TwinForce™ Series Waterblast Unit
Water Inlet
The inlet water connection (Figure 13 ) is a 2”
Camlok Nipple. The inlet regulator is adjust-
able and pressure to the fluid end should not
exceed 75 psi.
Bypass Drain
The bypass drain is connected to the bypass
valve. Water will drain from the hose onto the
ground during pump operation as explained
in “Secondary Filter (40K Units)” on page
11. This hose can be plumbed to an alter-
nate drain or tank for collection if required. If
bypass drain water needs to be routed to a dif-
ferent location, contact Jetstream engineering
for assistance.
Secondary Filter (40K Units)
A secondary filter ( Figure 14) is mounted on
top of the pump for use when operating at
“40K”. The filter is not connected during 15K or
20K operation.
A pressure gauge is mounted on the filter to
monitor pressure in the filter.
A differential pressure switch is mounted
in the filter circuit to monitor proper flow
through the filter. If the filter becomes plugged
and flow is insufficient, the switch will cause
the engine to shut off. “Emergency Stop” will
be displayed on the control panel.
A drain valve is located on the filter cover that
allows the operator to purge air from the filter
at startup.

CAUTION
If a bypass discharge hose is used, the hose
must be properly sized to prevent excessive
backpressure. Excess backpressure can cause
vibration and pulsation in the system leading to
damaged system components.
