CHARGING (cont)
If using a large bottle the scale platform can be removed for convenience. First lower
the scale platform to the horizontal position, pull the scale platform away from the unit,
now raise the platform to the vertical position and pull away from the unit. Picture
below shows platform removed from unit.
Switch scale on. Wait for it to initialise then press 'zero'
Place gas bottle on platform and wait a minute until it has settled. Press 'Tare'. The
scale is now ready for charging.
Connect the charge hose (yellow) to the bottle. Ensure all connections are tight and
valves are closed.
Evacuate air from lines using the vacuum pump.
Close vacuum valve and open bottle tap.
Open manifold charge valve(s) as desired to obtain correct charge amount.
Note: As the scale is powered by a 9V battery located in the back of the controller, mains
power is not required for charging. If power is not available for charging purposes the
lines may be purged of air with refrigerant. Where possible evacuate line so as to limit
refrigerant loss to atmosphere.
Note: the scale unit has an auto shut down timer built in. The scale will automatically
switch off 15 minutes after it has been turned on.
Do not leave refrigerant in manifold or lines once charging is complete. Care should be taken so as to
prevent any refrigerant entering the vacuum pump.
