SAFETY INSTRUCTIONS
ENGLISH
• Use a vacuum pump or inert (nitrogen) gas when doing
leakage test or purging air. Do not compress air or oxygen and
do not use flammable gases.
- There is the risk of death, injury, fire or explosion.
• Make sure the connected condition of connector in product
after maintenance.
- Otherwise, it may cause product damage.
• Do not touch leaked refrigerant directly.
- There is risk of frostbite.
• Copper in contact with refrigerants shall be oxygen-free or
deoxidized, for example Cu-DHP as specified in EN 12735-1
and EN 12735-2.
• Compliance with national gas regulations shall be observed.
(for R32)
• Refrigerant tubing shall be protected or enclosed to avoid
damage. (for R32)
• The installation of pipe-work shall be kept to a minimum. (for
R32)
• A brazed, welded, or mechanical connection shall be made
before opening the valves to permit refrigerant to flow
between the refrigerating system parts. A vacuum valve shall
be provided to evacuate the interconnecting pipe and/or any
uncharged refrigerating system part. (for R32)
• Any person who is involved with working on or breaking into a
refrigerant circuit should hold a current valid certificate from an
industry-accredited assessment authority, which authorises
their competence to handle refrigerants safely in accordance
with an industry recognised assessment specification. (for
R32)
• Do not use means to accelerate the defrosting process or to
clean, other than those recommended by the manufacturer.

SAFETY INSTRUCTIONS
ENGLISH
• Do not pierce or burn. (for R32)
• Be aware that refrigerants may not contain an odour. (for R32)
• Dismantling the unit, treatment of the refrigerant oil and
eventual parts should be done in accordance with local and
national standards. (for R32)
• Flexible refrigerant connectors (such as connecting lines
between the indoor and outdoor unit) that may be displaced
during normal operations shall be protected against mechanical
damage. (for R32)
• Pipe-work shall be protected from physical damage. (for R32)
• Mechanical connections (mechanical connectors or flared
joints) shall be accessible for maintenance purposes. (for R32)
• Ventilated area
Ensure that the area is in the open or that it is adequately
ventilated before breaking into the system or conducting any
hot work. A degree of ventilation shall continue during the
period that the work is carried out. The ventilation should
safely disperse any released refrigerant and preferably expel it
externally into the atmosphere.
• Cabling
Cabling will not be subject to wear, corrosion, excessive
pressure, vibration, sharp edges or any other adverse
environmental effects. The check shall also take into account
the effects of aging or continual vibration from sources such as
compressors or fans.
Operation
• Take care to ensure that power cable could not be pulled out
or damaged during operation.
- There is risk of fire or electric shock.
