Filling the internal refrigerant cylinder

4.10.1

Preparation

Before the ACS 651/751 can be used, the internal re-
frigerant cylinder must be filled with liquid refrigerant.
i
Use R134a UN 3159 refrigerant.
The refrigerant can be procured from the local gas
supplier. The refrigerant is normally stored and
transported in cylinders with connection fittings.
Check the type of connection fittings for the "external"
refrigerant cylinder. Follow the instructions below for
filling the ACS 651/751 refrigerant cylinder:
R
Refrigerant cylinder with one shut off valve: Always
turn the "external" refrigerant cylinder upside down
when filling the ACS 651/751 refrigerant
cylinder. This is to ensure that the liquid refrigerant is
transferred into the ACS 651/751 refrigerant cylinder.
R
Refrigerant cylinders with two shut off valves:
$
Using the adapter kit, connect the ACS 651/751
refrigerant cylinder to the external refrigerant
cylinder.
$
Always place the "external" refrigerant cylinder
with the connection fittings facing upward when
filling the ACS 651/751 refrigerant cylinder.
!
The "internal" refrigerant cylinder should not be
replaced unless there is a major damage. The "inter-
nal" refrigerant must always be topped up using an
external refrigerant cylinder.
1. Move the ACS 651/751 to a flat, vibration-free sur-
face.
2. Apply the brakes.
3. Connect the power cable to the mains supply.
