HOW TO PREPARE THE MACHINE FOR OPERATION
NOTE: Following delivery of your Delco pressure washer, inspect the unit for shipping damage.
Assembly:
1. Uncrate machine. Remove cleaner, parts package, gun and hose from shipping carton.
2. Assemble cleaner, gun, and hose. Do not install the pressure nozzle at this time.
3. Install the draft divertor.
4. Refer to the machine drawing in the service section for specific locations of parts you assemble.
Installation:
1. Do not install the machine in small confined areas, near exhaust fans or in a wash bay where the unit
could be subjected to overspray and cleaning chemicals. Install only in well ventilated areas where
adequate flow of air is available. Adequate oxygen is needed for combustion or dangerous carbon
monoxide will result. Stationary units should be installed in accordance with local plumbing and electrical codes.
2. In all installations, this machine must be vented to the outside with a draft divertor and rain protection.
3. This machine is designed to be installed indoors and must be protected from direct spray or overspray of
water.
WARNING: Adequate oxygen is needed for proper combustion or dangerous carbon monoxide can
result.
Gas Fired Units:
Natural gas units operate on 3½" of water column pressure at the solenoid valve, and it must have from 7"
to 8" water column pressure supplied to the unit at the inlet. The water column check points are as follows:
Check the 3½" water column pressure from the plug on the bottom of the solenoid valve with the burner
operating. The water column pressure is checked with a manometer. A gas shut-off valve should be installed on the gas line, with a union between the shut-off and the unit. Also a sediment trap should be
installed after the shut-off valve.
Standard butane or propane gas fired units operate on 11" W.C. Use a gas Manometer when checking gas
pressure or when making adjustments to the regulator. Do not use less than 1/2" I.D. hose or pipe in making the gas connection. For top efficiency, a 100 lb. or larger gas bottle should be used.
Minimum gas line iron pipe size required for gas supply per length of gas line from the meter (Natural Gas).
(Based on a pressure drop of 0.3" water column pressure and 0.6 specific gravity.)
NOTE: Do not use flexible gas lines. Check total BTU consumption of facility to be assured of proper
gas supply to operate pressure washer.

Page 8 3000-4, 2000-5 NG/LP
Stacking the Unit:
If the cleaner is used in an enclosed area be sure there is plenty of ventilation.. Be sure the chimney is the
same size as the stack on the cleaner. Poor draft will cause the unit to soot and not operate efficiently.
When placing the unit for installation, keep in mind that the unit should be positioned in such a manner that
the stack will be as straight as possible and protrude through the roof of the building at a proper location and
at sufficient height to eliminate downdraft.
A gas fired unit should have a draft divertor and proper rain protection on the vent pipe.
DANGER: All gas burner equipped cleaners should be installed and serviced in accordance with the
requirements of your local gas company and all applicable state laws or local ordinances.
Water Supply:
1. Connect the machine to the water supply with 3/4" water hose and 3/4" connections.
2. Insure that the water supply is capable of supplying sufficient water flow volume.
CAUTION: Insufficient water flow can cause pump damage and failure.
Gas Supply:
1. Insure that the gas cock knob is in the "Off" position.
2. Installation of gas service to this machine is to be made with 1" plumbing or larger. Refer to chart on
page 4.
Electrical:
CAUTION: This machine must be electrically grounded.
1. Connect only to grounded outlets with 30 ampere, 230 volt a/c (alternating current), 60 Hz, 1 phase
circuits protected by fuses or circuit breakers and GFCI protection.
INSTALLATION CHECKOUT:
Before Starting:
1. Connect discharge hose and gun. Remove pressure nozzle.
2. Connect the water supply hose to the water inlet. Turn the water on and allow the water float tank to fill.
When the tank has filled and the flow through the float valve has stopped, check to insure that there is at
least 1" between the water level and the float valve opening.
3. Before connecting the power supply be sure that the control switch is in the "Off" position.
3000-4, 2000-5 NG/LP Page 9
WARNING: For your safety, if you smell gas:
1. Open windows.
2. Do not touch electrical switches.
3. Extinguish any open flame.
4. Immediately evacuate premises and call your gas supplier.
Pilot Lighting Procedure:
1. Turn control switch to #2 burner position.
2. When the trigger is pulled and water starts being pulled into the pump, the vac switch closes. In a
couple of seconds the pilot valve opens and simultaneously the spark starts. This operation will continue
for 15 seconds or until the pilot ignites. If the pilot fails to light in 15 seconds, the ignition system "locks
out" and the power must be turned off to reset the ignition system.
3. The pilot is ignited, the electronic flame sensing proves the ignition source and turns on the second
valve allowing main gas to flow. (If pilot ignition does not occur within 60 seconds, the system will lockout and turn off power to gas circuit.)
4. The proved pilot ignites the main burner. (Pilot operation continues until burner is shut off.)
5. The spark continues several seconds after the burner is lit to provide stable ignition.
Test for Gas Leaks:
WARNING: DO NOT OMIT THIS TEST. With the main burner in operation, paint the pipe joints, pilot
gas tubing connections, and valve gasket lines with rich soap and water solution. Bubbles
indicate gas leakage. To stop leak, tighten the joints and screws or replace the gasket.
Failure to do this test procedure could cause serious injury.
Manual Shut Down of Burner:
Complete shutdown can be accompished by turning the cock knob to the "Off" position.
INSTALLATION & SERVICING INSTRUCTIONS
WARNING: To avoid possible injury, fire, and explosion, please read and follow these precautions
and all instructions on this machine. Maintenance and repairs performed by unauthorized
personnel could result in damage or injury. Servicing of this unit must always be referred
to an authorized Delco distributor. Repairs, adjustments, and servicing should be limited
to the operations listed below.
1. Installation and servicing of gas appliances and ignition systems must only be performed by qualified
personnel.
2. Turn off gas and electricity before starting installation or service. Turn back on after completion.
3. Caution must be taken to ensure that no raw gas is present in the surrounding area before attempting to
put the machine into operation.
Page 10 3000-4, 2000-5 NG/LP
WARNING: For your safety, if you smell gas: (A) turn off gas at line valve or meter, (B) open windows,
(C) do not touch electrical switches, (D) extinguish all open flames, (E) immediately call
your gas supplier.
4. When using L.P.gas, the Control must be equipped with a regulator. Make sure that no gas is present in
the area before putting machine in operation. L.P. gas is heavier than air. Sniff at floor level for presence of gas. If present do not attempt to start the machine. (See Warning on page 8.) When changing
from natural gas to L.P., or L.P. to Natural Gas using a convertible control, the burner orifice and pilot
orifice must also be changed.
5. Make certain that the pilot orifice being used is the correct size for the gas used.
6. To install or remove control, use a special body wrench on inlet boss. Do not grip body with pipe wrench
or vise.
7. Insert only correct size pipe or tubing into inlet or outlets of control. Insertion of any other objects can
cause internal damage resulting in a hazardous condition.
8. Make sure gas piping is pressure tested before control is connected. High pressure can damage control
causing a hazardous condition. Do not subject control to more than 1/2 P.S.I., (14" W.C.) inlet pressure.
9. Use only new, unused, and correct model controls as replacements. Do not re-use old controls.
10. Make sure piping is clean and free from burrs. Apply a small amount of good quality pipe thread compound suitable for the gas being used. Thread compound should be used sparingly on male threads
only, leaving the first two threads clean. NOTE: Blow lines out with compressed air to remove all dirt or
debris.
11. A drip leg (dirt trap) must be installed, after the shut-off valve, in the gas supply line to the control to
prevent dirt from entering control. See Figure #1. All piping must conform to local codes and ordinances and with National Gas code (ANSI Z223.1 and NFPA No. 54).
12. After installation has been completed, leak test all gas connections with soap solution with the main
burner on. Bubbles indicate leaks that must be corrected.
13. If control has been exposed to water in any way, it must be replaced.
14. Keep combustible material away from gas machine. Keep burner area clean and free of dust and lint.
15. If gas valve fails to shut off, do not turn off electrical power. Turn off gas supply allowing water pump to
continue running until system has cooled. Replace control.

WARNING: If the water should stop flowing from the gun, turn the unit off immediately and contact an
authorized Delco service person.
7. Point the wand toward the object to be cleaned and proceed.
8. For chemically enhanced cleaning, place the chemical feed line in liquid detergent. Open the metering
valve. Dial the metering valve to obtain the desired chemical concentration. Close the metering valve
for rinsing.
DANGER: The detergent level should never fall below the chemical line strainer. 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.
3000-4, 2000-5 NG/LP Page 13
CAUTION: To prevent damage to your new cleaner:
1. Do not pump acids.
2. Do not allow the pump to run dry.
3. Do not fail to winterize.
9. 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 maybe spent on a cold water rinse.
10. Turn the control switch to position zero "OFF". Turn the water supply off and disconnect. Disconnect the
pressure hose, then drain.
MAINTENANCE
1. Use a water softener on your water system if it is known to be high in mineral content.
2. Use only high quality Delco chemicals and follow the manufacturer's mixing instructions.
3. The cleaner should be flushed thoroughly after using the chemical solutions.
4. Follow the fuel specifications as outlined in the machine specifications.
5. Clean the strainer screen, in the hose connection at the float tank, periodically.
6. Pump lubricant: Periodically check the oil level. Change the oil after 50 hours of operation, and then
after every 500 hours. Use SAE 30 weight non detergent oil.
7. Use teflon tape or approved sealer on the plumbing connections when reassembling to prevent leakage.
CAUTION: If the machine is to be out of service for a long period of time, we recommend that the
system be flushed out with anti-freeze water solution. Do not run the pump dry for extended periods of time or severe damage will occur.
8. Deliming coils: Periodic flushing of the coils is recommended to extend coil life and prevent lime build
up. See note on page 11.
How To Check The Oil
It is critical that the oil in your pump be checked regularly. To check the oil follow this procedure:
1. Locate the oil dipstick in the plug on the top of the pump.
2. Turn the oil plug counterclockwise.
3. Wipe the dipstick with a clean cloth.
4. Screw the dipstick in. Pull it back out and check for the oil level mark. The oil level should be at the top
mark.
5. If the oil is below the notch, add SAE 30 weight, non-detergent oil.
6. Put the dipstick back into the hole.
7. Turn the plug clockwise until it stops.
Page 14 3000-4, 2000-5 NG/LP
NOTE: Change the oil after the first 50 hours of use and then after every 500 hours of use. SAE 30
weight oil must be used.
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.
How to Check/Clean the Heat Exchange Coil:
The heat exchange coil should be inspected for deposit build-up after 40 hours of use, or once a month,
whichever comes first. In hard water areas a water softening system should be employed.
Scaling or liming of the coils is caused by mineral deposits from the water and occurs much faster in hardwater areas and with heavier machine usage. Lime build-up can also be caused by inferior cleaning compounds.
DANGER: Failure to properly maintain the heat exchange coil can result in a steam explosion! Scale
or lime build-up 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
can lead to a steam explosion.
