Special Installation Procedures
Customer Unit
The deceleration trigger must be installed in the horizontal orientation shown in drawing #0520033A in
order to function properly. If it is not installed in the correct orientation, the carrier may land hard at the
customer unit.
Teller Unit
Hanging
The teller unit must be supported by all thread rods secured to structure above. The quick-mount wall
bracket is only to be used for temporary support of the teller unit during installation, and as a stabilizer in
a permanent installation. Do not support the teller unit by the wall bracket alone for more than 4 hours.
Guard against dropping debris into teller unit while cutting holes and during installation. The teller unit
door assembly must be kept clean from debris for proper operation. It is recommended that the top of the
teller unit be covered with paper or plastic while construction takes place. Vacuum the bottom of the door
track after installation is complete.
Timer adjustment
Adjust timer T1 for approximately 5 seconds greater than the time required for an empty carrier to be
recalled from the customer unit to the teller unit (this should be 2-3 seconds after the carrier lands at the
teller unit).
See drawing number 500354 (page 38) for additional controller settings.
Blower Unit
The blower unit must be installed in a horizontal orientation as indicated by the stickers on the housing.
If blower is installed in a closed canopy, the exhaust port must be vented to outside air to prevent
overheating.
Tubing
All tubing must be sealed properly. Seal all joints – especially those at the teller and customer units.
All inside edges of tube joints must be de-burred and ground to an angle to prevent excessive wear on
carriers.
