COMMERCIAL CONTROL DAMPER OPERATION & MAINTENANCE
Regular maintenance is essential to ensure that a building’s air control system will perform as intended under
normal conditions . Regular maintenance should include periodic testing of all equipment associated with the air
control system such as initiating devices, fans, dampers, controls, etc . Ruskin recommends each damper be cy-
cled and tested every 6 months and in accordance with local codes and actuator manufacture recommendations
(if damper has actuator) . If dampers are installed in potentially dirty airstreams, the blades and other internal parts
may need annual cleaning to avoid dirt build up .
MAINTENANCE
•
Remove any foreign material.
•
Verify that hardware used to install damper does not contact moving parts of the damper.
•
Lubricate linkage, bearings and other moveable parts with a silicone lubricant. Do not use petroleum-base
products as they could cause excessive dust collection .
•
Operate (open and close) the damper via the actuator or extended shaft.
•
Check the blade linkage to make sure the blade shafts and blades rotate 90° from full open to full closed.
•
Consult Ruskin if problems are encountered.
OPERATION
•
Operate damper through full cycle, verify that all blades open and close completely. Check for loose linkage from
actuator (if used) through jackshafting (if multi-section) and damper side linkage . Tighten linkage as required .
