2 CHAMBER FEATURES
2.1 Configurations
The base GEN1000 chamber can be fitted with any of the following specially configured kits and
each kit is also available with an LED lighting option:
An SH kit is either a two-tier or an SH-XTIER three-tier configuration using horizontal
airflow over multiple shelves optimizing the growth area for shorter plants, like
Arabidopsis. Ideal for research in propagation, genetics, physiology, and other moderate
light experiments.
The TA kit is a single-tier configuration providing upward airflow, maximum growth height
and light intensity for taller plants such as cereal crops, horticultural plants, and
silviculture.
The TC kit is a four-tier configuration using low light to maximize space. It also provides
upward airflow minimizing condensation in petri dishes and jars used in propagation and
genetics experiments.
The IN kit is a four-tier configuration using horizontal airflow and low light levels
optimizing the incubation of plantlets and insects.
2.2 Control System
The control system provides advanced programming capabilities, allowing ramping or stepping
of environmental conditions to match research requirements. User programmable ″set and
forget″ alarms track the chamber operation relative to user-defined setpoints. Visual and audible
notifications provide a further level of protection. For remote monitoring and control, the
chamber comes ready to communicate with Conviron’s Central Management™ or CMP-Link.
Refer to the included Conviron CMP6060 Operator’s Manual for complete instructions.
2.3 Air Intake and Exhaust
The chamber includes manually adjustable fresh air intake and exhaust ports to allow for
chamber air exchanges. Exhaust air flows to ambient with no additional connection required.
2.4 Instrumentation Ports
One 2″ (50mm) access port with a light-tight cap is provided on the right side of the chamber.
The port allows small instruments and monitor leads to be inserted into the chamber without
opening the front door, and without significantly changing the environment within the chamber.
2.5 Network Connectivity
An RJ45 port is included for connection to the facility network.

900 such as scheduling and programming, table views for data, comprehensive graphing, realtime status (including alarms, sensors and IOs), retrieval and exporting of chamber data, time
synchronization and a remote interface are available for the chamber.
2.9 Central Alarm Contact
The Central Alarm Contact (CAC) (Figure 3-49) consists of a normally closed dry contact
energized by a control system alarm output that is connected to a Building Management System
(BMS) or an optional auto dialer. When an alarm condition occurs, that contact opens,
interrupting the circuit from the BMS (or other system) to indicate an alarm. The CAC is only
triggered by shut-down alarms.
The connection point to the BMS is a receptacle on the back panel of the chamber. This
receptacle is connected to a relay that operates when a chamber alarms. The wire connections
of the receptacle must be completed according to the electrical drawings. The electrical load
must be within the rating of the technical specifications. The receptacle is mated with the plug
and then screwed tightly together.

3.3 Move the Chamber Into Final Position
The chamber casters make moving the chamber into final position easy and straightforward.
The chamber could cause serious personal injury if it falls while moving into final
To move the chamber into position:
1. Ensure the locks on the front casters are in the unlocked position (Figure 3-4, Panel
A).
2. Slowly push the chamber into its final location.
3.4 Level the Chamber
The GEN1000 is equipped with four levelers (Figure 3-4, Panel B) to prevent the unit from
rolling on its casters once installed, and to compensate for any variations in the floor level.
Figure 3-4 Chamber Levelers
The levelers at the four corners at the bottom of the base must be adjusted to take the weight of
the unit off of the casters. Once the chamber is moved into position, adjust the levelers until they
are in firm contact with the floor and the chamber is level.
To adjust the levelers:
1. Use a ¾″ (18mm) open end wrench, or a medium sized adjustable wrench, to turn the
levelers under the back wall of the chamber clockwise to lower the foot into firm
contact with the floor.
2. Adjust the levelers under the front corners until the gap between the caster and the
floor is at least 1/8″ (3mm) and no more than 1/4″ (6mm).
3. Ensure the chamber is level in both the side-to-side and front-to-back directions for
proper drainage.

3.5 Configuration Kit Overview
The base GEN1000 chamber can be fitted with one of four specifically configured kits, each with
airflow, lighting, and shelving designed to suit specific plants and applications. Each kit allows
researchers to convert the chamber and adapt to a variety of research programs requiring
different light intensity, airflow direction, growth height, and growth space.
3.5.1 Airflow
Continuous airflow is critical to the efficient operation of the chamber. Fresh air may be
introduced using the fresh air port located on the side of the chamber.
Conditioned air is drawn down from the refrigeration coil and enters the interior of the chamber
thought a rigid metal plenum in the rear wall of the chamber.
The SH and IN kits both use a perforated cover plate that distributes airflow from the plenum
horizontally across multiple shelves.
The TA kit uses solid cover plates and distributes uniform upward airflow through the chamber
floor.
The TC kit incorporates individual air-shelves that distribute air vertically to minimize
condensation within petri dishes and containers. Figure 3-5 shows airflow, light intensity, and
growth height comparisons between the four configurations.

3.5.2 Adjustable Wire Shelves and Lamp Canopies
Wire shelves are supported by four metal clips attached to the four pilaster strips inside the
chamber (Figure 3-6).
Lamp canopy supports (Figure 3-7) are two long metal brackets attached between the two
pilaster strips on the same side of the chamber. The lamp canopy then simply slides onto the
brackets and is connected to control and power receptacles on the right side of the chamber
interior. Control and power cables are color coded and equipped with unique connector plugs
(Figure 3-7).
Light Canopy Control - Four small receptacles are used to control the lighting fixtures. The
yellow plugs are mated with the receptacles and then pushed firmly together.
Light Canopy Power - Four large receptacles provide power to the lighting fixtures. The black
plugs are mated with the receptacles and then screwed tightly together.

3.5.3 Unifloor® (TA Kit)
The Unifloor®, available only in the TA Kit, has openings that allow conditioned air to be
distributed evenly up through the floor into the chamber. Excess irrigation water and condensate
will drain out of the chamber to the floor drain.
Figure 3-8 Unifloor
To ensure proper airflow and water drainage, keep the vents and drain channels in
the Unifloor clear of debris.
3.6 Install the Light Canopies and Shelving Configuration Kits
Conviron chambers are configured onsite using one of four pre-packaged lighting and shelving
kits; SH for short plants, TA, for tall plants, TC for tissue culture, or IN for incubator
configuration.
Images used in the installation instruction may differ from the actual kit. However, the
installation steps and procedures are the same.

Potential injury could result from contact with the hot light canopies or lamps.
The lamp ends near the sockets produce enough heat to cause skin burns.
Do not touch the lamps while in operation. Allow the lamps to cool before changing
5.3 Lighting Options
The chamber can be equipped with several different lighting configurations. Programmable
ranges depend on the light type selection and choice of dimming or levels control.
5.3.1 Fluorescent Lighting
The standard lighting configuration consists of fluorescent lamps to provide a balanced
spectrum for plant growth. The lighting is programmable in steps, dimmable from 10% to 100%
of maximum output.
The fluorescent tubes are individually replaceable, as required.
5.3.2 LED Lighting – LED Option
LED lighting offers significant advantages over the fluorescent lighting packages, including:
Decreased wattage consumption, which yields significant energy savings.
Reduced overall maintenance costs due to the longer life of LEDs.
Reduced heat production during operation, which reduces demand on the cooling
system and allows the light to be closer to the plants.
Reduced sensitivity to temperature variations.
LED tubes are not compatible with GEN1000 fluorescent canopies. Conversely,
fluorescent lamps are not compatible with GEN1000 LED canopies.
Contact Conviron for LED tube replacement.
5.3.3 Closed Loop Dimmable Lighting System
Lamp canopies incorporate dimmable ballasts. Automatic adjustment of the light intensity can
be set within the programmed range for as low as 10% for fluorescent and 10% for LED.
Prior to operating dimmable fluorescent lamps, run the lamps at full intensity for a period of 100
hours to burn off impurities on the filament ends of the lamps left during manufacturing process.
38 July 22, 2019 | 287960-ENG | R00
Page 49
Operation
Failure to burn in the fluorescent lamps before dimming will significantly reduce the life
of the tubes.
5.4 Aspirator
Located in the growth area, the aspirator houses the sensors used to monitor temperature and
humidity levels within the chamber. The aspirator receives an air sample from the room to
measure and control conditions and provides shielding from the chamber lighting to prevent
false readings caused by radiant energy.
Figure 5-1 Aspirator
5.5 Instrumentation Port
The instrumentation port with a threaded closure is located on the lower-right side of the
chamber (Figure 5-2). The port enables instrument probes, and small hoses, etc. to be passed
through the wall of the cabinet for connection to equipment within the cabinet growth
environment.
The instrumentation port is intended for low-voltage wires only. Conviron does not
recommend the use of extension cords inside the chamber.

GEN1000 Operator Manual
5.6 Fresh Air Inlet and Exhaust Ports
The fresh air inlet allows the operator to manually adjust the rate at which fresh air is introduced
into the chamber. The adjustment knob is located on the lower-left side of the chamber and can
be adjusted from fully closed (no fresh air) to fully open to allow up to 20 ft3/min (0.57m3/min) of
air exchange.
The fresh air inlet assembly contains a foam filter to help prevent light, dust, and larger
particulate matter from entering the growth area. This filter should be cleaned monthly to
prevent a build-up of foreign material that could restrict airflow. Refer to the Conviron Chambers
Maintenance & Troubleshooting Manual for more information.
Fresh air is drawn into the bottom of the chamber through the inlet port by the chamber’s
variable speed fan located in the ceiling compartment, and then the chamber air is exhausted
through the top exhaust port (Figure 5-3).

5.7 Fan Speed Control
Fan speed is user-adjustable between the preset minimum and the maximum allowable fan
rpm.
To adjust the fan speed:
Refer to the supplied control system manual for a complete description and operating
instructions.
5.8 Plant Placement
Depending on the chamber configuration, a wide variety of plant growth options are available,
from seed to full maturity, and for short to medium and tall plant species.
Plant pots or trays are placed directly on the wire shelves, or directly on the Unifloor in a TA
configuration.
The shelves can be installed in any position within the chamber, depending on the experiment
requirements. Refer to Section 3.6 Install the Light Canopies and Shelving Configuration Kits,
starting on page 15 for installation instructions.
5.9 Bypass Dehumidification – BDH Option
The Bypass Dehumidification (BDH) is an optional dehumidification system used to achieve
relative humidity setpoints below the resultant of ambient conditions and moisture load in the
cabinet. A precisely controlled volume of chamber air bypasses the heat exchanger by means of
a proportionally controlled air damper. Using the cooling system, moisture is removed from the
remaining air by cooling and reheating.

Close the main valve on the CO2 tank when it’s not in use.
GEN1000 Operator Manual
5.10 Additive Carbon Dioxide Control – CO2 Option
The Carbon Dioxide control option provides additive control of CO2. It includes a sensor
connected to the control system and a solenoid controlled injection system to elevate CO2 levels
in the chamber.
The level of CO2 in the chamber is displayed in parts per million (ppm) on the control screen and
is programmed the same way as temperature and humidity. CO2 is monitored continuously as
long as the control system is active.
5.10.1 Set up the Additive CO2 Control
CO2 control requires a high-pressure and a low-pressure regulator. In most chambers, the lowpressure regulator and the solenoid assembly are located above in the machine compartment
and are factory set at 2 pounds per square inch (psi).
Do not adjust this setting.
The high-pressure regulator is located on the customer-supplied CO2 line. This regulator comes
in two styles of flow meters, a dial gauge or a glass tube and ball style. In North America,
Conviron provides the high-pressure regulator. Outside North America, the customer supplies
the high-pressure regulator due to different thread sizes on the CO2 line.
Do not adjust the regulator on the CO2 tank once it has been set up.
5.10.2 Adjust the CO2 Control
There are two variables to consider: programming desired CO2 concentration and control of air
flow through the chamber.
Programming the CO2 setpoint is as easy as programming temperature or relative humidity.
Values are entered in parts per million in the CO2 zone on the Main Status Program Screen of
the control system. The Vaisala™ CO2 monitor operates in two ranges, up to 2000 ppm and up
to 3000 ppm.
Customized ranges are available upon written request. Contact Conviron for more
information.
Ambient CO2 levels are usually at least 350 ppm and can be higher, depending on proximity to
other CO2 sources such as human beings or automobiles. The CO2 concentration in the
42 July 22, 2019 | 287960-ENG | R00

Operation
chamber can never be less than the ambient concentration because CO2 control is additive
only.
Closing fresh air into and exhausting air out of the chamber is important to achieving desired
CO2 concentrations. Failure to consider this will lead to undesired results.
To adjust the CO2 control:
Refer to the supplied control system manual for a complete description and operating
instructions.
5.11 Central Management System – CMS Option
Refer to the supplied central management manual for a complete description and operating
instructions.
5.12 Shutdown
In the event that the chamber will not be used for a period of up to and including 14 days, it is
best to keep it running, with the temperature at or near ambient and with only the fans running.
If experiments will not be run for a period of longer than 14 days, to minimize unnecessary
electricity consumption, ensure all plants and soil are removed from the growth area, and clean
the unit as described in the Conviron Chambers Maintenance & Troubleshooting Manual. Open
the fresh air inlet and exhaust ports and leave the chamber and observation doors slightly open
to reduce moisture buildup.
