This manual covers the following freezer models:
All the above mentioned HEF and G freezers are totally free of CFCs (Chlorofluorocarbons) and
HCFCs (Hydrochlorofluorocarbons). They use HCs (Hydrocarbons) as refrigerants.
The following HEF freezer models utilize HFCs (Hydrofluorocarbons) as refrigerants, and are
offered for the United States market.
3.4 Features
The freezers are manufactured using high quality steel and electronics for long life. The HEF and
G-Series 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.
• Heavy-duty commercially available compressors provide rapid temperature pull-down and
recovery after door opening.
