SAFETY PRECAUTIONS

Improper installation and operation could cause

personal injury and/or equipment and property

damage. Read and understand labels and the

Owner's Manual before installing, operating, or making

adjustments.

WARNING

• Before working with the equipment, secure all

loose-tting clothing and unrestrained hair.

• Before operating the sprayer system, verify

that all safety guards are in place.

• Always shut off vehicle before attempting to

attach, detach, or service sprayer system.

• Never attempt to take a unit off a truck with

liquid in it.

• Do not climb into or ride on the machine.

WARNING

Securely bolt and strap unit into place on the

vehicle bed using the optional UMK-200 bolt

kit and ratchet straps or similar. Unit must

be strapped down and bolted into position

before operating or transporting.

WARNING

Vehicle handling and characteristics will

change with the unit installed. Avoid any

sudden steering maneuvers, starts, or stops

that could create sloshing and instability.

WARNING

Always make sure personnel are clear of

areas of danger when using equipment.

Maintain 60' distance from all bystanders

when operating the sprayer system.

WARNING

Overloading could result in an

accident or damage. Do not exceed

GVWR or GAWR ratings as found

on the driver-side vehicle door

cornerpost. See Filling section to determine

maximum volumes of spraying material.

SAFETY

WARNING

Do not install the control for this product in

the deployment path of an air bag. Refer to

vehicle manufacturer's manual for air bag

deployment area(s).

WARNING

Inspect the unit periodically for defects. Parts

that are broken, missing, or worn out must be

replaced immediately. Do not alter any part of

the unit without prior written permission from

the manufacturer.

CAUTION

Brine is typically a clear to cloudy white

liquid with no odor. It may be irritating to the

eyes, skin, and respiratory system. For more

safety information on brine and other de-icing

materials, refer to the manufacturer's Material

Safety Data Sheet (MSDS).

CAUTION

Do not leave material in the unit for long

periods of time.

CAUTION

During the sprayer system installation

we recommend the addition of an OSHA

compliant Backup Alarm. This alarm is

required for OSHA governed employers.

CAUTION

• Do not operate a sprayer system in need of

maintenance.

• Before operating the sprayer system,

reassemble any parts or hardware removed

for cleaning or adjusting.

• Before operating the sprayer system,

remove materials such as cleaning rags,

brushes, and hand tools from the unit.

• Before operating the sprayer system, read

the engine owner's manual, if so equipped.

• While operating the unit, use auxiliary warning

lights, except when prohibited by law.

• Tighten all fasteners according to the

Torque Chart. Refer to Torque Chart for the

recommended torque values.

NOTE: Lubricate grease ttings after each use.

Use a good quality multipurpose grease.

FUSES

The electrical system contains several blade-style

automotive fuses. If a problem should occur and

fuse replacement is necessary, the replacement fuse

must be of the same type and amperage rating as

the original. Installing a fuse with a higher rating can

damage the system and could start a re.

PERSONAL SAFETY

• Remove ignition key and put the vehicle in park or

in gear to prevent others from starting the vehicle

during installation or service.

• Wear only snug-tting clothing while working on

your vehicle or sprayer system.

• Do not wear jewelry or a necktie, and secure long

hair.

• Wear safety goggles to protect your eyes from

brine, battery acid, gasoline, dirt, and dust.

• Do not eat, drink, smoke, rub your eyes, or touch

bare skin while spraying.

• Never point spray gun at people or animals.

• Avoid touching hot surfaces such as the engine,

radiator, hoses, and exhaust pipes.

• Always have a re extinguisher rated BC handy,

for ammable liquids and electrical res.

CAUTION

Disconnect electric and/or hydraulic power

and tag out if required before servicing or

performing maintenance.

SAFETY

TORQUE CHART

CAUTION

Read instructions before assembling.

Fasteners should be nger tight until

instructed to tighten according to the Torque

Chart. Use standard methods and practices

when installing equipment, including proper

personal protective safety equipment.

FIRE AND EXPLOSION

Be careful when using gasoline. Do not use gasoline

to clean parts. Store only in approved containers away

from sources of heat or ame.

CELL PHONES

A driver's rst responsibility is the safe operation of

the vehicle. The most important thing you can do

to prevent a crash is to avoid distractions and pay

attention to the road. Wait until it is safe to operate

Mobile Communication Equipment such as cell phones,

text messaging devices, pagers, or two-way radios.

VENTILATION

BATTERY SAFETY

WARNING

Gasoline is highly ammable and gasoline

vapor is explosive. Never smoke while

working on vehicle. Keep all open ames

away from gasoline tank and lines. Wipe up

any spilled gasoline immediately.

CAUTION

Batteries normally produce explosive gases

which can cause personal injury. Therefore,

do not allow ames, sparks, or lit tobacco

to come near the battery. When charging or

working near a battery, always cover your

face and protect your eyes, and also provide

ventilation.

• Batteries contain sulfuric acid, which burns

skin, eyes, and clothing.

• Disconnect the battery before removing or

replacing any electrical components.

WARNING

Vehicle exhaust contains lethal fumes.

Breathing these fumes, even in low

concentrations, can cause death. Never

operate a vehicle in an enclosed area without

venting exhaust to the outside.

2. Connect the hose underneath the unit: Securely

fasten the 90° elbow connection to the tank

bulkhead tting underneath the unit. Make sure

the bulkhead tting is securely fastened to the

tank to prevent leaks. Run the 2" hose from the

elbow to the shut-off valve below the pump. Clock

the 90° elbow so that the hose remains free

of kinks; cut it to length. Clamp the hose using

two (2) clamps on each end to prevent leaks. In

low temperatures, warming the hose may ease

installation. Dip the hose in hot water or carefully

use a heat gun for 20–40 seconds.

3. Connect the return valve to the 2" bulkhead

connection on the pump side of the brine tank.

Securely fasten the 45° connections to the tank

bulkhead tting and the return valve. Make sure

the bulkhead tting is securely fastened to the

tank to prevent leaks. Clock the 45° connections

so that the hose remains free of kinks, and cut

the 1-1/2" hose to length. Clamp the hose using

two (2) clamps on each end to prevent leaks.

4. Connect the bypass line to the 3/4" bulkhead

connection on the pump side of the brine tank.

Securely fasten the 90° elbow to the tank

bulkhead tting. Make sure the bulkhead tting

is securely fastened to the tank to prevent leaks.

Clock the 90° elbow so that the hose remains free

of kinks, and cut the 1/2" hose to length. Clamp

the hose tightly to prevent leaks.

INSTALLATION AND REMOVAL

NOTE: To prevent leaks, use a thread sealing

compound on all threaded connections. Do

not use Teon®tape, as fragments will clog the

spray nozzles. Clamped connections may require

periodic retightening.
