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

(for R32)

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
