RG6000-E REFRIGERANT RECOVERY
ADDITIONAL INFORMATION
To achieve the better results, use the tank cooling method to lower the head pressure
on the recovery tank. Repeat as necessary to achieve the desired vacuum level.
NOTE: If there is no liquid in the recovery tank, then the cooling method will not work. In
this case, use an empty tank that has been fully evacuated to achieve the final vacuum
level required.
To maximize recovery rates use the shortest possible length of 3/8" or larger hose. A
hose no longer than 1 meter (3 feet) is recommend. Always remove all unnecessary
hose core depressors and Schrader valves from port connections (using the proper
valve core tool) for maximum throughput. Deformed rubber seals and core depressors
in hoses and faulty or unnecessary Schrader valves can restrict flow by up to 90%.
If the tank pressure exceeds 31,5 bar (450PSI), use the tank cooling procedure to
reduce the tank pressure. When recovering large amounts of liquid, use the
"PUSH/PULL" method of recovery (see diagram below).
CAUTION: When using the "PUSH/PULL" method, you must use a scale to prevent
overfilling the storage tank. Once the "PUSH/PULL" siphon is started, it can continue
and overfill the storage tank even if the tank is equipped with a float level sensor. The
siphon can continue even when the machine is turned off. You must manually close the
valves on the tank and the unit to prevent overfilling the recovery tank.
SET-UP DIAGRAM FOR TANK PRE OR SUB COOLING
PROCEDURE
To start you must have a minimum of
2,5 kg of liquid refrigerant in the tank.
Throttle the Outlet valve so that the
Outlet pressure is 7 bar (100 psi)
greater than the Inlet pressure, but
never more than 31,5 bar (450 psi).
Run until the tank is cold.
