INTRODUCTION
Thank you for choosing a water jacket incubator. These units are not intended for use at
hazardous or household locations.
Before you use the unit, read this entire manual carefully to understand how to install, operate,
and maintain the unit in a safe manner. Your satisfaction with the unit will be maximized as you
read about its safety and operational features.
Keep this manual on-hand so it can be used by all operators of the unit. Be sure all operators of
the unit are given appropriate training before you put the unit in service.
Note: Use the unit only in the way described in this manual. Failure to follow the guidelines
and instructions in this manual may be dangerous and illegal.
General Safety Considerations
Your incubator and its recommended accessories have been designed and tested to meet strict safety
requirements.
For continued safe operation of your incubator, always follow basic safety precautions including:
Read this entire manual before using the incubator.
Be sure you follow any city, county, or other ordinances in your area regarding the use of this unit.
Use only approved accessories. Do not modify system components. Any alterations or modifications
to your incubator may be dangerous and will void your warranty.
Always plug the unit’s power cord into a grounded electrical outlet that conforms to national and local
electrical codes. If the unit is not grounded, parts such as knobs and controls may conduct electricity
and cause serious injury.
Do not connect the unit to a power source of any other voltage or frequency beyond the range stated
on the power rating on the data plate inside the door of the unit.
Do not modify the power cord provided with the unit. If the plug does not fit an outlet, have a proper
outlet installed by a qualified electrician.
Avoid damaging the power cord. Do not bend it excessively, step on it, place heavy objects on it. A
damaged cord can easily become a shock or fire hazard. Never use a power cord after it has become
damaged.
Do not position the equipment in such a manner as to make it difficult to disconnect power cord or
coupler.
Do not attempt to move the unit while in operation or before the unit has been allowed to cool.

INSTALLATION
Section
3
Local city, county, or other ordinances may govern the use of this equipment. If you have any
questions about local requirements, please contact the appropriate local agency. Installation may
be performed by the end user.
Under normal circumstances this unit is intended for use indoors, at room temperatures between
5 and 40C, at no greater than 80% Relative Humidity (at 25) and with a supply voltage that
does not vary by more than 10%. The unit’s technical and environmental specifications includes:
altitude not exceeding 2000 m operating and Pollution Degree of 2. Customer service should be
contacted for operating conditions outside of these limits.
CAUTION: Make sure that the incubator is located in its intended position and level before
filling the water jacket.
3.1 Power Source: The unit power requirements are listed on the data plate. PLUG THE UNIT INTO A
PROPERLY GROUNDED AND RATED RECEPTACLE OF THE CORRECT STYLE. A separate
circuit is recommended for this unit to prevent loss of product due to overloading or circuit failures
caused by other equipment. The power supply must be properly grounded (earthed) and correctly
sized to match the unit nameplate rating. The supply voltage must match the nameplate voltage
within +/- 10%. The US market units are designed for 110 volts @ 60 Hz, 5 Amps. The EU market
units are designed for 220 volts @ 50 Hz, 3.5 Amps. If supplied with a detachable cord set, plug the
female end into the inlet on the unit and the male plug into the supply. Assure that units requiring
fuses have them installed. This fuse may be at the inlet or a part of the cord set male plug. The unit
must be located to easily allow for it to be unplugged or disconnected.
3.2 Location: When selecting a site for the unit, consider conditions which may affect performance,
3.3 Lifting/Handling: These units are heavy and care should be taken to use appropriate lifting devices
3.4 Leveling: The unit must sit level and solidly. Leveling feet are supplied and must be installed in the

such as heat from steam radiators, ovens, autoclaves, etc. Avoid direct sun, fast-moving air
currents, heating/cooling ducts, and high-traffic areas. To ensure air circulation around the unit,
allow a minimum of 10cm between the incubator and walls or partitions which might obstruct free
airflow.
that are sufficiently rated for these loads. Units should only be lifted from their bottom surfaces.
Doors, handles and knobs are not adequate for lifting or transport. All moving parts, such as shelves
and trays should be removed and doors need to be positively locked in the closed position during
transfer to prevent shifting and damage.
four holes in the bottom corners of the unit. With the feet installed and the unit standing upright,
each foot can be raised by turning it in a counterclockwise direction. Adjust the foot at each corner
until the unit stands level and solid without rocking. If the unit must be moved, drain all the water
from the jacket and turn the leveling feet all the way clockwise to prevent damage.
conditions and appropriate protocol will determine the correct procedure for decontamination. A
typical decontamination procedure that is adequate for many situations has been described below.
As well, certain steps are listed that will help reduce the likelihood of contamination and the
necessity of decontamination. Whatever process is appropriate, it needs to be done on a
regularly scheduled basis. Depending on usage and protocol, this may be monthly, quarterly or
otherwise. Regardless of the decontamination procedure used, certain precautions will need to
be taken:
A. Always disconnect the unit from the electrical service when cleaning.
Assure all volatile or flammable cleaners are evaporated and dry before reconnecting the
unit to the power supply.
B. Special care should be taken when cleaning around sensing heads to prevent damage.
C. If you use chlorine-based bleaches or abrasive cleaners this will modify the stainless steel
interior finish. DO NOT USE hard tools such as metal wire brushes or steel wool. Use
non-abrasive cleaners and soft tools such as plastic brushes.
D. In the event hazardous material is spilled onto or into the equipment, appropriate
decontamination must be carried out. If there is any doubt about the compatibility of
decontamination or cleaning agents with parts of the equipment or with material
contained, please contact the manufacturer or his agent. No decontamination or cleaning
agents should be used which could cause a hazard as a result of a reaction with parts of
the equipment or with the material contained in it.
TYPICAL DECONTAMINATION PROCEDURE
1. Remove the humidity pan every week and autoclave, or wash with soap and water then
disinfect with 70% alcohol solution. Replace in the incubator with fresh water.
2. Flush the sample port tubing with 70% alcohol solution. Replace any lines that have a
green color.
3. Remove the door gaskets, clean and disinfect. Clean and disinfect all mounting grooves
for the door gaskets.
4. Remove all shelves, shelf supports, shelf standards and shields. Autoclave, or wash and
disinfect as described in item 1.
5. Wash and disinfect all interior surfaces.
6. Give special attention to cleaning and disinfecting all access ports, air bleeds, shaft holes,
electrical pass-through and any other passages into the chamber.
7. Replace all air and CO2 filters every six months or when noticeably dirty on the upstream
side. CO2 filters are located in the shadow box just behind the GAS IN fitting and in line
with the CO2 tubing kit. Units with flow meters require operator- supplied air pumps.
These pumps should be checked for proper air filtering.
OPERATION FOR MINIMIZING CONTAMINATION
1. Keep the outside of the incubator, including the air in the laboratory, as clean as possible.
This is particularly important for units placed directly on the floor. Do not place
incubators near doors, air vents or other areas of high air movement or traffic.
2. The floor around the unit needs to be clean. Units that are placed on the floor should be
mounted higher – typically on a caster platform – for ease of moving the unit during
cleaning and access to the back of the unit.
3. Minimize the number of times access is made to the chamber during normal operation.
4. Do not depend on the use of antibiotics to maintain uncontaminated conditions, as this is
an inadequate technique for sterilization. Preferably use aseptic techniques as described
above for maintaining sterile conditions in the incubator.
