• Do not use while tired or under the influence of drugs, alcohol, or medication.
• Use only the supplied battery charger. Do not handle the charger with wet hands.
• Do not use the unit while plugged into the battery charger.
• Be careful – a fully filled unit is heavy!! Do not make any sudden movements when using this unit with the shoulder strap.
• Do not overreach or stand on unstable support. Keep proper footing and balance at all times.
• Wear rubber gloves, rubber boots, goggles or face-shield, etc. Detergents and chemicals may cause injuries to the eyes and skin. Protect yourself from direct skin contact with the chemicals and debris found in the coil cleaning environment.
• Do not use any acid or cleaners that contain sodium or potassium hydroxide!! Call SpeedClean to check compatibility before using any chemical in the CoilJet®.

Operating Instructions

Pre-Operation Checklist

• Check for adequate water and chemical cleaner supply (use only mild cleaners).
• Make sure the battery has sufficient charge for normal operation.
• Check spray nozzles and make sure orifice is not blocked or worn to excess.
• Check pressure hose for wear or kinks.
• Check all connections, fittings, screws and fasteners.

Charging the Battery

1. The unit is supplied with a 12V sealed lead acid battery, which will provide up to 1 hour of continuous use or approximately 4-6 hours of intermittent use when fully charged.
2. It will take approximately 4 hours to charge a fully discharged battery.
3. Make sure the power switch is in the “Off” position when charging.
4. An orange/red light means the battery is charging, a bright green light means the battery is fully charged.
5. The unit can be left plugged in indefinitely – once the battery is fully charged, the battery charger will switch to a “maintain charge” mode.

Changing the Battery

1. The battery can be quickly removed from the unit, allowing the insertion of a fresh battery. Spare batteries and chargers are available – contact your local distributor or SpeedClean.
2. To replace the battery:
3. Turn power switch off.
4. Remove the battery door by pulling up.
5. Carefully remove the battery. Disconnect the battery terminal connectors from the battery.
6. Connect the battery connection wires to the fresh battery (Caution – black battery connection wire to the negative (black) battery terminal and red wire to positive (red) battery terminal.
7. Replace the battery in the battery compartment and replace the battery cover.

Normal Coil Cleaning Operation

1. Fill the water and chemical tanks. Before priming the pump, make sure chemical valve is fully closed and remove any nozzle from the spray gun.

2. Flip the power switch to the ON position.

3. Squeeze the spray gun trigger to prime the pump.
   NOTE: If you are having trouble priming the pump, make sure the water tank is completely full as well as having the chemical tank full, whether it’s with chemicals or water. Place the unit on a table or support, hold the spray gun below the level of the pump and squeeze the trigger until a steady flow of water appears.

4. Fully open the chemical valve (counter-clockwise). Squeeze the spray gun trigger repeatedly until chemical is primed.

5. Adjust chemical valve to desired dilution ratio (see chart on next page).

6. Attach nozzle to spray gun.

7. Apply water/chemical solution evenly to coils.

8. Close chemical valve finger tight (clockwise). DO NOT overtighten.*

9. If possible, let foaming coil cleaner solution sit for recommended dwell time (according to chemical instructions) to penetrate into coils.

10. Rinse coils with clean water.
    NOTE: There may be a ten second delay for the chemical to be removed from the hose.

11. Flip Power Switch to OFF. Always relieve the pressure by pointing the spray gun in a safe direction and squeezing the spray gun trigger.

Chemical Dilution Ratios
Turn Chemical Valve counter-clockwise to open, clockwise to close.

WARNINGS:

• The motor is equipped with an automatic shut-off that disconnects power when the spray gun trigger is released to maximize battery life. The unit may appear to be “off” (not running), but if the power switch is on or the system pressure is not relieved, the unit will discharge when the spray gun trigger is squeezed. Do not leave the unit in automatic shut-off condition for more than 10 minutes.
• The cords, wires, and/or cables supplied with this product may contain chemicals, including lead or lead compounds, known to the State of California to cause cancer and birth defects or other reproductive harm. Always wash hands after using.

General Maintenance & Storage

1. When done using the unit, run clean water through the pump.
2. Protect unit from freezing temperatures. Do not store unit outdoors.
3. The unit can be stored above freezing temperatures for short periods of time (less than 1 week) with liquid in the tanks.
4. To protect the unit from damage, chemical and water should be drained from the tanks and the pump and chemical valve flushed with clean water before the unit is placed in long term storage.
5. If the unit is to be stored for an extended period of time in an unheated location, pour about 1 quart of RV antifreeze into the tanks. Open the chemical valve and run the pump until antifreeze exits the spray gun. Turn unit off and relieve pressure. IMPORTANT: Use only RV antifreeze. Normal Antifreeze is corrosive and may damage the pump.
6. When using the unit after long term storage, flush with clean water before use.
7. During long term storage, plug the unit into the battery charger at least once a month to maintain battery life. The unit may be left plugged-in indefinitely.

IMPORTANT BATTERY INFORMATION: Always charge the unit after use. Leaving a sealed lead acid battery discharged may cause permanent damage. Use only the supplied “smart” battery charger that will never overcharge the battery. Overcharging a sealed lead acid battery will cause permanent damage.
