Section 2 - Installation and Set-Up
2.1
Location
a.
Choosing the Location
Locate the unit on a firm, level surface in an area
of
mini-
mum ambient temperature fluctuation. A minimum
of
twelve
(12) inches
of
clearance is required at the top
of
the incubator
and a minimum of twelve (12) inches
of
clearance is required at
the rear
of
the incubator. This space is necessary to allow ade-
quate air flow around the refrigeration system.
b.
Preliminary Cleaning and Disinfecting
Disinfect all interior surfaces with a general-use laboratory
disinfectant. Rinse thoroughly with sterile distilled water, then
70% ethanol. Dry with a sterile cloth as needed.
Disinfect the shelf channels and shelves, then rinse with
distilled water before installing.
Before using any cleaning or decontamination
method except those recommended by the
manu-
facturer, users should check with the manufactur-
er that the proposed method will not damage the
equipment.
Am
Accidental spills
of
hazardous materials on or
• inside this unit are the responsibility
of
the user.
c.
Installing the Shelves
The shelves may be installed at any level
in
the incubator.
Install a shelfchannel on each side. With the tabs pointing up,
attach the channel by
locating the rivet into a
slotted hole, far end flrst.
Pull the channel toward
the front and slide the
front rivet on the channel
into the slotted hole and
press down. Make sure
that the channels are
opposite each other so that
the installed shelf
wiII
be

level.
d. Leveling the Unit
Place a bubble-type level on a shelf inside the incubator.
Adjust the feet as needed; counterclockwise to lengthen or
clockwise to shorten. Level the unit front-to-back and left-to-
right.
2.2 Attaching the Drain Connections
The cabinet's 3/8" MPT drain line connection
is
located on
the rear (lower left side) of the cabinet. A P-trap (Figure 2-2) is
included with the unit and must be installed
on
the connection.
To
install the drain connection, push a piece
of
3/8"
ID
tub-
ing onto the trap and direct the tubing to a convenient drain.
Install a hose clamp on the tubing,
if
desired.
2.3 Remote Data Output
a.
4-20 Milliamp Output
The environmental chamber is equipped with 4-20 rnAout-
put for the remote transmission
of
temperature data. A terminal
strip is located on the back
of
the incubator for convenience.
Refer to Figure 2-3 for terminal pin identiflcation.
b.
Remote Alarm Contacts
Remote alarm connections are also included on the termi-
nal strip (Figure 2-2) providing Normally Open (N.O.) and
Normally Closed (N.C.) contacts. C
is
the Common terminal.
The remote alarm will activate when either the incubator's tem-
perature or humidity go out
of
the set alarm limits.
