Manual No. 08850
5.3.25
Remove the lower belt bracket screw, which was
temporarily installed. Not required for first stage only
service.
5.3.26
Apply silicon sealant to the screw and attach the
belt bracket with the lower screw only; leave the top screw
out at this time. Not required for first stage only service.
5.3.27
Place a new o-ring on the outlet connector, and
install the spring and connector onto housing assembly.
Align the screw holes and secure with the two retaining
screws.
5.2.28
Apply additional silicone sealant around the
threads on the inlet elbow and housing. Allow sealant to
cure before testing.
5.3.29
Bench test before returning to service.
5.3.30
Attach heat shield, belt, and connect respirator
hose.
6.0 TROUBLESHOOTING
6.1
Inadequate Air Flow
6.1.1
Check filter screen for debris.
6.1.2
Make sure supply air pressure is between 90 to
100 psi. A pressure regulator and gauge must be installed
at the point of attachment (where the respirator hose is
connected to the respirable air source).
6.2
Poor Heating or Cooling Performance
6.2.1
Inadequate air flow affects cooling performance.
Refer to Paragraph 6.1.
6.2.2
The temperature of the compressed air has an
effect on the climate control tube’s discharge temperature.
Make sure that none of the lines that supply compressed
air to the climate control tube is routed near any source of
heat, such as a steam radiator, furnace, etc. When
possible avoid exposure to direct sunlight.
6.2.3
Erosion of internal parts: Compressed air moving
through the control tube will eventually wear critical
components. Dirty air accelerates wear of internal parts.
6.2.4
Vortex breaker may be loose, worn, or damaged.
Inspect the breaker per Sections 5.2 & 5.3.
6.3
Ice Forming on Air Tube
6.3.1
Water in the air line will freeze when temperature
reaches 32 degrees. To avoid icing do one of the
following:
•
Lower the dew point of the compressed air below that
of the exhaust air.
•
Periodically move the temperature control lever
toward the cooler position to defrost the tube
•
Lower the outlet temperature enough to keep exhaust
air from freezing.
