COMPONENT IDENTIFICATION

INSTALLATION

Place machine in a convenient location providing ample support, drainage and room for maintenance.
Remove bolts from pallet to foot bracket. Install rubber feet provided as shown on page 16.
Location:
The location should protect the machine from damaging environmental conditions, such as; wind, rain, and freezing.

This machine should be run on a level surface where it is not readily inﬂuenced by outside sources such as strong winds, freezing temperatures, rain, etc. It should be located to allow accessibility for reﬁlling of fuel, adjustments and maintenance. Nor-mal precautions should be taken by the operator of the machine to prevent moisture from reaching the electrical controls.
It is recommended that a partition be made be-tween the wash area and the machine to prevent water spray from coming in contact with the ma-chine. Excess moisture reaching any electric components or electrical controls will reduce machine life and may cause electrical shorts.
During installation of the machine, beware of poorly ventilated locations or areas where exhaust fans may cause an insufﬁcient supply of oxygen. Sufﬁcient combustion can only be obtained when there is a sufﬁcient supply of oxygen available for the amount of fuel being burned. If it is necessary to install a machine in a poorly ventilated area, outside fresh air may have to be piped to the burner and a fan installed to bring air into the machine.

Electrical:
This machine, when installed, must be electrically grounded in accordance to local codes. Check for proper power supply using a volt meter.

Placement:
Do not locate near any combustible material. Keep all ﬂammable material at least 20 feet away.
Allow enough space for servicing the machine.
Local code will require certain distances from ﬂoor and walls. (Two feet away from walls should be ad-equate.)

Water Source:
The water source for the pressure washer should be supplied by a minimum 5/8″ I.D. garden hose with a city water pressure of not less than 30 PSI. If the water supply is inadequate, or if the garden hose is kinked, the attached pressure washer will run very rough and the burner will not ﬁ re.

Connection:
See Component Identiﬁ cation.

Venting:
Adding exhaust vent pipe to your oil ﬁ red burner is not recommended because restricted air ﬂ ow causes carbon build-up, which affects the operation, and in-creases maintenance on the coil. If a stack must be used, refrain from using 90° bends. If the pipe can not go straight up then use only 45° bends and go to the next size pipe. The overall pipe length must not exceed 6 feet in length. The burner air adjustment must be performed after vent pipe is installed. Use a smoke tester for proper air setting.

OPERATING INSTRUCTIONS

STEP 1: Check fuel tank and pump oil levels on both machines and connect garden hose to pressure washer. CAUTION: Only use fresh water to this machine.
STEP 2: Attach high pressure hose between pressure washer and ma-chine. Turn garden hose water on. Additional adapters and couplers may be needed to connect your brand of pressure washer to the machine.
STEP 4: Connect the power cord into the proper electrical outlet, then push in the GFCI reset button. Start up attached pressure washer according to the manufacturers instructions. When a steady stream of water ﬂ ows from the spray gun and wand the machine is ready for cold water cleaning.
STEP 4: For hot water washing, turn the machine burner switch to the ON position. Adjust thermostat to desired temperature setting. (The burner will light automatically.)

DETERGENTS AND GENERAL OPERATING TECHNIQUES

WARNING: Some detergents may be harmful if inhaled or ingested, causing severe nausea, fainting or poisoning. The harmful elements may cause property damage or severe injury.

STEP 1: Use detergent designed speciﬁcally for pressure washers. Household detergents could dam-age the pump. Prepare detergent solution as required by the manufacturer. Fill a container with pressure washer detergent. Place the ﬁlter end of detergent suction tube into the detergent container.
STEP 2: With the motor running, pull trigger to operate machine. Liquid detergent is drawn into the machine and mixed with water. Apply detergent to work area. Do not allow detergent to dry on surface.
IMPORTANT: You must ﬂush the detergent injection system after each use by placing the suction tube into a bucket of clean water, then run the pressure washer in low pressure for 1-2 minutes.

CLEANING TIPS

Pre-rinse cleaning surface with fresh water. Place detergent suction tube directly into cleaning solution and apply to surface at low pressure (for best results, limit your work area to sections approximately 6 feet square and always apply detergent from bottom to top). Allow detergent to remain on surface 1-3 minutes. Do not allow detergent to dry on surface. If surface appears to be drying, simply wet down surface with fresh water. If needed, use brush to remove stubborn dirt. Rinse at high pressure from top to bottom in an even sweeping motion keeping the spray nozzle approximately 1 foot from cleaning surface. Use overlapping strokes as you clean and rinse any surface. For best surface cleaning action spray at a slight angle.
Recommendations:

• Before cleaning any surface, an inconspicuous area should be cleaned to test spray pattern and distance for maximum cleaning results.
• If painted surfaces are peeling or chipping, use extreme caution as pressure washer may remove the loose paint from the surface.
• Keep the spray nozzle a safe distance from the surface you plan to clean. High pressure wash a small area, then check the surface for dam-age. If no damage is found, continue to pressure washing.
CAUTION – Never use:
• Bleach, chlorine and other corrosive chemicals
• Liquids containing solvents (i.e., paint thinner, gasoline, oils)
• Tri-sodium phosphate products
• Ammonia products
• Acid-based products

These chemicals will harm the machine and will dam-age the surface being cleaned.

RINSING

It will take a few seconds for the detergent to clear. Apply safety latch to spray gun. Remove black soap nozzle from the quick coupler. Select and install the desired high pressure nozzle.
NOTE: You can also stop detergent from ﬂ owing by simply removing detergent siphon tube from bottle.

SHUTTING DOWN AND CLEAN-UP

STEP 1: If using an optional detergent injector, place the detergent line in a bucket of water allowing detergent to be ﬂushed from system.
STEP 2: Turn burner switch off and continue spraying water, allowing the water to cool. After water has cooled to less than 100°F, turn the attached pressure washer off.
STEP 3: Turn garden hose water off. Open the spray gun to relieve remaining pressure.

STORAGE

CAUTION: Always store your pressure washer in a location where the temperature will not fall below 32°F (0°C). The pump in this machine is susceptible to permanent damage if frozen. FREEZE DAMAGE IS NOT COVERED BY WARRANTY.

Stop the pressure washer, squeeze spray gun trigger to release pressure.
Detach water supply hose and high pressure hose.
Turn on the machine for a few seconds, until remaining water exits. Turn engine off immediately.
Drain the gas and oil from the engine.
Do not allow high pressure hose to become kinked.
Store the machine and accessories in a room which does not reach freezing temperatures.

CAUTION: Failure to follow the above directions will result in damage to your pressure washer.
When the pressure washer is not being operated or is being stored for more than one month, follow these instructions:

Replenish engine oil to upper level.
Drain gasoline from fuel tank, fuel line, fuel valve and carburetor.
Pour about one teaspoon of engine oil through the spark plug hole, pull the starter grip several times and replace the plug. Then pull the starter grip slowly until you feel increased pressure which indicates the piston is on its compression stroke and leave it in that position. This closes both the intake and exhaust valves to prevent rusting of cylinder.
Cover the pressure washer and store in a clean, dry place that is well ventilated away from open ﬂ ame or sparks. NOTE: The use of a fuel additive, such as STA-BIL®, or an equivalent, will minimize the formulation of fuel deposits during shortage. Such additives may be added to the gasoline in the fuel tank of the engine, or to the gasoline in a storage container.

After Extended Storage
CAUTION: Prior to restarting, thaw out any possible ice from pressure washer hoses, spray gun or wand.

Engine Maintenance
During the winter months, rare atmospheric conditions may develop which will cause an icing condition in the carburetor. If this develops, the engine may run rough, lose power and may stall. This temporary condition can be overcome by deﬂecting some of the hot air from the engine over the carburetor area.
NOTE: Refer to the engine manufacturer’s manual for service and maintenance of the engine.

PREVENTATIVE MAINTENANCE

MAINTENANCE SCHEDULE

Use clean fuel – kerosene, No. 1 home heating fuel or diesel. Clean or replace fuel ﬁlter every 100 hours of operation. Avoid water contaminated fuel as it will seize up the fuel pump. De-soot coils monthly. Use an additive if diesel is being used.
Check to see that the attached pressure washer water pump is properly lubricated.
Follow winterizing instructions to prevent freeze damage to pump and coils.
Always neutralize and ﬂush detergent from system after use.
If water is known to be high in mineral content, use a water softener on your water system, or de-scale as needed.
Do not allow acidic, caustic or abrasive ﬂuids to be pumped through system.
Always use high grade quality cleaning products.
Never run attached pressure washer pump dry for extended periods of time.
If machine is operated with smoky or eye burning exhaust, coils will soot up, not letting water reach maximum operating temperature. (See section on Maintenance and Service).
Never allow water to be sprayed on or near the motor or burner assembly or any electrical component.
Delime coils as per instructions.

It is advisable, periodically, to visually inspect the burner. Check air inlet to make sure it is not clogged or blocked. Wipe off any oil spills and keep equipment clean and dry.
The areas around the machine should be kept clean and free of combustible materials, gasoline and other ﬂ ammable vapors and liquids.
The ﬂ ow of ventilating air to the burner must not be blocked or obstructed in any manner.

**MAINTENANCE AND SERVICE

**

Winterizing Procedure:
Damage due to freezing is not covered by warranty. Adhere to the following cold weather procedures when-ever the washer must be stored or operated outdoors under freezing conditions.
During winter months, when temperatures drop below 32°F, protecting your machine against freezing is necessary. Store the machine in a heated room. If this is not possible use compressed air on the short hose end. By injecting compressed air, all water will be blown out of the system. Run anti-freeze through the system.

Pressure Relief Valve:
Each machine is equipped with a relief valve to relieve pressure in the system when higher than normal operating pressures are encountered or if the unloader valve should fail. Unusually high pressures come from an object plugging the spray nozzle. If operating pressure is found to be normal and the relief valve continues to leak, repair or replace valve. The Safety Relief Valve should be opened to release any sediment yearly. Start the pressure washer and use an Allen wrench to turn the pressure relief valve counter clockwise until water is pouring out the valve. Then turn the adjustment nut/bolt until the valve stops leaking. Open and close the trigger gun and if water squirts out the valve when you close the trigger gun turn clockwise one full turn until there is no leaking when the trigger gun is closed.

Adjustable Thermostat:
The adjustable thermostat can be set between 100°F to 225°F (37.8° to 108°C). The temperature is dependent on water ﬂ ow and ambient water temperature.

Cleaning of Coils:
In alkaline water areas, lime deposits can accumulate rapidly inside the coil pipes. This growth is increased by the extreme heat build up in the coil. The best prevention for liming conditions is to use high quality cleaning detergents. In areas where alkaline water is an extreme problem, periodic use of Deliming Powder will remove lime and other deposits before coil becomes plugged.
Deliming Coils With A Pressure Washer:
Periodic ﬂushing of coils or optional ﬂ oat tank is recommended.

Step 1 Fill a 5 gallon bucket with 4 gallons of water, then add 1 lb. of deliming powder. Mix thoroughly.
Step 2 Remove the high pressure nozzle from the pressure wand and put the wand into the bucket. Secure the trigger on the spray gun in the open position.
Step 3 Attach a short section (3-5 ft.) of garden hose to the attached pressure washer to siphon solution from the elevated bucket. Start up pres-sure washer, allowing solution to be pumped through pressure washer and into the coils and back into the bucket. Solution should be allowed to circulate 2-4 hours.
Step 4 After circulating solution ﬂush entire system with fresh water.

Removal of Soot In Heating Coil:
In the heating process fuel residue, in the form of soot deposits, may develop between the heating coil pipes and block air ﬂ ow which affects burner combustion. When soot has been detected on visual observation, the soot on the coil must be cleaned off.
Fuel:
Use clean fuel oil that is not contaminated with water and debris. Replace fuel ﬁlter and drain tank every 100 hours of operation. Use Kerosene No. 1 or No. 2 Heating Fuel (ASTM D306) or diesel only. NEVER use gasoline in your burner tank. Gasoline is more combustible than fuel oil and could result in a serious explosion. NEVER use crankcase or waste oil in your burner. Fuel machine malfunction could result from contamination.

Ignition Circuit:
Periodically inspect wires, spring contact and electrodes for condition, security and proper spacing. (CAUTION: 10,000 VOLTS)
Electrode Setting:
(See illustration below)
Electrodes Check : Periodically check wiring connections.
If necessary to adjust electrodes, use diagram.
Burner Nozzle:
Keep the tip free of surface deposits by wiping it with a clean, solvent- saturated cloth, being careful not to plug or enlarge the nozzle. For maximum efﬁciency, replace the nozzle each season. Select nozzle size based on the pressure washer you will be using

Fuel Control System:
The machine utilizes a fuel solenoid valve located on the fuel pump to control the ﬂ ow of fuel to the combustion chamber. This solenoid, which is normally closed, is activated by a ﬂ ow switch when water is ﬂ owing through it. When an operator releases the trigger on the spray gun, the ﬂ ow of water through the ﬂ ow switch stops, turning off the current to the fuel solenoid. The solenoid then closes, shutting off the supply of fuel to the combustion chamber. Controlling the ﬂ ow of fuel in this way gives an instantaneous burn or no burn situation, thereby eliminating high and low water temperatures, and combustion smoke normally associated with machines incorporating a spray gun. Periodic inspection is recommended to insure that the fuel solenoid valve functions properly. This can be done by operating the machine and checking to see that when the trigger on the spray gun is in the off position, the burner is not ﬁ ring.
Fuel Pressure Adjustment:
To adjust fuel pressure, turn the adjusting screw with a 5/32″ Allen Wrench (located on the fuel pump) clock-wise to increase, counterclockwise to decrease. Do not exceed 200 PSI.

FIELD REPAIR INSTRUCTIONS

Fuel Pump:

Remove the screws 10/32″ Allen Head from the machine hood.
Remove louvered hood.
With a 9/16″ wrench, loosen (DO NOT REMOVE) the two 3/8” x 3/4″ HH NC serrated ﬂ ange bolts that secure the front panel.
With a 2.5 mm hex head wrench (Allen Wrench), loosen the three set screws that hold the fuel pump in the blower motor housing located on Idromatic Boiler Assembly.
Carefully remove the fuel pump (Item #53) from the blower motor, leaving the ﬂ exible zinc fuel line connected, carefully bend the fuel line and fuel pump away from the blower motor.
Locate the fuel pump/fan motor coupling.
Inspect the coupling for damage. The inside di-ameter of fuel pump coupling requires ﬂ at on one side to engage fuel pump, and the outside diameter requires two male notches to engage the blower motor.
Perform a check to see if the fuel pump is turning freely. Use an open end 7mm wrench or small adjustable wrench on fuel pump shaft.
Spin the fuel pump over in both directions using the wrench for leverage. When the fuel pump is turning freely (almost to the point you could turn it by hand) it is ready to reinstall.
Align fuel pump coupler on pump shaft/fan motor. Slide pump into fan motor. Secure pump with the three set screws.
Test machine (make sure):
- Blower motor spins
- Fuel is on
- Machine has power to it
- Switch is on
- Flow of water through machine
- Thermostat is turned up
- Flow switch is adjusted properly
When machine is operating properly, turn machine off, tighten front panel, and install hood and 13 self tapping screws with recess washers.
