The Surface Cleaner Unit high pressure swivel will “weep” wa-
ter from underneath the cover. This weeping is normal for this
swivel. The swivel uses water to lubricate its floa ng seal face
to keep wear down to a minimum.
Also, the high pressure swivel is equipped with a grease fi>ng
and should be greased at least
once every three months
. A
good quality ball bearing grease is recommended.
DO NOT
OVER GREASE THE BEARING!

The thermal relief valve protects the pump from damaging
heat build-up while the unit is in bypass mode. Sensing a rise
in temperature, the valve opens and discharges a small
amount of heated fluid. This allows cooler water to enter the
system and cool the pump. When the unit starts cleaning
mode the cooler water entering the pump will cause the valve
to close immediately.
