1.
Setting up the charging station
Filling the vacuum pump with oil
•
Please note the specifications of the vacuum pump!
Please note! The oil must be changed after every 20 hours of
operation.
Adjusting the gauges
•
Before use, all gauges must be set to 0 using the adjusting screws.
2.
Evacuating
•
Use the manifold hose connections and hoses to connect the charging
station to the cooling device.
Blue valve (b) blue filling hose to manifold connection (f)
for R600a use
Red valve (c) red filling hose to manifold connection (g)
for R134a use
•
Switch on vacuum pump, open yellow manifold valve (a) and blue valve
(b) for R600a or yellow manifold valve (a) and red manifold valve (c) for
R134a.
•
Open (h) valve on vacuum gauge (4).
•
When the ultimate vacuum is achieved, close valve (a) and switch off
the vacuum pump. If the vacuum gauge (4) remains at zero or only
shifts by 2-3 graduation marks, the system is sealed under vacuum.
•
If the indicator on the vacuum gauge (4) moves backwards, towards
1000 mbar (atmospheric pressure) there is a leak in the system. Re-
check that all fittings are tight.
Close all valves after each work step.
3.
Filling with gas
•
Put the refrigerant bottle on the scale and connect the container valve
to the ball valve (6) using the ¼" yellow charging hose (yellow
charging line is included but not pictured).
•
Set weighing scale to 0 by pressing the Tare/Zero button.
•
Open the valve on the refrigerant container.
•
Purge the charging line of ambient air.
•
When filling via the intake (suction) side: open ball valve (6), valves (e)
and (b) for R600a or Open ball valve (6), red valve (c) and refrigerant
valve (e) for R134a.
•
Once the desired filling quantity is achieved, close all valves and run
the cooling device.
4.
Filling with fluid Isobutane R600a
•
Fully retract the needle valve on the bottom of support device (7) turn
counter-clockwise
•
Screw the refrigerant bottle fully in to the stand (7) at (d).
•
Connect small black R600a charging line (j).
•
Screw needle valve clockwise to depress gas bottle valve.
