Notes for installers and service engineers
Caution
 All installation, servicing and maintenance must be carried out by competent and suitably qualified, certified
and accredited professionals and in accordance with all applicable legislation.
 Units should be grounded in accordance with all applicable legislation. Metal and other conductive components
should be insulated in accordance with all applicable legislation.
 Power supply wiring should be securely fastened at the power supply terminals – loose power supply wiring
would represent a fire risk.
 After installation, servicing or maintenance, the electric control box cover should be closed. Failing to close the
electric control box cover risks fire or electric shock.
 Switch ENC1 (indoor unit capacity setting) is factory-set and its setting should normally not be changed. The
only circumstances in which a switch ENC1 might need to be set in the field is when replacing a main PCB.
When replacing a main PCB, ensure that the capacity setting on switch ENC1 on the new PCB is consistent with
the unit capacity given on the unit's nameplate.
