CHAPTER 1 | PRECAUTIONS
• Qualied trades-people such as electricians, plumbers, refrigeration mechanics, etc.
should perform all work as required by local codes and regulations.
• Central Management™ (CM) is an optional feature. If CM is being used it becomes
inextricably linked to the use of the Controller and therefore, both the Central
Management manual and the Controller Operators Manual must be read and
understood in their entirety prior to operation.
• Working with high voltage will be required when installing this equipment. Do NOT
attempt this work unless you have the appropriate knowledge and experience. Take
appropriate safety precautions and ensure that the building power supply to the
chamber is off prior to installation.
• The main terminal in the control panel has live voltage unless the external breaker is
OFF. Use extreme caution when working in the control panel to prevent injury.
• Water that could come in contact with the electrical components presents a high
voltage hazard. Avoid these conditions. If you have any doubt of safe watering
practices, contact Conviron.
• Controller may come equipped with an optional Uninterrupted Power Supply (UPS)
such that power will remain live for a period of time even if the power supply is turned
OFF. Use extreme caution when working on the control panel to prevent injury. If you
have any doubts as to whether your unit comes equipped with a UPS, contact Conviron.
• Inside the control panel is an independent temperature shut-off device called the
ir33. This ir33 acts as a secondary fail-safe protector that shuts off the chamber if its
temperature limits are exceeded. The ir33 is set by Conviron and is factory protected
(requires Access Level 3). The factory default setting for the ir33 temperature limit is
ten degrees beyond the chamber operating range. The standard operating range of a
chamber is +4˚C to +45˚C while the standard ir33 shut down settings are -6˚C to +55˚C
depending on the size of the chamber, size of the compressor and other factors. Always
verify, when changing the (Alarm) Temperature within the 6050 setup, that the limits
are still within the minimum and maximum operating limits for the Chamber. This will
ensure that the ir33 only triggers in the event that the actual temperature exceeds the
Chamber's minimum or maximum temperature limit by 10 degrees. It will also ensure
that the ir33 does not trigger before a high or low temperature tracking alarm. The ir33
is located inside the control panel where there is live high voltage. Contact Conviron
Client Services for more information or help if necessary.
• Surfaces and lighting may become hot during operation. Always take appropriate
precautions and do not operate if users will remain inside the chamber for more
than a few minutes unless adequate shielding or other safety precautions are taken.
NOTE: HID lamps can cause serious skin burn and eye inammation from short-wave
ultraviolet radiation if the lamp envelope is punctured or broken.
• Operators should note that water may accumulate on the oor which could be slippery
and pose a safety hazard. Always ensure oors remain dry and wear non-slip footwear.
