SECTION 3 – 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.
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: http://www.caronproducts.com/65 Preliminary Cleaning Your new environmental chamber was thoroughly cleaned prior to leaving the factory.
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 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. 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.
SECTION 4 – 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 and humidity (model 7001) 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.
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).
Incoming compressed air must not exceed 100 psig. CARON recommends installing a pressure gauge, filter, and shutoff prior to the dryer to monitor incoming air pressure. The air supply (either house air or other compressed air source) must be 90 to 100psig at the air supply inlet. An oil-less compressor may be used. A Sound Suppression Kit maybe used to reduce the dryer noise (contact CARON service for details). 1. Attach Dryer Package to exterior chamber with four mounting screws.
3. Attach 3/8” orange tubing from the chamber to the flow meter outlet. Flow Meter Outlet 4. Connect compressed air to dryer package inlet fitting (1/4 NPT) Dryer Inlet See Operations section of the manual for instructions on setting the pressure regulator and flow meter.
Connecting Analog Outputs (OUTP301, OUTP302) With the purchase of OUTP301 or OUTP302, 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 Output Connections Analog outputs as either milliamps (4-20mA) or voltage (0-5V) 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.
Installing Drain Water Pump (PUMP301) In applications where a floor drain is not available and a CARON water recycling system is not being used, a drain pump can be purchased to pump any excess condensate from the chamber to a local sink or drain. The pump is located near the middle of the back of the chamber. Connect the supplied tubing from the pump to the sink / drain. The tubing may be run vertically into a ceiling but should not exceed 15 feet height.
SECTION 5 – OPERATION With the chamber properly installed and the appropriate utilities connected, the power switch on the right side top wrap can be turned on. Within a few minutes, the temperature and humidity will begin to approach set-points. Here is an overview of the home screen.

The two-pen model accepts inputs from a temperature sensor and a humidity sensor. The single-pen model records temperature only.
SECTION 7 – CALIBRATION The temperature and humidity systems can all be calibrated as necessary. CARON recommends an annual calibration check of each system. Before making a calibration adjustment, allow the cabinet to stabilize a minimum of 12 hours from a power off condition. If the unit has been in operation, allow a minimum of 3 hours of stable operation at all set-points.
Calibrate Button Once the settings screen appears, press the (Calibrate) button.
Calibrating the Temperature If temperature calibration is needed, the following steps can be taken: Locate the reference instrument’s temperature sensor in close proximity to the cabinet’s geometric center. Be sure that the stabilization times described earlier have been satisfied prior to performing calibration. Temperature Calibrate Button At the calibrate screen, press the (Temperature Calibrate) button. Keypad Enter the temperature offset by using the keypad and pressing complete.
Temperature calibration (example) If the chamber temperature display reads 40.0C and the calibrated independent sensor shows 40.3C, set the temperature offset value to 0.3C. If the calibrated independent sensor shows 39.6C, then the entered offset should be negative. In this example the required offset to temperature would be -0.4C.
SECTION 8 – ALARMS Alarm System Overview The chamber control system is equipped with an alarm system that constantly monitors temperature, and humidity (on humidified models) to ensure the user is notified if the cabinet goes into an alarm condition. Notification occurs via an alarm pop-up window and a buzzer. Each alarm condition has been factory programmed to minimize nuisance alarms while maximizing warning time. There is a 2 hour time delay at startup and set point changes.
