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.
For prolonged periods of inactivity leave the unit unplugged and securely stored.
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 600 pounds. The unit should be located in an 18°C to 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. The unit is designed to be used under the following
conditions:
 Indoor use only
 Altitude up to 2000m.
 Maximum relative humidity: non-condensing
 Mains supply voltage fluctuations up to +/- 10% of the nominal voltage;
damage may occur if voltage varies more than 10%
 Transient overvoltages up to the levels of overvoltage category II
 Temporary overvoltages occurring on the mains power supply
 Pollution degree: 2
 Ingress protection: IPXO
This product weighs in excess of 600 pounds.
Ensure that sufficient resources are available to
safely move the product.

7800-25 Series Operations Manual Rev B 11-10-2020 Page 12 of 56
The unit requires a dedicated electrical connection. Power requirements vary depending
upon the chamber model, see Connecting Electrical Power section. If you have
questions contact Caron Service Department at www.caronproducts.com
Preliminary Cleaning
Your new 7800 H2O2 Sterilization 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.
Contact Caron if there is any doubt of the compatibility of the cleaning agent being
used with the chamber. After cleaning, dry all interior components with a sterile cloth
as necessary.
Installing the Shelves
Each new 7800-25 Series H2O2 Sterilization chamber includes 4 wire 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.
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.
Shelf capacity: each wire shelf is capable of supporting a
uniformly distributed load of 20 lbs, maximum chamber
capacity is 500 pounds (stationary).
Optional shelving is available for supporting heavy loads up to
50 or 150lbs.
Chamber should be empty when being moved.
Do not have multiple loaded shelves out simultaneously or
the chamber may tip.

7800-25 Series Operations Manual Rev B 11-10-2020 Page 13 of 56
Leveling the Unit
Place a bubble level on the middle shelf of the chamber. Adjust the leveling 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.

7800-25 Series Operations Manual Rev B 11-10-2020 Page 14 of 56
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.

When the required electrical connection is available, plug the provided power cord into
the unit and the electrical outlet.
The mains power supply cord must meet the requirements listed
above. The use of an inadequate mains power supply cord
could result in equipment failure or personal harm to the user.
In the event of a power outage the unit will automatically restart
when the power is restored. There are built safeties that will not
allow the door to be opened until chamber conditions are at a
safe level.

Connecting Alarm Contacts
With the alarm contact feature, a set of terminals on the rear of the unit is provided to
monitor temperature and humidity 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.

Connecting Analog Outputs
With the analog output feature, the controls are equipped with analog outputs. A set of
terminals are provided on the back of the unit to connect to analog outputs.
Analog outputs provide either a milliamps (4-20mA) or voltage (0-5V) signal output to
represent each of the displayed temperature humidity and H2O2 values. These options
can be used for connection to in-house data acquisition, recorder, or alarm system. The
temperature parameter (only) is adjustable in its scaling and is accessable at the Analog
Output screen.

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.

OPERATION
Before the chamber can be commissioned for use, make sure that the following steps
have been completed:
- Chamber is properly installed and level.
- The appropriate power connected to the chamber.
With the above mentioned steps complete, the power switch located on the right side,
near the top of the unit exterior, can be turned on.

Using the Keypad
This control system uses a numeric keypad to enter all parameter values. Similar to a
calculator, this allows quick and precise entry of values. When any numeric value button
is pressed, the keypad display will pop up over the current display.
The Parameter Description Header tells what parameter is being changed.
The Keypad Display shows allowable values of the parameter being changed (initially)
and displays the entered value (when a button is pressed).
The Escape “Esc” button aborts the entry and returns to the previous screen without
changing the value. The Clear “Clr” button erases the value that you have entered. After
you have entered the value that you want, pressing the Enter “Ent” button and the new
value will take affect. This also closes the keypad window. Other keypad buttons include
a decimal point button and negative button.
If an invalid numeric button is pressed such that it would create an entry above the
parameter’s range, the entered number will not display. For example, if the temperature
setpoint range is 5.0 to 70.0, pressing ‘8’ followed by an ‘0’, only the ‘8’ will display.
If an invalid entry is made with an entry below the range (such as a ‘4’ followed by the
‘Ent’ button), then the entry will clear and the range will be re-displayed.

Learning the Touchscreen
To save power and ensure long product life, the touchscreen display has a few features
that can be changed to reduce screen brightness and initiate a Screen Saver mode.
High / Low button : high or low screen brightness, preset values.
Screen Saver : By pressing the Screen Saver button “on” this will
automatically enter screen saver mode after 15 minutes. At this time, the screen will be
completely blank (ie. black). The illuminated Caron logo (see Equipment Overview
section) shows that the unit is powered on and functioning. To wake-up the touchscreen,
simply press anywhere on the touchscreen and the main screen will display. If the unit
has an alarm condition, the touchscreen will not go into screen saver mode. If an alarm
condition occurs while in screen saver mode, the display will automatically wake up and
display the alarm.
