Page 6: Personal Safety
PERSONAL SAFETY -Wear safety glasses at all times when working on pumps. -Wear a face shield and proper protective gear when pumping hazardous chemicals. -Keep the work area clean, uncluttered and properly lighted. Secure and stow all unused tools and equipment. -Keep visitors at a safe distance form work area. -
Page 7: General Safety
GENERAL SAFETY A safety pressure relief device is installed at the factory. Removal of this device could void the unit warranty and cause injury to personnel. WARNING – Do not pump flammable or explosive fluids such as gasoline, fuel oil, kerosene, etc. -
Page 8: General Operating Instructions
General Operating Instructions Check Oil Level (See Honda gas engine Owner’s Manual for additional information). Check CAT pump oil level. Oil level must be up to the red center dot (see CAT Service Manual). Connect pressure water supply hose or immerse suction hose in adequate clean water supply. - Page 9 TEMPERATURE CONTROL – 430027 Adjust temperature control to the desired temperature. TEMPERATURE CONTROL COLD Typical Wiring To Flow Switch To Control Switch OPERATION – DEMA INJECTOR 203B / 204B Warning: Use care when handling hazardous chemicals. Warning: Setting the water bypass screw too far in could starve and damage the pump. See figure below for location of water bypass screw and fine metering adjustment screw.

Jumper across red / yellow terminal and check for machine operation. If machine operates normally, replace switch. Remove jumper. Repairs and replacement – Field repairs, except for the replacement of the cover can not be made. Contact Siebring Manufacturing for replacement flow switch. - Page 12 Honeywell Aquastat Controller L4006A Copper Capillary Tube (to sensing bulb) Differential Adjustment Wheel Wire Terminal Screws Set-point Indicating Dial Operation - L4006A breaks the circuit on a temperature rise to the control setting. High limit controller: Shuts off burner when water temperature exceeds high limit setting. Burner restarts when temperature drops to high limit setting.
- Page 13 Pressure Sensitive Regulating Unloader This type of unloader may be referred to as a “Trapped Pressure” type or just "Pressure" type. This type of valve opens to bypass when it senses the pressure build up of the pump output having nowhere to go. The main characteristic of this most commonly used valve is how it traps the pressure in the hose when the trigger of the pressure gun is released and unloading excess pressure between the pump &...
- Page 14 Pressure Sensitive Regulating Unloader Spray Mode Gun trigger is depressed with gun in use. Pump flow enters from the left of the diagram (inlet port), passes through the unloader, out of the outlet port, to the gun. CAUTION: A minimum bypass of 5 - 10% of the UNLOADER RATED FLOW CAPACITY is required for proper unloader performance.
- Page 15 Pressure Sensitive Regulating Unloader Bypass Mode WARNING: DO NOT OPERATE IN BYPASS Gun trigger valve is closed, gun is MODE LONGER THAN not in use. Pump flow enters from 2 MINUTES. the left of the diagram (inlet port), dead ends against output check valve, overcomes the spring pressure holding the piston assembly and is forced down...
- Page 16 Adjustable Pressure Regulating Unloader The following Unloader models are used on Siebring Pressure Washer applications: Cat Pump model 7500, 7534, 7600 & 7672. J.E. Adams Golden Eagle model 7100. Operation – The unloader holds established system pressure in the discharge line when the trigger gun is closed, solenoid valve is closed (gate) valve is closed or the nozzle is clogged, bypassing the unrequired flow between the pump and the unloader.

TROUBLESHOOTING (CONTINUED) UNLOADER CYCLES RAPIDLY Rapid in-out movement of unloader plunger (units without complete shutoff). Leak in high pressure line, gun leak, or a “weep” type gun is in use. Defective poppet (nylon plunger in in lower portion of unloader). Poppet may be deformed or sticking. - Page 26 TROUBLESHOOTING (CONTINUED) PUMP MOTOR FAILS TO STOP Flow switch on “complete shut-off units” plunger sticks. Free the magnetic plunger within the flow switch. Remove plunger and coat with Vaseline. Check for ½” non-metallic spacer in place between mounting area and switch body (see page 8 for more info.). Air in coil or air in piping of facility.

TROUBLESHOOTING (CONTINUED) BURNER MOTOR FAILS TO START Check burner switch on side of burner. Up is “on” may be defective Water temperature control stuck “open.” Jumper wire terminals on temp switch momentarily. If burner starts, replace temperature switch. Defective flow switch. Jumper wire terminals on flow switch momentarily. -

TROUBLESHOOTING (CONTINUED) INTERMITTENT FLAME Dirty oil supply, water in fuel tank. Check filter and nozzle for cleanliness. Clear tank and filter of water. Low oil supply Raise fuel level in supply tank. Oil line cracks and/or loose connections. Tighten or replace parts to prevent air bubbles (suction leaks) in oil line. WATER LEAKING FROM HEATING COIL COMPARTMENT Drips Condensation drips (several per minute) are normal. -
Page 29: Troubleshooting Continued
TROUBLESHOOTING (CONTINUED) WATER OR OIL LEAKING FROM BOTTOM OF PUMP Water – noticeable amounts. Inlet water seals on pistons failing. See appropriate pump manual. Cracked pump manifold from freezing – replace. Oil – noticeable amounts. Leak and failure of oil seals on pistons. Return to Siebrings for repair (notify to verify condition). - Page 30 DELIMING INSTRUCTIONS FOR HOT WATER COIL CAUTION: Do not use this procedure on a coil that is completely plugged. For severe cases, call Siebring Manufacturing. Disconnect the steam hose at the unit. In a plastic container, put 2 ½ gallons of water and into this very slowly add one gallon of muriatic acid.
