Security advise for installation
During the installation activities, the installation site and the place of mounting
needs to be ventilated well.
No unauthorised person should enter the installation area during installation ac-
tivities
Do not close the doors or windows!
Do not use open fire, especially cigarettes, no brazing units or open cooking
during installation.
Avoid static charge by wearing cotton clothes and cotton safety gloves.
Place the leak detector (or HC gas alerter/detector) operational in the installa-
tion area!
If there appears a leak within the refrigerant circuit increase the air ventilation at
the installation side. Stop any work immediately and switch off the electrical
power supply.
If damage occurs to the system during installation refer to the local service cen-
tre.
Switch off cell phones during installation. Take care that any other electric de-
vices such as TVs, microwave ovens are switched off during installation.
For installation, service and repair always provide a dry powder fire extinguisher
within the work area.
Before installation
The system contains exactly 200 grams of HC R-290 refrigerant charge. For se-
curity reasons the room for the installation of the indoor unit must have a mini-
mum of room size. This is set to the system of GWH09AA-K5NNA6A at 7 m
2
minimum with 1.8 metre installation height. Refer to the room size selection ta-
ble on the following page.
Assure yourself about the admissible minimum amount of room area be-
fore installation!
Before you unpack the system from the transport box, keep the HC leak detec-
tor ready.
Open up the transport box and produce only a small hole first into the foil in
which the system is shrink-wrapped. Place the gas detector inside the wrapping
and make sure that the detector does not identify the presence of any gas.
Should there be a gas detection refer immediately to the local service centre in
order to organise a replacement system.
Now unwrap the components.
Examine the delivered parts for damages.
For this specific
AC unit, the in-
door room size
should be at a
minimum
of 7 m² !
