Precautions for Safe Operation
When the CO2/LN2 backup system is activated, the installation place must be well ventilated. Increased CO2 in
the air may be harmful and even fatal. If the ventilation is poor, other methods should be considered to ensure
safe working environments.
If there is a leakage of petroleum gas or other flammable gas, close the gas supply valve and open doors and
windows to ventilate the air. Do not plug or unplug your freezer unit to avoid potential explosion or fire.
Only professional technicians
can install the unit. Failure to do so may cause electricity or fire.
The freezer must be securely installed on a firm floor. Tilted installation may result in the product tipping over,
causing injury and damage.
Only use a dedicated power supply matching the
requirement specified on the label to avoid fire and shock.
If the voltage being used is 10% higher than the rated voltage, a regulator with a capacity of 4000 W or higher
must be installed.
If the power cord needs to be extended, the cross-section of the extended cable must be no less than 2 mm² and
no longer than 3 m for products of 208V~230V/50Hz or 208V~230V/60Hz and no less than 3 mm² and no longer
than 3 m for products of 115V~/60Hz to avoid fire or electric shock.
Your ULT unit is equipped with a standard three-prong power plug (grounded) complying with the standard three-
prong socket (grounded) rated 16 A (208V~230V/50Hz or 208V~230V/60Hz) or rated 20A (115V~/60Hz). Removal
of the ground prong is strictly prohibited for safety reasons under any circumstances. The electrical power plug
should be securely plugged into the socket. A loose plug in the socket may cause fire.
The power socket intended for your ULT usage must be grounded to avoid electric shock.
If the socket does not meet this requirement, the
condition must be corrected by a qualified technician before
using the ULT unit.
Replacement of any spare parts should be performed by qualified technicians.
Never install your ULT in an unprotected area. If the unit gets wet, there is a danger of electric shock.
Your Blizzard ULT must not be installed in a damp area or an area subjected to water spray. Otherwise this may
reduce the degree of insulation which may cause electrical leakage or electrical shock.
Never directly pour water into the unit. The water may cause electric shock or short circuit.
Do not place any water container or heavy object on top of the unit. A falling object may injure an operator. If the
water spills into the unit, it may damage the insulation thereby causing electric shock.
Never use gas lines, water mains, telephone lines or lightning rods as the grounding device for your ULT unit. This
type of improper grounding may cause electric shock or other danger.
Do not touch any electrical components, switches, or power cord with wet hands. This may lead to electric shock.
When unplugging the power cord from the socket, please grip the plug itself and pull it out. Do not pull the power
cord as this may strip the wires out of the plug thereby causing electric shock and fire.
Should
there be any malfunction in the equipment, power off the unit and unplug the power cord from the power
supply. Continuous operation in an abnormal condition may result in electric shock and fire.
Never disassemble, repair, or modify the unit yourself. Any such work carried out by an unauthorized person may
result in fire, or electric shock or injury due to a malfunction.
Before any repair and maintenance of the freezer, please disconnect the power to avoid electric shock or injury
to personnel.
