INLET FILTER (TO WATER PUMP)
The filter inside and on the bottom of the water box
is rubber with a stainless steel screen. This should
be inspected and cleaned on a weekly basis.
Replace, if damaged.
NOTE: Vacuum all excess water and debris from
water box prior to removing strainer.
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
Y–STRAINER (OUTLET)
Inspect the Y-strainer after the first week of running
the unit by unscrewing the screen and removing 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 VALVES
Examine the packing nut on the chemical selector
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
The nitrogen accumulator is pressurized to 250 PSI
and must be replaced periodically. The accumulator
cannot be repaired or recharged. We recommend
replacement every 1000 hours of use.
PRESSURE REGULATOR
Lubricate the o-rings every 100 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.
