1.1 Limited Warranty Protection Plan

In short This section sets out the Kaivac warranty periods, which depend on the chemicals used with the machine. Warranty claims need a Return Authorization Number (RAN) from Kaivac, Inc. Customer Service, and wear items are excluded.‌‌​⁠​​‍‌​​⁠⁠‌‍‌⁠​‌‍⁠​​​​​​‌​​​​‌​⁠​​‍‍⁠​⁠‌‌‌​​⁠‍‍‍‍⁠​⁠‌‍‌⁠​‍

The Kaivac has been engineered and tested to provide long lasting performance. This warranty covers defects in workmanship or materials under normal use and service from the date of purchase.‌‌​⁠​​‍‌​​⁠⁠‌‍‌⁠​‌‍⁠​​​​​​‌​​​​‌​⁠​​‍‍⁠​⁠‌‌‌​​⁠‍‍‍‍⁠​⁠‌‍‌⁠​‍

1.3 SAFETY PRECAUTIONS

In short This section lists the safety rules for using the Kaivac, including electrical safety and grounding. Read the operating instructions first, use only a properly grounded outlet, and test the ground fault circuit interrupter before each use.‌‌​⁠​​‍‌​​⁠⁠‌‍‌⁠​‌‍⁠​​​​​​‌‍​​​‌​⁠​​​‌⁠​‌‌‍‍​⁠‌⁠‌‍⁠​‌​​⁠⁠‍‍‍

IMPORTANT SAFETY INSTRUCTIONS—SAVE THESE INSTRUCTIONS‌‌​⁠​​‍‌​​⁠⁠‌‍‌⁠​‌‍⁠​​​​​​‌‍​​​‌​⁠​​​‌⁠​‌‌‍‍​⁠‌⁠‌‍⁠​‌​​⁠⁠‍‍‍

CAUTION: To reduce the risk of injury, read operating instructions carefully before using.
WARNING: Risk of injection or injury to persons – do not direct discharge stream at persons.
WARNING RISK OF ELECTROCUTION:
  • Connect to a properly grounded outlet. Do not remove ground pin.
  • Inspect cord before using – do not use if cord is damaged.
  • Keep all connections dry and off the ground.
  • Do not touch plug with wet hands.
  • This product is provided with a ground fault circuit interrupter built into the power cord. If replacement of the plug or cord is needed, use only identical replacement parts.
  • Test the ground fault circuit interrupter (GFCI) before each use.
  • Do not close a door on the cord or pull the cord around sharp edges or corners.
  • Keep the cord away from heated surfaces.
  • Do not spray liquid from the Kaivac onto electrical outlets or on any electrical devices.
  • Turn off the unit before unplugging.
  • Do not pull on the cord to unplug. Grasp the plug at the outlet and pull.

Grounding Instructions:

THE KAIVAC MUST BE GROUNDED. If it should malfunction or stop working, grounding provides a path of least resistance for the electrical current and reduces the risk of electrical shock. The Kaivac is equipped with a ground fault circuit interrupter (GFCI) to further reduce danger and risk of electric shock. It must be maintained and tested regularly. An equipment grounding cord and plug is included with the unit. Cutting off the ground wire or using a cord with an ungrounded plug will void the warranty on the Kaivac.

Improper connection of the equipment grounding cord can result in the risk of electrical shock. Ask a qualified electrician or service person to check the outlet grounding if you are unsure. Do not modify the plug provided with the Kaivac. If it will not fit into the outlet, have a properly grounded outlet installed by a qualified electrician.

WARNING: When using this product, basic precautions should always be followed, including the following:
  • Read all the instructions before using the product.
  • To reduce the risk of injury, close supervision is necessary when a product is used near children.
  • Know how to stop the product and bleed pressures quickly. Be thoroughly familiar with the controls.
  • Stay alert – watch what you are doing.
  • Do not operate the product when fatigued or under the influence of alcohol or drugs.
  • Keep operating area clear of all persons.
  • Do not overreach or stand on unstable support. Keep good footing and balance at all times.
  • Do not use to pick up flammable or combustible materials.
  • Follow the maintenance instructions specified in the manual.

Personal Protective Equipment (PPE): It is recommended to wear proper personal protective equipment as required by the chemical product label instructions used in conjunction with the Kaivac.

3.0 MAINTENANCE

3.1 MACHINE MAINTENANCE

In short This section lists what to check or do for each part of the machine: floor tool, spray gun, hose, tanks, leaks, electrical system, vacuum wand and HEPA filter. Always unplug the machine before lifting the electric cover assembly.‌‌​⁠​​‍‌​​⁠⁠‌‍‌⁠​‌‍⁠​​​​​​⁠​​​​‌​⁠​​‌‌​‍‌‍​​⁠⁠​‌​⁠​⁠​‍⁠‌‍​​‍
CAUTION Always make sure machine is unplugged before lifting electric cover assembly
ItemProcedure
Floor Squeegee
  • Check condition of squeegee blades and wheels on the floor tool.
  • Rough floor surfaces will cause the blades and wheels to wear out more quickly. Replace as necessary
Spray Gun
  • Check spray pattern. If spray pattern will not pinpoint, clean orifice by removing it with an Allen wrench and flushing. Replace if needed.
  • If nozzle becomes difficult to move from high to low pressure lubricate nozzle with lithium grease.
Pressure Hose
  • Wipe clean after each use.
  • 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 plugged up. 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.
  • Electric cord must be inspected for tears or cuts in the insulation.
Vacuum Wand
  • Use a wire brush or coarse brush with acid cleaner or other 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

3.4 VACUUM DIAGRAM

In short This section shows how air and recovered liquid travel through the vacuum system. Flow runs from the vacuum wand intake through the hose to the vacuum tank, then through the float switch, the 3-stage vacuum and the HEPA filter to the exhaust.‌‌​⁠​​‍‌​​⁠⁠‌‍‌⁠​‌‍⁠​​​​​‌​‌​​​‌​⁠​​​‍​​​​⁠​‌​‌⁠‌​​⁠​‍‍​⁠⁠‍‌
Vacuum system flow diagram. Intake at vacuum wand leads through a combination slinky and rigid vacuum hose into the vacuum tank. A float switch on the tank leads to the 3-stage vacuum, which feeds the HEPA filter and then the exhaust. The 3-stage vacuum and HEPA filter sit inside a dashed box labeled black box compartment.

3.4 PUMP DIAGRAM

In short This page shows a flow diagram of the pump system. It traces how water moves from the water tank through the pump and unloader, picks up chemical from bottle A (and bottle B on dual chemical configurations), and goes to the spray gun.‌‌​⁠​​‍‌​​⁠⁠‌‍‌⁠​‌‍⁠​​​​​‌​‍​​​‌​⁠​​​‍⁠‍​‍‍⁠⁠‍‍‌⁠‌​⁠‍‌⁠‌​⁠‍⁠
Pump system flow diagram. Water tank with filter feeds the pump, then the unloader with unloader check valve and a pulse hose to the chemical injector with check valve. Chemical bottle A and chemical bottle B, each with draw tube, chemical cap, chemical cap check valve and chemical tip, feed the chemical valve, which leads to the chemical injector. The pressure hose runs through the pressure hose mini ball valve to the spray gun and spray nozzle. The pump, unloader and water tank are inside a dotted black box compartment outline. A note says chemical B only applies to dual chemical configurations.

3.4 ELECTRICAL DIAGRAM

In short This page gives the wiring diagram for the machine. It shows how the GFCI plug connection feeds the vac motor and pump circuits through their circuit breaker switches, and where the hour meters and rectifier sit.‌‌​⁠​​‍‌​​⁠⁠‌‍‌⁠​‌‍⁠​​​​​‌​⁠​​​‌​⁠​​‍‍‌‌​​‍‍‌‌‌​​‌​‌‌⁠‍‍‌‌‍⁠
Wiring diagram: a plug connection to GFCI with black, green and white wires feeds a vac motor through the vac motor circuit breaker switch, with an hour meter on the vac motor branch. The pump circuit breaker switch feeds a rectifier (black, white and red wires) and the pump with its own hour meter. A dashed box at the right shows the alternate 150 PSI pump wiring, with black, white and green wires and a connection to the hour meter. A note says the 500 PSI pump configuration is shown and refers to the 150 PSI PUMP DIA for 150 PSI pump applications.
