ATTENTION
Hold torque wrench at the right angles to the pipe.
This is the only way to the correct function.

Apply alkylbenzene oil (HAB)
for refrigerant leak prevention.
Don´t use mineral oils!

(1) Unscrew the plug of 3-way valve service access (gas). Connect it with manometer
which is suitable for vacuum pump and measuring of vacuum.
(2) Run vacuum pump and evacuate for approx. 15-20 minutes. Don´t open 3-way valves!
(3) Do leak test - wean vacuum pump and control manometer after 60 minutes.
(4) If it is necessary add requested amount of the refrigerant.
(5) If you added refrigerant, disconnect service hose (beware refrigerant leaks -
use protective equipment). If you didn´t add any refrigerant, open a 3-way valve
slowly and carefully (liquid) and fill a pipeline by pressure from the unit for
pressure equalization (check a manometer).
Then you can disconnect service hose and screw a plug of service port.
(6) Open both 3-way valve (liquid first). Reinsert plugs to the original post and tighten
it according to the requested moments shown in the table.
(7) Do leak test of refrigerant circuit with a leak detector.
Do not disconnect
vacuum circuit before
you reach at least
refrigerant pressure.
