IMPORTANT SAFETY INSTRUCTIONS
This machine is only suitable for commercial use, for example in hotels, schools, hospitals, factories, shops
and offices other than normal residential housekeeping purposes.
When using any electrical appliance, basic precautions should always be followed, including the following:
NOTE: Read all instructions before using this machine.
WARNING!
To reduce the risk of fire, electric shock, or injury:
•Do not leave the machine unattended when it is plugged in. Unplug the unit from the outlet when not
in use and before servicing.
•To avoid electric shock, do not expose to rain or snow. Store, and use, indoors.
•Do not allow to be used as a toy. Close attention is necessary when used near children.
•Use only as described in this manual. Use only the manufacturer’srecommended attachments.
•Never add water over 54º C/130º F to the solution tank.
•Do not use with damaged cord or plug. If the machine is not working as it should, has been dropped,
damaged, left outdoors or dropped into water, return it to a service center.
•Do not pull by the cord, use the cord as a handle, close a door on the cord, or pull the cord around sharp
edges or corners. Do not run the machine over the cord. Keep the cord away from heated surfaces. To
unplug, grasp the plug, not the cord.
•Do not handle the plug, the cord, or the machine with wet hands.
•Extension cords must be 12/3 and no longer than 15 M. Replace the cord or plug immediately if the
ground prong becomes damaged.
•Do not put any object into openings. Do not use with any opening blocked; keep free of dust, lint, hair,
and anything that may reduce air flow.
•Keep loose clothing, hair, fingers, and all parts of body away from openings and moving parts.
•Do not pick up anything that is burning or smoking, such as cigarettes, matches, or hot ashes, or any
health endangering dusts. Do not use to pick up flammable or combustible liquids such as gasoline or
use in areas where they may be present.
•Turn off all controls before unplugging.
•Use extra care when cleaning on stairs.
•Connect to a properly grounded outlet only.
•Liquid ejected at the spray nozzle could be dangerous as a result of its temperature, pressure, or
chemical content.

INSPECTION:
Carefully unpack and inspect your COBRA-H for shipping damage. Each machine is tested
and inspected before shipping. Any shipping damage incurred is the responsibility of the
carrier. You should notify the carrier immediately if you notice damage to the box or to the
machine or parts.
CLEANING SOLUTIONS:
We recommend liquid cleaning chemicals. Powder chemicals may be used, but unless mixed
very thoroughly they could cause a build-up in the pump, lines, heat exchanger and/or quick
disconnects. Any problem caused by a chemical build-up is not covered by warranty. Use a
neutral cleaner with a pH between 5 and 10 to avoid premature wear of the pump, seals,
and/or other components. Damage caused by the use of strong chemicals is not covered by
the warranty.
MAINTENANCE:
For optimum performance flush the machine with clear water at the end of each working day.
Once a month, minimum, run a flushing compound through the machine to break up any
mineral or chemical build-up that may have formed. The vacuum motors and the pump do
not require any scheduled maintenance; however, the vacuum motors may require
replacement brushes after 1000 - 1500 hours. Clean the body with an all purpose detergent,
and protect it with an automobile interior polish. Lubricate the wheels, castors, and quick
disconnects with an all purpose silicone spray.

SET-UP and OPERATION:
1. Fill the holding tank with clear water and the detergent of your choice. Mix well. Although this machine is designed to
supply instant hot water, the addition of warm or hot water to the holding tank would be a plus factor. Never put water
hotter than 54 °C/130 °F in the tank.
2. Plug in cord #1. This cord runs the pump and vacuums.
3. Turn on the pump and spray through the cleaning tool for a few seconds to fill the lines with
solution.
4. Plug in cord #2 (identified by a red “H”). Wait 2 minutes for the heat exchanger to reach operating
temperature. You may now begin cleaning.
NOTE: It will take about 10 seconds for the initial heat to reach the wand.
BALL FLOAT VAC SHUTOFF:
When the recovery tank is full, the float system will shut off the incoming air flow and prevent water from entering the vacuum
motors. The float may not work properly if the float filter is clogged or if there is foam in the tank.
CAUTION: To avoid vac motor damage, always make sure the float filter is clean and the ball travels freely
before turning on the machine, and use a defoamer whenever foam is present.
