PRECAUTION!
Risk of injury due to refrigerant!
Refrigerant is corrosive and causes cold burns upon
contact with skin.
Therefore:
-
Wear chemical-resistant protective gloves when
handling refrigerant at any time.
-
Wear protective glasses to avoid contact with eyes.
-
Connect the heat pump and the split evaporator with the refrige-
rant lines.
CAUTION!
Environmental damage due to improper assembly of
the refrigerant line!
Refrigerant and compressor oil can leak!
Therefore:
-
Only use tools that are recommended for used in
the cooling unit: Bending wrench, pipe separator,
deburrer and bordering tool
-
Take note of bending radius to avoid bending or
breaking of pipes.
-
To avoid brittle or cracking pipes, do not bend the
pipes repeatedly.
-
In order to reduce loss of pressure and to ensure
return of compressor oil, avoid unnecessary bend-
ing of the pipes.
-
Use appropriate fastening and insulation during
refrigerant line installation.
-
Use only non-cutting tools (special pipe cutting
tools) to shorten refrigerant lines.
NOTE!
The heating pump contains refrigerant for a 20 m
max. length cooling line.
Any shortening or lengthening of the line may only
be carried out by a certified technician. The refrige-
rant dosage must then be checked accordingly.
NOTE!
The technician must check the installation and
mountings of the pipe, and establish a proper con-
nection with the heating pump and the split evapora-
tor.
NOTE!
Ball valves must remain shut (delivery condition)!
