Detail 1

For best operation of the incubator, sterilized distilled, demineralized or
de-ionized water should be used in the humidity pan. Water purity should
be in the resistance range of 50K to 1M Ohm/cm, or a conductivity range
of 20.0 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 pan. High purity or ultra pure
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 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.
Caution Distilled or de-ionized water used in the humidity reservoir must
be within a water quality resistance range of 50K 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 void
warranty. s
Fill the humidity pan to within 1/2 inch of the top with sterile, distilled
water. Place the pan directly on the incubator floor to ensure optimum
humidity and temperature response.
For applications requiring higher humidity conditions, the pan should be
placed against the left side wall of the incubator. The ductwork has been
modified for this purpose. Also, the CO2 sample port may be capped to
assist in achieving greater RH. In some ambients, this may cause
condensation to form in the chamber.
Check the level and change the water frequently to avoid contamination.
Do not allow the water level to fluctuate significantly. “Dry-outs” will have
an adverse effect on the humidity level, as well as CO2 calibration.

Filling the Humidity Pan

Warning High concentrations of CO2 gas can cause asphyxiation! OSHA
Standards specify that employee exposure to carbon dioxide in any eight-
hour shift of a 40-hour work week shall not exceed the eight-hour time
weighted average of 5000 PPM (0.5% CO2). The short term exposure
limit for 15 minutes or less is 30,000 PPM (3% CO2). Carbon dioxide
monitors are recommended for confined areas where concentrations of
carbon dioxide gas can accumulate. s
The CO2 gas supply being connected should be industrial grade 99.5%
pure and should not contain siphon tubes. Install a two-stage pressure
regulator at the cylinder outlet. The high pressure gauge at the tank should
have 0-2000 psig range and the low pressure gauge, at the incubator inlet,
should have a 0-30 psig range. Input pressure to the incubator must be
maintained at 15 psig (103.4 kPa), ±5 psig.
The incubator has a serrated fitting on the back of the cabinet to connect
the gas supply. Refer to Figure 1-13. The fitting is labeled CO2 Inlet.
Make sure that the connection is secured with a clamp. Check fitting for
leaks.
Caution This incubator is designed to be operated with CO2 gas only.
Connecting a flammable or toxic gas can result in a hazardous condition.
Gases other than CO2 should not be connected to this equipment. CO2
gas cylinders have UN1013 labeled on the cylinder and are equipped with
a CGA 320 outlet valve. Check the gas cylinder for the proper
identification labels. The CO2 gas supply being connected to the incubator
should be industrial grade, 99.5% pure. Do not use CO2 gas cylinders
equipped with siphon tubes. A siphon tube is used to extract liquid CO2
from the cylinder, which can damage the pressure regulator. Consult with
your gas supplier to ensure that the CO2 cylinder does not contain a
siphon tube. Gas cylinders should also be secured to a wall or other
stationary object to prevent them from tipping. A two-stage CO2 pressure
regulator is required to be installed on the outlet valve of the gas cylinder.
Input pressure to the incubator must be maintained at 15 psig (103.4 kPa),
±5 psig, for proper performance of the CO2 control system. (A single
stage CO2 pressure regulator will not maintain 15 psig. If higher purity
CO2 is desires inside the incubator (greater than 99.5% pure), the pressure
regulator should be constructed with a stainless steel diaphragm along with
specifying the purity of the CO2 from the gas supplier. Follow the
manufacturer’s instructions to ensure proper and safe installation of the
pressure regulator on the gas cylinder. Consult your facility safety officer to
ensure that the equipment is installed in accordance with the codes and
regulations that are applicable in your area. s

Connecting the Gas
Supply

Now that the incubator has been properly installed, connected to power,
filled with water, humidity pan filled, and connected to gas supply, system
setpoints can be entered. The following setpoints can be entered:
temperature, over temperature, and CO2.
The temperature setpoint range (settable to within 0.1°C) is 10° to 55°C
for units with a T/C sensor, and 10° to 50°C for units with an IR sensor.
The lowest temperature the incubator can control is +5°C above the
ambient temperature at the incubator’s location.
This incubator is shipped from the factory with a temperature setpoint of
10°C. At this setting, all heaters are turned off.
To change the temperature setpoint:
1. Press the Mode key until the Set Temp indicator lights.
2. Press the up/down arrow until the desired temperature setpoint is
displayed.
3. Press Enter to save the setpoint.
4. Press the Mode key until the Run Indicator lights to go to Run mode.
Caution The overtemp circuit is designed as a safety to protect the
incubator only. It is not intended to protect or limit the maximum
temperature of the cell cultures or customer’s equipment inside the
incubator if an overtemp condition occurs. s
The factory setting for the Overtemperature setpoint is 40°C. It can be set
over a range of temp setpoint +0.5°C to 60°C. If the temperature setpoint
is moved above the Overtemp setpoint, the Overtemp will automatically
update to 1.0°C + the temp setpoint. It is recommended that the
Overtemp setpoint be 1°C over the temp setpoint.
