Blower
All blower packs are suitable for installation in restricted access locations at maximum operating ambient
40C deg/104F deg.
Note
: 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.
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 Appendix A for switch settings and other timing settings.
Maintenance
Carriers
Carriers should be inspected regularly for signs of wear. Carriers landing hard at either customer or
teller unit may be a sign of worn wear bands on carrier.
Carriers should be replaced regularly – usually every 3-6 months, depending on usage.
Customer Unit & Teller
The carrier deceleration switches are required for proper operation. If they are inoperable, the carrier
will land hard at the customer unit.
