I~iE1SORANDUM FOR: All Computer Ops. Personnel
SUBJECT . Procedure in the Event of Air-Conditioning Problems
1. Until the installation of an automatic temperature alarm
system, I am asking the shift supervisors and their operators to
monitor the computer room temperatures very closely. There is a
temperature recorder located on the console in the 1110 computer
room, which is to be used as the monitoring device. This recorder
requires winding like a clock, and should he wound each morning.
The recording chart does not require changing each day, but approxi-
mately every three or four days, unless of course there has been re-
corded a'significant temperature change in which case I will require
that chart for my records.
2. The following are steps to be immediately taken in the event
of a significant temperature change. The chart usually records room
temperatures between 72/73', so i would suyyest tildt Le1lgit1'dLU1'd
readings of 75? or better are significant. Lower temperatures are not
as crucial or critical as higher temperatures, unless.they record
below 68?:
a. In the event of a significant temperature change, immedi-
ately notify myself or the Branch Chief's. We inturn will contact
the Logistics Branch, and alert Ron Wootters' section (PSS). After
normal duty hours and on weekends the shift supervisor should im-
medi.ately notify Security.
b. If we are informed that we have lost our air-conditioning,
but will be returned to us in 5 or 10 minutes, then begin shutting
down all equipment not needed. If the outage will be longer than
10 or 15 minutes then it is suggested you begin to shut down the
entire computer systems, and remain down until temperatures have
stabilized.
c. If it becomes necessary to go completely down then be sure
to notify all persons concerned,Ops. Officers-, Univac C.E.'s, etc.
d. In regards to 1782 drums and disk drives the only immediate
steps necessary are to lift heads and retract heads, leaving drums
and drives rotating.

Operating rtequii?ements:
a. Temperature - 65 degrees F t.ol BCldegrees F.
b. Humidity - 35% to 70%.
The same design points Should be selected as listed for the U4914.
If the false floor is used on air plenum the following design point
should be selected.
Temperature - 65 degrees F + 2 degrees
Humidity - 60% ? 5i
Fluctuations of the environment contribute most to unreliable operation,
however, operating with a room tcirp-nratu:re of 76 degrees F/80 degrees F
or a plenum temperature of 70 degrees F/75 degrees F would show their
effect.
iiank' you for allowing me to be of assistance in this matter.

e. On a computer shut-down it is absolutely necessary to call
the Univac C.E.'s and inform them 3f our situation. They should
be present to po,.er the computer systems back-u:.
