Stand Unit with Track in Hoistway and attach to wall
Stand the assembly up and into place inside the hoistway
(consult the application drawing for
proper placement).
Note: In some applications it may be necessary to remove the car from the trolley.
Bracket attaches to track with 3/8-16 x 3/8" hex head screw and a square nut
(inside slot of track)
Bracket Locations:
-6" from each end of track
-12" from each side of track splice
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.
Square Nut
Attach to wall with #14 x 2" wood screws
Steel Drive Cable
Travel Cable
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
Remove Shipping Wire Ties holding the Steel Drive Cable and Travel Cable together
Important
Uncoil the Steel Drive Cable and Travel
Cable, ensuring they are not twisted.
Install Other Track Pieces and Brackets
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.

Splice Bar
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

Install Other Track Pieces and Brackets
continued
For 3-Stop Dumbwaiters only:
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
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
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
The Travel Cable runs down this side of the Track
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.
Secure Steel Cable with a clevis pin and cotter pin
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
1.
Connect to power.
2.
Plug-in Call-Send cables.
3.
Plug-in Interlock cables
Call-Send Cables
-Connectors are the same.
-Cables are supplied in different lengths. The shortest cable goes to the upper floor, etc.
115 VAC 15 amp
Power Connection
Interlock Cables
-see notes below
Plug into mating connectors
Wires from Travel Cable
Header
Route wires though the knockouts in the header
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 orientation of the connectors at the header.
Upper Interlock
Middle Interlock
(3-Stops only)
Lower Interlock
Wind the Steel Cable onto the Cable Drum
Run lift in the up direction (using temporary pendant control) to wind the steel cable onto the drum
Temporary Pendant Control
Warning!
All Safety Devices (except for the final limit) are bypassed when using the pendant control.
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.
Limit Cam
Mount Cams on Track
Cam attaches to a threaded ‘nut bar’ inside the slot of the Track (nut
bar is held in place by
pieces of foam)

Notes:
• Bottom of the floor limit cams are located approximately 15” below the landing stop.
• Cams can be moved up or down to adjust the stopping position of the car.
• Switches are located on the car.
Install G.A.L. Interlocks
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.
Wires route through hole in top
Interlock mounts to
Door Jamb in 2 places
Emergency Release
(drill hole through door
face for access)
Rod goes through
Door Jamb
(may be trimmed if
necessary)
View of Backside of Interlock
Actuator Arm/Roller
(makes contact with angled cam on car)
Cut-out hoistway wall as necessary to accommodate Actuator Arm The Interlock will be located in the upper corner of the doorway, opposite of the door hinges
Face of Interlock to be located between 1/2" and 5/8" off of the inside of the ‘closed’ hoistway door
(continued on next page)
Install G.A.L. Interlocks
continued
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
Notes:
• If doors are not installed at the time of the dumbwaiter installation, the door closed switch can be bypassed by twisting wires #1 and #2 together. This safety circuit should only be bypassed during installation and troubleshooting.
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
1.
Adjust final limit switch position.
2.
Install cover on header.
