Working on the heat pump
Note
Before commissioning and after repair or maintenance
work, check that the heat pump is in the intended con-
dition.
Danger
Heavy and unwieldy heat pump components
can result in life threatening crushing or break-
ages if they fall or are dropped.
■
Use suitable ropes/slings and lifting gear when
installing/dismantling compressors and heat
exchangers, for example.
■
Wear appropriate protective clothing (e.g.
safety boots) in compliance with applicable
regulations on accident prevention and in line
with trade association recommendations.
Working on the refrigerant circuit
Danger
Direct contact with refrigerant can be harmful to
the skin.
■
Always wear safety goggles and safety gloves
when working on the refrigerant circuit
Note
Work on the
refrigerant circuit
may only be
carried out by a qualified
refrigeration engi-
neer
.
■
Wear suitable protective clothing.
Danger
Refrigerant circuits of heat pumps develop
extremely low (
–
25 °C) and very high (+130 °C)
temperatures. Work on heat pumps can result in
life threatening frostbite and burns.
■
Switch off the heat pump
at least 30 min
before maintenance work.
■
Do not touch the injection valve or compres-
sor. Wear protective gloves if necessary.
■
Wear suitable protective clothing.
Danger
Refrigerant R410A is a non-poisonous gas that
displaces air. Unregulated escape of refrigerant
R410A in enclosed spaces can result in breath-
ing difficulties and suffocation.
■
Never breathe in refrigerant vapours.
■
Ensure adequate ventilation in enclosed
spaces.
■
Prevent open flames.
■
Always observe regulations and guidelines on
handling this type of refrigerant.
