Tank Fill Hose Filter Service
The black tank fill hose at the rear of the machine
contains a filter that can be cleaned when it appears
that refrigerant flow is restricted.
When the machine senses low flow, it may display the
following message:
• SOURCE TANK EMPTY, but yet you know the
source tank contains refrigerant, connections are
secure, and the source tank valve is open.
The cause may be that the tank fill hose filter is
plugged.
Cleaning the Tank Fill Hose Filter
1. First ensure that pressure does not exist in the
line. Disconnect the external source tank, and
perform a manual tank fill to capture any refrigerant
in the line.
2. Slowly and carefully disconnect the tank fill hose
from the adapter. There may still be a little pressure
in the line.
3. Disassemble the tank fill hose at the filter housing
as shown in Figure 12.
4. Remove and clean the filter.
5. After the filter has been installed back into the filter
housing, torque the housing assembly to 8.5 N•m
(6 ft. lbs.).
