AINTENANCE AND SERVICE
In order to ensure optimal availability of the unit, a number of checks
and inspections on the unit and the field wiring have to be carried out
at regular intervals.
This maintenance should be carried out by your local technician.
To execute the maintenance activities as mentioned below, it is only
required to remove the indoor unit cover. See "Opening the indoor
unit" on page 9.

Maintenance activities

DANGER: ELECTRIC SHOCK
Before carrying out any maintenance or repair activity,
always switch off the circuit breaker on the supply
panel, remove the fuses (or switch off the circuit
breakers) or open protection devices of the unit.
Make sure that before starting any maintenance or
repair activity, also the power supply to the outdoor
unit is switched off.
Do not touch live parts for 10 minutes after the power
supply is turned off because of high voltage risk.
The heater of the compressor may operate even in
stop mode.
Please note that some sections of the electric
component box are hot.
Make sure you do not touch a conductive section.
Do not rinse the indoor unit. This may cause electric
shocks or fire.
When service panels are removed, live parts can be
easily touched by accident.
Never leave the unit unattended during installation or
servicing when service panel is removed.
Play it safe!
Touch a metal part by hand (such as the stop valve) in
order to eliminate static electricity and to protect the PCB
before performing service.
DANGER
Do not touch water pipes during and immediately after
operation as the pipes may be hot. Your hand may suffer
burns. To avoid injury, give the piping time to return to
normal temperature or be sure to wear proper gloves.
WARNING
Do not touch the refrigerant pipes during and
immediately after operation as the refrigerant pipes
may be hot or cold, depending on the condition of the
refrigerant flowing through the refrigerant piping,
compressor, and other refrigerant cycle parts. Your
hands may suffer burns or frostbite if you touch the
refrigerant pipes. To avoid injury, give the pipes time to
return to normal temperature or, if you must touch
them, be sure to wear proper gloves.
Do not touch the internal parts (pump, backup heater,
etc.) during and immediately after operation.
Your hands may suffer burns if you touch the internal
parts. To avoid injury, give the internal parts time to
return to normal temperature or, if you must touch
them, be sure to wear proper gloves.
