Section 2. Operation
2.1. Overview
IMPORTANT:
Do not mix different refrigerants together in one tank.
IMPORTANT:
Before recovering refrigerant, the recovery tank
should achieve a vacuum level of 29.6 in Hg (75 cm Hg) to purge
non-condensable gases. Tanks are typically filled with nitrogen when
manufactured in the factory. This nitrogen must be evacuated
before the first use.
IMPORTANT:
The power switch must be OFF before operation.
IMPORTANT:
A in-line filter should always be used and should be
replaced frequently. Each type of refrigerant must have its own
filter. For optimal results, use only Bacharach replacement filters.
IMPORTANT:
In order to gain maximum recovery speed, a hose with
inner diameter larger than 3/16” (5 mm) is recommended and the
hose should be shorter than 5’ (1.5 m).
IMPORTANT:
For recovering large amounts of liquid, use the
Push/Pull configuration.
IMPORTANT:
After recovering, make sure there is no refrigerant left
in the unit. Refer to the Purge Operation section. Liquid refrigerant
remaining in the unit may expand and destroy components.
IMPORTANT:
If the unit is to be stored or remain unused for any
length of time, completely evacuate any residual refrigerant and
purge the unit with dry nitrogen.
IMPORTANT:
The intake port is equipped with a filter screen. Clean
it before every use to maintain performance.
NOTE:
The low pressure gauge shows the pressure of the intake port
of the compressor. The high pressure gauge shows the pressure of
the outlet port of the recovery unit.
