2.2 Water (Humidity System) and Drain Connections
a. Connecting the Water Inlet for the Humidity System
Do not attempt to operate the humidity system without filling it with
water. The humidification heater will overheat, and the overtemp
safety thermostat will shut the humidification system down.
The humidity reservoir will require approximately one quart (0.946 liter) of
water on the initial filling. For best operation of the incubator, sterilized distilled,
demineralized or de-ionized water should be used in the humidity reservoir. Water purity
should be in the resistance range of 50K Ohm/cm to 1M Ohm/cm, or a conductivity range of
20.0 uS/cm to 1.0 uS/cm. Refer to ASTM Standard D5391-93 or D4195-88 for measuring
water purity.
Distillation systems, as well as some types of reverse osmosis water purity systems, can
produce water in the quality range specified. Tap water is not recommended as it may
contain chlorine, which can deteriorate the stainless steel. Tap water may also have a high
mineral content, which would produce a build-up of scale in the reservoir. High purity, ultra
pure or milli-q water is not recommended as it is an extremely aggressive solvent and will
deteriorate the stainless steel. High purity water has a resistance of above 1M Ohm to 18M
Ohm. Even high purity water can contain bacteria and organic contaminants. Water should
always be sterilized or treated with a decontaminant, safe for use with stainless steel as well
as safe for the product, prior to being introduced into the humidity reservoir.
The water inlet is the 1/8" FPT connection located on the rear top left corner of the
incubator. Water inlet pressure must not exceed 40 PSI. A manual shut-off valve should
be installed between the main water supply and the incubator.
To prevent mineral buildup on heater coils and humidity generator
walls, it may be necessary to clean the humidity generator and immersion
heaters with a non-metallic abrasive pad and flush thoroughly every two to
three months. Refer to Section 5.7, Cleaning and Adjusting the Humidity
Steam Generator.
Distilled or de-ionized water used in the humidity reservoir must be within a
water quality resistance range of 50K Ohm/cm to 1M Ohm/cm to protect and
prolong the life of the stainless steel. Use of water outside the specified
range will decrease the operating life of the unit and may void the warranty.

Forma® Model 3940/3949 ________________________________________Installation/Set-Up
2-3
b. Alternate Water Supply for the Humidity System
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 left corner of the
incubator.
IMPORTANT: 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 imperative that the
humidity reservoir not be allowed to run dry, as permanent damage to the steam
generator will result.
c. Connecting the Drain Line
The cabinet’s 3/8” MPT drain line connection is located on the rear (lower left side) of
the cabinet. A P-trap (Figure 2-1) 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
that the trap 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.

2.3 Remote Data Output
a. RS-232 Data Output
The Model 3940/3949 incubator is equipped with
an RS-232 Serial Communication Interface for the
remote transmission of temperature and humidity data.
A terminal strip is located on the back of the incubator
for convenience. Refer to Figure 2-2 for terminal pin
identification.
b. Remote Alarm Contacts
Remote alarm connections are also included on the terminal 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 temperature or humidity go out of the set
alarm limits.
2.4 Power Connection
The electrical junction box is located on the rear top section of the incubator. With
the junction box switch OFF, connect the incubator to an adequate power source. See
the electrical data plate mounted on the unit for electrical specifications.

2.5 Start-Up
When the humidification system is operational, the incubator may be started. Preset
the controls as follows:
Overtemp Safety Thermostat.......................... Fully Clockwise
Undertemp Safety Thermostat...... .................. Fully Counterclockwise
Main Power Switch............... .........................ON
Humidity Controller.............. .........................Desired Setpoint
Temperature Controller........... .......................Desired Setpoint
Door Heater ...................................................40% (factory set)
For best overall performance of the incubator, the refrigeration switch should be
turned on for most applications. When running Low or No humidity at high
temperatures, the refrigeration switch may be turned off.
The defrost switch must be turned on when the temperature
setpoint is 10°C, or below.
2.6 Setting the Overtemp Safety Thermostat
Allow the chamber temperature and humidity to stabilize then set the overtemp safety
thermostat as follows:
1. Turn the overtemp control knob slowly counterclockwise until the audible alarm
sounds and the overtemp indicator lights.
2. Turn the overtemp control knob clockwise approximately two units on the scale.
The alarm should be silenced and the overtemp indicator light should go out. The
overtemp safety thermostat is now set a few degrees above the control temperature
setpoint. When the chamber temperature rises to the overtemp control point, the alarm
system will activate, power to the heaters will shut off, and the chamber temperature
will be maintained at the overtemp control point.
When an overtemp condition occurs, the cause must be determined and corrected
before normal operation under the main temperature controller can be resumed.
Note: When the chamber temperature control setpoint is changed, the overtemp
safety thermostat must be reset to accommodate the change.

2.7 Setting the Undertemp Safety Thermostat
Allow the chamber temperature and humidity to stabilize, then set the undertemp
safety thermostat as follows:
1. Turn the undertemp control knob slowly clockwise until the audible alarm sounds
and the undertemp indicator lights.
2. Turn the undertemp control knob counterclockwise approximately two units on the
scale. The alarm should be silenced and the undertemp indicator light should go out.
The undertemp safety thermostat is now set a few degrees below the control
temperature setpoint. When the chamber temperature drops to the undertemp control
point, the alarm system will activate, power to the compressor will shut off, and the
chamber temperature will be maintained at the undertemp control point.
When an undertemp condition occurs, the cause must be determined and corrected
before normal operation under the main temperature controller can be resumed.
Note: When the chamber temperature control setpoint is changed, the undertemp
safety thermostat must be reset to accommodate the change.
2.8 Preparing the (Optional)
