TwinForce™ Series Waterblast Unit

Filter Cartridge Replacement

1. Relieve pressure from the housing using

the bleed valve then loosen the three eye-

nuts (Figure 55

) on the filter cover.

2. Slowly open the cover and capture the

spring (Figure 56) and spring keeper.

Remove the filter cartridge.

Install the new filter cartridge onto the

guide rod. Ensure the guide rod is correct-

ly seated into the bottom of the housing.

5. Inspect the O-ring and install a new one if

necessary.

6. Place the spring keeper and spring into

place on the end of the filter cartridge.

Move the filter cover into position and

tighten the eye-nuts.

8. Prepare the pump for operation and start

the unit. Start a typical blast operation

and record the following:

• Engine rpm
•

Gauge pressure on the secondary filter

9. Save this record for monitoring the status

of the secondary filter. Monitor the pres

sure gauge as more hours of operation

are accumulated on the filter cartridge.

When the pressure on the filter gauge has

dropped approximately 7 to 10 psi (0.48 to

0.69 bar) (with the unit operating at the

same rpm as earlier recorded), the filter

must be replaced.

Switch Adjustment

The differential pressure switch will shut

down the unit when the pressure drop across

the filter is approximately 7 to 10 psi (0.48 to

0.69 bar). If the switch doesn’t close within the

7 to 10 psi (0.48 to 0.69 bar) range, it may need

to be adjusted. Contact Jetstream for switch

adjustment instructions.

Uni-Valve Life

The uni-valve seats can be damaged by dirty

water. It is important to change filters regular

ly to improve pump performance and prolong

valve life. (Nozzles and bypass cartridges are

also adversely affected by dirty water).
