GENERAL SAFETY INSTRUCTIONS, cont.

FIRST AID:

If high concentrations of refrigerant are inhaled, immediately remove the victim to fresh air. Call a physician or emergency medical technician. Keep calm.

If the victim is not breathing, give artificial respiration. If breathing is difficult, give oxygen. Do not give epinephrine or similar drugs.



EYE:

In case of liquid contact, immediately flush eyes with plenty of water.



Call a physician.

SKIN:

Flush with water. Treat for frostbite, if necessary, by gently warming the effected area.

CAUTION!

All refrigerant hoses, recovery tanks, refrigerant lines, the R100, and other vessels containing refrigerants should be handled as if under high pressure.

OVERVIEW OF SYSTEM OPERATION

The 1 HP R100 offers significant flexibility to meet your refrigerant handling needs in a compact rugged, powder-coated case.

Careful handling of refrigerant is an important part of servicing air-conditioning and refrigeration equipment. Specific regulations apply to refrigerant handling.

Familiarize yourself with these regulations. a portable tank. As stated in the warnings, overfilling a tank can be extremely dangerous. This unit is equipped with a tank overfill sensor cord. When connected properly to a recovery tank with a 80% float, this device will shut off the unit when the tank float activates (open contacts).

The R100 is designed for direct recovery of liquid or vapor refrigerant. It can also be used for the traditional push-pull, high volume recovery of liquid refrigerant.

Because the refrigerant is combined in a large tank, every technician must be sure which refrigerant is in each tank. Your company procedures should help you determine this. Mixing refrigerants can contaminate a large volume of refrigerant.

Recovery of liquid refrigerant in Vapor

Mode can damage the recovery unit compressor. If you are not sure if liquid refrigerant is present, use the Liquid Mode.

Use care when recovering refrigerant into

CAUTION! WARNING!



This unit should be operated by certified personnel per 40 CFR part

82 subpart F or current equivalent.

Before operating this unit, please read this manual thoroughly. You must understand the procedures outlined in this manual. Failure to follow these procedures could void all warranties.



Before handling refrigerants, read the material safety data sheet (MSDS) from the refrigerant manufacturer.



Inhalation of high concentration of refrigerant vapors is harmful and may cause heart irregularities, unconsciousness, or death. Deliberate inhalation of refrigerants is extremely dangerous.

Death can occur without warning. Vapors reduce oxygen available for breathing and are heavier than air. Decomposition products are hazardous. Liquid contact can cause frostbite. All refrigerant containers, equipment, and hoses contain high pressure.



Contact with refrigerant can cause frostbite.

PUSH-PULL LIQUID RECOVERY

The Push-Pull Liquid Recovery mode is used for transferring large volumes of liquid refrigerant. The R100 “Pulls” vapor from the recovery cylinder and produces high pressure discharge gas that “Pushes” liquid out of a HVAC system into a recovery cylinder. ( see figure 1)

Some systems may not allow push-pull liquid recovery.

If any of the following conditions apply to your recovery job, proceed directly to Vapor Recovery.



Equipment contains less than 8 pounds of refrigerant.



Equipment is a heat pump or other unit with a reversing valve.



Equipment has an accumulator between the service ports used in liquid recovery.



Liquid refrigerant has migrated and the location of the refrigerant is not known.



The refrigerant system does not allow for a solid column of liquid refrigerant to be formed.

When using push-pull recovery, the

R100 will not recover to the required vacuum level in the recovered system

.

Use a sight glass to determine when the liquid is being “pushed” into the recover tank. When liquid refrigerant is no longer visible, switch to Vapor Recovery (see figure 2).

The hose connections for liquid “push” recovery are shown in the figure 1. Perform the following steps for push-pull recovery:

1. Ensure the recovery unit

System Switch

is “OFF” and the power to the system to be serviced is also turned off.

Exchange recovery tank with an empty one. Repeat Steps 3-6.

If the Red LED energizes, the recovery unit is sensing a high-pressure limit. Turn off power and check for restrictions. If tank pressure is above 400 psig, exchange tank.

Repeat Steps 3-6.

7. Turn the

Tank Vapor Valve

to “OFF.”

Wait until suction pressure gauge indicates a vacuum.

6. Monitor the sight glass. When there is no longer significant liquid refrigerant passing through the sight glass, push-pull liquid recovery is complete.

8. Perform

process.

9. Disconnect Refrigerant hoses.

Note:

If the Yellow LED energizes, the recovery tank is full.

Turn off power. Turn off both valves.

10.Proceed to the Vapor Recovery procedure in this manual to remove the remainder of the refrigerant and to evacuate the system to the required vacuum level.

VAPOR & LIQUID (DIRECT) RECOVERY

Vapor or Liquid Recovery is used to pull refrigerant directly out of the system to be serviced. The refrigerant is then transferred to a recovery tank.

Liquid Recovery is used when connecting to the high pressure side of the system to be serviced or any other service port that liquid refrigerant is present.

Either Vapor or Liquid Recovery can be used when connecting to the low pressure side or any other service port that vapor refrigerant is present.

IMPORTANT: If you are not sure whether liquid refrigerant is present, choose Direct Liquid Mode. This mode limits the amount of liquid refrigerant entering the compressor. Recovery of liquid refrigerant in the Vapor Recovery mode can damage the compressor.

If large quantities of liquid refrigerant are expected, use the liquid push-pull method. Push-pull will transfer liquid refrigerant faster than direct liquid recovery.

The hose connections for vapor & liquid recovery are shown in the figure 2. To perform vapor or liquid recovery, please follow the steps below:

1. Turn off power to the system to be serviced.

2. Turn the Suction Valve to “OFF” and the Discharge Valve to “RECOVER.”

3. Connect the recovery unit, the system to be serviced, and the recovery tank as shown in the figure 2. The suction hose can be connected to the liquid and/or vapor service ports.

If you connect to the liquid service port, ensure you use Liquid Recovery.

Also ensure the hose to the tank is connected to the DISCHARGE port of the recovery unit.

4. Open the vapor valve on the recovery cylinder.

5. Turn the discharge valve (right) to

“RECOVER” position.

6. Turn the

System Switch

”ON”. The

Green LED should energize.

7. Turn the suction valve (left) to:

“VAPOR RECOVERY” for vapor recovery from the vapor service port.

“LIQUID RECOVERY” for liquid recovery from the liquid service port.

CAUTION: If unsure of the refrigerant’s phase, always choose the “LIQUID RECOVERY” position.

Note: If the Yellow LED energizes, the recovery tank is full. Turn off power.

Turn off both valves. Exchange recovery tank with an empty one. Repeat Steps 3-

6.

If the Red LED energizes, the recovery unit is sensing a high-pressure limit. Turn off power and check for restrictions. If tank pressure is above 400 psig, exchange tank. Repeat Steps 3-6.

7. After the Suction Pressure Gauge indicates the required vacuum, turn the discharge valve to “PURGE” to remove the remaining refrigerant from the recovery unit.

8. When the Suction Pressure Gauge indicates a vacuum, Turn the SUC-

TION VALVE to “OFF”, Turn off the power to the recovery unit, and Disconnect the two refrigerant hoses.

Recovery and Purge Operations are now complete. The R100 is ready for the next job.
