IMPORTANT SAFETY INFORMATION
Grounding Instructions
This machine must be grounded. If it should malfunction
or breakdown, grounding provides a path of least resis-
tance for electrical shock. This machine is equipped with
a cord having an equipment-grounding conductor and
grounding plug. The plug must be plugged into an appro-
priate outlet that is properly installed in accordance with
all local code and ordinances. Do not remove ground pin;
if missing, replace plug before use.
Improper installation of the equipment-grounding conduc-
tor can result in a risk of electric shock. Be sure to check
with a qualied electrician or service person if you are in
doubt as to whether the outlet is properly grounded. If
the plug will not t in the outlet do not modify either the
plug nor the machine’s cord, instead have a proper outlet
installed by a qualied technician.
This machine is for use on a nominal 120-volt circuit and
with a grounding plug similar to the one in Figure 1 below.
If a proper outlet is not available, follow the illustrations of
Figure 2 & 3 to install a temporary-grounding plug. This
temporary work-around should be used only until a proper
outlet (Figure 1) can be installed by a qualied electrician.
When and if this type of adapter is employed, screw the
adapter’s extended tab into place with a metal screw.
However, grounding adapters are not approved for use in
Canada.
Again, be sure to check the grounding pin for damages
and replace if necessary.
The Green, or Green-Yellow, wire in the cord is the
grounding wire. When replacing a plug, this wire must be
attached to only the grounding pin.
DO NOT use extension cords.
Please Note for America use only.
Parts and Service
Please contact a Mytee service personnel or Mytee
authorized Service Center using Mytee original replace-
ment parts and accessories for repairs are needing to be
performed. When and if calling Mytee for support, please
have your Model and Serial Number available for faster
assistance.
Name Plate
The Model and Serial Number are located on the lower
half of the back of the machine near the power plugs and
will be required for ordering replacement parts. You can
use the space provided on the front of this manual to note
down both for future referencing.
Unpacking the Machine
When your new machine is delivered, please carefully in-
spect both the shipping carton and the machine for dam-
ages. If damage is evident, save both the shipping carton

2 - MACHINE OPERATION
Vacuum & Solution Hoses
The Mytee Lite™ features a 2” Cu-Lynx™ vacuum hose
connection as well as a standard 1/4” quick disconnect
tting for solution hoses. ♦
2.3 - Filling the Solution Tank
The Mytee Lite™ solution tank can be lled up via the fau-
cet ll hose or from a bucket via the opening. ♦
2.1 - Powering the Mytee Lite™
To power the Mytee Lite™, plug the power cord into a
grounded 20 amp outlet. ♦
2.2 - Connecting Hoses & Cleaning Tools
New & Reconditioned Equipment & Parts - www.southeasternequipment.net

2 - MACHINE OPERATION
2.5 - Emptying the Solution & Recovery Tanks
The solution tank drain is located on the front, lower left
corner of the solution tank.
The recovery tank drain is located on the back of the
machine at the bottom of the recovery tank. Attach the
included recovery tank drain hose in order to easily empty
into a bucket or other receptacle. ♦
2.4 - Operating the Mytee Lite™
Switching On The Unit
In order to avoid vapor locking the unit, the Mytee Lite’s™
components should be switched on by following the pro-
cedure below:
1. Turn pump switch on.
2. Pull the lever on the cleaning tool to release air in the
line. Hold lever until a steady ow of water comes out of
the wand.
3. Once pump is primed and there is pressure in the solu-
tion line, turn on heater switch and wait a few minutes for
water to heat up.
4. Once water is heated, turn on vacuum and begin clean-
ing.
Note: When cleaning upholstery, always check manufac-
turer’s cleaning instructions.
Cleaning With The Mytee Lite™
For best results when extracting, do one wet pass followed
by two dry passes. This ensures you’re not over-soaking
the material and also gives the heater time to catch up.

3 - MACHINE MAINTENANCE
In order to keep the Mytee Lite™ running smoothly and
reduce the risk of damage to the machine and subsequent
downtime, Mytee recommends following the maintenance
schedule below:
Maintenance Item Daily Weekly
Clean and inspect tanks. X
Clean and inspect hoses. X
Check and clean internal lters. X
Check power supply cable. X
Clean machine with all-purpose
cleaner and cloth. X
Check spray nozzles. X
Flush solution system with Mytee
System Maintainer. X
Inspect vacuum hoses for holes and
loose cus. X
Inspect spray pattern for clogging.
If clogged, remove spray tips and
soak them in a recommended liquid
neutralizer for up to six hours. To re-
move spray tip, twist spray tip body
counter-clockwise.
X
Lubricate wheels with water resis-
tant oil. X
Inspect machine for water leaks and
loose hardware. X
3.1 - Filter Maintenance
The Mytee Lite™ has a small lter on the top of the vac-
uum stack in the recovery tank. This lter should be
checked and cleaned after each use. ♦
3.2 - System Maintainer
Weekly ushing of the solution system with Mytee®
System Maintainer helps keep lines clean and prevents
chemical build-up, improving pump life, performance and
pressure.
How to use System Maintainer:
1. Mix 1-quart 3601 System Maintainer with 1-quart of
warm water.
2. After thoroughly mixing, pour this solution into the solu-
tion tank.
3. Turn the pump on FIRST, and run solution through your
cleaning tool. NOTE: The jet should be removed from the
cleaning tool in order to prevent clogging due to loosening
of deposits in line.
4. Next, turn on the heater. If the heater is turned on rst,
it will result in a vapor lock, which will aect the machine’s
operation.
5. Next, with both the pump and heater on, begin running
the solution through the machine. This allows the solution
to break down any build up in the lines.
6. After running all of the solution through the machine, ll
the tank with clean, warm water. Run the water through the
machine to clear the solution completely out of the tank &
lines. ♦

5 - TROUBLESHOOTING
5.1 - Vacuum Troubleshooting
Vacuum is not turning on.
Possible Cause Solution
Vacuum may not be getting
power.
Check the electrical con-
nections and the switch.
Look for loose or damaged
wires.
To check the switch:
Unbolt the switch plate.
Take a picture of the layout
of the wires or tagging the
wires for future reference.
Switch the wires from the
vacuum switch with the
wires from either the pump
or heater switch. Turn on
the pump or heater switch
(whichever one you ex-
changed wires with). If the
vacuum turns on, then you
know the vacuum switch is
bad.
Vacuum is not producing suction.
Possible Causes Solutions
Recovery tank is full. Empty the recovery tank.
If the vacuum exhausts but
there is no suction, then
the hose from the recovery
tank to the vacuum motor
is disconnected.
Open the machine and nd
the hose running from the
recovery tank to the vacu-
um motor. Check if it is dis-
connected. If so, reconnect
it. If it has a leak, replace
the hose (Part # PH627 if
1.5”, PH628 if 2”).
Vacuum hose blockage
(if there is no suction or
exhaust).
Check for blockage in the
hose, starting from the
cleaning tool to the ma-
chine.
Clogged lter in vacuum
tank.
Clean out lter regularly.
Drain valve/cap is loose
and is causing air leakage.
Tighten the drain valve/cap.
Hose cus are loose and
causing air leakage.
Tighten all hose cus reg-
ularly as may loosen over
time. Use a glue to prevent
cus from coming loose
(optional).
Lid on tank is loose and is
causing air leakage.
Make sure the lid is tight.
Vacuum blows water out the exhaust.
Possible Causes Solutions
Foam building up in the
recovery tank.
Use a defoaming solution
in the recovery tank.
There is a loud grinding noise coming from the
vacuum.
Possible Cause Solution
Debris has been sucked
into the vacuum motor
chamber. Usually results
from dry vacuuming.
Replace the vacuum motor.
To avoid repeat problem,
DO NOT dry vacuum with
your extractor.

5 - TROUBLESHOOTING
5.2 - Pump Troubleshooting
Pump doesn’t turn on.
Possible Causes Solutions
Bad switch at control
panel.
Unbolt the switch plate.
We recommend taking a
picture of the layout of the
wires or tagging the wires
for future reference. Switch
the wires from the pump
switch with the wires from
either the vacuum or heater
switch. Turn on the vacuum
or heater switch (whichever
one you exchanged wires
with). If the pump turns on,
the pump switch is bad.
Loose or disconnected
wire.
Disconnect the power cord
from the electrical outlet.
Open up the machine and
look for any loose or dis-
connected wires. Re-at-
tach or replace wires.
Pump runs but there is no spray.
Possible Causes Solutions
Blockage or kink some-
where in the line.
See chart on page 4 of the
Diaphragm Pump Trouble-
shooting Guide to diagnose
the location of the block-
age.
Air is in the pump. Prime the pump.
Remove QD o the ma-
chine and solution hose.
Make sure that the three-
prong clip on the inside of
the threaded end is evenly
aligned below the thread of
the QD.
Pump runs but there is no spray.
Possible Causes Solutions
On a new unit, the check
valve between the pump
and heater may hang up,
causing the ow of water to
be impeded or stop entire-
ly.
Remove the check valve
temporarily and check to
see if the pump will ow
water out of the pump out-
let hose when the pump is
turned on for a brief instant
in order to verify cause.
The remedy is to install a
new check valve. Observe
the proper orientation (ow
direction) of the check
valve.
Tip: the check valve may
be able to be temporari-
ly returned to service by
un-sticking the check valve
poppet with manipulation
of the poppet ball with a
thin tool, like a straightened
paperclip. Replace the
check valve in unit assem-
bly.
NEVER OPERATE A UNIT
WITHOUT A CHECK
VALVE IN PLACE.
Pump runs for a second then shuts down.
Possible Causes Solutions
QD is pressure locked. Relieve pressure from be-
hind the QD by pressing in
the button inside the QD.
Low PSI.
Possible Causes Solutions
The jet nozzle could be too
large.
Replace the jet with one
that has a smaller opening.

5 - TROUBLESHOOTING
Pump doesn’t stop running.
Possible Causes Solutions
Leak somewhere in the
line.
Disconnect the solution
hose from the machine. If
this causes the pump to
stop running then the prob-
lem is outside the machine,
either in the solution hose
or tool. If it continues run-
ning on, open the machine
and check for leaks. Repair
the leak. If there are no
leaks, run Mytee’s System
Maintainer™ (Part # 3601)
through the machine to
clear blockages.
Cracks or vacuum leaks on
inlet side of pump.
Make sure hoses are
secured tightly. If the inlet
side of the pump is cracked
or damaged, replace the
pump.
Seals have been degraded
by chemical.
Install seal repair kit.
Debris blocking inlet lter
or pump head.
Clean lter and/or pump
head.
Pump trips circuit breaker when turned on.
Possible Causes Solutions
Short in power switch. Test by swapping vacuum
and pump switch. If prob-
lem resolves, but vacuum
begins tripping breaker, re-
place switch (Part #E515).
Short in electrical harness. Risk of electric shock. Do
this at your own risk.
Remove pump from circuit
by attaching power leads
together. If breaker still
pops when switch is tog-
gled, then there is a short
to the ground in the circuit.
Replace wires as needed.
Short in pump motor. If switch and harness
check is OK, the short
may be in the pump motor.
Replace pump.

5.3 - Heater Troubleshooting
Heater is not heating water.
Possible Causes Solutions
Loose electrical connec-
tion.
Check all electrical con-
nections, including power
cord and harness.
Automatic sensor has
failed, causing manual
sensor to trip.
Reset the manual sensor
button by pressing the
small white and yellow
button in the center of the
sensor. If this works, but
heater continues to trip the
manual sensor, replace
the automatic sensor (Part
#E573) on the heater.
Heater element has failed. Check for continuity
through the element by
reading the amperage. If
amps are low, only part of
the element may be heat-
ing up – in this case, the
element is damaged and
needs to be replaced.
Bad power switch. If the element, sensors,
and wiring all check out
okay, there may be a bad
switch on the switch-plate.

5 - TROUBLESHOOTING
Running out of hot water too fast.
Possible Causes Solutions
Too much water owing
through the heater.
Remember, when using
your machine, it is rec-
ommended you do one
wet pass followed by two
dry passes. This way you
are not spraying as much
and the hot water will last
longer.
Jets being used are too
large.
If your machine has a
1,000W or 1,200W heating
system, make sure your
cleaning tool has 0.02 jets.
Water in tank is very cold. If possible, ll your solu-
tion tank with warm water
in order to shorten the
amount of time it takes for
the water to heat up. The
pumps are usually rated for
140°F water.
Heater has hard water
buildup inside, leading to
lost eciency.
Run Mytee System Main-
tainer™ (Part # 3601)
through the machine regu-
larly in order to clear hard
water or chemical residue
that can block water ow
and reduce heating abil-
ity. See product label for
instructions.
Unit has vapor locked and there is no water pumping
out of the unit.
Possible Cause Solution
Turning on the heater
before turning on the pump
and priming the unit.
Turn o the heater and
allow the unit to cool com-
pletely. When machine has
cooled, turn on the pump
rst. Prime the unit by
spraying solution out of the
cleaning tool. Then, turn on
the heater.
