Safety functions

Thermal cut out
The solar kit is electrically connected with the thermal cut out safety
of the domestic hot water tank. (refer to "Field wiring" on page 5).
When the thermal cut out safety of the domestic hot water trips, the
power supply to the pump of the solar kit is interrupted so that no
more solar heat can be transferred to the domestic hot water tank.
Domestic hot water tank thermostats (only for UK)
If the domestic hot water tank temperature becomes too high, the
thermostats will stop the pump of the solar pump station (73°C) and
will close the solenoid 2-way valve (79°C).

NSTALLATION OF THE SOLAR KIT

Selecting an installation location

The solar kit is to be installed in a frost free indoor space,
directly connected to the domestic hot water tank.
Make sure the service space is available as indicated in below
drawing.
The space around the unit has to allow sufficient air circulation.
It shall be made sure that in the case of a leak, leaking water will
not cause any damage or unsafe situations.
The equipment is not intended for use in a potentially explosive
atmosphere.
Do not install or operate the unit in rooms mentioned below:
- Where corrosive gas like sulphurous gas exists: copper
tubing and brazed spots may corrode.
- Where volatile flammable gas like thinner or gasoline is used.
- Where machines generating electromagnetic waves exist:
the control system may malfunction.
- Where the air contains high levels of salt such as air near the
ocean and where voltage fluctuates a lot (e.g. in factories).
This applies also to vehicles or vessels.

Dimensions and service space

Service space dimensions below relate to requirements for
installation of the solar kit only.
For service space dimensions of the domestic hot water tank, refer to
the domestic hot water tank installation manual.
NOTE For installation of the solar kit to the EKHWSU150*
domestic hot water tank (UK only), the solar kit will not
fit entirely tight to the tank.
