Safety

WARNING

PEOPLE OR OBJECTS CAN BE HURT OR DAMAGED IF THIS UNIT IS NOT USED CORRECTLY!

• Failure to read all the instructions before operating the unit may result in personal injury or death from the improper use of the chemical solution. Anyone handling, operating or using the unit must read and understand the instructions in the manual.

• The buyer assumes all responsibility for safety and proper use by the instructions.

• Using or servicing the unit without appropriate personal protective equipment (PPE) may result in serious injuries such as burns, rashes, eye, throat or lung damage and death. Always wear PPE as indicated in the Safety Data Sheet (SDS) when using or servicing the unit. Protect eyes, skin, and lungs against drifting spray.

• Chemical solutions may pose a health risk and death if they contact the skin or eyes, and 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. Release any remaining air pressure by opening the discharge ball valve. 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 open ball valves with chemicals in the tank, unless the ball valves are connected to an appropriate location for chemical discharge. Never point the discharge valves at yourself, another person, or any object you do not want to be covered in chemicals.

• Never operate the unit without the lid on.

• Do not use the unit if an overflow hose is not installed. If chemical flows from the overflow port, shut down the unit immediately and correct the problem before proceeding.

• Using incoming air pressure exceeding 80 psi (5.5 bar) may result in pressure buildup, explosion, serious injury or death. DO NOT exceed 80 psi (5.5 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 vapours. Always flush the unit with fresh water thoroughly when switching from an alkaline to an acid or an acid to
  an alkaline.

NOTICE

• 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.
• Use of an air lubricator before the unit may result in diminished performance and damage to the unit. Do not use an air lubricator before the unit.
• Moisture in the airlines will damage the pump and diminish the pump’s life. The air must be filtered, clean, dry and free of moisture. If needed, install an air dryer before the unit.

Installation Instructions

1. Remove components from the packaging, and select the desired area to mount the unit.

2. Ensure the mounting bracket is oriented correctly, and secure it to the wall using the provided hardware.
   Note: Use a ¼ in. drill bit to drill holes for the plastic anchors. Two holes should be 8 in. (20.3 cm) apart horizontally.

3. Mount the unit by connecting the bracket located on the back of the tank to the bracket on the wall.

4. Loosen all 4 screws and slowly remove the lid.
   Note: Use caution during lid removal; the light indicator and power supply are not secured to the unit.

5. Remove indicator light and housing from parts packages.

6. Using the included instructions, wire the indicator light assembly to the controller and mount it in a suitable location. Wiring not included.

7. Connect one or more of the ball valves on the underside of the unit to your existing metering pump(s).

8. Connect a hose to the suction barb of the fluid pump. Maximum draw length is 30 ft (0.3 m).
   Note: Suction hose and strainer are not included with the unit. These can be purchased separately.

9. Connect a hose to the overflow port. Run the hose back to your chemical source or to another location that is suitable for chemical discharge.

10. Verify the ball valves on the underside of the unit are in the closed position.

Maintenance

WARNING

Performing any maintenance with the unit connected to the air supply and/or electrical power may result in serious injury or death. Before conducting any maintenance, always ensure that the unit has been drained and disconnected from both compressed air and electrical power. 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.

Troubleshooting Your Unit

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

The 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.
The pump is cycling improperly| •     Check for low air pressure or a clog in the fluid lines.
Air passes through the pump without cycling| •     The pump needs to be replaced.
The tank will not fill and/or the pump is not cycling| •     Check to ensure the PVC ball valve is in the open position.
The unit operates at a reduced pressure| •     Check the 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.

The indicator lamp is on and the on-board LED is red| •     Unit is underfilled. Inspect the unit with the following instructions:

1.    Check for an empty chemical source tank.

2.    Press the PRIME button to prime the tank.

The indicator lamp is flashing and the on-board LED is red| •     Unit error. Inspect the unit with the following instructions:

1.    Unplug the unit and inspect the components. Plug back into the power source.

2.    If the error persists, replace the level sensor.
