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 service@caronproducts.com 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.
* Depending on user set points, these units may not need a drain. Drains are
recommended at temperatures below 15°C.
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
6200 series Operations Manual Rev D 2/14/2012 Page 10 of 60
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.
6200 series Operations Manual Rev D 2/14/2012 Page 11 of 60
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.
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” 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.
For non-humidified chambers operated above 15°C, a drain is not needed. Install the
3/8” plug into the drain connection.
Connecting the Water Supply
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.
6200 series Operations Manual Rev D 2/14/2012 Page 12 of 60
Connect each chamber to a grounded circuit.
Failure to do so could result in electrical shock.
Use only distilled or deionized water with a
resistivity between 50K-CM and 1M-CM and
a pH of greater than 6.5. Using water outside
this range will void your warranty.
Do not use water that contains chloramines.
Chloramines can damage internal rubber
gaskets resulting in leaks.

Connecting Communications & Analog Outputs
This unit comes standard with features such as RS485 communications and analog
outputs. A set of terminals are provided to connect to RS485 communications and
analog outputs.
Analog Outputs
Analog outputs are either milliamps (0-20mA, 4-20mA) or voltage (0-5V, 1-5V, 0-10V,
0-20V) signal output that represents each of the displayed temperature (and humidity)
values. These options can be used for connection to in-house data acquisition,
recorder, or alarm system.
Factory default settings are as follows:
Connect shielded wires to the appropriate signal terminals: I(+) for current (mA) or V(+)
for voltage (DC). For both current and voltage outputs, COM(-) is common terminal.
The controller itself must be programmed for the voltage or current signal and
corresponding scale (see Operations Section)
Communications
6200 series Operations Manual Rev D 2/14/2012 Page 14 of 60
RS-485 communications are intended to communicate with a PC using ModBus RTU
or Standard Bus. The maximum number of chambers connected to a single PC is
limited to 247 controllers (Modbus) or 16 controllers (Standard Bus). Chambers 6221
& 6421 have one controller each. Chambers 6220 & 6420 have two controllers each.
Connect shielded wires to the RS-485 Communications terminal blocks.
Communications wires should be shielded and routed away from power wires.
Maximum distance of total wire is 2000 feet. When connecting multiple chambers,
route wires in a daisy chain fashion. A termination resistor of 120 ohms may be placed
across RS-485(-) and RS-485(+) of the last chamber in the daisy chain.
For PC’s having an RS-232 serial port (9-pin D-Sub) connection, an RS-485 to RS-232
converter may be used. Recommended sources are B&B Electronics (P/N 4850I9TB)
and CMC-Connecticut Micro Computer (ADA485L).
SFTW301 software is available from CARON to load onto a PC to monitor and record
data. This data storage is not 21CFR Part 11 compliant.

Installing the Heatless Dryer Package (DRYR301)
The Heatless Dryer Package extends the operational limits to a minimum humidity
control point of 2% RH and improves the dehumidification rate by purging the chamber
with dry air. Air flows through the Dryer Package only when dehumidification is
required to maintain the humidity set point.
It uses compressed air at 90 to 100 psig to operate. Maximum airflow required is 480
SCFH (8 CFM). Of this 300 SCFH (5 CFM) is injected into the chamber as dry air and
180 SCFH (3 CFM) is exhausted into the room after being used to regenerate the
desiccant. Particles of dirt or rust, as well as large amounts of condensed moisture or
oil that may be in the compressed air line feeding the dryer must be removed from the
air stream before it enters the dryer.
