to
the installation manual of the unit.
The solar collector circuit is filled with glycol. Refer to the
installation manual of the solar circuit.
Make sure the solar kit is properly fixed to the domestic hot
water tank and that there are no leaks.
Field wiring and earthing
Make sure the pump of the solar kit is connected to the domestic
hot water tank as shown in the wiring diagram and the pump
earth wires have been connected properly. The earth terminals
should be tightened.
Ensure that the auxiliary contact of the solar pump station is
connected to the unit.
Ensure the power supply cable from the unit is connected to the
domestic hot water tank.
Mounting of sensors
Make sure the solar panel temperature sensor and the domestic
hot water temperature sensor of the solar pump station are
properly mounted.
Verify that following settings are made on the solar pump station:
Maximum solar panel temperature: ≤110°C
Maximum tank temperature:
- For EKHWS domestic hot water tank: 80°C
- For EKHWSU domestic hot water tank: 70°C
- For EKHWE domestic hot water tank: 75°C
Minimum temperature difference between domestic hot water
tank and solar panel before starting pump operation: ≥10°C
WARNING
Due to heat conduction, the piping between heating circuit
and solar kit connection can become very hot.
For this reason this pipe must be made of copper, at least
0.5 m long and insulated.
Checklist for proper functioning
Following items should be checked to assure proper functioning:
When the temperature of the solar panel becomes 10°C higher
than the domestic hot water tank temperature, the pump of the
solar pump station and the pump of the solar kit will start
(1)
operation.
When the temperature of the solar panel becomes lower than
the domestic hot water tank temperature, the pump of the solar
pump station and the pump of the solar kit will stop operation.
(1) Unless the domestic water heating mode is enabled, the solar priority
parameter = 1 and the heat pump is heating the domestic water tank at
that moment.
Refer to "Configuring your system" on page 9 for more information.
