MIL-HDBK-1130
carbon dioxide meters and similar instruments should be refilled. Stored
glass containers should be installed. Thermostats should be checked. Check
valves, pressure regulators, etc. , should be inspected to make sure they are
operable. When boilers are fired, combustion safeguards should be inspected
and tested to ensure proper sequence and operation of the programming
controls.
Heating Equipment and Piping. All equipment and piping should
2.2.8.5
first be checked for leaks or corrosion and repaired if necessary. All clean-
out and drain plugs should be placed back, and any screens removed. Lines to
boilers should be uncapped. Allow water to circulate through the system to
flush out any debris. Check all controls before firing the system up.
Space Heaters and Warm-Air Furnaces. Firing equipment, smokepipes,
2.2.8.6
and any other pieces removed during inactivation should be cleaned and
reinstalled. Waterlines to humidifiers should be re-opened, and all
ventilation openings should be uncovered. The draft control in the stack
should be checked for proper operation. The unit should then be fired and
tested.
Refrigeration Equipment Inactivation
2.2.9
Iceplant and Brine Systems. The refrigerant should be removed from
2.2.9.1
the equipment and stored in cylinders appropriately marked with the type of
refrigerant, date and equipment. Brine tanks, water tanks, piping systems,
strainers, and traps should be thoroughly flushed with fresh water and
drained. Blowers, agitators, crane equipment, can fillers, ice-dump
equipment, exposed surfaces of brine coolers and cooling coils, and all
unprotected metal surfaces should be protected with paint. Ice cans should be
cleaned, repainted as required, and stored in a dry place.
2.2.9.2
Refrigerated Spaces. Interior surfaces of cold storage rooms and
refrigerators should be cleaned. Movable shelving, floor gratings, and
dunnage should be removed, cleaned, and dried; meat hooks should be removed,
cleaned, and packed in suitable cartons. These parts should be stored in cold
storage rooms or refrigerators. Meat tracks, scales, door hinges, and
miscellaneous hardware should be cleaned and coated with a light film of
preservative. Door gaskets should be cleaned with doors fastened in a
partially open or open position. To ease the weight on the hinges, blocks
should be placed under doors. Exterior openings should be covered to exclude
the weather.
Refrigeration Equipment Reactivation
2.2.10
Refrigeration Equipment. The refrigeration equipment should first
2.2.10.1
be checked for leaks and repaired. The system can then be refilled with the
stored refrigerant or with new refrigerant when necessary. Check the oil in
the crankcases of compressors. If it is dirty or contaminated, the crankcases
