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 three (3)
inches clearance is required at the top and back of the incuba-
tor. This space is necessary to allow adequate air flow around
the refrigeration system. At least eight (8) inches of clearance is
required at the top of the incubator for service access.
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.
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 shelf channel on each side. With the tabs pointing up,
attach the channel by
locating the rivet into
a slotted hole, far end
first. 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 oppo-
site each other so that
the installed shelf will 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 con-
nection 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 tubing 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 4-20mA out-
put for the remote transmission of temperature or CO
2
data. A
terminal strip is located on the back of the incubator for con-
venience. Refer to Figure 2-3 for terminal pin identification.
b. Remote Alarm Contacts
Remote alarm connections are also included on the termi-
nal strip (Figure 2-3) 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 CO
2
go out of the set alarm limits.
