Install flue pipes in accordance with all local codes.
Operating a machine that is not completely or fully assembled could result in injury or property damage. Do not operate this machine until it is completely assembled. Inspect hoses, fittings, and heat exchanger for leaks or fatigue before each use.
Filling a machine with fuel in an explosive or poorly-ventilated area can cause an explosion. Only fill the fuel tank in an open area. Do not fill the tank near open flames or while the unit is running. Do not smoke while filling the tank. Do not over-fill the tank. Wipe up any spills. Tighten the cap on the tank when finished. Use kerosene, or #1 or #2 diesel as a fuel only.
Do not use K-1 kerosene.
Tampering with the machine's factory preset unloader valve setting and/or the pressure relief valve setting could result in a machine explosion. Do not attempt to change the settings. Discontinue use if a malfunction occurs and contact your local authorized Delco distributor.
DANGER: Operating a pressure washer with a malfunctioning burner or burner controls could result in a machine explosion. Inspect burner and burner control operation before each use. If you suspect a problem with the burner, discontinue use immediately and
contact your local authorized Delco distributor for assistance.
DANGER: Failure to properly maintain the heat exchange coil can result in a steam explosion. Scale or lime buildup will act as an insulation and decrease the efficiency of the heat exchanger coil and will also cause hot spots. This can result in a weakening of the tubing which in turn may cause a rupture.

OPERATING INSTRUCTIONS
Following delivery of your Delco pressure washer, inspect the unit for shipping damage and follow these directions:
1. Locate the unit in a convenient location. Your Delco pressure washer has an overall cleaning range of
80'. Securely fasten the pressure hose connection.
2. Observe all danger, warning, and caution statements.
3. Connect the power cord to an appropriately sized three wire grounded circuit. The circuit chosen should have no other loads present and should be of the shortest possible length to the main circuit panel. Test and reset the GFCI.
4. Connect the water supply and turn it fully on, checking all hose connections for leaks.
Note: Apply pipe sealant or tape at all connections.
5. Connect the high pressure hose to the gun.
6. Connect the extension wand to the gun.
7. Fill fuel tank with kerosene, or #1 or #2 diesel.
8. If your unit is a trigger control, squeeze the trigger. Turn the control switch to position one (cold water wash). Allow air to purge from the system. Check the system for leaks.
9. Point the wand toward the floor. Flush out the system.
10. Turn machine to the "OFF" position.
11. Install nozzle onto the wand.
12. Turn the control switch to position one to establish water flow. Turn control switch to position two (hot water wash). The burner should automatically come on.
WARNING: If water should stop flowing from the gun, turn unit off immediately and contact an authorized Delco service person.
NOTE: On initial start up, or if the unit runs out of fuel during use, there will be a slight hesitation as the fuel system purges air. Only under these circumstances should there be any hesitation present.
After the burner lights there should be no visibly apparent smoke. If your unit is a trigger control, release the trigger. The unloader should activate and the flame should cease on the burner automatically.
13. Point the wand toward the object to be cleaned and proceed.
14. For chemically enhanced cleaning, place the chemical feed line in liquid detergent. Open the metering valve. Dial metering valve to desired chemical concentration. Close metering valve for rinsing.
Page 4
DANGER: The detergent level should never fall below the chemical line. If you should discover this condition, immediately turn the metering valve off. Air introduced into the system will cause pump damage and create steam space if the burner is on which may lead to a steam explosion.
Equalizer Owner's Manual - Belt Drive Models
15. Following the hot water wash, turn the control switch to position one. Allow the unit to run and adequately cool down the heat exchanger. This period of time may be spent on a cold water rinse.
16. Turn the control switch to position zero (off). Disconnect the power cord. Turn the water supply off and disconnect. Disconnect the pressure hose, then drain.
FREEZE-UP PREVENTION
To prevent freeze-up follow these instructions:
1. Drain the float tank.
2. Remove the spray nozzle from the wand.
3. Mix antifreeze concentrate and water in a large container. Read the recommended mixing instructions given with the antifreeze.
4 Fill the float tank with the antifreeze mixture.
5. Put the end of the chemical line in the float tank. Fully open the metering valve.
6. Turn the control switch to position one.
7. Let the pump run until the antifreeze moves through the pump, coils, and pressure hose.
NOTE: The trigger on the gun must be pulled to allow antifreeze to pass through the coils, and then the trigger must be released to allow the antifreeze to pass through the bypass line.
8 Turn the control switch to the “O” position and close the metering valve.
9. Unplug the cord and put the machine in a dry building.
