Bleeding; Maintenance - DeLonghi FRIO 12 Installationsanleitung

BLEEDING

Humid air left inside the refrigerant circuit can cause com-
pressor malfunction. After having connected the indoor and
outdoor units, bleed the air and humidity from the refriger-
ant circuit using a vacuum pump.
(1) Unscrew and remove the caps from the 2-way and
3-way valves.
(2) Unscrew and remove the cap from the service valve.
(3) Connect the vacuum pump hose to the service valve.
(4) Operate the vacuum pump for 10-15 minutes until an
absolute vacuum of 10 mm Hg has been reached.
(5) With the vacuum pump still in operation, close the low-
pressure knob on the vacuum pump coupling. Stop the
vacuum pump.
(6) Open the 2-way valve by 1/4 turn and then close it after
10 seconds. Check all the joints for leaks using liquid
soap or an electronic leak device.
(7) Turn the body of the 2-way and 3-way valves. Discon-
nect the vacuum pump hose.
(8) Replace and tighten all the caps on the valves.
