READ ALL INSTRUCTIONS BEFORE OPERATING FLUSHER
USE ONLY DRY SHOP AIR WITH THIS FLUSHER. ALTHOUGH THE FLUSHER IS
EQUIPPED WITH AN AIR FILTER, CAUTION MUST STILL BE USED TO AVOID EXCES-
SIVE CONTAMINATION OF THE A/C SYSTEM WITH MOISTURE FROM THE SHOP AIR
SUPPLY.
Place the drain valve and control valve in the closed or OFF position. Remove the filler cap at
the back of the machine and install approximately 2 gallons of an approved solvent (VIPER
part # 098-317-100 or HECAT Safe-Flush recommended). Other solvents will work with this
unit, however foaming type solvents are not to be used as they will contaminate the flusher
and stop the pulsing action. If the flushing fluids containing CF 20 or 141 are used they will
dry out the seals in the control valve and are cost prohibitive due to the fact that they evapo-
rate too rapidly and will not recycle well. Fill the flush tank only to the full mark (slot behind
the sight glass) at the sight glass on back of flusher. DO NOT OVERFILL! OVERFILLING
WILL NOT ALLOW FOR A HEADSPACE ABOVE THE SOLVENT IN THE FLUSH TANK.
With the control valve in the OFF position and before connecting shop air to the flusher, drain
the air filter. Connect the shop air supply to the air filter.
Using the flushing adapter kit (Viper part # 134-317-000) supplied with the flusher and the
required A/C system adapters, connect the flusher hoses to the A/C system as outlined in the
following instructions.
The following sequence of flushing and purging operations is recommended. This is to assure
that the remaining solvent is purged from the lowest part of the A/C component being flushed
at the end of the purging cycle.
When flushing a condenser and/or high pressure liquid lines, connect the rubber (discharge)
hose to the outlet side of the component first, then the braided vinyl (inlet) hose to the inlet
side. Perform the flushing operation, as will be outlined later, then reverse the hoses at the
quick couplers and complete the final flushing and purging of the component from the inlet
through the outlet side. The outlet side of the condenser is the lowest side.
When flushing an evaporator, the procedure is just the reverse, as the lowest side of an evap-
orator is the inlet side. This would mean that the final flush and purge would be made from
the outlet side of the component, through the component and out the inlet side.
The sequencing in this manner will assure the maximum efficiency of the flushing equipment.
