NOTICE:
THE CHARGE PRESSURE SAFETY SWITCH DEACTIVATES
THE DUMP VALVE WHEN CHARGE PRESSURE DROPS
BELOW 30 PSI (2 BAR) TO PROTECT THE UHP PUMP. IF
WATER FREEZES IN THE PRESSURE SWITCH HOSE, IT WILL
SENSE LOW CHARGE PRESSURE AND PREVENT THE DUMP
VALVE FROM ACTIVATING.
22. Pour 2 gallons 50/50 antifreeze mixture into
the high pressure pump stuffing box sump so
it will drain to the bilge pump sump system.
Allow the bilge pump to run until antifreeze
flows from the bilge pump hose fitting in the
wastewater bladder for several seconds.
23.
Thoroughly clean the vacuum filter canister
and the filter.

into the wastewater bladder. Open the waste-
water bladder drain valve until antifreeze flows
from the valve. Then close the valve.
25. Make sure the debris tank is lowered to the
full down position. Close the door and inflate
the seal.
26. Pour 10 gallons of 50/50 antifreeze mixture
into the debris tank. Activate the wastewater
transfer pump until antifreeze flows from the
hose fitting in the wastewater bladder for 20
or 30 seconds. Then turn off the pump.
27. Open the debris tank gravity drain valve until
antifreeze flows from the valve. Then close the
valve.
28. Shutdown the waterblasting system (Section
3.4) and truck engine.
29.
Turn off the PTO switch and all other control
panel switches.
30. When winterizing the Ultra-High Pressure

dures for additional instructions for operating
and maintaining UHP pumps and equipment
in freezing climates.
