Installation and Operation Manual |MTI 526, 527P/S, & 527W 3
Unpacking
You will need the following to unpack and assemble
your new MTI chair:
t Wire or sheet metal cutters to cut banding
t A medium size Phillips screw driver for installation
of the patient arm upholstery
t 7/16” open or closed box end wrench (also a 5/8”
open or closed wrench and set of allyn wrenches, if
a light post is ordered)
t A utility knife or blade to open the upholstery box
t A medium at blade screw driver
t A pair of needle nosed pliers can also be helpful
1. Open the upholstery box using the utility knife
with the blade only slightly exposed so the
upholstery does not get damaged while cutting
the tape. Inspect the upholstery carefully for any
damage. There should be; (2) upholstered arms,
(1) upholstered back cushion, (1) upholstered
seat cushion, (1) upholstered foot cushion with
scu cover, and (1) upholstery ap, which will go
between the seat and back cushions.
2. Cut the banding on the chair pallet lid and remove
the corrugated box, being careful not to scrape the
chair inside.
3. Using the 7/16” wrench or an adjustable wrench to
loosen the four nuts and remove, along with the
wooden slats holding the base to the wood pallet.
This equipment is heavy, get help to remove it from
the shipping pallet. Use proper lifting procedures when
lifting to avoid serious back injury. Lift the chair from the
retracted foot section and from the exposed male back
clevis protruding from the chair back as it lays over the
seat. Scoot or slide the base to the oor from the pallet.
Avoid lifting from the formed plastic side panels or
foot section levers, as damage to them may result. If the
installation location is on a vinyl or hard tile oor, a piece
of carpet or other material should be placed beside the
pallet to act as a cushion to protect the ooring.
Allow the chair to come to room temperature to
get maximum performance. Prolonged storage at low
temperatures can make the operation slow or even not
function until the motors have warmed up.
4. Remove the foot control from its corrugated
enclosure.
5. The chair is shipped with the back section laying
over on the seat. Grasp the end of the back motor
push tube, while at the same time, cut the cable
tie attaching it to the back actuator levers located
on the bottom lower left side of the chair back.
Remove one of the e-ring fasteners from the
precision pin located in the holes of the back
actuator levers. Raise the back up to approximately
70 degrees vertical to the oor. Align the holes in
the back actuator push tube with the holes in the
actuator levers of the chair back. (Figure 1). Push
the pin through the holes and replace the e-ring.
A hard rubber mallet may be necessary to replace
the pin.
Figure 1

4 Installation and Operation Manual |MTI 526, 527P/S, & 527W
Be extremely careful in this next step of installing the
arm linkage pin, that you do not drop the pin or e-ring
inside the base or you will have to disassemble the covers
to retrieve them.
6. Remove the e-ring and pin from the arm
actuation linkage. With your left hand, or by using
someone to assist you, raise the left patient arm
approximately horizontal. With your right hand pull
the plastic top cover edge outward slightly, and
at the same time, align the pin with the holes in
linkage. Some wiggling up and down of the arm,
while pressing the pin inward may be needed
(Figure 2). After pin is all the way through the
holes, replace the remaining e-ring.
Figure 2
7. Align pins and tabs of the male foot control plug
with the chair receptacle by positioning the
yellow/white mark on the plug body to the twelve
O’clock position relative to the receptacle at the
lower rear of the chair base (Figure 3). Secure the
plug body by rotating the locking ring clockwise
(CW) until it engages and then stops.
Figure 3
Alignment only requires slight pressure; do not force
the male plug into the female receptacle of the base as
damage to one or both plugs can occur.
8. Your MTI chair is equipped with a separate three-
wire electrical supply cord, with a grounded male
plug cap and an IEC320 female plug to the chair. To
install, plug the IEC320 female plug into the chair
and secure with the spring wire keeper (Figure 4).
Then plug the grounded male plug cap and attach
the surge protector to an appropriately protected
115/60 or 230/50 Volt AC grounded outlet. The
AC (alternating current) input is transformed to 24
volts and then rectied to DC (direct current) just
after the power enters the
chair base.
Figure 4

Installation and Operation Manual |MTI 526, 527P/S, & 527W 5
Each MTI chair has a circuit board. The included surge
protector must be used to protect the board. Warranty is
void if this surge protector is not used.
Do not use a two-three plug adapter to plug the MTI
chair into a two conductor outlet, as grounding reliability
is not then maintained.
Do not operate your MTI chair in the presence of
ammable anesthetics.
The supply cord may be used to simultaneously
insolate both poles of the power supply by removing the
power supply cord at the chair input or wall receptacle.
The electro magnet on any optional electro
magnetically operated swivel base has been evaluated for
potential electro magnetic interference and health risks
and found NOT to present any potential problems.
Leveling Feet Adjustments
In order to keep the table’s base level on any type of
surface, your MTI table is equipped with leveling feet
on each corner of the chair base plate.
If you chair is not level or it rocks from side to side, then
adjustement to one or more of the leveling feel will be
required.
1. Position the table where it will be intended to be
used. Check the stability of the table by wiggling
the table top from side to side with the table in the
fully raised position.
2. Use a 5/8” open or closed end wrench to loosen
and remove the plated acorn nuts which are found
on the corners of the base plate (Figure 5).
Figure 5
3. Using a medium at blade screwdriver, turn the
slotted screw under the acorn nut clockwise
(CW) to take up more space under the plate or
counterclockwise (CCW) for less travel (Figure 6).
Figure 6
Adjustments to one or more of the leveling feet may
be needed to be done for optimal results.
Upholstery Installation
Your upholstery kit includes the following upholstery
pieces:
t Back cushion upholstery
t Seat cushion upholstery
t Foot cushion upholstery

6 Installation and Operation Manual |MTI 526, 527P/S, & 527W
t (2) Upholstered arms that come with (8) 10-24 x 1

If your MTI table is ordered with optional arms,
headrests, lights, etc., those parts will be in a separate box
from the upholstery.
All cushions and the foot cushion scu cover attach to
the chair with Velcro® for easy installation and removal.
While installing all cushions, align Velcro® strips and
cushions with the mating Velcro® strips on the chair
metal section substrates.
4. Power the metal back down to a position in the same
plain as the seat. Install the ap between the seat and
back cushions rst, by laying the ap over the chair
back hinges and securing the ap to the Velcro® strips
of the back and seat cushions (Figure 7).
Figure 7
5. Install the seat cushion by placing the rear of the
cushion rst against the hinges located at the rear
of the seat and then lowering it to the front of
the seat, while aligning the waterfall edges of the
cushion with the formed recesses of the side panel
moldings (Figure 8).
Figure 8
6. Resting the top of the back cushion on the top of
the formed back cushion cover, match the waterfall
cushion to the formed recess of the thermoformed

or “home”position.
“Position”buttons (527S & 527WS models only) –
when pressed the lift function and tilt function operate
in the “up” position at the same time for more rapid
patient positioning.
When operating the “position “ function on the corded
hand control, be sure to place the thumb or index nger
over the middle of the raised green button and press rmly.
The operator is actually pressing two separate electrical
circuits at the same time.

8 Installation and Operation Manual |MTI 526, 527P/S, & 527W
OPERATION
If the chair is unplugged, press the auto return and
bring the chair back into the full home position before
using programmability.
Your new MTI chair is equipped with extremely high
quality low voltage DC motors that are rated at a 10%
duty cycle, which is similar to other motors. Motor damage
will result with excessive motor operation. This duty cycle
means one minute on and nine minutes o.
Model 526 Foot/Hand Controls
The foot/hand controls for your MTI Model 526 chair
with programmable positioning are power back, tilt,
auto return, and stop. The operator places their foot/
nger in the middle of the pedal/button and rocks
from side to side on the pedal or a rm direct push on
the hand control button in the direction of the arrow
for each individual function.
The “Return/Home” button is used to automatically
return the chair from any position to the full upright
chair (exit) position. The “Stop”button will cancel the
return or programmable command at any time. In
addition, touching any function pedal in any direction
will also cancel the return or programmable command.
More than one pedal may be actuated simultaneously
except a combination of the tilt down and either lift up
or down (Figure 12).
Figure 12
Model 527S & 527WS Foot/Hand
Controls
The foot/hand controls for your MTI Model 527S chair
with programmable positioning are power lift, back,
tilt, auto return, stop, and position. The “Position” switch
is a quasi programming feature that operates both the
lift and the tilt functions simultaneously for more rapid
positioning of the patient. When the “Position” button is
released, all chair movement stops.
Once the patient reaches an average position, ne
adjustment of either function can be made with the
manual pedals/buttons, if needed (Figure 13).
Figure 13

Installation and Operation Manual |MTI 526, 527P/S, & 527W 9
Model 527P & 527WP “Programmable”
Power Base Chair
The foot/hand controls for your MTI Model 527P chair
with programmable positioning are power lift, back,
tilt, auto return, stop, enter and Prg. 1 & 2. There are
two additional program positions on the hand control
version of the 527P and 527WP (Figure 14). Depress
the auto return button and let the chair return to the
exit position. To program your chair, the operator places
their foot/nger in the middle of the pedal/button
and rock from side to side on the pedal or a rm direct
push on the hand control button in the direction of the
arrow for each individual function. When the chair is in
the desired memory location, depress the enter button
and then either the Prg. 1 or 2 (3 or 4) to memorize that
particular position. The chair may be driven from Prg. 1
to Prg. 2, 3, or 4, manually adjusted during procedure
and then returned to either preset or returned. New
positions can be programmed in at anytime.
Figure 14
The Programmer has permanent memory and recalls
any program position previously entered. Upon initial
installation, it is recommended that each program switch
be programmed so that it is known what the chair will do
when a program switch is activated.
When chair is in motion from a programmable
position or auto return, injury may occur if chair is not
attended to until it comes to a complete stop.
Again, the “Return”button is used to automatically
return the chair from any position to the full upright
chair (exit) position.
Electrical Lock-Out
Because your new MTI chair has electronic
components, it can be interfered with by lightening
and possible EMI (electro magnetic interference)
and RFI (radio frequency interference), a total system
lock-out has been installed. To completely block all
interference with the chair from all outside sources,
move the toggle switch located on the lower right
corner of the base cover to the “OFF” position. With the
switch in the “OFF” position no movement is possible
(Figure 15).
Figure 15
Swivel Base Installation
If your MTI Surgery Table is equipped with a swivel
base, please follow these instructions. Move to the
rear of the chair base (patients head end). Remove the
9/16” hex bolt, (Figure 16), which locates and stabilizes
the swivel plate to the base plate. Depending on
the model of chair or table, the foot control may be
connected to the foot or head end of the chair.

10 Installation and Operation Manual |MTI 526, 527P/S, & 527W
Figure 16
Swivel Base Operation
The push button on the top side of the foot switch
controls the low voltage signal to the swivel brake
mechanism (Figure 17). The swivel brake is electro
magnetic. Depression of the “Swivel” button located on
the upper right of the foot control or the upper right of
the hand control will cause the swivel brake to release
for a period of approximately in (6) seconds, giving
time to rotate the chair. After the six second delay, the
swivel brake will automatically actuate. If needed, the
swivel button can be pressed within the six second
time frame to actuate the swivel manually. There is
a “clunk” or “clank” noise as the magnet is energized,
which is entirely normal. The swivel is always on.
Figure 17
Foot Section Adjustment
The foot section on your new MTI chair was designed
to allow for almost innite adjustability over the nearly
12 inches of its extension. This adjustment is controlled
by a lever with the black ball knob located at the front
of the foot section on either side (Figure 18).
Do not lift the handle up, only downward movement
will unlock the foot section. Lifting upward on the handle
will damage it.
Do not press the lock handle more than necessary
to unlock it, as spring damage will result. Only slight
downward depression of the handle is required to move
the foot section.
Foot section is rated at a maximum of 200 lbs.
extended.
To extend or retract the foot section, grasp either of
the foot section lock levers with one hand and the foot
section with the other and at the same time, push the
lever downward to disengage the lock. Move the foot
section to the desired location and release the lever.
The lock lever engagement tabs will mate with the
slots of the locking ladder located on the underside of
the foot section support and prevent any unwanted
movement. A slight wiggling motion of the foot
section on one side or the other may be needed to
assure good locking tab/lock ladder engagement.
Figure 18

Installation and Operation Manual |MTI 526, 527P/S, & 527W 11
Always return the foot section to the “closed” position
BEFORE allowing the patient to exit the chair to avoid
possible injury to patient or damage to the chair. Never
allow the patient to sit on the end of the foot section,
especially while it is extended.
Debris Tray Tension Adjustment
The debris tray on your MTI chair was designed to
allow innite positioning throughout its approximate
12 inch extension. Tray location is controlled entirely
by the friction provided by two green urethane pads
located between the at underneath side of the metal
foot section upholstery substrate and the top of the
debris tray pan. The urethane pads are spring loaded.
The amount of “drag”from these pads can be adjusted
by rotation of the brake spring nut, located just under
the brake spring. Using a 3/8” open end wrench, rotate
the nut counter clockwise (CCW) to increase drag and
clockwise (CW) to reduce drag (Figure 19).
Figure 19
All surfaces of the foot section must be cleaned
regularly to assure the slides, upholstery/scu cover, and
metal frame do not rust or corrode from liquids.
Failure to return the debris tray or foot section to their
stored position and/or clear any obstruction such as stools,
etc. before the chair is put into auto return, could cause
equipment damage or personal injury.
Retractable Arms
To Retract Arms grasp the black tab lever lock with
your index or middle nger, pull up slightly and release
while sliding the upholstered arm backward until it
stops and again locks (Figure 20).
To Close and Lock Arms reverse the procedure by
grasping the black tab lever lock with your index or
middle nger, pull up slightly and release while sliding the
upholstered arm forward until it stops and again locks.
Figure 20
Optional Duplex Electrical Outlet
Your MTI chair can be provided with a duplex 115 volt
electrical outlet. The outlet can be mounted on either
side of the chair on the seat side panel. The outlet should
be installed by a qualied service person. This outlet is
protected by the main chair fuses located at the bottom
rear of the chair base in the female IEC plug body. If the
outlet is to be installed on a 115 volt model only, the two
4 amp slo-blow glass fuses must be replaced by two 10
amp slo-blow glass fuses. See Fuse Replacement*.
Be sure not to exceed the cumulative amperage rating
of these plugs and the chair.
Do not use a two-three adaptor to plug any accessory
into either of these auxiliary outlets.

12 Installation and Operation Manual |MTI 526, 527P/S, & 527W
CLEANING & DISINFECTION
Upholstery
The upholstery used to cover your new MTI chair is
medical grade and has been manufactured to be
resistant to many types of uids and stains; however, it
can be damaged by some dyes and solvents as well as
sharp or pointed objects.
Avoid contact with sharp or pointed objects. Do not
place hard surface objects on the cushions surfaces as
temporary indentations or impressions in the upholstery
cover will result. Prolonged contact with a hard or irregular
shaped object may make the impression semi permanent.
Should anything be spilled or otherwise applied to the
upholstery surface, it should immediately be wiped
up, and at an appropriate time, cleaned using a quality
grade of vinyl cleaner, such as Spartan #SD-20 or a mild
soap and water solution. A weekly cleaning with these
same cleaners will keep the upholstery of your new MTI
chair looking new for years to come.
If disinfection is required, dampen a soft white
cloth with a solution of household bleach (sodium
hypochlorite); 10% bleach, 90% water. Rub gently.
Rinse with a water dampened cloth, or wiped on to the
metal surfaces of the chair, which are likely to come
into contact with the patient or operator. Follow the
manufacture’s instructions for dilution and additional
application techniques.
Any sprayed disinfectant or cleaning solution should
be wiped up immediately after application. A small sample
area should be tested before any large application on any
cleaner/disinfectant.
Painted Surfaces
All painted metal parts have been electro statically
painted and the paint is baked on for durability. Weekly,
those surfaces should be wiped down with a quality
grade cleaner and a soft cloth or a damp cloth with
mild soap.
Plastic Components
Any plastic component such as the chair back cover or
base cover should be cleaned regularly with a quality
grade of plastic cleaner and a soft cloth or a damp
cloth with mild soap. Avoid prolonged direct sunlight
exposure to preclude color change of the plastic.
The same disinfecting procedure can be followed for
painted or plastic parts as that for the upholstery.
MAINTENANCE
All moving parts of this chair should be inspected
annually by a qualied service technician. Any moving
joints and pins should be lubricated every 2-4 years
with a high quality grade white grease like Lubriplate.
No user service is intended by the operator. Refer all
servicing to a qualied service person to perform in a safe
and ecient manner.
Trouble Shooting
t Check wall or oor receptacle with a known
working appliance.
t Check power cord to make sure chair is plugged in
at both ends of the power supply cord.
t Check foot control plug to make sure it is properly
aligned and secured to the female plug body.
t Check “Electrical Lock-Out” it should be in the “ON”
position
t Check fuses, replace if necessary.*
Fuse Replacement*
There are two Slo-Blow glass fuses on the inlet of
the chair from the power cord. Those fuses can be
accessed for inspection or replacement by unplugging
the power cord from the chair. At the bottom of
the chair power cord receptacle there is a twin fuse
compartment. With gentle thumb pressure down

Installation and Operation Manual |MTI 526, 527P/S, & 527W 13
and backward, pull the fuse tray out of the bottom
of the receptacle to expose the two fuses. See the
Specications section for the exact replacement fuse
parameters (Figure 21).
Figure 21
527W OWNERSHIP
Purpose of Section
The 527W model chair was designed by MTI to provide
a safe and comfortable examination/treatment
platform for your Bariatric patients. All the features,
operations, cleaning, and maintenance are the same as
the 527S/P, however, the installation of the chair can be
dierent.
Installation
Because the 527W is built to see bariatric patients, it
is wider than the 527S/P. Being so wide, the 527W is
shipped without the arms attached. In order to attach
the arms and complete the installation, complete the
following instructions.
1. Take inventory on the following items:
t A left and a right arm weldment
t (2) Black sliding arm assemblies
t (4) 3/8” shoulder bolts
t (8) 3/8” lock washers
t (7) 6 x 5/8” zinc plated self tapping screws.
The arms, bolts and washer should be shrink wrapped
to the chair and the silver screws are found in the foot
section debris tray (Figure 22, 23).
Figure 22
Figure 23
2. To install the arms, rst you need to remove the
back section plastic cover. The chair is not shipped
with the (7) screws on the back for easy access to
install the arms. With both hands, pull one side of
the plastic cover until the three screw tabs clear
the metal back and then pull backward. Once
cleared, pull the other side o the same way
