WATER PUMP DRIVE BELT
To tighten the water pump belt:
1. Loosen the bolts which hold the water pump
mount to base.
2. Turn the belt tension adjusting bolt until the
proper belt tension is achieved. (1/2" deflection
in the center of the belt, halfway between the
pulleys).
3. While checking the alignment, tighten the bolts
which hold the water pump mount to base.
WATER PUMP CLUTCH
After removing or replacing water pump clutch, make
certain that set screws are tight.
FLOAT VALVE (WATER BOX)
The float valve should only be adjusted if the water
box is overflowing or the water level in the box is
lower than 5-1/2".
1. If the box is overflowing, remove, and check the
float valve for debris or damage.
NOTE: If the float ball has any water inside it
must be replaced.
When replacing float ball, DO NOT over- tighten,
as the rod can puncture the ball. Make sure to
tighten the nuts on the rod.
2. Disassemble the valve and check the piston and
seat for damage, replace if needed. See the
“Illustrated Parts Listing” for a parts break-down.
PRE-FILTER STRAINER
The strainer basket located inside the pre-filter
should be removed and cleaned whenever it is full of
debris. This should be done at the end of each job.
Y-STRAINER (OUTLET)
Inspect the Y-strainer after the first week of running
the unit by unscrewing the screen and remove any
accumulated debris. Inspect the strainer again
every 2 weeks.
The Y-strainer should then be inspected every
month. However, if the Y-strainer has a frequent
build-up of debris it should be inspected and cleaned
more often.
TEMPERATURE BALANCE ORIFICE
Inspect the Temperature Balance Orifice every
week. Be sure to drain the water box below ½ full.
Clean as necessary. The orifice and screen need to
be kept clean. Cleaning in this way will be
dependent on the water hardness you are using.
CHECK VALVE (OUTLET)
Inspect the check valve when rebuilding the
chemical pump or as needed. Remove and
disassemble the check valve. Check the Teflon seat
for debris or abnormal wear. Clean or replace seat if
needed.
NOTE: Improper seating of the check valve poppet,
damaged spring, or o-rings will cause poor operation
of the chemical system.
For the procedure, see the "General Service
Adjustments” section in this manual for details.
CHEMICAL PUMP
Rebuild the chemical pump every 500 hours. This
involves changing the diaphragm and check valves.
For the procedure, see the "Chemical Pump”
section in this manual for details.
NOTE: Inspect chemical filter daily.
