GENERAL INFORMATION

General Safety Instructions

ONLY QUALIFIED SERVICE PERSONNEL SHOULD OPERATE THIS UNIT. SOME COUN-

TRIES MAY REQUIRE THE USER TO BE LICENSED. PLEASE CHECK WITH YOUR LOCAL

GOVERNMENT AGENCY.

DANGER The recovery tank used with this unit contains liquid refrigerant. Overfilling of the recovery tank may cause a violent explosion resulting in severe injury or even death. weight.

CAUTION -

As a minimum, use a scale to continuously monitor the recovery tank

DANGER Avoid breathing refrigerant vapors and lubricant vapor or mist. Breathing high concentration levels may cause heart arrhythmia, loss of consciousness, or even cause suffocation.

DANGER - ELECTRICAL SHOCK

HAZARD Always disconnect power source when servicing this equipment.

DANGER - EXPLOSION RISK recover flamable refrigerants.

related injuries.

Do not

All hoses may contain liquid refrigerant under pressure. Contact with refrigerant may cause frostbite or other

Wear proper personal protective equipment such as safety goggles and gloves. When disconnecting any hose, please use extreme caution.

CAUTION handle with care when moving and using this refrigerant recovery equipment to avoid damaging the refrigerant tubing and components ,or increasing the risk of a leak.

CAUTION To reduce the risk of fire, avoid the use of extension cords thinner than NO. 14 awg. (2,5mm 2 ) to prevent the overheating of this cord please keep length to a minimum.

CAUTION Do not use this equipment in the vicinity of spilled or open containers of gasoline or other flammable substances.

Make certain that all safety devices are functioning property before operating the equipment.

CAUTION: R-1234yf is a Class A2 flammable refrigerant. Do not recover other flammable besides R-1234yf. Minimize leakage when recovering these refrigerants.

USE IN A WELL VENTILATED AREA.

OPERATION

REFRIGERANT RECOVERY

IMPORTANT: Before starting the recover of the refrigerant, a refrigerant identifier should be used to determine the type and purity of the refrigerant. Failure to properly identify the refrigerant could potentially expose the user to danger from flammable refrigerants and health hazards from toxic refrigerants. Cross contamination of refrigerants can also occur and would require special handling of the refrigerant.

1. Connect the TRSA30’s discharge (OUT) port to the vapor port of the 30# DOT recover using the provided discharge refrigerant hose.

2. Connect the TRSA30 to the mobile A/C system using the provided low side service hose. Connect the low side service hose to the unit’s inlet (IN) port. Connect either the R134a or R1234yf Low Side Coupler to the end of the service hose. Connect coupler to mobile A/C system low side port.

3. Connect the Yellow Overfill Sensor Cord to the float built into the 30# DOT recovery tank. Plug the unit’s power cord into a suitable 115V power source.

All connections should be done as shown in Diagram-1.

4. Open the vapor valve on the recovery tank.

5. Start unit by pushing main power switch to the “ON” position. Open the Manual Low

Side Coupler.

6. Monitor the A/C system pressure. Once the integrated low side gauge reaches 20”

HG vacuum, turn the unit off. Disconnect the Low Side Coupler from the AC service port.

7. Close the vapor valve on the recovery tank.

8. Disconnect the discharge hose from the TRSA30 discharge port. A small amount of pressurized refrigerant will be released.

OPERATION

Routine Filter Maintenance

Filter Maintenance: The· unit is equipped with a 100-mesh screen filter. This filter should be checked periodically. A partially clogged filter will slow recovery rate.

Check filter cartridge as follows:

1. Use a 5/8” socket or boxed end wrench to remove IN port as shown in Figure 2.

2. Remove suction port-filter cartridge as shown in Figure 3.

3. Clean cartridge or replace with new cartridge. (CPS #CRXF3)

4. Inspect O-ring. Re-lubricate with compressor oil or equivalent.

5. Place filter cartridge back into suction port fitting.

6. Hand tighten this assembly back onto compressor IN port

7. Use 5/8” socket or boxed end wrench to tighten 1/8 of a turn. Do not over tighten;

O-ring damage may occur.

8. Check connection for leaks.

FILTER DRIER REPLACEMENT IS NOW COMPLETE

Service Parts and Repairs Cautionary Statement

This unit uses ignition proof components thus all service parts for this unit must be

CPS certified and the repair work be done by CPS factory authorized service centers and personnel. This is to minimize the risk of ignition due to incorrect parts or improper service.

OPERATION

Trouble Shooting Chart

Problem: The unit will only pull down to 0 pressure or a slight vacuum.

Solution:

Check all LO side connections for possible leaks. If problem persists, check vacuum level directly on the compressor inlet port.

Solution:

Check pressure differential at 400 PSIG discharge pressure. At 400 PSIG, the unit should pull a minimum of a 5” hg. vacuum. If compressor looses its capability of meeting this differential, the compressor seals may need to be replaced.

Problem: HP Red LED lights up, unit starts for a few minutes then shuts off.

Solution:

The high pressure switch has activated. Make sure the discharge valve and recovery tank valve(s) are open. Check for any other restrictions on the discharge port of the unit. Correct restriction. Restart the unit.

Problem: TOS Red LED lights up and the unit shuts off or will not start.

Solution:

1. Check to make sure TOS cord is properly plugged into the recovery tank float.

2. Check tank weight to verify that the tank is full. Empty or replaced tank.

Problem: The unit recovers at a very slow pace.

Solution:

Check for restrictions on the suction side connections. Make sure manifold valves are open. Overtighted hose connections can collapse the rubber gaskets causing a restriction.
