Turn burner off and open spray gun to allow water to flow and cool coil to 100°F before turning machine off. 24. Before disconnecting high pressure hose from hot water outlet, turn off burner to allow water to cool to 100°F, then turn off pump motor and water supply and operate spray gun to relieve back pressure in hose. This will prevent coil damage from thermal expansion. CAUTION: This machine produces hot water and must have insulated components attached to protect the operator. INSTALLATION Place machine in a convenient location providing ample support, draining and room for maintenance. This machine is intended for indoor use. Machine must be stored indoors when not in use. Location: The location should protect the machine from damaging environmental conditions, such as wind, rain, and freezing. 1. 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. Normal precautions should be taken by the operator of the machine to prevent moisture from reaching the electrical controls. 2. It is recommended that a partition be made between the wash area and the machine to prevent water spray from coming in contact with the machine. Excess moisture reaching any electric components or electrical controls will reduce machine life and may cause electrical shorts. 3. 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. Avoid small locations or areas near exhaust fans. 6 STP SERIES PRESSURE WASHER OPERATOR’S MANUAL COMPONENT IDENTIFICATION CAUTION HOT WATER: Must use insulated spray gun and wand. Nozzle ON-OFF Switch Adjustable Thermostat Discharge Nipple Wand Holder Downstream Detergent Injector Fresh Water Faucet (not included) Burner Chamber GFCI Pressure Switch Pump Unloader Garden Hose (not included) Burner Motor Detergent Bucket (not included) Nozzle Coupler Detergent Suction Hose Trigger Variable Pressure Insulated Wand Shark STP • 97-6153 • Rev. 3/04 Insulated Spray Gun Control Handle High Pressure Outlet Hose STP SERIES PRESSURE WASHER 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 adequate.) 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 fire. Connection: Connect the wand, nozzle, hose and spray gun (where applicable). On pipe thread connections, use teflon tape to avoid water leaks. (See Component Identification). Venting: Adding exhaust vent pipe to your oil fired burner is not recommended because restricted air flow causes carbon buildup, which affects the operation, and increases maintenance on the coil. If a stack must be used, refrain form 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. STARTING AND OPERATING INSTRUCTIONS To Start: CAUTION READ OPERATOR’S MANUAL THOROUGHLY PRIOR TO USE. 1. STOP! Read operator's manual before operating. Failure to read operation and warning instructions may result in personal injury or property damage. 2. Connect water supply hose and turn on water. 3. Check fuel tank and pump oil levels. Shark STP • 97-6153 • Rev. 3/04 OPERATOR’S MANUAL 7 4. Connect high pressure hose to discharge nipple by sliding quick coupler collar back. (If detergent is to be applied, insert a detergent injector as shown in Component Identification). 5. Insert quick coupler onto discharge nipple and secure by pushing quick coupler collar forward. 6. Securely attach the desired high pressure nozzle into wand coupler as described in steps 4 and 5. 7. Connect the power cord into the proper electrical outlet, then push in the GFCI reset button (Refer to serial plate for information.) 8. Grip spray gun handle securely and pull trigger. Then turn variable pressure control handle counterclockwise. 9. Turn switch to pump position. When a steady stream of water flows from the spray gun and wand, the machine is ready for cold water cleaning by turning the variable pressure control handle clockwise to raise the pressure. 10. For hot water washing, turn the switch to the burner position. (The burner will light automatically when the trigger on the spray gun is pulled.) To Stop: 1. If using the detergent injector, place the suction line in a bucket of water allowing detergent to be flushed from system. 2. Turn STP burner switch off and continue spraying water, allowing the water to cool. 3. After water has cooled to less than 100°F, turn the attached pressure washer off. 4. Turn garden hose water off. Open the spray gun to relieve remaining pressure. 5. Protect from freezing. 8 STP SERIES PRESSURE WASHER HOW TO USE THE DETERGENT INJECTOR WARNING: Some detergents may be harmful if inhaled or ingested causing severe nausea, fainting or poisoning.

Use clean fuel - kerosene, No. 1 home hearing fuel or diesel fuel. 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. 2. Check to see that the attached pressure washer water pump is properly lubricated. 3. Follow Winterizing Procedures to prevent freeze damage to pump coils. 4. Always neutralize and flush detergent from system after use. 5. If water is known to be high in mineral content, use a water softener in your water system or de-scale as needed. 6. Do not allow acidic, caustic or abrasive fluids to be pumped through system. 7. Always use high grade quality cleaning products. 8. Never run pump dry for extended periods of time. 9. If machine is operated with smoking or eye burning exhaust, coils will soot up, not letting water reach maximum operating temperature. (See section on Air Adjustments.) 10. Never allow water to be sprayed on or near engine or burner assembly or any electrical component. 11. Periodically delime coils 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 this equipment clean and dry. The areas around the Shark washer should be kept clean and free of combustible materials, gasoline and other flammable vapors and liquids. OPERATOR’S MANUAL 9 water into a 5 gallon bucket. Place a short section of garden hose into bucket and connect it to machine. Elevate bucket and turn pump on to siphon anti-freeze through machine. If compressed air is available, an air fitting can be screwed into the inlet connector and, by injecting compressed air, all water will be blown out of system. High Limit Hot Water Thermostat: For safety, each machine is equipped with a high limit control switch. In the event that the temperature of the water should exceed its operating temperature, the high limit control will turn the burner off until the water cools. Pumps: Use only SAE 30W non-detergent oil. Change oil after the first 50 hours of use. Thereafter, change the oil every three months or at 500 hour intervals. Oil level should be checked by using the dipstick found on top of the pump or the red dot visible through the oil gauge window. Oil should be maintained at that level. 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 Shark Deliming Powder (part #9-028008) will remove lime and other deposits before coil becomes plugged. (See Deliming Instructions for use of Shark Deliming Powder.) Deliming Coils: Unloader valves are preset and tested at the factory before shipping. Occasional adjustment of the unloader may be necessary to maintain correct pressure. Call your local dealer for assistance. Periodic flushing of coils is recommended. 1. Fill a container or optional float tank with 4 gallons of water, then add 1 lb. of deliming powder. Mix thoroughly. 2. Remove wand assembly from spray gun and put spray gun into container. Secure the trigger on the spray gun into the open position. 3. Attach a short section (3-5 ft.) of garden hose to machine to siphon solution from an elevated container. Turn pump switch on, allowing solution to be pumped through coils back into the container. Solution should be allowed to circulate 2-4 hours. 4. After circulating solution flush entire system with fresh water. Reinstall wand assembly to spray gun. Winterizing Procedure: Removal of Soot in Heating Coil: Damage due to freezing is not covered by warranty. Adhere to the following cold weather procedures whenever 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 machine in a heated room. If this is not possible then mix a 50/50 solution of anti-freeze/ In the heating process, fuel residue in the form of soot deposits may develop between the heating coil pipe and block air flow which will affect burner combustion. When soot has been detected on visual observation, the soot on the coil must be washed off after coil has been removed using the following steps: The flow of combustion and ventilating air to the burner must not be blocked or obstructed in any manner. MAINTENANCE AND SERVICE Unloader Valves: Shark STP • 97-6153 • Rev. 3/04 10 STP SERIES PRESSURE WASHER 1. Remove the tank head assembly by lifting the tank head off. 2. Remove the two pipe nipples and associated fittings. 3. Lift the coil out of the outer wrap. CAUTION: the coil weighs about 80 lbs. Use proper lifting techniques. 4. Clean, repair and replace the coil by reversing the above steps. Coil Reinstallation Reinstall by reversing the above steps 4 through 1. Rupture Disk If pressure from pump or thermal expansion should exceed safe limits, the rupture disk will burst, allowing high pressure to be discharged through hose to ground. When the disk ruptures, it will need to be replaced. 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 unit malfunction could result from contamination. Ignition Circuit: Periodically inspect wires, spring contact and electrodes for condition, security and proper spacing. For transformer test (CAUTION 10,000 VOLTS) use defect free insulated screwdriver and keep fingers off blade! Lay blade across one contact: OK if arc will span 1/2" between end of blade and other contact (see following illustration). Electrode Setting: Beckett 5/32" Gap 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. Fuel Control System: The STP utilizes a fuel solenoid valve located on the fuel pump to control flow of fuel to the combustion chamber. This solenoid is activated by a pressure switch located on the unloader valve. When an operator releases the trigger on the spray gun, the pressure drops, allowing the pressure switch to activate the fuel solenoid. The solenoid then closes, shutting off the supply of fuel to the combustion chamber. Controlling the flow 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 firing. Fuel Pressure Adjustment: To adjust fuel pressure, turn the adjusting screw with a screwdriver (located on the fuel pump) clockwise to increase, counterclockwise to decrease. Do not exceed 200 PSI. Air Adjustment Machines are preset and performance tested at the factory — elevation 100' above sea level. A one time correction for your location will pay off in economy, performance and extended service life. If a smoky or eye-burning exhaust is being emitted from the stack, two things should be checked. Next, check the air adjustment on the burner. An oily, black, smoky fire indicates a lack of air and the air band should be moved to allow the air to flow through the burner. Sharp, eye-burning fumes indicate too much air flowing through the combustion chamber. The air band should be moved to allow less air to flow through the burner.
