WASTE TANK STRAINER BASKET
The strainer basket located inside the waste tank
should be removed and cleaned whenever it is full of
debris. This should be done on at least a daily basis.
BYPASS MANIFOLD
(STRAINER AND JET BLOCK)
Check the strainer and the jet weekly. Remove any
debris or blockage.
For the procedure, see the "General Service
Adjustments” section in this manual for details.
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 at 2
and 4 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.
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 1000 hours. This
involves changing the diaphragm and check valves.
For the procedure, see the "General Service
Adjustments” section in this manual for details.
CHEMICAL AND
HEAT BYPASS VALVES
Examine the packing nut on the chemical selector
valve, heat bypass valve, and chemical metering
valve every 200 hours. Keeping these valve
packings properly adjusted will eliminate possible
leakage from the valve stems and add to overall
valve life.
For the procedure, see the "General Service
Adjustments” section in this manual for details.
NITROGEN ACCUMULATOR
Check the nitrogen pre-charge at least once a year.
Recharge the accumulator and replace the bladder,
when needed. This should be performed by an
Authorized Service Center.
Recharge accumulator with nitrogen ONLY. DO
NOT charge accumulator over 250 PSI.
PRESSURE REGULATOR
Lubricate the o-rings every 50 hours. Use o-ring
lubricant Part #05-008035.
For the procedure, see the "General Service
Adjustments” section in this manual for details.
VACUUM HOSES
To assure maximum hose life, we recommend that
the hoses be washed out with clean water at the end
of each working day.
CATALYTIC AIR PUMP
Check and/or replace the air pump every 1500
hours. When replacing, it will also be necessary to
replace the air pump pulley.
TEMPERATURE SOLENOID
Remove hard water deposits from the temperature
solenoid every 200 hours or as often as required.
For the procedure, see the “General Service
Adjustments” section in this manual.
