3.2 Cooling (See Figures 3 through 6.)
Cooling
is
accomplished by forced air at ambient room temperature, via a packaged blower located at the bottom
of
the
cabine:t (Figure 3). Distribution
of
air
is
accomplished by an internal plenum which
is
located along the right side
of
the
cabinet opening (as viewed from the front). The air outlet from the blower enters directly into the bottom section
of
the
plenum (Figure 4). The plenum contains seven removable covers located vertically in the appropriate spaces
as
illustrated
by Figure 4.
The blower must be plugged into the
AC
panel at the rear
of
the cabinet, and the main circuit breaker on the
AC
panel
must be in the
ON
position to power up the system.
The blower air switch located on the side
of
the plenum system (Figure 4)
is
wired per Figure
7.
It
is
recommended that the blower remain on for a minimum
of
five
minutes after the Display Panel's LOCK-aN-OFF
switch
is
turned to the OFF position.
The blower
is
shut
off
by the main circuit breaker on the
AC
power panel.
A removable and washable filter
is
located behind the air int

Two types
of
covers are provided, solid and perforated (see Figures 5 and 6). Solid
.covers
are snapped in place at locations
where there are no card files. Perforated covers are used in locations having an operating card
file.
For
the
Basic Model
8/32
with no expansion, perforated covers are installed at Locations 4 and
5,
and solid covers are
installed in all other locations. If, at a later date, the first memory expansion
is
added, the solid covers at Locations 6 and 7
are replaced with perforated covers.
Two variations
of
blowers are available: 115VAC 50/60
Hz
(36-025FOI) and 220VAC 50
Hz
(36·025F02).
