3.10 Operating in Freezing Conditions
Shutdown
1. Allow the vacuum blower to operate for a
couple of minutes after shutting down the high
pressure and charge water pumps to clear
waste water from hoses and dry out blower
system.
2. Make sure the clean water and debris tanks are
drained immediately at the end of each shift.
3. All system hoses and the Hog Head assembly
should be drained of all water and/or filled with
an anti-freeze solution. (Non alcohol)
4. Refer to the UHP pump manufacturer’s proce-
dures for maintaining and operating the pump
in freezing climates.
5. Open the drain valve at the charge water pump
and allow the hoses and pump to completely
drain. With the valve still open, activate the
pump briefly to pump out any remaining water,
about a cupful. Then close the valve.
6. Pour 2 gallons of anti-freeze into the high pres-
sure pump stuffing box sump so it will drain to
the bilge pump sump system. Allow the bilge
pump to run until anti-freeze is visible at the
bilge pump hose fitting in the debris tank.
7. Drain the vacuum canister immediately at the
end of each shift.
8. Remove the blower silencer drain plug and
drain the silencer at the end of each shift.
9. Follow all other instructions in the Warm
Weather Shutdown Procedure.
CAUTION
IF YOU OPERATE IN FREEZING TEMPERATURES OR EVEN
TEMPERATURES BELOW 60 DEGREES FAHRENHEIT (16
DEGREES CELSIUS), IT WILL BE NECESSARY TO OPERATE
THE SYSTEM, INCLUDING ENGAGING THE BLOWER AND
HIGH PRESSURE PUMP, AT IDLE SPEED ONLY UNDER LOAD,
UNTIL HYDRAULIC FLUID HEATS UP ABOVE 60 DEGREES
FAHRENHEIT (160 CELSIUS).
3.11 Operation Routine Maintenance
Some components of the ultra-high pressure water
and vacuum systems require preventative routine
maintenance during a typical water blasting shift.
This maintenance is considered routine and a
component of the water blasting process. The
frequency for maintaining the items listed in this
section will vary, depending on the quality of the
clean water supply, the overall condition of the
water blasting systems and proficiency of the
operators.
A well maintained truck operated by an experi-
enced operator and using water from a very clean
source may only require routine maintenance
at the beginning or end of each shift. A poorly
maintained truck, poor quality clean water sup-
ply, or truck that is not being operated properly
could require routine maintenance several times
during a shift.
The following is a list of the components that
require maintenance during a typical water blast-
ing shift and a brief description of the procedure.
Refer to the Lubrication and General Maintenance
section of this manual for detailed instructions for
maintenance items listed.
The following items typically require main-
tenance during a typical shift:
• 10 Micron Filter - The filter should be replaced
at the start of each shift and may require re-
placement during the shift if low charge water
pressure is indicated. Shutdown the system,
remove the filter clamp and cap, then remove
and replace the filter. Reinstall and tighten
the cap.
• 1 Micron Filter - The filter should be replaced
at the start of each shift and may require re-
placement during the shift if low charge water
pressure is indicated. Shutdown the system,
remove the filter clamp and cap, then remove
and replace the filter. Reinstall and tighten
the cap.
•
Purge Air From The Charge Water System -
If the clean water filters are replaced or the
operator allows the clean water tank to run
dry, air will be introduced into the charge
water system that must be purged before
the system will prime and supply clean water
to the ultra-high pressure pump. Follow the
procedure outlined in the Lubrication and
General Maintenance section.
