Emptying Internal Tank; Cleaning The Filter Screen; Troubleshooting - MasterCool MASTERCLEANSE series Bedienungsanleitung

PURGING PROCEDURE:
If a purge selection valve is available:
1. Turn the purge selection valve to the preferred purge source.
a. To use an external purge gas source (Nitrogen is preferred. If air is used, the air source must be clean and dry.),
attach the gas source to external "PURGE GAS CONNECTION"
90 PSI (6.2 Bar).
• Turn the purge selection valve
b. To use the internal nitrogen source, screw a bottle of nitrogen onto the regulator.
• Turn the selector valve
2. Turn the "FLUSH" valve
3. Check that all connections are tight.
4. When ready to purge turn the "PURGE" valve
5. Continue purging until all of the flush fluid is out of the system and the system is dry.

EMPTYING INTERNAL TANK:

1. Make sure hoses are purged of flushing fluid.
Note: To purge the hoses without an item to flush, use a 1/4" SAE flare male union (Mastercool part number 90633) to
connect both ends of the hoses together.
2. Attach a hose to the "EXTERNAL TANK" connection
3. Run the hose to an external tank for dirty flush storage and disposal.
4. Turn the "FLUSH" valve to the horizontal position.
5. Turn the "EXTERNAL TANK" valve
Note: Fluid will start flowing as soon as the valve is opened.
6. Follow purging procedure with "EXTERNAL TANK" valve open to purge the flushing fluid out of the pump as well as the
tank. The valves will be in "Valve Position 3."
Note: Emptying the tank by putting the hose for fluid coming from the machine
pump on works, but, there is a risk of running the pump dry and damaging it. We do not recommend empting the tank
this way.

CLEANING THE FILTER SCREEN:

1. Purge the hoses to empty any flush fluid from the filter screen.
Note: To purge the hoses without an item to flush, use a 1/4" SAE flare male union to connect both ends of the hoses
together.
2. Hold a rag or container under the filter screen.
3. Unscrew the filter screen cap by turning it counter clockwise, looking from the top.
4. Unscrew the screen and clean it.
Reassembly
5. Replace the filter screen.
6. Put some light oil on the filter screen cap threads and O-ring.
7. Screw on the filter screen cap hand tight.
Optional Procedure
1. Disconnect the tube from the "FLUSH RETURN CAP"
2. Disconnect the tube that goes from the bottom of the filter screen to the machine from the machine end.
3. Place the tube from the bottom of the filter screen into a suitable container.
4. Backflush the filter screen by pouring flushing fluid through the hose from the "FLUSH RETURN CAP".

TROUBLESHOOTING:

Pump does not turn:
• Check power supply. If power supply is OK, pump may be blocked by debris or seized. Contact the distributor.
Pump turns on then stops:
• There is too much load on the pump motor. There may be debris in the pump or bad seals or bearings. Contact the
distributor.
Pump turns, but there is little or no flushing fluid flow:
• Make sure there is plenty of flushing fluid in the internal tank. Add flushing fluid if necessary.
• The item being flushed may be mostly or totally blocked. Connect the hoses together with a male 1/4" SAE flare union
to "EXTERNAL AIR/N2".
