MAINTENANCE AND SERVICE
DISPOSAL
NOTICE
Do NOT try to dismantle the system yourself: the dismantling of the system, treatment of the refrigerant, oil and
other parts MUST comply with applicable legislation. Units MUST be treated at a specialised treatment facility for
reuse, recycling and recovery.
NOTICE
Maintenance MUST be done by an authorized
installer or service agent.
We recommend performing maintenance at least
once a year. However, applicable legislation might
require shorter maintenance intervals.
1. Overview: Maintenance and service
This chapter contains information about:
● The yearly maintenance of the outdoor unit
2. Maintenance safety precautions
DANGER: RISK OF ELECTROCUTION
DANGER: RISK OF BURNING
NOTICE: Risk of electrostatic discharge
Before performing any maintenance or service work,
touch a metal part of the unit in order to eliminate
static electricity and to protect the PCB.
WARNING
■ Before carrying out any maintenance or repair
activity, ALWAYS switch off the circuit breaker on
the supply panel, remove the fuses or open the
protection devices of the unit.
■ Do NOT touch live parts for 10 minutes after
the power supply is turned off because of high
voltage risk.
■ 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 unit. This may cause electric
shocks or fire.
3. Checklist for yearly maintenance of the outdoor
unit
Check the following at least once a year:
● Outdoor unit heat exchanger.
The heat exchanger of the outdoor unit can get blocked up
due to dust, dirt, leaves, etc. It is recommended to clean
the heat exchanger yearly. A blocked heat exchanger can
lead to too low pressure or too high pressure leading to
worse performance.
