Important Safety Instructions
!WARNING:
1. Use the Rainbow and its attachments and accessories only as described in this manual. Use only attachments recommended by the manufacturer.
2. To reduce the risk of electric shock, use indoors only.
3. Do not vacuum up anything that is burning or smoking, such as cigarettes, matches or hot ashes. Do not use to vacuum up flammable or combustible liquids, such as
gasoline or use in areas where they may be present.
4. When using the Rainbow as a vacuum cleaner, do not leave the Rainbow unattended when plugged in. Unplug from outlet when not in use. To reduce the risk of injury
from moving parts, unplug before cleaning, maintenance, or servicing, or when connecting other Rainbow attachments.
5. Switch off the Rainbow before unplugging from outlet.
6. Do not unplug by pulling on cord. To unplug, grasp the plug, not the cord.
7. Do not handle the Rainbow or plug with wet hands.
8. Do not pull or carry by cord, use cord as a handle, close a door on cord, or pull cord around sharp edges. Do not run the Rainbow over cord. Keep cord away from
heated surfaces.
9. Do not use with damaged cord or plug. If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified person in order
to avoid a hazard. If appliance is not working as it should, has been dropped, damaged, left outdoors or dropped in water, return it to a service center.
10. Do not insert any object into openings on the Rainbow unit. Do not use if any openings are blocked; keep openings free of dust, lint, hair and any other materials that
may reduce airflow.
11. Keep hair, loose clothing, fingers and all parts of body away from openings and moving parts.
12. Use extra care when cleaning on stairs.
13. Do not immerse the Rainbow or hose in water or other liquids during use or cleaning. To reduce the risk of electric shock, do not use any motorized nozzle on wet
surfaces -- use only on carpet moistened by the ordinary, approved cleaning process.
14. To reduce risk of fire and electric shock due to internal component damage, use only Rainbow cleaning products intended for use with this appliance.
15. The hose contains electric wires and connections. To reduce the risk of electric shock, do not use when damaged, cut or punctured. Avoid vacuuming up sharp objects.
In order to reduce the risk of electric shock, do not use or attempt to repair a damaged hose or use any other type of hose as a substitute. Servicing of the wet pick
up electric hose requires extreme care and knowledge of its construction. Servicing of a wet pick up electric hose should be done only by qualified service personnel.
16. The hose must be examined periodically for visible deterioration, such as abrasions, cracks, splits and other wear or damage.
17. The hose is to be used only for indoor household carpet cleaning applications using only manufacturer-recommended cleaning solutions.
THIS SYMBOL MEANS ‘PLEASE READ ALL
INSTRUCTIONS BEFORE USING THIS UNIT.’
IPX4 IS THE DEGREE OF PROTECTION
AGAINST INGRESS OF WATER.
THIS SYMBOL MEANS ‘CAUTION.’ When using an electrical appliance,
basic precautions should always be followed, including the following:

18. The Rainbow utilizes double insulation. A double-insulated appliance is marked with one or more of the following: The words “DOUBLE INSULATION” or “DOUBLE
INSULATED” or the double insulation symbol (square within a square). In a double-insulated appliance, two systems of insulation are provided instead of
grounding. No grounding mechanism is provided on a double-insulated appliance, nor should a means for grounding be added to the appliance. Servicing of a double-
insulated appliance requires extreme care and knowledge of the system and should only be done by qualified personnel. Replacement parts for a double-insulated
appliance must be identical to the parts they replace.
19. Always turn off the Rainbow before connecting or disconnecting the hose or any motorized nozzle.
20. Do not use without filters in place.
21. The Rainbow is equipped with an interlock switch located in the water basin baffle area that prevents the appliance from operating if the water basin is not properly
installed and latched. Do not bypass or defeat the interlock system.
22. Do not plug the Rainbow into a receptacle of an incandescent light fixture or use with an extension cord. Do not use with portable transformers or voltage converters. Do
not use to pick up flammable or combustible liquids, such as gasoline or use in areas where they may be present.
23. To reduce the risk of electric shock, the Rainbow has a polarized plug (one blade is wider than the other). This plug will fit in a polarized outlet only one way. If the plug
does not fit fully in the outlet, reverse the plug. If the plug still doesn’t fit into the receptacle, contact a qualified electrician to install the proper outlet. Do not change the
plug in any way.
24. The Rainbow can be used by children aged 8 years and above and persons with reduced physical, sensory, or mental capabilities or lack of experience and knowledge, if
they have been given supervision or instruction concerning use of the Rainbow in a safe way, and if they understand the hazards involved. Children should be supervised
to ensure that they do not play with the Rainbow. Cleaning and user maintenance shall not be performed by children without supervision.
25. Do not plug the Rainbow into a receptacle of an incandescent light fixture or use with an extension cord. Do not use with portable transformers or voltage converters.
26. This is a professional high-power piece of equipment and can cause electromagnetic interference. Please contact your local utility company regarding any special supply
connection requirements.
Servicing of Double-Insulated Appliance
In a double-insulated appliance, two systems of insulation are provided instead of grounding. No grounding means is provided on a double-insulated appliance,
nor should a means for grounding be added to the appliance. Servicing a double-insulated appliance requires extreme care and knowledge of the system and should be done
only by qualified Rainbow service personnel. Replacement parts for a double-insulated appliance must be identical to the parts they replace. A double-insulated appliance is
marked with the words “DOUBLE-INSULATION” or “DOUBLE-INSULATED.” The Symbol (square within a square) may also be marked on the appliance. Any servicing other than
cleaning should be performed by an Authorized Rainbow Distributor or Service Center.

Proper Use and Care
Change the water when dirty…
Do not clean too long with one filling of water. Check water
during cleaning, and if water becomes too thick with lint and
dirt, empty water basin and add fresh, clean water. For correct
water level, fill to top of post in center of water basin.
Always empty and clean the
basin…
Immediately after using the Rainbow, remove the water basin
and pour out the dirty water through the air intake opening.
Heavier particles will settle to the bottom of the basin as the
water is poured. Once water is poured, remove the remaining
heavier debris and dispose. Then wash the water basin with
soap and water. Rinse and dry thoroughly. If water basin is
stored within Rainbow unit, unit must be left in ‘open’ position to
allow parts to dry thoroughly.
!CAUTION: Always remove, empty and wash the water
basin when cleaning job is finished. This helps to avoid odors,
growth of germs and bacteria and the development of water
scum in the basin. Hand wash only. Not dishwasher safe.
Clean the separator…
For best performance, remove and clean the separator frequently.
If necessary, use the supplied Rainbow Separator Brush/Wrench to
loosen the nut. Clean the separator inside and out with soap and
water using the Rainbow Separator Brush. Clean and dry the flange
under the separator. Immediately after cleaning, dry and replace the
separator. Hand-tighten the separator nut. Do not force the separator
onto the threaded shaft.
!WARNING: Always replace the separator immediately
after cleaning (hand-tighten only). Do not operate the Rainbow
without the separator.
Clearing an obstruction from the hose...
If you notice decreased airflow when using the hose, the hose may
have become clogged. To clear the obstruction, turn off Rainbow
and disconnect from power source. Then, remove the exhaust
vent door on the rear of the Rainbow. Connect the hose coupling to
the exhaust air opening, making sure it is securely locked into place.
Place the hose handle wand into the air intake opening on the front
of the Rainbow. Turn the Rainbow on and jiggle the hose. Any dirt
stuck in the hose will be trapped in the Rainbow water basin.
Following a few basic maintenance routines will help provide you with years of trouble-free service from your Rainbow Cleaning System. Neglecting all or part of these
instructions may lead to decreased cleaning efficiency and potentially unnecessary service expenses.

9 | RAINBOW SRX
Proper Use and Care
Cleaning the attachments…
The floor and wall brush, dusting brush and upholstery tool can
be whisked clean with the open end of the Rainbow hose while
the Rainbow is running; or remove attachment and clean in
warm, soapy water. Allow to dry before replacing. If bristles wear
out or become damaged, contact your local Authorized Rainbow
Distributor for replacement.
Using the Airow Adapter…
The Rainbow Airflow Adapter reduces air noise through the air inlet
opening. It is recommended that the adapter be used when the
Rainbow is used as a blower or inflator. Simply snap the Airflow
Adapter into the air inlet opening before using the Rainbow as a
blower or inflator.
!CAUTION: Always clean attachments before using on fabrics. To avoid abrasions to
delicate surfaces, keep the dusting brush bristles clean.
!CAUTION: Do not use attachments to clean flat-screen televisions or computer screens.
To inate or blow air…
Use the inflator tool. The Rainbow inflator tool works great for
quickly inflating air mattresses, beach balls and other inflatable toys.
!WARNING: Be sure inflator pin is properly locked in
place. If not, it will be blown forcefully from the tool body.
INSTRUCTIONS:
1. Remove the rear exhaust panel on the Rainbow.
2. Attach Rainbow hose to the rear exhaust opening.
3. Set Airflow Control Setting on trigger to FULL POWER.
4. Attach inflator tool to hose handle.
5. Carefully insert the inflator pin into the inflator stem of the
object to be inflated.
6. Turn Rainbow switch to HIGH.
Using the Cushion Bag
This handy plastic bag removes stale, dusty air from cushions
and pillows and is sized to fit even your largest cushions. Begin
by placing a cushion in the bag. With the upholstery tool attached
to the end of the hose handle wand, hold the cushion bag tightly
in place around the wand, turn on the Rainbow and watch as
stale, dusty air is sucked out. Without letting go of the bag at the
wand, disconnect the hose from the front of the Rainbow and
attach to the Rainbow’s exhaust air opening. Your cushion is now
being “fluffed” with clean, water-washed air.
