• Chemical solutions may pose a health risk and death if they contact the skin or eyes, are inhaled or swallowed. Always read and follow all chemical safety precautions and handling instructions provided by the chemical manufacturer and the SDS associated with the chemical solution before using the unit.
• Pressure within the equipment may cause an unexpected release of the chemical solution and cause serious injury such as burns, rashes, eye damage, throat or lung damage and death.
• Always depressurize and clean the unit after each use. Never leave the unit unattended while pressurized.
• Using the unit with fluid temperatures above 100°F (37.8°C) may result in scalding, burns, serious injury or death. DO NOT use a solution with a temperature above 100°F (37.8°C).
• Operating the unit when damaged or leaking may result in exposure to chemical solutions, serious injury or death. Never use the unit if it is damaged or leaking.
• Never point the discharge wand at yourself, another person, or any object you do not want covered in chemical.
• Using incoming air pressure exceeding 100 psi (6.9 bar) may result in pressure buildup, explosion, serious injury or death. DO NOT exceed 100 psi (6.9 bar) incoming air pressure when operating the unit.
• Use of hydrocarbons and flammable products may result in explosions, fire and serious injury or death. Never use hydrocarbons or flammable products with the unit.
• Mixing an alkaline with an acid may result in a chemical reaction. Overheating of the mixture may cause it to splatter caustic compounds or release hazardous fumes, gas and vapors.

Service Guide

WARNING Performing any maintenance with the unit pressurized and connected to the air supply may result in serious injury or death. Always ensure that the unit has been depressurized and disconnected from the air supply before conducting any maintenance. Servicing or modifying this unit with parts not listed in this manual may cause the unit to operate improperly. Do not use unauthorized parts when servicing the unit.

Maintaining Your Unit
To keep your unit operating properly, periodically perform the following maintenance procedures:

• Inspect the pump for wear and leaks.
• Inspect all hoses for leaks or excessive wear. Make sure all hose clamps are in good condition and properly secured.
• Replace the filter located within the air regulator as needed. Clean by unthreading the air regulator bowl from the air regulator.
• Check the suction line and filter for debris. Clean as needed.
• Drain your air compressor tank regularly to help extend pump life. An air source with a high moisture content will accelerate pump wear.

Note: If your air source has a high moisture content, install a water separator to the air fitting on the backplate. See Page 8 for more details. (Back plate assembly).

Servicing Your Unit
Most repairs on the unit can be performed with the following tools:

• Crescent wrench (2x)
• ⁷/16 in. (11 mm) open-ended wrench
• Flat head screwdriver
• Thread seal tape

• 2 Phillips head screwdriver

• 3 Phillips head screwdriver

• Hose cutters
• Knife

Troubleshooting Your Unit

If your unit is not operating properly, try using these troubleshooting tips:

Air regulator bowl or air filter has debris such as water, oil, or rust particles| •   Clean by unthreading the air regulator bowl from the air regulator.
Pump is cycling faster than normal| •   Verify product is getting to the pump with these steps:

1.    Make sure the tank has chemical solution in it.

2.    Ensure the suction line valve is open completely.

3.    Inspect suction line and strainer for debris or damage.

•   If these steps are confirmed, the pump may need to be replaced.

Pump is cycling slower than normal| •   Verify there is no obstruction on the outlet side of system with these steps:

1.    Inspect discharge hose assembly for build up.

2.    Verify unit is supplied with proper air supply.

•   If these steps are confirmed, the pump may need to be replaced.

Air passes through the pump without cycling| •   The pump needs to be replaced.
The unit operates at a reduced pressure| •   Check suction line and strainer for debris or damage. Clean or replace as needed. To prevent damage to the unit, the strainer must always be used.

•   Check the air compressor supplying the unit. If the pressure is less than 40 psi (2.8 bar), turn off the unit until the compressor can catch up.

•   If the air supply is 50 psi (3.4 bar) or above, check the air gauge, which should read near 50 psi (3.4 bar). If the air gauge reads more or less than 50 psi (3.4 bar), adjust the pressure by turning the knob on the top of the air regulator.
