seT-UP InsTrUCTIons
The unit comes with four 60-inch Enviro-Guard hoses with ball valves. Either
blue hose may be used where blue hose connections are called for, and either red
hose may be used for red hose connections.
CAUTION: To prevent personal injury, all valves on hoses must be in
the closed position before making connections.

oPeraTInG GUIdelInes
• The voltage at the unit must be ±10% of the unit’s rated voltage.
• Extension cords must be a minimum of 14 AWG and kept as short as possible.
• To minimize mixing of refrigerants, the self-clearing procedure must be
performed after each recovery operation.
• The low-side gauge on the unit allows you to monitor system pressure and stop
recovery when a deep enough vacuum has been reached. The high-side gauge
allows you to monitor the refillable tank pressure.
• When changing from liquid to vapor, the unit may switch back and forth several
times before staying on vapor. You may notice the liquid light switching and
hear the solenoids opening and closing. This is normal and does not affect the
unit or its operation.
