Premium freezers are totally free of CFCs (Chlorofluorocarbons) and HCFCs (Hydrochlorofluorocarbons). They use HFCs (Hydrofluorocarbons) as refrigerants.
3.4Features
The freezers are manufactured using high quality steel and electronics for long life. The Premium 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.
•Freezers are totally free of CFCs (Chlorofluorocarbons) and HCFCs (Hydrochlorofluorocarbons). They use industrial grade, commercially available HFCs (Hydrofluorocarbons) as refrigerants.
•Heavy-duty commercially available compressors provide rapid temperature pull-down and recovery after door opening.

Premium -86 °C Freezers — Operating manual

4.1Preparing installation
Risk of personal injury
DO NOT attempt to lift any freezer by hand. Preferred lifting for loading and unloading is by
WARNING! |
mechanical lifting equipment. |
|
|
||
|
|
|
|
Risk of material damage |
|
|
Maintenance, adjustment and repair work should be carried out only by QUALIFIED, |
|
NOTICE! |
EXPERIENCED personnel who have been AUTHORIZED to undertake such work by |
|
Eppendorf or its authorized agents. |
||
|
Failure to use authorized service agents will invalidate the warranty.
4.2Selecting the location
All freezers are mounted on castors for ease of movement. Upright freezers and chest freezers have locking front castors to stop the freezer from rolling once it is in place; locking front castors do not provide leveling adjustment, so the site chosen for the freezer must have a flat, level floor.
Position the freezer to allow disconnection to be made in respect to removal of the plug or appliance coupler, also the free air entry through the intake grille in the front and free air exit from the back. Provide a clearance of at least 150 mm (6 in) on all sides.
For efficient temperature control, the freezer should be placed in a shaded area, away from sources of excessive heat. For maximum cooling capability, the product should be located in an air-conditioned room.
4.3Mains/Power plugs and Receptacles
New Brunswick Freezers are offered with a variety of mains/power cords to accommodate local voltage requirements. To determine the mains/power receptacle required in your lab, first identify the plug we provide from the list below and check the freezer rating plate for mains/power requirements, then see the table which follows.
•All 120 V, 60 Hz freezers use plug B, with the exception of Innova U101 freezers which use plug A
•All 208 - 230 V, 60 Hz freezers use plug C
•All 230 V, 50 Hz freezers are provided with both plugs D and E

4.4Installing the shelves
Model U410, U570, and U700 freezers are fitted with four adjustable shelves. These can be positioned in 12.7 mm (½ in) steps anywhere throughout the freezer.
To effectively utilize racks within the freezer, be sure to position them so that each shelf is aligned with the bottom of each inner door.
Perform the following steps to install the shelves:
1.Ensure that the freezer is turned off and unplugged.
2.Remove the protective plastic coating from the shelf.
3.Position the four shelf clips evenly within the freezer by squeezing the clip, then inserting it into the shelf support within the freezer.
4.Place the shelf in the freezer, making sure all four shelf clips are supporting the weight of the shelf.
To readjust the shelf or shelf clips, gently squeeze the shelf clip to release it from the side of the freezer, then reposition it as needed.
4.5Lockable freezer handle
Freezers are supplied with lockable handles.
The C340 and C660 are fitted with a quarter turn key lock.
The upright freezer handle is fitted with barrel locks (push in and turn key to lock, turn key to unlock; the barrel will only lock when a key is turned to the lock position). The barrel lock may be removed from the upright freezer handle if the lock feature is not required.
An optional padlock adaptor can provide extra security by allowing the addition of a customer-supplied padlock to secure the freezer handle.
Removing the upright freezer handle barrel lock
Perform the following steps to remove the barrel lock from the upright freezer handle, if the lock feature is not required:
1.Open the freezer door and place the freezer handle in closed position.
2.Remove the two screws from behind the lock barrel.
