1.4 Displays

Message Center: Displays the system sta-

tus (Mode) at all times. Displays CLASS

100 or SYSTEM OK during normal opera-

tion, or alarm messages if the system detects

an alarm condition. See Section 4.1, Alarms. The dis-

play message CLASS 100 is a timing mechanism indi-

cating 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. (For fur-

ther information on the Class 100 classification of air

quality, see Appendix A.)

Upper and Lower Displays: These 7 seg-

ment displays vary depending upon the

options present and the configuration chosen.

The upper display can display temp or RH, or

toggle between them. The bottom display

shows CO2continuously.

1.5 Installing the Incubator

a. Choosing the Location

Single and stacked units must be installed against

a wall or similar structure.

1. Maintain a three-inch clearance behind the incubator for

electrical and gas hook-ups. In addition, a three-inch

ventilation space is needed on each side of the unit.

2. Locate the unit on a firm level surface capable of sup-

porting the unit’s weight of 260 lbs.

3. Locate the unit away from doors and windows and heat-

ing 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.

c. Preliminary Cleaning and Disinfecting

1. Using a suitable laboratory disinfectant, disinfect all

interior surfaces.

d. Installing the Shelves

1. Install the large sheet metal side ducts with the tabs fac-

ing 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 1-12 shows one of the

channels installed on the right

side duct.

e. Installing the Access Port Filter and CO2

Sensor Cover Plate

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 1-13.

3. Also in the hardware bag is the CO2sensor cover plate.

Install, using the 1/4 turn fasteners. Refer to Figure 1-13

for the location.

Figure 1-13

f. Installing the HEPA Filter

Use caution 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.

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 5.6 for HEPA filter maintenance.

g. Installing the Air Sample Filter

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.

h. Leveling the Unit

Check for 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.

i. Connecting the Unit to Electrical Power

See the serial tag on the side of the unit for electrical speci-

fications or refer to the electrical schematics at the end of this

manual.

The serial tag amp rating is based on the amper-

age draw during the sterilization cycle. Normal

operating amperage is much less. Ensure that the

electrical circuit will handle the amp draw of the

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.

Plug the provided power cord into the power inlet connec-

tor on the back of the cabinet (See Figure 1-14), then into the

grounded, dedicated, electrical circuit.

j. Filling the Humidity Pan

Fill the humidity pan with sterile distilled water to within

1/2” of the top. Place the pan directly in the center of the incu-

bator floor.

For applications requiring high humidity, the pan should be

placed against the left side wall of the incubator. The side ducts

have been modified to allow the pan to be placed against the

wall. Optimum humidity is achieved by capping the CO2sam-

ple port. This will, however, cause condensation in the cham-

ber. To enhance RH recovery from door openings, place a sec-

ond humidity pan in the right side duct.

For best operation of the incubator, sterilized distilled,

demineralized or de-ionized water should be used in the humid-

ity pan. 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 con-

tain chlorine, which deteriorates 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 sol-

vent and will deteriorate 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 pan.

Check the level and change the water frequently to avoid

contamination. Do not allow the water level to fluctuate signifi-

cantly. “Dry-outs” will have an adverse effect on the humidity

level and CO2calibration of the T/C units.

Distilled or de-ionized water used in the humidity

pan 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.
