Installation and Start-Up
The Series 8000DH incubator has four basic modes for incubator setup:
Run, Setpoints, Calibration and Configuration.
• Run is the default mode for normal 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.

Installing the
Incubator
SCROLL FOR PARAMETERS Arrows: Steps the operator through
parameters of SET, CAL and CON modes. The right arrow goes to the
next parameter, the left arrow returns to the previous parameter.
Up/Down Arrows: Increases/decreases or toggles the parameter value
selected in SET, CAL, and CON modes.
ENTER: Must press this key to save-to-memory all changed values.
Key: Press to mute audible alarm. See Section 4 for alarm ringback
times.
Message Display: Shows system status (Mode) at all times. Shows ‘CLASS
100’ or ‘SYSTEM OK’ during normal operation, or alarm messages if
the system detects an alarm condition (see Section 4, Alarms). The mes-
sage ‘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 particulates of
0.5 micron size or larger per cubic foot of air. Further information on
the Class 100 classification of air quality is available from Thermo.
Upper and Lower Displays: The 7 segment upper display shows temp and
RH. The lower display shows CO2and O2.
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
weight of 260 lbs (118kg).
2. Locate the unit away from doors and windows and heating and air
conditioning ducts.
3. Lift the unit 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 source before beginning any service work. ▲
Two stacking brackets (shown at left) are included in the
parts bag shipped with each incubator.
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. 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.

1. Remove vinyl from shelf channels, duct sheets, and air duct, if present.
2. Using a suitable laboratory disinfectant, clean all interior surfaces.
Caution Before using any cleaning or decontamination method except
those recommended by the manufacturer, users should check with the
manufacturer 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. ▲
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 rotate 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. Referring to Figure 1-10, note that there is no difference in the left and
right 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.

1. Locate the opening in the top left corner of the interior chamber.
Remove the tape from 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 1/4-turn fasteners. 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 the Figure 1-13.

Caution Be careful when 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. ▲
1. Remove the filter from the shipping box.
2. Remove the plastic coating from the filter, using caution not to touch
the filter media.
3. Install the filter as shown in Figure 1-13. Refer to Section 5 for HEPA
filter maintenance.
Caution The media of the filter can be damaged if mishandled.
To avoid damage to the incubator, do not operate the unit without the
HEPA filter in place. ▲
Check the unit for being level by placing a bubble-style level on one of the
shelves. Turn 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 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
unit so that it can be easily disconnected. ▲
