SECTION IV. OPERATION UNDER UNUSUAL CONDITIONS
2.9 OPERATION UNDER EXTREME ENVIRONMENTAL CONDITIONS.
2.9.1 Operation in Extreme Heat. Operation under conditions of high heat may cause equipment problems due to
thermal expansion. Unisex coupling seals are especially subject to damage. Basic system operation is as described in
TM 10-4930-250-13&P. The following additional steps and recommendations should be implemented to protect the
system from direct sunlight to the extent possible.
a.
Position system components in the shade of trees, buildings, etc. If shade is available only part of the day,
choose afternoon shade.
b.
Shade components with tarpaulins or other fabric. Keep fabric wet if possible. Do not block air circulation.
c.
Shade components with leafy branches. Do not block air circulation.
d.
Use any material available to create shade without blocking air circulation.
2.9.2 Operation in Extreme Cold. Operation under conditions of extreme cold may cause equipment problems due to
loss of flexibility. Unisex coupling face seals are especially subject to damage. Basic system operation is as described in
TM 10-4930-250-13&P. The following additional steps and recommendations should be implemented to protect the
system to the extent possible.
a.
Set up system in area protected from wind, if possible.
b.
Handle all components with care to avoid cracking or fracture.
c.
Remove snow or ice from coupling ends before making connections to prevent entry of foreign material into
system.
d.
Make and break connections slowly and carefully to avoid cracking or splitting of face seals.
e.
Drain water from sump to avoid freezing.
2.9.3 Operation in Strong Winds.
a.
Shield couplings during connection or disconnection to prevent entry of foreign material into system.
b.
Keep dust caps in place on all disconnected couplings.
2.9.4 Operation Under Sandy or Dusty Conditions.
a.
Shield couplings during connection or disconnection to prevent entry of foreign material into system.
b.
Keep dust caps in place on all disconnected couplings.
2.9.5 Operation in Rain. Shield couplings during connection or disconnection to prevent entry of water into system.
