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 scale only to continuously monitor the
recovery tank weight. Use only approved tanks for refrigerant recovery. An overfilled 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 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 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 a filter should be used. It is recommended that an in line
suction filter be used on the inlet side of Recovery System. A recommended type is Sporlan “Catch-All”
series of proper size. Filter should be changed often.
DANGER! EXPLOSION RISK!!!
DO NOT RECOVER FLAMMABLE REFRIGERANTS
FOR DIRECT VAPOR OR LIQUID RECOVERY
(Refer to fig.1) Connect System per fig. 1 and following instructions
1. Make sure on-off switch is off, “O” pushed in. Connect system to grounded power connection.
If equipped, push “HPCO” reset button on front panel of system. This switch will “trip” (shut Recovery
System off) if Recovery System is pressurized above 38 bar (550 psi).
2. Turn
INLET
(blue color) valve to
CLOSE
position. Turn center valve (yellow color) to
RECOVER
position.
3. Turn
OUTLET
(red color) valve to
