3.4Features

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 CO2/LN2 back-up systems, remote monitoring systems, external voltage stabilizer, inventory racking, and more.

4Installation

4.1Preparing installation

Risk of personal injury

DO NOT attempt to lift any freezer by hand. Preferred lifting for loading and unloading is by mechanical lifting equipment.

WARNING!

Risk of material damage

Maintenance, adjustment and repair work should be carried out only by QUALIFIED, EXPERIENCED personnel who have been AUTHORIZED to undertake such work by New

NOTICE!	Brunswick Scientific 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. The U101 upright freezer has two rear wheels. Upright freezers have feet that provide both a leveling feature and a locking feature to stop the freezer from rolling once it is in place. Chest freezers have locking front castors; these 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.

4.3Installing the shelves

Model U101 upright freezers are fitted with one fixed shelf. Model U535 and U725 upright freezers are fitted with two 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.

4.4Lockable freezer handle

Freezers are supplied with lockable handles.

The U101, C585, and C760 are fitted with quarter turn key locks.

The U535 and U725 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.
