Motor Stand Unit with Track in Hoistway and attach to wall
Bracket attaches to track
with 3/8-16 x 3/8" hex head
screw and a square nut
(inside slot of track)
Tip: The square nuts are held
inside the track slots with
pieces of foam, do not
remove the pieces of foam
until installation is complete.
Attach to wall with #14 x 2"
wood screws
Bracket Locations:
-6" from each end of track
-12" from each side of track splice
Note: In some applications it may be
necessary to remove the car
from the trolley.
Stand the assembly up and into
place inside the hoistway
(consult the application drawing for
proper placement).
Square Nut Remove Shipping Bracket from top of Car
The Shipping Bracket is used to
hold the car in place during
shipment. Remove and discard
the bracket
Important
Uncoil the Steel Drive Cable and Travel
Cable, ensuring they are not twisted.
Remove Shipping Wire Ties

Splice Bar
Set Screw
Each piece of Track has 3 Splice Bars
installed in the lower end. Loosen the
set screws (5/32" allen wrench) and
slide the bars half way out and re-tighten
the set screws.
Slide the Track and
Splice Bars into the
Track mounted to
the wall
Tighten all set screws
when the track joint is
properly aligned
Attach the track
to the wall with
track brackets

Sliding Cam
Insert Sliding Cam
into slot of Track
Threaded Nut Bar is
pre-installed in Track
Attach Sliding
Cam Stop to side
of Track at Nut Bar
For 3-Stop Dumbwaiters only:
The sliding cam should contact the car top switch when the car is
at the middle landing. Final adjustment can be made after the
middle landing cam is adjusted.
The sliding cam rides along with the car when the car is at or
above the middle landing stop.
The switch tells the controller which direction to run when a
middle call is registered. Set Header on top of Track and attach Steel Cable
Secure Steel Cable with a
clevis pin and cotter pin
Header sets on
top of the track
(It is not mechanically
fastened to the track)
Tapped screw holes
are for attaching the
Header Cover later in
the Installation
Insert end of Steel
Cable into Header
The Final Limit Switch
slides into the top of the track
before the header is set in place
(The ultimate location of the
switch will be determined
later in the installation)
Note: The Final Limit Switch is a safety device
that stops the operation of the dumbwaiter
if the car should overrun the upper limit. It
disables all controls.
The Travel Cable
runs down this
side of the Track
Secure Travel Cable inside
the Track (above black
plastic chain) with adhesive
clips.
(adhesive goes
against side wall of track)
Space clips approximately
24 between the plastic
chain and track header Make Wiring Connections at Header

Call-Send Cables
-Connectors are the same.
-Cables are supplied in different
lengths. The shortest cable
goes to the upper floor, etc.
Interlock Cables
-see notes below
Plug into mating
connectors
Wires from Travel Cable
Upper Interlock

(3-Stops only)
Lower Interlock
Interlock Cable Note:
The connectors for the interlocks are
different to prevent being plugged into
the wrong interlock.
The photo to the right shows the orienta-
tion of the connectors at the header. Run lift in the up direction (using
temporary pendant control) to
wind the steel cable onto the
drum
The cable should be wound onto the
grooves of the drum.
Ensure that no
grooves are skipped or that the cable
does not wind over itself.
Warning!
All Safety Devices (except for the final
limit) are bypassed when using the pen-
dant control.

The G.A.L. interlock prevents the dumbwaiter from
operating if a hoistway door is opened. The hoistway
door is unlocked mechanically when a cam on the car
contacts a lever arm on the interlock.
(continued on next page)
The Interlock will be
located in the upper
corner of the door-

door hinges

Notes:
If doors are not installed at the time of the dumbwaiter installation, the door closed switch can be by-
passed by twisting wires #1 and #2 together.
This safety circuit should only be bypassed during installa-
tion and troubleshooting.
Route the Interlock Cable thru hole
in top of Interlock and connect wires
#1 and #2 to the terminal block and
the green wire to ground
Attach the Keeper to the inside of
the hoistway door in alignment with
the Interlock
The Cam on the Car can
be adjusted vertically and
horizontally
The angle of the Actuator Arm
can be adjusted for proper
actuation of the Interlock Test in Automatic Operation
The car door(s) and hoistway doors must be closed for the
dumbwaiter to run
Test the following items to confirm proper setup of the
dumbwaiter:
Verify each call-send control calls and sends the
dumbwaiter to the appropriate landing.
Verify the floor of the dumbwaiter stops level with the
sill at each stop. Adjust position of cams if necessary.
Verify all controls are inoperable if the car door is open.
Verify all controls are inoperable if a hoistway door is
open. Test each hoistway door individually.
Verify each hoistway door locks when the dumbwaiter
car is not parked at that landing.
Verify all controls are inoperable if the final limit switch
is actuated.
Verify all controls are inoperable if the slack cable
device switch is opened.
Travel Cable: Verify that the travel cable properly
travels inside the track and adhesive clips are properly
installed.
Hardware: Verify all track mounting hardware, switch
cams and car hardware are securely tightened. Complete the Installation
