All debris and extraneous or surplus material is removed
from the inside of the Station, as well as from the area
immediately surrounding the Station, and "deep-sixed".
2.
After the Station is '"broom-clean" and before the mothballing
process begins, a "Check List of Items in Scientific Stations
(Mothballed)'"'", Form 1 F-22, is completed by the Engineering
Division's representative, who tags each item as it is listed.

All installed equipment is to remain in the Station, with the
exception of equipment which is damaged beyond repair;
equipment which is to be removed for repair and subsequently

Preservation of specific equipment is accomplished in the
following manner:
(a)
Air Conditioning Systems:
i
Pump down the entire refrigeration system, isolating the freon in the condensers and leave be-
tween 15 to 20 pounds pressure as a holding charge
on all the refrigerant lines, cooling coils and compressors.
Li
Close the suction and liquid line shut-off valves at
each cooling coil.
ili
Close the suction and discharge service valves on
the compressors. Close line shut-off valves between compressors and installation having two
compressors piped in for parallel operation.
iv
Drain and clean salt water condensers. Check
condition of condenser heads and obtain necessary
data for replacement, if needed. Blow out and
drain salt water lines, where possible. A water
soluble oil solution is used to flush out the condensers and salt water lines to help prevent future
corrosion. Renew zinc plugs where they are used.
Vv
A corrosion preventative, or "Vaseline", is applied
to both compressor fly wheel and motor pulley
belt grooves and then wrapped for protection.
Belts are wrapped orstored in plastic bags and
tied to the compressor.
