Operating instructions

R. WATER OR OIL LEAKING FROM BOTTOM OF PUMP
1. Water – noticeable amounts.
Inlet water seals on pistons failing. See appropriate pump manual.
Cracked pump manifold from freezing – replace.
2. Oil – noticeable amounts.
Leak and failure of oil seals on pistons. Return to Siebrings for repair
(notify to verify condition).
S. SOLUTION INJECTOR FAILURE
1. Improper water supply to pump.
Turn water bypass screw counter clockwise. This will decrease the
solution draw, increasing the water supply to the pump.
2. Improper metering screw adjustment.
Metering screw turns left to increase solution flow. Do not exceed 5 turns
form full closed position. Try to achieve flow of ½” per second for most
thick detergents passing through the plastic solution feed tube.
3. Plugged strainer on solution tank.
Dirty screen in tank filter assembly, or undissolved powdered soap.
4. Water back feeding to solution supply tank through injector.
Dirty, deformed or missing check ball in injector metering assembly.
Weak ball check spring.
Bad washer on ball seat in intake on injector.
T. WATER SUPPLY AND CONTAMINATION
1. Sand from private wells.
Allow water sample to stand in clear glass bottle over night to observe
sediment. Add line filter if in doubt.
2. High sulphur.
Brass parts may need replacement when used in high concentrations of
sulphur.
3. Hard water
On hot washers, if water tests to 90 grains of hardness or above, use of a
water softener is required for improved coil life and prolonging the time
between cleaning and/or de-liming.
