SECTION 3 – INSTALLATION

This product weighs in excess of 500 pounds.
Ensure that sufficient resources are available to
safely move the product.

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 [e-mail] for details.

Choosing a Location

To ensure proper operation, the unit must be located on a firm level surface, capable of
supporting approximately 800 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.

All units have temperature control and need a drain for refrigeration condensation. For
units with the humidity control option, a water source is also needed.

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 weblink for information on the product:

http://www.caronproducts.com/65

6320 & 6340 Series Operations Manual Rev G 9/16/2013 Page 12 of 61

Each shelf is capable of supporting a uniformly
distributed load of 50 pounds. The maximum
chamber capacity is 500 pounds (stationary). An
optional re-enforced floor is available for heavy loads.
Chamber should be empty when being moved.

Do not have multiple loaded shelves out
simultaneously or the chamber may tip.

Preliminary Cleaning

Your new environmental chamber was thoroughly cleaned prior to leaving the factory.
It is recommended however, to disinfect all interior surfaces with a general purpose
laboratory cleaning agent 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 environmental chamber includes four or five 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 size 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.

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.

6320 & 6340 Series Operations Manual Rev G 9/16/2013 Page 13 of 61

Leveling the Unit

When using a pressurized water source, failure
to connect the unit to a drain could result in
facility flooding.

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.

Place a level on the middle shelf of the chamber. 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” NPT fitting and tubing are supplied in the unit parts kit. Thread the
fitting into the drain connection and 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.

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.

Connecting Alarm Contacts (ALRM301)

With the purchase of ALRM301, a set of terminals on the rear of the unit is provided to
monitor temperature and humidity (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.

Humidified models can be purchased with an optional 2.5 gallon carboy water system.
The carboy system is preassembled and shipped inside the chamber. The four ¼”
bolts required to mount the carboy to the unit will be mounted in the left hand side of
the chamber. Remove the carboy assembly from inside the chamber and attach it to
the chamber using the ¼” bolts.

Attach the preassembled tubing provided with the carboy to the water inlet on the rear
of the chamber.

Fill the carboy with water as described in the “connecting a water supply” section of the
manual.

High concentrations of carbon dioxide can
cause asphyxiation. The use of CO2 monitors
and alarms is recommended for areas where
CO2 can collect.

The CO2 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 CO2 supply (CO2C301)

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 CO2 gas supply. Check the
connections closely for leaks.

If the unit is equipped with a built in gas guard system, there will be 2 gas inlets. Each
of the inlets should be connected to an individual gas tank as described above.
