Care and Maintenance
INLINE FILTER DRYERS
Use a new inline filter dryer on the input side of the G1Single when pumping dirty refrigerant. Refrigerant acts
like a solvent and can collect dirt and debris when it is pumped out of a system. Failure to use an inline filter
dryer can cause damage to the compressor, and will void the warranty on your machine.
While specifications may vary, most Size 032 filters will not be eective for more than 50 lbs. (22.6 Kg) of
refrigerant. Also, once refrigerant has been introduced into the inline filter, it may continue to wear down, and
may not have the same eective capacity if used across multiple jobs. Change the inline filter dryer regularly,
and consult the filter manufacturer for expected capacity.
SCREEN CLEANING AND REPLACEMENT
The G1Single is equipped with a debris screen inside the input fitting. This is the last line of defense for the
recovery machine against any debris that might make it past an inline filter. For best results it is recommended
to clean it before each use. If it becomes worn, replace it immediately.

1. Unscrew Filter Cap from Input Port.
2. Remove screen from Filter Cap.
3. Clean screen and Filter Cap thoroughly. If the
screen is worn or damaged, replace it.
4. Check the O-ring that seals the Filter Cap to the
Input Port. If it is dry, apply a drop of refrigeration
oil. If it is damaged, replace it.
5. Place clean screen into Filter Cap and screw it
back onto the Input port.
PLANNED MAINTENANCE
You can use any standard refrigeration oil (mineral is ideal) to scavenge out dirt and debris, and recondition
the seals. Run the machine with no hoses connected. Using a 1/4” port cap, fill it with refrigeration oil and
hold it up against the input port, allowing the G1Single to suck it in. Place a towel below the output port
to catch any oil spray. This is very helpful aer recovery of burnout systems, and as regular maintenance
depending on the frequency of use.
