OPERATING THE MACHINE
1. Connect the swivel end of the discharge hose to the cleaning gun.
2. Attach the hose to the machine outlet.
3. Check the fuel level in the fuel tank. Add fuel if required. It is best to keep fuel tank full during nonworking conditions.
4. Attach an ordinary garden hose to the pump/unit inlet. Turn on the water supply and let the water flow trough the unit.
5. Place the end of the soap line into your soap solution container.
On initial start up, or if machine has not been operated for several days, it is advisable to remove the nozzle from the cleaning gun and flush out any foreign material. Open the water supply.
Turn on the engine and let the unit run until clear water flows through the cleaning gun.
1. Turn on the water supply.
2. Add fuel if required. Check oil levels in pump and engine before starting.
3. Install the high pressure
/ tip into the cleaning gun.
4. Securely hold the cleaning gun and start the unit/motor.
5. Press and hold the trigger to start cleaning.
6. The recommended method of cleaning is:
A. Wet entire surface and remove the loose dirt with water only,
B. Turn on the soap by installing the low pressure/soap nozzle (Black). NOTE: The operating pressure of the machine will drop to nearly zero until the soap line is primed.
C. Cover the entire surface to be cleaned with soap/water solution by applying from the bottom up. Allow the soap to stay on surface four to five minutes.
D. Stop the unit, replace the soap nozzle with a high pressure nozzle, re-start the unit and wash at high pressure with water only from the top down.
Soap will flush from the coil and discharge hose within a minute or two of operation.
E. For hot water washing, turn the switch to ON position (burner).
If there is a sudden loss of pressure while washing with hot water, turn the burner off immediately and attempt to locate the problem while running cold water only. Failure to turn the burner off could cause excessive temperature and pressure build-up in the heating coil.
SHUT DOWN INSTRUCTIONS
1. If the burner is on, set the switch to the OFF position
2. Run water through the pump until cool water flows from the cleaning gun. Failure to do this could result in increased coil scaling.
3. Turn the engine control switch to off.
4. Turn off the water supply.
5. If the machine will be exposed to freezing temperatures, see winterizing procedure.
THINGS TO CHECK DAILY
1. Check oil level in pump.
2. Fill fuel tank at the end of each day’s use to prevent condensation build-up in fuel system.
3. Fill soap container.
4. Check oil level in engine.
THINGS TO CHECK WEEKLY
1. Check and clean water float tank (if equiped with float tank) and pump inlet screen.
2. Check all hoses for leaks and damage. Repair or replace as needed.
3. Check pressure nozzle for wear. Replace if needed.
4. Check all nuts and bolts. Tighten as needed (DO NOT OVER TIGHTEN.)
5. Check all water connections for leaks. Tighten if loose.
Manual Page 8
MAINTENANCE OF COMPONENTS
1. Refer to pump section in this manual for your model of equipment.
2. Change pump oil after the first 25 hours of use.
hours or 3 months, whichever comes first.
Subsequent changes should be every 250
A. Motor must be off. Disconnect the power.
B. Remove drain plug on pump and drain oil.
C. If the oil has water in it, it is important to flush out the pump with oil before refilling pump with the proper oil.
3. Refilling: Replace drain plug and fill slowly to the dot in the center of sight glass, or the proper level on dip stick. Do not over fill.
4. Use high quality 30 wt. non-detergent oil.
1. BLOWER FAN: Clean blower fan in burner housing once a year or as often as needed. Dirt and deposits will reduce air delivery and affect combustion.
2. FUEL NOZZLE: Keep tip free of surface deposits wiping with a clean, solvent saturated, cloth rag.
The nozzle should be changed once a year for maximum heating and emission control.
3. FUEL FILTER: Clean or replace every 400 hours or 3 months, whichever comes first (or as needed). This will help prolong fuel pump life and burner efficiency.
4. FUEL TANK: Drain one pint of fuel from bottom of fuel tank every 50 hours of use or every two weeks, whichever comes first. Check for water or contaminates in fuel. If any are present, drain and flush fuel tank then refill with clean fuel. This will prolong fuel pump life and burner efficiency.
5. ELECTRODES: Clean off carbon deposits on electrodes. To adjust electrodes refer to figure and these instructions:
A. TO REMOVE THE GUN ASSEMBLY: Disconnect the oil line at the burner fan housing. Remove gun holding nut on outside of housing. Loosen transformer hold-down screw and swing open transformer on hinges. Gun assembly can now be removed by turning 1/4 turn and lifting out and pulling down through this opening.
B. SPACING OF ELECTRODES: The electrodes should be spaced 1/8 inch apart, 5/16 inch above the top of fuel nozzle and 1/4 inch from the center of fuel nozzle tip, to the electrodes.
6. FUEL PUMP: To bleed air out of fuel pump, open air bleed valve on side of fuel pump. Turn machine and burner ON. When fuel looks clear (NOT FOAMING), close air bleeding valve. Air is out of fuel lines and fuel pump.
A. To check fuel pressure, plumb a 200 PSI gauge into the port marked gauge. DO NOT USE
BLEED VALVE PORT TO CHECK FUEL PUMP PRESSURE.
B. To adjust fuel pressure, insert a small flat screwdriver into pressure regulator slot and turn clockwise to increase pressure and counter clockwise to decrease pressure. One full turn is about
10 PSI. Use a pressure gauge. normal operating pressure is 140 PSI. DO NOT EXCEED 150
C. Service the fuel pump once every 50 hours or 3 months by cleaning the fuel strainer screen.
A clogged strainer or fuel filter will cause fuel pump starvation and dry the fuel pump up.
The ONLY lubrication the fuel pump has is the fuel that runs through it. KEEP IT CLEAN for longer fuel pump life.
1. Shut off and disconnect the water supply.
2. Drain float tank.
3. Install antifreeze kit (available through local dealer.)
4. Remove nozzle from wand, and insert pick up hose and soap line into a bucket of 50% solution of antifreeze. Pump antifreeze through machine. Open and close trigger gun a few times to winterize unloader system. When antifreeze flows from the wand, shut the pump off. Disconnect antifreeze kit.
attempting to wash ANY painted surface, pump anti-freeze out of machine into a clean bucket and save for next use.
Poor grades of fuel oil or inadequate combustion air will cause heavy soot build up on the outside surface of the heating coil. This will insulate the coil and restrict air flow through the coil, further aggravating the soot build up.
To clean off soot, add Red Devil Soot Remover, using manufactures mixing instructions, or remove coil and clean thoroughly, or Call a Factory Authorized DELCO Dealer.
DE-LIMING OR DE-SCALING OF COIL
In hard water areas, or when using the wrong kind of soap, lime build-up inside the coil pipe will occur.
Lime build-up will decrease the water temperature, water flow may eventually plug the coil.
It is recommended that a low pressure auxiliary pump be used if de-liming or de-scaling is needed.
To install low pressure auxiliary pump.
1. Disconnect high pressure hose that goes between high pressure pump and coil inlet.
2. Connect about four feet of hose with screen to suction side of a low pressure auxiliary pump.
3. Connect a discharge hose between the low pressure auxiliary pump discharge side and the inlet.
4. Disconnect high pressure discharge hose from coil outlet.
5. Connect another 5-6 feet of hose to the coil outlet and run to a 5 gallon bucket.
6. Stick low pressure auxiliary pump suction hose w/screen into 5 gallon bucket.
7. Mix 2 gallons of water with 1 container of Coil Doctor.
8. Turn on pump and circulate the acid mixture through the coil system for about 40 minutes or until discharge solution stops foaming.
After cleaning, remove low pressure auxiliary pump assembly and connect all plumbing. Remove pressure tip from end of wand. Turn on pressure washer and run clean water through machine for about 5 minutes. This flushes out the coil and neutralizes any remaining acid. Replace pressure tip.
