BATTERY INFORMATION

To recycle battery, call Kaivac Customer Care at 1-800-287-1136 to order a recycling box.
Disposal of batteries are regulated by federal law and must be done properly.‌‌​⁠‍‍​‍‌‌‍​‌​​​‍​‌‍​​​​​​‌‍​​​‌​⁠​​‌‌⁠​​​‌⁠​‍‌‌‌‍‍⁠⁠‌⁠‌‌​‍⁠

BATTERY INFORMATION

In short This section explains how to store, use and replace the lithium-ion battery. Keep it at room temperature, store it at about 50% charge, replace it when run time drops or after 4 years, and recycle old batteries rather than throwing them away.‌‌​⁠‍‍​‍‌‌‍​‌​​​‍​‌‍​​​​​​‌‍​​​‌​⁠​​‌‌⁠​​​‌⁠​‍‌‌‌‍‍⁠⁠‌⁠‌‌​‍⁠

Batteries and chargers: make sure your charger is compatible with your batteries, and set its charging algorithm to your battery pack before you use it.

Keep Batteries at Room Temperature: Store between 32 and 113 degrees F (0°C to 45°C). Avoid battery exposure to extreme temperatures. If shelving battery longer than (1) month, deplete battery to 50% charge during storage period (two bars on the battery indicator).

Batteries Lose Capacity Over Time: Batteries naturally deteriorate over time whether being used or not. If battery use instructions are properly followed, batteries deteriorate at a rate of approximately 10% run time per year but may vary by patterns of use.

Fully Discharge vs. Partial Discharge and the Effect on Battery Cycles: Unlike lead acid batteries, the Lithium-ion battery used with Kaivac equipment is not damaged by full or partial discharging. The expected battery hours of use are approximately 600 hours and 400 charge cycles. If you discharge battery only to 80%, then the user can expect to get more cycles (500 cycles). With dual batteries make sure to alternate batteries per charge in order to maximize for life capacity.

Extended Storage: It is recommended to discharge to 50% capacity (two bars on the battery indicator) and store in a cool location (between 32°F to 113°F or 0°C to 45°C). To avoid battery impact, store battery laying down on its side on lowest shelf, and secured. If battery is dropped or experiences an impact or damage, discontinue use and replace. Never use a damaged battery, as a damaged battery may act in an unpredictable manner resulting in fire, explosion, property damage, or personal injury.

Battery Gauge: The Kaivac provided battery comes with a built-in Battery Gauge or which shows the approximate run time for the current charge remaining.

Replacement - End of Life: Rechargeable batteries eventually wear out. When your Kaivac Battery run time is less than 55% (i.e. 50 minutes for non-quick change and 33 minutes for Quick Change batteries), Kaivac recommends replacing your battery. Regardless of run time, contact Kaivac to replace your battery after 4 years. Consult kaivac.com for information on recycling your old battery through a licensed disposal facility.

WARNING! RISK OF FIRE, EXPLOSION, PROPERTY DAMAGE, OR SERIOUS INJURY OR DEATH
DO NOT DISCARD BATTERY INTO TRASH! It is important to recycle your old batteries at your local authorized battery recycling facility or by calling 1-800-USA-CLEAN (1-800-872-2532) and selecting Option 3.

GROUNDING INFORMATION

GROUNDING INFORMATION

WARNING RISK OF ELECTRIC SHOCK OR FIRE

Grounding: Corded Units

In short Corded units must be plugged into a properly grounded outlet with the same plug configuration, with no adapter. The cord plug has built-in GFCI protection, and a damaged cord must be replaced with an identical or equivalent rated cord.‌‌​⁠‍‍​‍‌‌‍​‌​​​‍​‌‍​​​​​​‌⁠​​​‌​⁠​​‍⁠⁠‌⁠​‍‍⁠‍⁠‍‍⁠‌⁠⁠⁠​‌‍⁠⁠​

GROUND FAULT CIRCUIT INTERRUPTER PROTECTION (for spray systems only)‌‌​⁠‍‍​‍‌‌‍​‌​​​‍​‌‍​​​​​​‌⁠​​​‌​⁠​​‍⁠⁠‌⁠​‍‍⁠‍⁠‍‍⁠‌⁠⁠⁠​‌‍⁠⁠​

If your unit is a corded unit, it has been supplied with a ground-fault circuit-interrupter(GFCI) built into the plug of the power-supply cord. This GFCI device provides additional protection from the risk of electric shock. Should replacement of the plug or cord become necessary, use only identical replacement parts that include GFCI protection.

If your unit is a corded unit, it is for use on a nominal circuit and has a grounding attachment plug. Make sure that the appliance is connected to an outlet having the same configuration as the plug. No adapter should be used with this unit.

GROUNDING INSTRUCTIONS

If your unit is a corded unit, it must be grounded. If the unit should malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This unit is equipped with a cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged into an appropriate outlet that is properly installed and grounded in accordance with all local electrical codes and ordinances.

WARNING RISK OF ELECTRIC SHOCK
Improper connection of the unit-grounding conductor can result in a risk of electric shock. Check with a qualified electrician or service person if you are in doubt as to whether the outlet is properly grounded. Do not modify the plug provided with the unit by removing the ground pin on the plug – if the plug will not fit the outlet, have a proper outlet installed by a qualified electrician.

This unit comes with a grounded attachable extension cord. If damaged, replace with Kaivac® (OEM) cord, or if necessary an equivalent cord rated 120V, 15 amps, 3-wire, 14 GA. This cord must be attached and mechanically secured using the provided cord connector to use the unit.

Grounding: Battery Units

In short The charger on battery units must be grounded. Plug it into a properly grounded outlet that matches the plug, without an adapter and without removing the ground pin.

Batteries and chargers: make sure your charger is compatible with your batteries, and set its charging algorithm to your battery pack before you use it.

GROUNDING INFORMATION

GROUNDING INFORMATION (CONTINUED)

In short This page explains how to choose an extension cord of the right size for the unit using Table 1, and to use only three-wire outdoor cords with three-prong grounding receptacles. It also shows how to knot the unit cord and extension cord together so the connection stays firmly attached.‌‌​⁠‍‍​‍‌‌‍​‌​​​‍​‌‍​​​​​​‍​​​​‌​⁠​​‌​⁠‌‌⁠‌‌​⁠‌​​‌‍​​⁠‌‌‍⁠‍‌

Make sure your extension cord is in good condition and is the correct size for your unit. Table 1 shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the gage number, the heavier the cord. An undersized extension cord will cause a drop in line voltage resulting in loss of power and overheating.‌‌​⁠‍‍​‍‌‌‍​‌​​​‍​‌‍​​​​​​‍​​​​‌​⁠​​‌​⁠‌‌⁠‌‌​⁠‌​​‌‍​​⁠‌‌‍⁠‍‌

Use only three-wire outdoor extension cords that have three-prong grounding receptacles that accept the unit’s plug.

WARNING! RISK OF ELECTRIC SHOCK OR FIRE. To reduce the risk of personal injury due to a loose electrical connection between the unit’s plug and extension cord, firmly and fully attach the unit plug to the extension cord. Periodically check the connection while operating the unit to ensure it is fully attached. Do not use an extension cord that provides a loose connection. A loose connection may result in overheating, fire, and increases the risk of a burning.

To reduce the risk of disconnection of the unit’s cord from the extension cord during operations:

  • Make a knot as shown in Figure 1 below:

Figure 1 - Method of securing the appliance cord to the extension cord set

Two drawings of looping cords. (A) The cord set, labeled CORD SET, and the appliance cord, labeled APPLIANCE CORD, are tied together in a knot below the unplugged plug and receptacle. (B) The plug and receptacle are connected above the same knot.

  • Check for cuts or frays in the hose jacket, particularly at the end of the fittings. Replace hose if cuts are found.
Water Tank
  • Check condition of filter in water tank. Clean as needed.
  • Empty the water tank to prevent mildew and bacteria growth. Empty tank by dipping the vacuum hose into the water tank and transferring the water to the vacuum tank.
Vacuum Tank
  • Empty and flush vacuum tank.
  • Clean and disinfect.
  • Check the float shutoff screen to be sure it is not blocked or dirty. A plugged filter screen restricts airflow and results in reduced suction.
Leaks
  • Be alert for leaks around hoses, fittings, spray wand, tanks or elsewhere.
  • Discontinue use until leaks are repaired.
Electrical System
  • The ground fault circuit interrupter (GFCI) must be tested before each use.
  • Electrical cord must be inspected for tears or cuts in the insulation.
  • Inspect plug and be sure ground pin is in place.
Vacuum Wand
  • Use a wire or coarse brush with acid cleaner to remove residue from threads on the coupling and coupling nut. Apply grease when done.
HEPA Filter
  • Replace every 3-6 months depending on use.
Float Cage
  • Ensure cage is sprayed and cleaned daily to remove debris.
Battery Maintenance
  • Inspect battery, plugs, cords, splash cover (if included), and chemical-resistant plastic protective helmet (if included) before charging and after charging.
  • Charge and store battery indoors.
  • If included, the battery splash cover must remain in place. Without the battery splash cover, the battery housing may become damaged which may cause the battery to malfunction, which can result a fire, explosion, personal injury, and/or property damage.
  • Always keep helmet affixed to top of battery if your battery is so equipped.
  • To view the battery, temporarily move the splash cover (if included). Replace the splash cover after inspection. Do not use unit if battery shows any damage, including cracks, dents, holes, fraying, or missing pieces.
  • Once your battery run time is less than 55% (50 minutes for non-quick change and 30 minutes for quick change batteries), contact Kaivac to replace your battery. Regardless of run time, replace your battery after 4 years. Consult Kaivac.com for information on recycling your old battery.
  • DO NOT attempt to repair, service or modify the batteries or charger. Contact Kaivac Technical Support with any issues.
  • DO NOT use or store the NTC Unit, Omniflex Unit, or battery in refrigerated areas, in environments when the battery is in direct contact with liquids, or near flammable or combustible materials.
  • DO NOT charge or store battery for extended time (1 month or more) in temperatures below 40°F (4°C).
  • DO NOT use a battery or appliance that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behavior resulting in fire, explosion or risk of injury.
  • If unit is smoking or sparking, move outside to a fire-safe location immediately. If possible, disengage battery from unit, notify management, and call Kaivac Technical Support at 800-287-1136, Ext. 2
Splash Cover (if applicable)
  • Inspect splash cover for damage.
  • Clean and dry the splash cover.
  • Be sure the splash cover is secure.
