Electrical connection
In order to ensure an economical and reliable installation that complies with
the limits of temperature and voltage drop, it is necessary to determine
maximum load of appliances connected to the installation. In determining the
maximum load for an installation or for a part of it, it is required to take into
account contemporaneous factors. For supply systems, the following must be
determined:
- Power system (AC/DC) - Data regarding voltage and absorbed power/
current is given on the rating plate.
- Ground protection: Grounding the appliance will prevent the user from
getting exposed to electrical shock in case of electrical insulation
damage.
- The installation must always be secured with a minimum 10 A fuse.
- If you have more than one unit, each unit must be connected to an
individual fuse group.
If the connection is a 3-pole connection, use a three-pin plug and connect the
conductor with yellow / green insulation to ground. In order to maintain a
stable operation of the unit, voltage variation cannot dier more than ±10
percent of the nominal voltage supply. Always follow local regulations when
preparing an installation. Contact your local authorities if in any doubt.
!
Only qualified/authorized engineers or service personnel should
install the unit. Installation by unqualified personnel may cause elec-
tric shock or fire.
Always make sure the unit is grounded to protect the user from
electrical shock.
Do not use the power supply cord if it is damagaged. Such supply
cord may cause fire or electric shock.
Never use a telephone line or lightning rod as ground protection.
During lightening, there is a strong current present, which is
extremely dangerous.
Do not use water pipes as ground protection. Modern water pipe
systems are non-conductors such as PVC.

11
Replacing the power cord may only be done by authorized personal.
!
Never use gas lines as the ground protection for the unit. This can
cause an explosion.
Disconnect the power cord if there is something wrong with the
unit. Continued abnormal operation may cause electric shock or
fire.
Getting started

procedures shall be followed.
1. Plug the power socket in a dedicated outlet. For correct voltage
requirement, follow the information on the rating plate. When started,
let the appliance cool for minimum 2 hours before placing any products
in it. During transport it is probable that the compressor oil has entered
the cooling system blocking the capillary. As a consequence, the
appliance will function for a certain period of time, though without
cooling, until the oil has returned to the compressor.
2. When the appliance initially starts up, the buzzer alarm may sound.
This is normal. You can push the buzzer alarm button to cancel the
sound.
3. This appliance has been factory set to operate at +5°C (refrigerator) or
- 20°C (freezer).
