PRE-SPRAY AND TRAFFIC LANE APPLICATIONS:
Hydro-Force injection sprayers eliminate the has-
sles of measuring and mixing. We recommend you
keep an extra 5-quart container or two on your truck
to make sure you never run out and to facilitate quick
changes of your chemical containers. Remember that
Hydro-Force sprayers automatically mix at a 1 to 8
ratio. If your 5-quart container is full then that is the
same as holding an 11 gallon pump sprayer of regu-
lar, ready to use pre-spray.
Hydro-Force injection sprayers offer better pene-
tration and overall coverage than other sprayers. It is
therefore possible to pre-spray your jobs up to 45
minutes before that area needs to be cleaned. An
effective way to use the Hydro-Force sprayer for pre-
conditioning is to start at the door coming into the
house; spraying all the traffic areas, and work your
way to the farthest point back in your job. You have
then completed your pre-conditioning in just seconds
and are prepared to hook up your wand and start
cleaning your way out.
On larger jobs, or jobs involving more than an
hour of cleaning time, it is recommended that you
pre-spray an area that will take no longer than 45
minutes to clean. You can then hook up your Hydro-
Force again and pre-spray another large area.
APPLICATION OF CARPET PROTECTORS:
This highly profitable procedure is often passed
up on many jobs because it is too big of a ‘hassle’.
Operators will not mention the availability of protec-
tors because they are running short on time and must
hurry to their next job, or they don’t want to take the
time to rinse tanks then measure, mix and pump.
Hydro-Force injection sprayers bypass these has-
sles and encourage you to apply carpet protectors. Go
to your machine, shut off the chemical and, if you pre-
fer, your heat. You should then take a 5 quart contain-
er with clean water (adding an ounce or two of acid
or vinegar will help) to your Hydro-Force injection
sprayer unit. Take off your traffic lane bottle and put
on clean water. Run your Hydro-Force injection spray-
er for approximately 20 seconds or until all soap is out
of your lines. You may then put on your 5 quart con-
tainer with carpet protector in it. Your product should
be concentrated and diluted at 1 to 8 for application
on damp carpet. If this is a difficult dilution to reach
you may remove the metering tip to obtain a 1 to 4
ratio. If you are using Scotchgard® or a Teflon® prod-
uct on dry carpet you should dilute them 1 to 1 with
water before you use them with a Hydro-Force injec-
tion sprayer. Whether you use Maxim™ or another
product, you will find that a 5 qt. container will go a
long way. 5 qts. diluted 1 to 8, gives you 11 gallons of
ready to apply protector. With a coverage rate of 300
square. ft. per gallon, 5 qts. of protector will cover
3,000 square ft. Keep in mind that your Hydro-Force
injection sprayer is spraying 3 to 4 times the amount
of product your normal pump sprayer is putting out.
This means you must move quickly to avoid over-
applying. Protector should be applied in even, slightly
overlapping strokes. You should proceed from the
entrance again working your way toward the farthest
point.

TROUBLE SHOOTING GUIDE
The Hydro-Force injection sprayer is used to quickly, and evenly apply pre-spray, protector
and other chemicals over large areas. A specially designed valve injects chemical into the
high-pressure water flow coming from the machine and automatically dilutes it at the
desired ratio. A Hydro-Force injection sprayer can be used at pressures as low as 50 PSI or as
high as 1,000 PSI. All Hydro-Force sprayers are set at the factory to be used at water pressures
of 400 P.S.I. for a dilution ratio of 1:8, but can easily be configured to work at lower pressures
by simply changing the metering tip (see Metering Instructions below). The water flow is
automatically reduced as it passes through the injector valve, thus reducing the pressure
approximately 64%. To obtain the actual working pressure of your Hydro-Force, multiply your
incoming pressure by 36%.
