Operation
1) Place the RA-650 upright on a level and stable surface with the handle up.
2) Remove the dust cover.
3) Plug the RA-650 into a grounded 115 volt grounded outlet with the correct voltage and
amperage. For maximum protection against electrical shock, ALWAYS use a circuit that
is protected by a ground fault circuit interrupter. If you are unsure about the outlet, check with
a qualified electrician or service person. Do not use an adapter or extension cord.
4) To switch the unit on, locate the control panel and turn the variable speed switch clockwise
to the desired speed setting.
5) Operate unit until area is clear of unwanted contaminants or until filters need to be changed.
The control panel has a filter change light which illuminates when the HEPA filter needs to
be changed. See section on changing filters for instructions.
Auxiliary/GFCI Outlet/Daisy Chain
You can interconnect (“daisy-chain”) up to three RA-650’s to customize your air filtration needs.
The GFCI will “trip” if it detects a sudden “ground fault,” or overload and interrupt the
electric current. When the GFCI “trips,” unplug the unit and look for potential hazards such as
standing water, frayed cords, or anything that would cause a dangerous electrical problem. If
such a situation exists, plug the RA-650 into a different outlet and then push the “reset”
button which is located between the 2 outlets on the GFCI. If the unit will not operate check the
circuit breaker section below.
