Innova® -86 °C Freezers — Operating manual
3.4 Features
The freezers are manufactured using high quality steel and electronics for long life. The cabinets
are insulated with a combination of foamed-in-place polyurethane foam and vacuum insulation
panels. This combination ensures superior insulation properties while maintaining an extra large
internal capacity for the footprint of the freezer. The Innova freezers have many features designed
to provide ease of use and maintanence, security and reliability to your ultra-low temperature
storage needs. They are built to stringent regulatory requirements for safety and environmental
friendliness and disposability, and they are CE and UL certified.
Features include:
• Designed to be exceptionally energy efficient and eco-friendly.
• A setpoint keypad and digital temperature readout are provided on a control panel, located on
the door of the upright freezers and on the console on the right side of chest freezers.
Controls for setting the freezer temperature and alarm warning setpoints are enabled by an
electronic lock. A unique code, which is selected by the user through the keypad, sets this
lock. The code can be changed at any time, provided the current setting of the lock is known.
On delivery, the lock code is "0000" (unlocked).
• Indicator lamps on the control panel provide warnings of power loss, system failure,
exceeding High/Low temperature setpoints, low battery voltage, and filter blockage. There is
also an LED to indicate when the freezer is under remote control via the RS-485 optional
computer interface.
• Vacuum insulation panel technology reduces the cabinet wall thickness while maintaining
superb insulation characteristics to provide the largest internal volume per floor space used.
• Freezers are totally free of CFCs (Chlorofluorocarbons) and HCFCs
(Hydrochlorofluorocarbons). They use industrial grade, commercially available HFCs
(Hydrofluorocarbons) as refrigerants.
• Upright models utilize gasketed and insulated inner doors to reduce cold air loss and recovery
times, reduce internal temperature fluctuations and conserve energy. Chest models utilize
insulated covers to reduce internal temperature fluctuations and conserve energy.
• Heavy-duty commercially available compressors provide rapid temperature pull-down and
recovery after door opening.
• A heated port with ice-clearing plunger prevents vacuum formation enabling the outer door to
be easily opened at anytime.
• All interior panels and shelves are made of high grade corrosion-resistant stainless steel,
making them durable and easy to keep clean and sterilize.
• Inner doors lift off their hinges without the use of tools to simplify cleaning.
• Heavy duty castors enable easy installation and relocation (the model U101 has rear rollers
and adjustable front legs.)
• Two access ports allow easy addition of sensors, or of back-up systems that can provide
cooling protection for your samples in the case of a power outage or other system failure.
• An alarm contact is provided for connection to an external monitoring device or system.
• The freezers can be fitted with an optional 7-day circular chart recorder to provide
independent temperature recording.
• An automatic reset restarts freezers at random 15 second intervals to protect the
microprocessor controller from damage by electrical spikes caused by multiple freezers
turning on at once.
• Lockable freezer handles on outer door provide added security against unauthorized users.
• An internal voltage stabilizer (60 Hz models only, except U101) that automatically
compensates for variations in mains/power supply voltage (in case of over-voltage,
brown-outs, dips, sags and surges).
• Multiple accessories are offered, including CO
