Page 10: Precautions
The equipment is intended to be installed, operated, maintained, and serviced only by trained personnel, following the instructions and precautions described in the manuals provided by Conviron. The following precautions are intended to help guide users in the safe operation of Conviron chambers. Hazard Identification Symbols... -
Page 11: General
Operate your Conviron equipment for a minimum of five days before introducing any research material to ensure proper and stable operation. - Page 12 Precautions Do not touch the lamps. Fluorescent lamps operate at high temperatures and present a burn hazard. Do not touch the lamp holders. The heated metal and glass presents a burn hazard. Ceramic metal halide and high pressure sodium lamps operate at very high temperatures.

Page 17: Start Up
Start Up START UP Once the cabinet is assembled, leveled, and all connections have been made, the cabinet can be powered on. Verify that the cabinet is operating properly before introducing any research material. Power ON Before powering on the system: ... - Page 18 Start Up 4.1.1.2 Visual Checks Check that all lights function when turned on and that the doors are light tight. Inspect the doors with interior lights on, in a darkened room. Check the evaporator fan for free movement. Some chambers have a separate breaker for fans.

With the control system powered up, set and run a program. Refer to the supplied control system manual for further details. Operate your Conviron equipment for a few days before introducing any plant material. This acquaints you with the equipment’s operation and ensures the equipment meets the requirements for your experiments. - Page 20 Check that all lights function when turned on and that the doors are light tight.

Page 21: Operation
Operation OPERATION The following sections provide an overview of the basic operation of the chamber. Fluorescent and Incandescent Combination Lighting A typical lamp loft includes fluorescent and incandescent lamps. However, other types of lamp configurations are available. Fluorescent lamps should be changed regularly, as intensity diminishes with use. -
Page 22: Unifloor
Operation 5.2.1 Unifloor® Plant materials, in pots or trays, are placed directly on the Unifloor and do not need to be moved during the experiment. Excess irrigation water will drain into the drain pan below the Unifloor and then be channeled out of the chamber to the floor drain. Figure 5-1: Unifloor To ensure proper airflow and water drainage, keep the vents and drain channels in... -
Page 23: Instrument Ports
The ports enable instrument probes, and small hoses, etc. to be passed through the wall of the cabinet for connection to equipment within the cabinet growth environment. The instrument ports are intended for low-voltage wires only. Conviron does not recommend the use of extensions cords inside the chamber. -
Page 24: Fresh Air Inlet And Exhaust Port
Operation Fresh Air Inlet and Exhaust Port The fresh air inlet allows the operator to manually adjust the rate at which fresh air is introduced into the chamber. The threaded collar is located on the front of the machine compartment and can be adjusted from fully closed (no fresh air) to fully open to allow up to 30 ft /min (0.84m /min) of air... -
Page 25: Airflow
Air is drawn over the refrigeration coil or heaters and circulated throughout the chamber. Fresh air may also be introduced, if required. Figure 5-5 BDR16 Air Flow Control exhaust is adjusted using the exhaust damper control in one of the following three modes: Automatic: The position of the exhaust damper is based on the CO setpoint. -
Page 26: Aspirator
Operation Aspirator Located in the growth area, the portable aspirator houses the sensors used to monitor temperature and humidity levels within the chamber. The aspirator receives an air sample from the room to measure and control conditions and provides shielding from the chamber lighting to prevent false readings caused by radiant energy. -
Page 27: Lighting Options
Reduced heat production during operation, which reduces demand on the cooling system and allows the light to be closer to the plants. Reduced sensitivity to temperature variations. Contact Conviron for LED bar replacement. October 2018 | 287849-ENG, R00... -
Page 28: Closed Loop Dimmable Lighting System
Operation 5.9.3 Closed Loop Dimmable Lighting System Lamp canopies incorporate dimmable ballasts. Automatic adjustment of the light intensity can be set within the programmed range for as low as 10% for fluorescent, 10% for LED, or 30% with HID lamps, to the maximum intensity. Incandescent lamps are controlled in light levels. Prior to operating dimmable fluorescent lamps, run the lamps at full intensity for a period of 100 hours to burn off impurities on the filament ends of the lamps left during the manufacturing process. -
Page 29: Ultrasonic Humidification System (Ush)
Refer to the supplied control system manual for a complete description and operating instructions. A psychotropic chart showing the operation envelope of the chamber may be beneficial during normal operations. Contact Conviron for more information. 5.10.2 Ultrasonic Humidification System (USH) This optional additive humidification uses vibrating discs to generate soundwaves underneath the surface of the water, forming a fine mist of vapor that is absorbed by the flow of air. -
Page 30: Additive Carbon Dioxide Control
The high-pressure regulator is located on the customer supplied CO line. This regulator comes in two styles of flow meters, a dial gauge or a glass tube and ball style. In North America, Conviron provides the high-pressure regulator. Outside North America, the customer supplies the high- pressure regulator due to different thread size on the CO line. -
Page 31: Adjusting The Co
Main Status Program Screen. The Vaisala™ CO monitor operates in two ranges, up to 2000 ppm and up to 3000 ppm. Customized ranges are available upon written request. Contact Conviron for more information. Ambient CO levels are usually at least 350 ppm and can be higher, depending on proximity to other CO sources such as human beings or automobiles. -
Page 32: Co 2 Scrubber
Operation 5.11.3 CO Scrubber The CO Scrubber system is a standalone device for controlling CO concentration levels below resultant conditions down to below ambient ppm levels. Chamber air is passed over an absorbing media thereby removing CO content from within the controlled environment. 5.12 Central Management System Refer to the supplied central management manual for a complete description and operating instructions. -
