preVentiVe maintenance:
leaKs:
Promptly eliminate any leaks found in the pumping system by
removing suspect parts, applying thread sealant to the threads and
reinstalling.
NOTE: If using teflon tape, be certain no tape gets inside any plumbing to
prevent the possibility of a plugged spray nozzle.
QuicK cOuplers:
There are o-ring seals inside the couplers which will
deteriorate. To replace, simply install a replacement o-ring to correct
the leak. (Additional o-rings can be purchased from your dealer.)
nOZZle:
Water flow through the spray nozzle will erode the orifice,
making it larger, resulting in a pressure loss. Nozzles should be
replaced whenever pressure is less than 85% of the maximum. The
frequency of replacement will depend upon such variables as mineral
content in the water and number of hours the nozzle is used.

WinteriZing:
For storage and transportation purposes in subfreezing ambient temperatures,
it will be necessary to winterize this unit. This unit must be protected to the
lowest incurred temperature for the following reasons:
. If any part of the water handling system becomes frozen;
excessive pressure may build up in the unit which could cause the
unit to burst resulting in possible serious injury to the operator or
bystanders.
2. The water handling system in this unit may be permanently
damaged if frozen. FREEZE DAMAGE IS NOT COVERED BY
WARRANTY.
If you must store your unit in an area where the temperature may fall below
32°F, you can protect your unit by following the procedure outlined below.
AIR BLOW OUT:
. Remove the nozzle from the wand assembly. Squeeze the trigger
until water ceases to exit the wand assembly.
2. Connect an air fitting from an air hose to the heater module inlet.
3. Run compressed air into the system to remove all water from the
system.
