ASSEMBLY AND INSTALLATION
GROUND FAULT CIRCUIT INTERRUPTER (GFCI) PROTECTION
This pressure washer is provided with a ground fault circuit interrupter (GFCI) built into the plug of the power supply cord. This device
provides additional protection from the risk of electric shock. Should replacement of the plug or cord become necessary, use only
identical replacement parts that include GFCI protection. Replace compete GFCI cord assembly if either the GFCI, plug or cord is
damaged, frayed or worn.
GROUNDING
This product must be grounded. If it should malfunction or
break down, grounding provides a path of least resistance
for electric current to reduce the risk of electric shock. This
product is equipped with a cord having an equipment-
grounding conductor and a grounding plug. The plug must
be plugged into an appropriate outlet that is properly
installed and grounded in accordance with all local codes and
ordinances.
DANGER - Improper connection of the equipment-grounding
conductor can result in a risk of electrocution. Check with a
qualied electrician or service personnel if you are in doubt
as to whether the outlet is properly grounded. Do not modify
the plug provided with the product; if it will not t the outlet,
have a proper outlet installed by a qualied electrician. Do
not use any type of adaptor with this product.
EXTENSION CORDS
Use only 3-wire extension cords that have 3-prong grounding-type
plugs and 3-pole cord connectors that accept the plug from the
product. Use only extension cords that are intended for outdoor
use. These extension cords are identied by a marking "Acceptable
for use with outdoor appliances; store indoors while not in use." Use
only extension cords having an electrical rating not less than the

Planning The Installation
Prior to beginning the installation, thoroughly consider where the unit will be located, access to utilities and tool requirements for the
job. These considerations will help to ensure the unit is properly installed in the best location with minimal diculty.
Location - Safety and convenience during use and servicing of the equipment should be a primary concern in determining the
specic location of the SMT wall-mounted cleaning system.
Accessibility - A readily accessible unit will ensure that the cleaning will be done regularly and with less eort. Accessibility will also
provide convenience when servicing becomes necessary. Avoid installing the unit in a location that will become inaccessible.
Clearances - Adequate clearance overhead and on both sides is important. Fourteen-inch overhead clearance is required to remove
the stainless steel cover. Ten-inch clearance is required on each side to remove the cover mounting hardware. Units equipped with
a wall-mounted hose reel will require additional clearance on the right side for manually rewinding the hose.
Structural support - A fully assembled SMT wall-mount unit weights approximately 100 pounds. It is important for personal and
equipment safety that the unit is securely fastened to a wall that will sustain this weight. Walls with metal framing should include
backing for mounting the SMT unit.
Safety - The unit should be mounted on the wall at a height that does not present a hazard of being struck by personnel or
interfering with the ow of trac in the area in which the unit is installed.
Electrical - The SMT unit is equipped with a 4-foot long power cord. The unit or the power receptacle should be positioned such
that the power cord can be easily connected to the receptacle with minimal strain on the cord. The power receptacle should be
located above the SMT unit away from risk of exposure to water.
Water - The SMT unit is equipped with a 6-foot water supply hose. The unit or the hose bib should be positioned such that the
supply hose can be easily connected with minimal stress on the hose.
Noise - As with all pressure washers, the SMT unit will make noise during operation. Avoid locating the unit in or adjoining any area
that is noise sensitive.
Chemical Supply - The SMT unit can draw chemical from a 1-gallon bottle mounted on the wall or a 55-gallon drum. Ensure
adequate chemical storage space if chemical(s) will be drawn from a large container.
WARNING:
Unit is to be installed in a location designed for wet applications with an operable and adequate drain. If installation in such a
location is not possible, turn o the incoming water supply to the unit when unattended or not in use to minimize the possibility of
leaks and potential water damage.

Hardware and Tool Requirements
Mounting hardware - Hardware for mounting to wood studs is included with your unit. This hardware may not be suitable for
many other type walls. Do not use hardware that is inadequate for your installation application.
Tools and supplies - No special tools are required. Installation of this unit can be done with tools that are common to the average
service technician’s toolbox or are available at your local hardware store. Installation of the pump unit will be made easier and
safer with the use of two 24-inch 2-by-4’s. These 2-by-4’s will be laid across the wall-mount brackets to support the pump during
installation of vibration dampening mounts.
Utilities
Electrical - Verify the dedicated circuit Voltage is correct for the Voltage of the unit being installed. Make sure the unit ON/OFF
switch is set to“OFF" prior to connecting the unit to the power receptacle.
Water pressure and ow rate - The water supply to the unit must have a ow rate of at least 5 GPM at a pressure of 30 PSI. Anything
less may cause intermittent shutdown of the system.
Water temperature - Water supply temperatures in excess of 120° F will cause the unit to shut down to protect the pump seals from
damage. SMT recommends a water supply temperature of 120° F or less.

Installation Procedure (continued)
Refer to Figure 3 and Figure 4 for installation of the SMT-1100W. The SMT-1100W installation is similar to the installation of the
SMT-600W. Dierences in the installation are easily recognizable and should present little diculty in adapting the instructions for
the SMT-600W to the installation of the SMT-1100W.
Brackets, Hose Reel & Hose
Installation
Wall-mount brackets and
hose reel - Brackets must be
installed on 16-inch centers
to align with the mounting
holes in the frame of the
pump and hose reel. Locate
the mounting-holes for the
brackets on the wall using
the template provided as
part of the shipping carton.
Install the two wall-mount
brackets with appropriate
hardware. If a wall-mount
hose reel is to be installed
with the pump unit it will
be attached with the same
hardware that attaches the
lower part of the wall-mount
brackets. Attach the brackets
to the wall with the top hole
in the bracket, and then
attach the hose reel to the
lower part of the brackets.
Install the hose reel and brackets together.
High-pressure hose - Install the high-pressure hose on the hose reel by inserting the threaded end of the hose through the hole in
the ange of the reel and tighten into the tting on the handle side of the reel. Wrap the threads of the tting with several wraps of
Teon tape. Secure the hose to the reel ange with the two rubber-coated clamps on the reel.
Main Pump Installation
Vibration/shock-mount: Install four shock-mount pads onto the wall mount brackets following the directions in the instruction
sheet provided with the hardware kit. Loosely install the nuts on the shock-mounts on the underside of the brackets. These will be
wrench tightened after the pump is secured to the brackets.
Pump: Remove the stainless steel cover from the pump.
• Place two 2-by-4’s across the two previously installed wall-mount brackets between and contacting the shock-mounts. Place
the pump on the 2-by-4’s, centered over the wall-mount brackets, with the blue tank to the left rear. Position the pump frame
to align the holes in the bottom of the frame with the shock-mounts. Screw the shock-mounts up into the frame 1/2 turn past
contact between the frame and the rubber.
• Remove the 2-by-4’s and lower the weight of the pump unit onto the shock-mounts.
• Tighten the nuts on the bottom of the shock-mounts until the shock-mounts just begin to bulge, and then tighten one full turn.
• Remove the straps holding hoses and power cords during shipment. Extend hoses and power cord behind and below the pump.
• Remove the black oil ll shipping cap from the top of the pump and replace with the red vent cap attached to the pump head.
Verify that the oil level in the pump is at the red dot on the oil level sight-glass. Water supply hose: Connect the 6-foot braided
water supply hose to the oat valve. Connection is made at the underside of the pump frame-plate, beneath the blue oat
tank, to the threaded ball-cock tting. DO NOT OVER-TIGHTEN. Over-tightening will twist the oat valve in the tank causing
the oat to bind against the side of the tank. The supply end of the water supply hose will be connected to the water lter after
it is installed. 7

Main Pump Installation (continued)
Hose reel connection: If equipped with a hose reel, route the high-pressure pump hose behind the unit and connect to the tting
on the hose reel swivel. Use several wraps of Teon tape on threaded tting.
GFCI power cord: Route the GFCI power cord out the back of the pump unit and connect it to the dedicated power receptacle.
Cover installation
• Install the four cover mounting screws into the side of the frame just far enough to support the cover while the cover is positioned
into place.
• Position the cover over the unit taking care not to damage the chemical metering knobs or the ON/OFF switch.
• Remove the two rear cover mount screws and lower the cover into position then replace the screws through the holes in the cover.
• Remove the two front cover mount screws and lower the cover into position then replace the screws through the holes in the cover.
Ensure that the large washer inside the cover captures the top of the chemical selector mount bracket.
Accessory Installation
Water lter: Install the water lter assembly on the wall within reach of the 6-foot hoses to the pump and the water supply hose bib.
Connect the braided hose from the pump to the lter tting labeled "OUT". Connect the hose supplied with the lter to the hose
bib and to the lter tting labeled "IN".
Chemical baskets: Install the chemical baskets below or beside the pump unit within reach of the chemical pickup tubes. Locating
the chemical supply at or near pump level will enhance the chemical control function.
Spray gun hanger: Attach the spray gun hanger to the side of the wall-mount bracket at a convenient location using the self-
drilling/self-tapping screws provided with the gun hanger.
Functional Test
Functional test the unit upon completion of the pump installation, to ensure that it has been installed properly and that there are
no leaks or malfunctions. NOTE: Set the ON/OFF switch to the "OFF" position before connecting the power cord to the receptacle.
Ensure the water supply hose is connected to the water supply bibb and the hose bibb valve is fully open.
Circuit Breaker (main): Set the circuit breaker in the main panel to the on position.
GFCI: Connect the unit GFCI power cord to the dedicated receptacle and press the "RESET" button on the GFCI. Press the "TEST" button
on the GFCI and verify that the GFCI trips to interrupt power to the unit. Press the "RESET" button and verify that the GFCI resets.
Hoses and spray gun: The hose may be permanently attached to the wall-mounted hose reel or connected by a quick disconnect
tting on the front underside of the pump unit. Connect the spray gun to the end of the hose. Direct the spray gun away from
persons or objects and ensure the trigger is in the released position prior to turning the machine ON.
ON/OFF: Grasp the spray gun rmly and set the ON/OFF switch to "ON". The pump should be heard
to operate. The pressure gauge will momentarily show a high-pressure spike and then drop back to
near zero PSI. The pump will only show pressure on the gauge when the spray gun is in operation.
Low/high-pressure: Position the spray gun to operate it on low-pressure and squeeze the spray
gun trigger. Note that the output is a low-pressure stream and that the pressure gauge indicates a
pressure near or below 400 PSI. Position the spray gun to operate it on high-pressure and squeeze
the spray gun trigger. Note that the output is a high-pressure stream and that the pressure gauge
indicates a pressure approximately 50 PSI below the pressure shown on the Maximum Pressure
label on the front of the pump.
Chemical injection: While operating the spray gun on low pressure, set the chemical selector
valve to select one of the chemicals. Note that chemical is drawn up the chemical pick-up tubes
and is dispensed with the low-pressure output. Several seconds may be required for the chemical
to appear at the output. Repeat for the second chemical selector if so equipped. Adjust both
chemical selectors to FLUSH and operate the spray gun on low pressure until the spray output is
free of chemical. Set both chemical selectors to "OFF". Set the ON/OFF switch to "OFF". Squeeze
the spray gun trigger to release pressure. Disconnect and store all equipment.

Assembly and Installation

User Operated Controls
ON/OFF Switch: The Power ON/OFF switch is used to turn the pump motor on and o as necessary for operation. The ON/OFF switch
is located on the upper right corner of the SMT-600-W cover. The SMT-1100-W ON/OFF switch is located just under the cover on the
left side of the unit.
Gun: The spray gun assembly provides operator control of the ow, pressure and pattern of the high-pressure spray. The spray gun
is connected to the output end of the high-pressure hose by quick-connect ttings. Squeezing the gun trigger while directing the
spray nozzle toward the surface or equipment to be cleaned operates the spray gun. Your spray gun may be equipped with a dual
nozzle or a vari-nozzle.
Dual Nozzle: The dual nozzle selector is used
to select either the low-pressure "soap" nozzle
or the high-pressure "rinse" nozzle. Selection of
the desired nozzle must be made while the spray
gun trigger is released. To select the low-pressure
nozzle, rotate the spray gun 90° counter-clockwise
so that the spray gun handle is parallel to the
ground with the hose connection extending to
the operators right, then squeeze the trigger. To
select the high-pressure nozzle, rotate the spray
gun 90° clockwise so that the spray gun handle
is parallel to the ground with the hose extending
to the operator’s left, then squeeze the spray
gun trigger. Once the nozzle has been selected
and the spray gun trigger held open, the spray
gun may be rotated and aimed in any direction
without aecting pressure nozzle selection.
Vari-Nozzle: The vari-nozzle is used to select
either low-pressure "soap" or high-pressure
"rinse", and to adjust the spray-pattern from a
wide-angle spray to a zero degree stream. Moving
the black body of the nozzle toward or away from
the gun handle respectively makes selection of
high or low pressure. For high-pressure, pull the
black nozzle-body rmly toward the spray-gun
handle. To select low-pressure, push the black
nozzle-body rmly away from the spray-gun
handle. To vary the spray-pattern of the nozzle,
twist the black nozzle-body for the desired spray-
pattern.
Chemical Metering Selectors (600 series): This
control allows the operator to select a chemical
to be injected and meter it into the low-pressure
spray. It also provides a means to ush the
chemical injector after each use. The Chemical
Metering Selector is located on the lower left front corner of the SMT-600-W cover. This control is optional on the SMT-1100-W and
is located on the upper right corner of the cover when so equipped. Turning the selector knob from the "OFF" position counter-
clockwise selects and meters the chemical. The farther the control knob is turned, the higher the chemical concentration out the
spray gun. See the chemical dilution chart and instructions on the back page of this manual. To ush the chemical injector, turn the
metering knob fully clockwise and operate the spray gun and pump on low pressure for one minute.
Chemical Metering Knob (SMT-1100-W): The Chemical Metering Knob is located on the chemical injector and is used to set the
chemical concentration in the spray output. The chemical metering knob has a graduated scale that is used for reference setting
only. Turn the metering knob fully clockwise for NO chemical. Turn the metering knob counter-clockwise to increase the chemical
concentration to the desired strength. See the chemical dilution chart on the back page of this manual.

Maintenance
Oil: Add oil to the pump reservoir as necessary to keep the oil
level at the center of the red dot on the oil-level sight glass. Check
oil level with machine "OFF". Change initial oil ll after 50 hours
running period. Thereafter, change oil every 3 months or 500
hours of operation. Use ISO-68 non detergent hydraulic oil only.
Use of any other type oil will void the warranty and may damage
the pump. Oil may be purchased from Spray Master Technologies®
by calling [phone] or [phone].
Water Supply Filter: A quality water supply lter is essential to
pump life longevity. Do not operate your pump without a water
supply lter. Replace the 5 micron water supply lter every 3
months or as needed to ensure an adequate supply of clean
water to the pump. A dirty lter can restrict water ow and cause
intermittent shutdown of the pump.
Chemical Foot Screen: Flush the chemical foot screens and
injector with warm water to remove chemical buildup that can
restrict chemical ow. Remove the chemical pickup tube and
foot-screen from the chemical supply and submerse it in warm
water. Operate the system on low-pressure for 2 minutes with the
chemical control set to maximum
Hard Water Deposit: Flush the pump with a de-liming agent, such
as Lime-A-Way, as often as necessary to keep the system free of
mineral buildup that can adversely aect operation. Pour 8 ounces
of de-liming agent into the full oat tank. With the spray gun
connected and closed, turn the pump "ON" and allow recirculation
for 5 minutes. After recirculation, direct the spray gun output into
a drain for several minutes to purge the de-liming agent from the
system.
Moving: SMT Wall-Mount units are stationary units that are installed on wall-mounted brackets. Once installed, it is impractical to
move the pump for use in various locations.
Stationary units are heavy and care should be taken during installation to use proper handling techniques, including two-man lifting.
Storage:Store SMT equipment and accessories so that they do not present a tripping or falling hazard. Protect from freezing. When
storing SMT pressure cleaning units for extended periods or in freezing conditions, drain all water and winterize the system with
antifreeze for use in potable water systems.
Caution: If your system is used to clean food-processing equipment, consult your chemical supplier for
antifreeze that is suitable for that application.
Winterize your SMT system as follows.
Turn o the water supply and disconnect the water supply hose from the unit.
• Run the unit with the spray gun open until the tank is empty.

Chemical Metering Instructions
Chemical Dilution Chart & Instructions
Ounces of Chemical Per Gallon of Water
To calculate and adjust the chemical dilution for a Spray Master Technologies Cleaning System, follow the steps below.
Step 1 Find your pump GPM rating on the left side of the chart
Step 2 Follow the row identied in step #1 to the right until you nd the column heading with the chemical manufacturer’s
recommended ounces per gallon to be injected into the water.
Step 3 The value at the point where the row (step 1) and the column (step 2) intersect is the ounces of chemical that should be
injected into the SMT system during one minute to achieve the manufacturer’s recommended chemical solution strength.
Example a 2.9 gallon per minute (GPM) pump used to apply a chemical requiring a mix ratio of 4 ounces
per gallon will need to inject 11 3/5 ounces of chemical during a period of one minute.
Step 4 Fill a measuring cup (graduated in ounces) with the chemical to be injected and submerge the chemical pick-up tube with
foot screen in the chemical.
Step 5 Turn the pump on and set it to inject chemical.
Step 6. Adjust the chemical metering device so that the ounces of chemical calculated in step 3 above is drawn from the measuring
cup during a period of one minute. (The adjustment can also be made injecting half the chemical in half a minute)
Note: check chemical metering regularly to ensure accurate chemical dispensing.
