SECTION X - SHUT DOWN
A. Shut off system air fan.
B. Close system outside air shutters or otherwise
prevent air leakage into system. Open strainer
blowdown valve and close valve after the trap.
C. Shut off steam or water supply after circulation fan
has stopped and air in the inlet ductwork is above 35
degrees.
D. As soon as possible, open drip leg in return main
(on steam units), or drain and air valves (on hot water
units), and allow water to drain.
E. Do not expose a coil which has been shut
down to sub-freezing air flow as water droplets in
tubes may freeze, resulting in coil freeze-up when
coil is restarted. (See starting instructions.)
SECTION XI - MAINTENANCE
A. The Wing heating coil should be periodically
inspected for continuous satisfactory operation. Loose
nuts, bolts, screws and damper linkage should be
tightened. Crank arm pivots, control linkage, and
damper rods should be checked for wear and replaced
if worn.
B. Steam traps should be checked for proper
operation. Strainers, dirt pockets and drip legs should
be cleaned periodically.
