MANUAL ADDENDUM
Re: Incubator CO2Control
CAUTION!
If the incubator sustains a power failure long enough to affect temperature and in turn affect
humidity, then the CO2readout will be incorrect. The unit will return to NORMAL,
indicating correct chamber conditions.
NOTE: PLEASE ALLOW ADEQUATE TIME FOR THE UNIT TO STABILIZE. (Short
OFF and ON power failures will not adversely affect the chamber operation.)

SECTION 1 - INTRODUCTION
1.1 THE WATER JACKET: KEY FEATURES
Forma’s water jacket design represents the best combination of economy,
accuracy and reliability available in today’s technology. Some of the salient
features include:
• A door heater which adjusts automatically to ambient conditions,
providing a condensate-free inner door for unhampered viewing of the
product in the chamber without unnecessary door openings, which
temporarily disturb temperature, humidity, and CO2control.
• Ultra-flat, vibration-free shelves to provide optimal culturing conditions.
• Direct-set CO2, temperature, and alarm setpoints.
• Tamper-proof controls to prevent unauthorized or accidental adjustments.
• Digital readout of temperature and CO2levels in the chamber surrounding
the product.
• A sealed chamber to minimize CO2consumption.
• A sealed water jacket to minimize water evaporation.
The water jacket incubator is designed for ease of serviceability by providing:
• Front access to all components so that the unit need not be moved for
service, repair, or routine maintenance.
• A slide-out control panel for easy access to electrical components.
• Plug-in CO2, and temperature/alarm modules to facilitate servicing or
replacement of a particular control module.
• Self-diagnostic switches in the control modules to aid in troubleshooting
the system and localizing problems.
Forma Scientific, Inc. ____________________________________________________
The design of the water jacket also allows for ease in disinfecting or autoclaving
with a minimum of unit downtime.
• There are no cracks or crevices in, or around, the chamber walls to harbor
hidden or hard-to-reach bacterial growth.
• Stainless steel shelves, shelf channels and duct sheets are easily removable
without tools for cleaning and disinfecting the entire interior.
• A blower wheel that is disposable and easily replaced.
Careful consideration has been given to the importance of product protection
through the addition of:
• An Add Water audible alarm and pilot light to alert the operator when the
water level in the water jacket has become too low for efficient operation.
• Audible and visual CO2alarms which are activated when the CO2
percentage in the chamber deviates 1% above or below the CO2control
setpoint.
• An overtemperature alarm that is activated when the chamber temperature
rises above the control setpoint.
1.2 AUXILIARY EQUIPMENT

intermediate level. Second stage reduces pressure to recommended incubator
inlet pressure. Permits stable CO2flow on high or low demand through the
entire cylinder supply. Catalog # 965010
10. CO2Gas Guard
For use with automatic CO2incubators only. Protects dual tank CO2supply by
automatically switching to another tank when one supply is exhausted. Audible
