SECTION 3 – INSTALLATION

This product weighs in excess of 700 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 service@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 set points, these units may not need a drain. Drains are recommended at temperatures below 15°C. Units with optional humidity control (HUMD302 & HUMD303) 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.

Preliminary Cleaning

Your new plant growth 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 7300 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 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.

7300 Series Operations Manual Rev A 3/26/2014 Page 11 of 80

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.

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

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 1/2” 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.

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.

7300 Series Operations Manual Rev A 3/26/2014 Page 12 of 80

Connect each chamber to a grounded circuit. Failure to do so could result in electrical shock.

With the purchase of ALRM302, a set of terminals on the rear of the unit is provided to monitor temperature, 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.

7300 Series Operations Manual Rev A 3/26/2014 Page 15 of 80

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 (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 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.

7300 Series Operations Manual Rev A 3/26/2014 Page 16 of 80

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 the Water Supply (HUMD302 & HUMD303)

Tubing to water inlet

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.

A water inlet fitting on the back of the unit and ¼” black tubing are provided to connect the water supply to the chamber. Connect an appropriate water supply to the fitting. Incoming line pressure should be regulated to not exceed 80 psi.

If a Condensate Recirculator water recycling system was purchased as a water supply, refer to its user’s manual for proper installation of the water supply.

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 set point 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.
