DANGER
Hazardous Voltage - Risk of Electrocution.
Turn Off the power from main isolator before proceeding with any service work of the unit. Observe proper
LOCK-OUT/TAG-OUT (LOTO) procedures for electrical appliances in order to prevent accidental switching-on of the power
supply. Extreme care and caution must be observed should there be a need to work on live circuit.
WARNING
This air conditioning unit contains R-32 refrigerant (CLASS A2L) which is mildly flammable.
Thoroughly read and understand the accompanying
R-32 Safety Guide
for installation and maintenance instructions.
Installation, service, maintenance, repairs and decommissioning of this unit must be performed by a licensed HVAC technician;
qualified to handle R-32 refrigerant.
R-32 refrigerant is odorless if the refrigerant gas comes into contact with fire, it may emit a poisonous gas.
Appliance shall be installed, operated and stored in a well ventilated area:
• where the room size corresponds to the room area as specific for operation.
• without continuously operating open flames (for example an operating gas appliance) and ignition sources (for example an
operating electric heater).
• away from other potential continuously operating sources that known to cause ignition of R-32 refrigerant.
CAUTION
Beware of Rotating Fans!
Ensure that indoor and outdoor fans are isolated and have come to a complete stand still before servicing the equipment.
Beware of pinch point and sharp edges which can cause cutting injury. Secure the fans against accidental contact.
Always wear appropriate PPE and remove any dangling jewellery and protect long hair by wearing a cap. Ensure that no loose
clothing can be caught / entangled in moving parts.
VISUAL INSPECTION AND WORK ASSESSMENT
Work areas and conditions must first be assessed and evaluated for any potential hazardous conditions. It is also important to be
familiar with the unit parts and components before proceeding with any service task.
NOTE
Fuse Specifications
The air conditioner’s circuit board (PCB) is designed with a fuse to provide over current protection. The fuse specifications,
T3.15A/250VAC
is printed on the circuit board
For the units with R-32 refrigerant , only the blast-proof ceramic fuse can be used.
05. Installation Information
All service technicians handling this unit must be licensed to handle R-32 refrigerant.
Recover and Recycle Refrigerants
Never release refrigerant to the atmosphere! It is an offence in Australia to do so. Always recover, recycle and reuse
refrigerants. When removing from the system, properly contain and identify refrigerants in its dedicated container for
proper disposal and/or storage. Always consider the recycle or reclaim requirements of the refrigerant before beginning
the recovery procedures. Obtain a chemical analysis of the refrigerant if necessary. For the recovered refrigerant and
acceptable refrigerant quality refer to the existing standards and regulations.
Refrigerant Handling and Safety
Consult the refrigerant manufacturer’s Material Safety Data Sheet (MSDS) for information on proper handling and to
fully understand health, safety, storage and disposal requirements. Use the approved containment vessels and refer to
appropriate safety standards. Comply with all applicable transportation standards when shipping refrigerant containers.
