LED lights are bright. Avoid looking directly at them. Use
protective eye wear or serious eye damage may occur.
LED Light Banks
The standard units come with white LED lights. If one of the optional light configurations
is purchased, it may contain a combination of the 4 colors: red, white, blue and far red
(infra-red) Far-red LED light for plant growth is much dimmer than the rest. The human
eye can only see to about 700 nm and the far red peaks in the 720-740 nm LED.

INSTALLATION
Unpacking
Your new unit has been thoroughly packaged to avoid shipping damage. However, the
unit should be fully inspected upon arrival before signing for receipt. If the package has
visual damage, notes should be made on the freight bill and signed by the delivery
company. In the event of concealed damage after the unit is uncrated, keep the carton
and packaging material. Call the shipping company within 7 days of receipt, request
inspection and retain a copy of the inspection report.
Caron provides full on-site installation services for all models. Our installation services
guarantees the proper set-up and startup of all equipment. Please contact the Service
Department at 740-373-6809 or www.caronproducts.com for details.
For detailed instructions on how to safely remove the chamber off the shipping pallet,
see document located on the chamber.
Choosing a Location
To ensure proper operation, the unit must be located on a firm level surface, capable of
supporting approximately 1,000 pounds. The unit should be located in an 18°C – 25°C
ambient area and where there is no direct airflow from heating and cooling ducts as well
as out of direct sunlight.Allow four inches of clearance on all sides of the product to
allow for connections and airflow.
Depending on user setpoints, these units may not need a drain. Drains are
recommended at temperatures below 15°C. Units with optional humidity control
(HUMD312, HUMD313 & HUMD314) need a water source and drain.
The unit requires a dedicated electrical connection. Power requirements vary depending
upon the chamber model, see Connecting Electrical Power section.
Choose a location where these facilities are, or can be made available. If a water
source or a drain is not available, contact Caron customer service and ask about our
CRYS102 product line or click this web link for information on the product:
www.caronproducts.com
This product weighs in excess of 700 pounds.
Ensure that sufficient resources are available to
safely move the product.

7310 Series Operations Manual REV E 11-19-19 Page 13 of 131
Preliminary Cleaning
Your new Plant Growth chamber was thoroughly cleaned prior to leaving the factory. It
is recommended, however, to clean all interior surfaces with a general purpose
laboratory cleaning agent to remove any shipping dust or dirt prior to using the product.
After cleaning, dry all interior components with a sterile cloth as necessary.
Installing the Port Stoppers
The unit has an access port built into each side of the cabinet. The ports are designed
to allow customer access for equipment validation and for installation of other equipment
inside the chamber. These ports should be sealed with the provided rubber stoppers to
allow the chamber to function properly. Install the stoppers provided in the port on each
side of the unit.
Installing the Shelves
Each new 7310 Series Plant Growth Chamber includes perforated stainless steel
shelves. Each shelf requires two shelf channels for installation. The left and right shelf
tracks are the same. Prior to installation, take time to consider what the height of the
product being placed in the chamber will be and set the shelf spacing accordingly.
Additional shelving can be purchased through Caron customer service if necessary.
The chamber should be empty when being moved.
To install the shelf channels insert the rear tab on the shelf channel into the rear wall on
the side wall of the chamber. Then insert the front tab into the front pilaster. Push the
entire shelf channel towards the rear of the unit and snap it down into place.
Each empty shelf is capable of supporting a uniformly
distributed load of 50 lbs / 22 kg. Each shelf which also
holds a light bank underneath is capable of supporting a
uniform distributed load of 25 lbs/ 11 kg.
The maximum chamber weight capacity (stationary) is:
180 lbs / 82 kg (1-door),
200 lbs / 91 kg (2-door)
300 lbs / 136 kg (3-door).

7310 Series Operations Manual REV E 11-19-19 Page 14 of 131
Leveling the Unit
Place a level on the middle shelf of the incubator. Adjust the feet until the unit sits level
left to right and front to back. Even if the unit is level without adjustment, the leveling
feet should still be lowered to avoid the cabinet moving while opening and closing the
outer door & prevent a flat spot from forming on the casters.
Connecting the Drain Line
The chamber drain connection is located in the bottom middle of the back of the
chamber. A 3/8” tube fitting and tubing are supplied in the unit parts kit. Slide the tubing
into the drain connection. Pull on the tubing after installation to make sure it is tight.
Route the drain tubing to a local floor drain.
When using a pressurized water source, failure to connect
the unit to a drain could result in facility flooding.
Do not have multiple loaded shelves out simultaneously or
the chamber may tip.

7310 Series Operations Manual REV E 11-19-19 Page 15 of 131
If a local floor drain is not available, a variety of accessories are available through Caron
customer service. These accessories can also be viewed at www.caronproducts.com.
For non-humidified chambers operated above 15°C, a drain is not needed. Install the
1/2” plug into the drain connection.
The drain line relies on gravity to remove water from the
chamber. The drain line must remain below the chamber
to drain properly. Kinks or elevations in the drain line
above the cabinet drain will not allow the chamber to drain.

7310 Series Operations Manual REV E 11-19-19 Page 16 of 131
Connect each chamber to a grounded circuit.
Failure to do so could result in electrical shock.
Connecting Electrical Power
The unit requires a dedicated electrical outlet. See table below for model specific power
required and connection. This covers 7310,7311,7312,7315 and 7317 model numbers.

Led lights should only be used in a non-condensing
environment.
Connecting the Led Lighting
Plant Growth Chambers with LED lighting have light banks consisting of 2, 9 or 24 LED
clusters on each bank. The LED banks are suspended under each shelf. The light banks
are shipped fully installed in place and wired from the factory. See the Operations or
Maintenance sections of the manual for more details.

OPTIONAL ACCESSORY INSTALLATION
Connecting Alarm Contacts (ALRM302)
With the purchase of ALRM302, a set of terminals on the rear of the unit is provided to
monitor Temperature, Lights, Humidity (optional), CO2(optional) alarms.
With the alarm contacts, the terminals provided allow for a NO (normally open) output, a
NC (normally closed) and COM (common) connection. In the event of an alarm
condition or power failure, the NO contact will close, and the NC contact will open. Once
the alarm is cleared, the contacts return to their normal conditions. Insert the
appropriate wire into the terminal and tighten down the screw terminal on top of the
connector.

High concentrations of carbon dioxide can
cause asphyxiation. The use of CO2monitors
and alarms is recommended for areas where
CO2can collect.
The CO
2
gas supply should be 99% pure and
should not contain a siphon tube. Gas pressure
to the unit must be regulated to 15-20PSI.
Failure to do so could cause tubing to burst.
Connecting a CO2supply (CO2C302)
The CO2 supply should be 99% and not have siphon tubes. CO2 pressure should be
regulated to 15-20 psi. CO2 tank regulators can be purchased through Caron customer
service. Once the cylinder regulator is installed, connect the outlet of the regulator to the
hose barb fitting using the tubing and clamps provided. An inline HEPA filter is provided
to remove any contaminants in the CO2gas supply. Check the connections closely for
leaks.

7310 Series Operations Manual REV E 11-19-19 Page 20 of 131
Do not use water that contains chloramines.
Chloramines can damage internal rubber
gaskets resulting in leaks.
Use only distilled or deionized water with a
resistivity between 50KΩ-CM and 1MΩ-CM and
a pH of greater than 6.5. Using water outside
this range will void your warranty.
Connecting the Water Supply (HUMD312, HUMD313 & HUMD314)
HUMD312, HUMD313, HUMD314 control humidity from ambient to 85%,and dehumidify
with ambient air. To ensure proper operation, distilled or deionized water is required as a
supply on units that have humidity control. If these water sources are not available
contact Caron customer service.
