General
Pipe installation must be carried out in accordance with
current norms and directives.
Only use refrigerant pipes that are seamless, degreased,
deoxidized and suitable for a pressure of at least 42
bar. The pipes must be supplied with at least 8 mm
vapour-proof insulation.
Pipe length
1.5 mThe refrigerant pipes' minimum length
7.5 mThe refrigerant pipes' total length with
standard filling

1. Additional filling of refrigerant can be done when the unit runs in cooling
operation:
For refrigerant pipe 1/4" - 3/8" = 15 g/m
For refrigerant pipe 1/4" - 1/2" = 20 g/m
For information about pipe dimensions, see section
"Technical Specifications" on page 16.
Condensation drain
For condensation removal, the AG-CH10 accessory of
suffient length is required to transport the condensa-
tion to an external drain. See section "Accessories" on
page 14 for further information about AG-CH10.
Connecting the cooling circuit
■
Use the flare method to connect the pipes.
■
Lubricate the contact surfaces and hand tighten, then
tighten the connections using a torque wrench to
obtain a good and secure connection, see installation
instructions on page 8.
■
Check carefully that there is no risk of any leakage
prior to the function test.
