When a CO
/LN
backup system is activated, the installation place must be well ventilated.

2
Increased CO
in the air may be harmful and even fatal. If the ventilation is poor, other methods
2
should be considered in order to ensure safe working environments.
If there is a leakage of petroleum gas or other fl ammable gas, close the gas supply valve and
open doors and windows to ventilate the air. Do not plug or unplug your freezer unit in order to
avoid potential explosion or fi re.
Only professional technicians or Haier service personnel can install the unit. Failure to do so
may cause electricity or fi re.
The freezer must be securely installed on a fi rm fl oor. Tilted installation may result in the product
tipping over thereby causing injury and damage.
Please use the dedicated power supply marked on the product label to avoid fi re and electric
shock.
If the voltage being used is 10% higher than the rated voltage, a regulator with a capacity of
4000W or higher must be installed.
If the power cord needs to be extended, the cross-section of the extended cable must be no less
2
than 2mm
and no longer than 3 m for products of 220V~240V/50Hz or 220V~/60Hz and no less
2
than 3mm
and no longer than 3 m for products of 115V~/60Hz to avoid fi re or electric shock.
Your Haier ULT unit is equipped with a standard three-prong power plug (grounded) complying
with the standard three-prong socket (grounded) rated 16 A (220V~240V/50Hz or 220V~/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 fi re.
The power socket intended for your Haier ULT usage must be grounded to avoid electric shock.
If the socket does not meet this requirement, the condition must be corrected by a qualifi ed
technician before using the ULT unit.
The replacement of any spare parts (battery etc.) shall be conduct by technicians approved by
manufacturer.
Never install your ULT in an unprotected area. If the unit is rained on, there is a danger of
electric shock.
Your Haier ULT must not be installed in a damp area or an area subjected to water spray.
Otherwise this may reduce the degree of insulation and thereby 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 lightening rods as the grounding device for
your Haier 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. Such action
may lead to electric shock.
