DANGER!
All electrical installation work is to be performed
by specialist companies. Disconnect the power
supply when connecting the electrical terminals.
n
We recommend installing a main / repair switch
on the building close to the indoor unit. This is
the responsibility of the customer.
n
The power supply is made at the indoor unit, a
control line to the chiller is not necessary.
n
If a condensate pump, which is available as an
accessory, is used in conjunction with the unit,
the pump switch-off contact switches off the
power supply or the valve if necessary.
n
The terminal block for making the connections
and the plug are located behind the unit's
housing on the right side of the unit.
Proceed as follows to establish the connection:
1.
Open the unit cover.
2.
Insert the cables into the unit.
3.
Connect the unit with the controller and
power supply. See electrical drawings.
4.
Mount all removed parts.
NOTICE!
Check all plug and terminal connections to
verify that they are tight and make a permanent
contact. Tighten as required.
NOTICE!
When using a controller from the accessories
range, observe the associated operating
manual.
