Installation and Set-Up
If an in-house water supply of the required purity range (50K to 1M
Ohm) is not available, an alternate water supply method can be used. A
large vented carboy (5 gal. minimum) of water in the required purity range
can be placed on top of the unit. Connect it to the 1/8” FPT water inlet
fitting, located on the rear top center of the incubator.
Note
The maximum water consumption of this incubator could be as high
as 2 gallons per day. When using an alternate water supply method, it is
recommended that the supply be checked periodically based on source
volume.

The cabinet’s 3/8” MPT drain line connection is located
on the rear (lower left side) of the cabinet. A P-trap
(Figure 1-2) is included with the unit and must be
installed on the connection.
To install the drain connection:
1. Using Teflon pipe thread tape, tape the threads on the cabinet drain
connection.
2. Using an open end adjustable wrench, install the P-trap onto the
connection. Make sure the trap section is positioned down.
3. 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. A
condensate evaporator (P/N 1900031) or condensate pump (P/N
184062) may also be used.
The environmental chamber is equipped with 4-20mA output for the
remote transmission of temperature, humidity and CO

data. A terminal
strip is located on the back of the incubator for convenience. Refer to
Figure 1-3 for terminal pin identification.
