Maintenance
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 Adjust-
ments" section in this manual for details.
Chemical Pump
Rebuild the chemical pump every 500 hours. This
involves changing the diaphragm, plastic disk, and
check valves.
For the procedure, see the "General Service Adjust-
ments" section in this manual for details.
NOTE: Inspect chemical inlet tube strainer daily.
Chemical Metering Valve
Examine the packing nut on the chemical metering
valve every 200 hours. Keeping the valve packing
properly adjusted will eliminate possible leakage from
the valve stem and add to overall valve life.
For the procedure, see the "General Service Adjust-
ments" section in this manual for details.
Pressure Regulator
Lubricate the o-rings every 50 hours. Use o-ring
lubricant Part #86265430.
For the procedure, see the "General Service Adjust-
ments" 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.
High Pressure Solution Hoses
Inspect your high pressure solution hoses for wear after
the first 100 hours of use. Inspect every 25 hours there-
after. If hoses show any signs of damage or impending
rupture, replace the hose.
DO NOT attempt to repair high pressure solution
hoses! Repairing high pressure solution hoses may
result in severe burns and serious injury!
All high pressure solution hoses must be rated for 3000
PSI at 250°F. Thermoplastic hoses do not meet these
specifications and should not be used. Severe burns
and injury may result if the hoses do not meet these
requirements.
Optional Waste Pump-Out
At the end of each work day, make certain that you
remove any debris or sediment which may be inside the
waste pump by pumping fresh water through the pump.
Temperature Balance Orifice
Weekly maintenance of the temperature balance orifice
is required for proper machine operation.
1. Drain water box below half full.
2. Unscrew nozzle cap from the connector body.
3. Remove the adapter, orifice plate, and strainer.
4. Clean any debris from the strainer and orifice plate.
5. Reassemble as shown in Parts Section - Solution
Outlet.
