SAFETY INFORMATION!
READ CAREFULLY BEFORE USING MASTERCOOL RECOVERY SYSTEM!
1. This equipment is designed to be used by qualified service personnel. The operator of this equipment must be
familiar with air conditioning and refrigeration systems. Do not attempt to operate this equipment until all safety
instructions and operating instructions are read and understood.
2. Always use eye protection (safety goggles) and hand protection (gloves) when working with refrigerants. Other types
of personal protective equipment should also be used.
3. All hoses used for interconnecting system should have shut off valves (manual or automatic) on both ends. Treat all
hoses and connections with caution. Hoses or connections will contain liquid refrigerant or gas under pressure.
Connect and disconnect fittings with caution.
4. Do not pressure test system with air. Some mixtures of air and refrigerant can be combustible or explosive.
5. Recovery tank contains liquid refrigerant under high pressure. Never over fill recovery tank. Tanks should be filled
to a maximum of 80% of capacity only. 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 15240 mm (50 ft) maximum length. If lower
amperage capacity extensions are used an over heat 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 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 another hose to recovery machine outlet. Valve end of hose is connected to recovery tank.
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 the hose from low side connection system to inlet port filter connection. Connect the hose from outlet port of
recovery machine to vapor (gas) connection on recovery tank.
5. 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”).
