Page 14: Freezer Handles
Figure 1: Model U360 Upright Freezer—Side & Front Views 2.1.1 Freezer Handles The freezers are supplied with lockable handles. The U101, C585 and C760 models are fitted with quarter turn key locks. The U360, U535 and U725 upright freezer handles are fitted with push-barrel locks (push in & turn to lock, turn key to unlock). An optional padlock adaptor can provide extra security by allowing the addition of a customer-supplied padlock to secure the freezer handle. -
Page 15: Installation & Setup
Maintenance, adjustment and repair work should be carried out only by QUALIFIED, EXPERIENCED personnel who have been AUTHORIZED to undertake such work by New Brunswick Scientific or its authorized agents. Failure to use authorized service agents may invalidate the warranty. -
Page 16: Shelf Installation
Position the freezer to allow free air entry through the intake grille and free air exit from the back; a clearance of at least 6 inches (150 mm) on all sides is recommended to prevent heat build-up in the compressor housing. The grille is located on the front of both chest and upright models (see Figure 1). -
Page 17: Installing The Power Cord
The freezer’s compressor will not operate for approximately one minute after connection of the power supply, because there is an automatic delay device in the circuit. Temperature and alarm settings, however, can be adjusted immediately. New Brunswick Scientific User’s Guide... -
Page 18: Alarm Activation & Alarm Battery Charging
Alarm Activation & Alarm Battery Charging The equipment is delivered with the audible alarm & alarm battery deactivated. The black battery rocker switch behind the lockable power switch panel activates the alarm I (ON) O (OFF) system battery. The switch is labelled To activate the audible alarm and to charge the alarm battery, place the battery switch in I (ON) position. -

4.4.5 Alarm Socket Delay ALARM SOCKET DELAY , programmable from 5 to 180 minutes, allows you to delay the activation of the alarm monitoring socket during a temperature alarm. New Brunswick Scientific User’s Guide... -
Page 26: Alarm Mute & Acknowledgment
When a temperature alarm is activated, alarm socket activation will be delayed for the programmed period. If the alarm condition is still active after the delay period, the alarm socket will activate (see Section 4.4.5 for more information). In the case of a power failure or any non-temperature-based alarm (e.g., a sensor failure), the alarm socket will activate immediately, and the delay period will be ignored. -
