Installation and Start-Up
The Model 370 Series incubator has four basic modes which allow
incubator setup: Run, Setpoints, Calibration and System Configuration.
• Run is the default mode in which the incubator will normally be
during operation.
• Set is used to enter system setpoints for incubator operation.
• Calibration is used to calibrate various system parameters.
• Configuration allows for custom setup of various options.

Scroll for Parameters Arrows: Steps the operator through parameters of
SET, CAL and CONFIG Modes. The right arrow goes to the next
parameter, the left arrow returns to the previous parameter.
Up Arrow: Increases or toggles the parameter value selected in SET, CAL,
and CONFIG Modes.
Enter: Must press Enter key to save to memory all changed values.
Down Arrow: Decreases or toggles parameter values selected in SET, CAL
and CONFIG Modes.
Silence Key: Press to mute audible alarm. See Section 4 for alarm ringback
times.
Message Center: Displays system status (Mode) at all times. Displays
CLASS 100 or SYSTEM OK during normal operation, or alarm mes-
sages if the system detects an alarm condition (see Section 4, Alarms).
The display message CLASS 100 is a timing mechanism indicating that,
under normal operating conditions with the HEPA filter installed, the air
inside the chamber meets the Class 100 air cleanliness standard for par-
ticulates of 0.5 micron size or larger per cubic foot of air. Further infor-
mation on the Class 100 classification of air quality is available from
Thermo.
Upper and Lower Displays: These 7 segment displays vary, depending on
options present and configuration chosen. The upper display can display
temp or RH, or toggle between them. The bottom display shows CO2
continuously.
1. Maintain a minimum three-inch clearance behind the incubator for
electrical and gas hook-ups. In addition, a three-inch ventilation space
is needed on each side.
2. Locate the unit on a firm level surface capable of supporting the unit’s
weight of 260 lbs. (118kg).
3. Locate the unit away from doors and windows and heating and air
conditioning ducts.
4. Lift the unit only by the sides of the cabinet base. Do not attempt to
lift it by the front and back. This places stress on the outer door
hinges.

Warning Install stacked units against a wall or similar structure. ▲
Warning With incubators in a stacked configuration, do not leave both
exterior doors open at the same time. ▲
Warning If the units have been in operation, turn them both off and
disconnect the power before beginning any service work. ▲
Two stacking brackets (shown at left) are included in the
parts bag shipped with each incubator.
Figure 1-3. Stacking Brackets
1. Remove the cover plate securing the door cord from the incubator to
be on top. See Figure 1-4. Disconnect the plug from the connector.
2. Remove the four screws securing the door hinges to the unit. Remove
the door and set it aside.
3. Unscrew the two hole plugs from the top
cover of the incubator to be the bottom of
the stack (Figure 1-5).
4. Unscrew and remove the 4 leveling feet from
the unit to be stacked on top and lift it onto
the bottom unit. Align all sides.
Warning This incubator weighs 260 lbs.
(118kg). Have sufficient personnel available
when lifting. Lift the unit by the sides of the
cabinet base to avoid placing stress on the outer
door hinge. ▲

5. Insert the stacking brackets into the slots
at the back of the stacked units as shown
in Figure 1-7.
6. Align the slotted holes in the brackets
with the mounting holes on the back of
the top incubator. Secure the brackets
with the screws and washers provided in
the parts bag. See Figure 1-8.
7. Thread one 1/4 x 20 bolt and washer
included with the stacking brackets,
into the hole behind the cover plate.
Do not tighten. Refer to Figure 1-9.
8. Remove the cover plate from the same
area on the other side of the top unit.
9. Thread the other 1/4 x 20 bolt and
washer into this hole.
10. Tighten the bolts on both sides.
11. Assemble the door hinges to the unit.
Secure with the screws.
12. Plug the door cord into the connector,
as previously. Secure the cover plate.
13. Install the cover plate on the other side of the unit.
14. The stacked incubators are ready for service.

Installing the Shelves
1. Remove vinyl from shelf channels, duct sheets, and air duct, if present.
2. Using a suitable laboratory disinfectant, clean all interior surfaces.
1. Install the large sheet metal side ducts with the tabs facing into the
center of the chamber with their slots up. There are no right side or
left side ducts, simply turn one of them to fit the opposite side. Tilt
the side ducts as they are placed into the chamber so the tops fit into
the top air duct, then guide them into the vertical position. Figure 1-
10 shows the side duct as it would be oriented for the right side of the
chamber.
2. Note that there is no difference in the left and right side shelf channels.
3. Install the shelf channels by placing the channel’s rear slot over the
appropriate rear tab on the side duct. Pull the shelf channel forward
and engage the channel’s front slot into the side duct’s appropriate
forward tab. Refer to Figure 1-11.
4. Figure 1-10 shows one of the channels installed on the right side duct.

Installing the Air
Sample Filter
1. Locate the opening in the top left corner on the inside of the chamber.
Remove the tape covering the opening on the outside of the unit.
2. Locate the stopper with filter in the hardware bag. Lift the metal port
cover and install the assembly in the opening inside the chamber. See
Figure 1-12.
3. Also in the hardware bag is the CO2sensor cover plate. Install, using
the thumbscrews. Refer to Figure 1-12 for the location.
1. Remove the filter from the shipping bag.
2. Install the air sample filter assembly to the black hose barb behind the
top duct.
3. Insert the other end of the filter assembly onto the metal tubing on the
top duct. Refer to Figure 1-13.
Caution Be careful when handling the filter. The media can be damaged if
it is mishandled. To avoid damage to the incubator, do not operate the unit
without the HEPA filter in place. ▲

the hex nut on the leveler counterclockwise to lengthen the leg or
clockwise to shorten it. Level the unit front-to-back and left-to-right.
See the serial tag on the side of the unit for electrical specifications or refer
to the electrical schematics at the end of this manual.
Caution Serial tag amp rating is based on amperage draw during
sterilization cycle. Normal operating amperage is much less. Ensure that
electrical circuit will handle amp draw of sterilization cycle.
Connect the incubator to a grounded, dedicated circuit. The power cord
connector is the mains disconnect device for the incubator. Position the
incubator so the unit can be easily disconnected. ▲
