General Maintenance
1. On a regular basis, wipe off the unit using a
clean cloth to remove grease and dirt.
2. Periodically check internal components for
leaks; over time, fittings can loosen as the unit
is moved. Open the door panel, and trace lines
using a leak detector. Check connections on
the back of the unit. Tighten any loose fittings or
connections you may find.
Electrical Protection
The unit is equipped with a 15 amp circuit breaker
on the back panel. See Figure 9. If the breaker
trips, its button will pop out. A tripped circuit
breaker will cause the unit to lose all power.
Press the circuit breaker button to reset.
Manually Fill the
Internal Storage Vessel (ISV)
This menu item is used to transfer refrigerant from
a source tank to the internal storage vessel.
Note: If a refrigerant source tank remains
connected to the unit during normal operation, the
correct amount of refrigerant will automatically be
maintained in the ISV. The ISV may be manually
refilled, if necessary.
1. Select SETUP MENU. Scroll to TANK FILL and
select START. The unit displays
CONNECT SOURCE TANK TO
TANK FILL HOSE, OPEN TANK VALVE, AND
ORIENTATE TANK TO PROVIDE LIQUID
SUPPLY. PRESS START TO BEGIN OR EXIT TO
ABORT.
2. Connect the fill hose to the liquid connector on
a full source tank, and open the source tank
valve. See Figure 10.
3. Install the source tank, and secure it to the unit
(using the tank strap) in such a way that liquid
refrigerant is supplied to the connection.
4. Press START to begin filling the ISV.
5. The unit automatically stops when the preset
tank fill level is reached. To stop the tank fill
before the preset level is reached, select
PAUSE and EXIT.
