should be filled to a maximum of 80% of capacity only. Use scale and connection to recover tank’s float
switch to make sure tank is not over filled. Recovery system with automatic shut down switch must be
connected to recovery tank float switch for proper operation. Use only approved tanks for refrigerant
recovery. An over filled tank can explode causing serious injury or death.
6. Do not breath refrigerant vapors and/or lubricant vapor or mist. Breathing high concentrations of these
substances will cause severe health problems. Always use Recovery system in a well-ventilated area.
7. Do not use this Recovery System in the vicinity of spilled or open containers of flammable substances
(gasoline, solvents, etc.).
8. If electrical extension cord is used, it must be 14 AWG or larger and 50 feet maximum length. If lower
amperage capacity extensions are used an overheat condition and fire hazard could occur.
9. Make sure system is electrically connected to a properly grounded power source. Always disconnect
system from power source when servicing system.
10. Some governmental agencies require licenses or certification to work with refrigerants and this recovery
equipment. Use this system only if operator has proper license or certification.
11. This recovery system is not to be used with any type of flammable refrigerant or flammable gas.
12. The Recovery System includes a fine screen filter at the inlet port. Since many recovery operations
involve transferring contaminated refrigerants, the recovery system has an inlet in-line filter-dryer
installed at the inlet port. Filter should be changed often or whenever contamination prevents proper
operation of recovery system.
DANGER! – EXPLOSION RISK!!!
DO NOT RECOVER FLAMMABLE REFRIGERANTS
OPERATING GUIDE FOR DIRECT VAPOR OR LIQUID RECOVERY (Refer to fig.1)
Note: A. Connect blue hose (with coupler) to inlet filter. When Recovery Machine is in use, always
keep hose and coupler assembled to inlet filter. When hose is removed from filter, use
protective cap to seal inlet filter.
B. Connect yellow hose to recovery machine outlet. Valve end of hose is connected to
recovery tank. If recovery machine shuts off due to full tank, close valve in yellow hose,
shut off machine, replace and connect empty recovery tank to yellow hose and restart
Recovery Machine. If Recovery Machine does not start refer to Steps 8 and 9.
1. Make sure on-off switch is off, “O” pushed in. Connect system to grounded power connection.
2. Turn INLET (blue color) valve to CLOSE position. Turn center valve (yellow color) to RECOVER position.
3. Turn OUTLET (red color) valve to OPEN position.
4. Connect blue hose from low side connection system to inlet port filter connection. Connect hose from
outlet port of recovery machine to vapor (gas) connection on recovery tank.
5. Connect float switch cable from recovery machine to recovery tank.
NOTE: Recovery tank must have a maximum capacity switch to prevent over filling of tank. Recovery
system will not operate if float switch cable is not connected. Purge air and moisture from system by
bleeding lines, using vacuum pump or purge function of recovery system.
6. Open the vapor valve on the recovery tank.
7. Turn INLET valve on Recovery System to OPEN.
8. Turn on Recovery System (push power switch “I”).
9. Start recovery system.
10. Observe operation of system. In rare instances “slugging” may be apparent (loud compressor noise or
high vibration). If this condition is apparent turn inlet valve to LIQUID position. System can be run with
this setting continuously. It is suggested that operator periodically turn inlet valve to OPEN position and
