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 or 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 in accordance with the instructions.
Using or servicing the unit without appropriate personal protective
equipment (PPE) may result in serious injury 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, 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).
Some components may be hot during and after use. Use caution when servicing or handling the
equipment.
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.
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. Always flush
the unit with fresh water thoroughly when switching from an alkaline to an acid or an acid to
an alkaline.
Never point the discharge wand at yourself, another person, or any object you do not want covered
in chemical.
Keep battery box lid closed and latched at all times unless accessing battery. Do not use with lid open
or damaged. Do not expose unit to liquids, cleaning solutions, foam, or rain. The battery pack is not
waterproof. Do not submerge in liquid. If battery pack gets wet, allow to dry before further use.
Using the unit with unapproved devices may result in a risk of fire, shock or personal injury. Only use
with 24V Equip Series compatible equipment.
When not in use, store unit indoors in a cool, dry location. Keep unit away from unauthorized users. To
prevent premature battery failure, do not store battery in a depleted state for long periods of time.

Troubleshooting Your Unit
V20231110 • Page 5 of 14Model: FI-BP-20N
Issue Solution
Pump is cycling improperly • Verify pump did not fail from chemical attack, or electrical malfunction.
• Ensure proper chemical and concentration are being used.
• Inspect suction line and strainer for debris or damage.
• Needle valve may be open too far. Close and readjust the needle valve.
Foam comes out wet, no matter
where the needle valve is
positioned
• The check valve may need to be replaced.
• Verify correct chemical concentration is being used.
• If only the fluid pump is running, the electric air compressor may need to be
replaced.
• Check if the wadding is plugged. Remove and inspect it by following the
instructions below:
1. Verify the unit does not have the battery installed or the power on.
2. Relieve all stored pressure in the unit by opening the ball valve, or
squeezing the trigger handle.
3. Unthread the discharge wand from the ball valve or spray gun.
4. Remove and inspect the wadding from inside the wand.
Note: Ensure tubing stays inside of wand when removing wadding.
5. Replace wadding if necessary. Attach wand back onto the ball valve or
spray gun.
Sporadic wet foam • Verify correct chemical concentration is being used.
• Ensure discharge hose is not kinked or damaged.
• Inspect wadding. Replace wadding if it is clogged.
• If wadding is next to spray tip, replace tubing inside the discharge wand.
Sporadic dry foam • Inspect suction line and strainer for debris or damage.
• If pump is cycling improperly or has failed, replace the pump.
The unit operates at a
reduced pressure
• Inspect 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.
• Inspect wadding. Replace wadding if necessary.
Battery will not completely
charge
• Place a secondary battery on the charger. If the secondary battery charges as
expected, it indicates that the initial battery is faulty and should be replaced.
• If the problem continues to occur, the charger is bad. Replace battery charger.
Battery discharges too quickly • Battery has reached life expectancy. Replace battery.
Power button LED slow flashing • Dead battery, charge battery.
Power button LED fast flashing • Compressor startup failure. Reset with a power cycle.
• A faulty pump or compressor may need to be replaced.
Battery/charger fault light is
flashing
• Refer to the separate manuals supplied with the battery and charger for more
information regarding indicator and fault lights.
