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.
