10.1 Backup Protection Devices
Liquid Nitrogen and Liquid CO
2
systems are available to protect
your product in case of a prolonged power failure. These systems
are powered by a rechargeable battery with a built-in automatic
charger. Refer to Section 6.3.4 on page 7 for additional
information.
10.1.1 Liquid Nitrogen (LN
2
)
This system uses portable and locally refillable bottles. These
containers keep the liquid at low temperature and pressure by
continually venting a small amount of gaseous N
2
. You must
check the liquid level indicator daily to assure an adequate
emergency supply.
10.1.2 Liquid CO
2
This system uses portable and locally refillable bottles that are
not vented and have a virtually unlimited standby life unless they
develop a leak. These containers hold liquid at room temperature
and high pressure. Several bottles can be connected together,
increasing the effective length of standby refrigeration.
10.1.3 Voltage Safeguard
This fully automatic device monitors the supply voltage and
increases voltage if necessary so the freezer always operates
within the factory recommended limits. Ultima II models are
factory equipped with this device.
CAUTION!
The Voltage Safeguard unit does not
allow you to operate a 115 volt product on 230 volts or
vice versa. It is designed to provide 5 to 15% voltage
correction, depending on the freezer model.
10.2 Remote Alarm
The remote alarm terminals on the back of the freezer are
connected to freezer internal dry contacts. You can connect a
remote alarm package with a separate 24 volt power supply.
