INSTALLATION
ELECTRICAL INSTALLATION
Commercial kitchens and foodservice areas
are environments where electrical appliances
and equipment may be located close to liquids,
or operate in and around damp conditions, or
where restricted movement for installation and
service is evident; therefore Williams Refrigeration
recommend that this equipment be protected by an
appropriately selected RCD with a rating no greater
than 30 mA.
If the equipment is required to be fixed wired, a
switch disconnector / isolator to the specification
of IEC 60947 should be installed in the fixed wiring
of the installation to provide a suitable all pole
disconnection of the power supply.
Only qualified, skilled and competent persons (i.e.
an electrician) are to carry out required electrical
installation work. The equipment must be installed
in accordance with local wiring Regulations;
safe systems of work must be adhered to at all
times during the installation process. Refer to
the equipment dataplate and wiring diagram
for confirmation of the electrical power supply
requirements.
This equipment must be correctly earthed.
Supplementary protective equipotential bonding
of the equipment may also be necessary, and if
it is required, a skilled, qualified and competent
electrician should install this to in accordance to
local wiring Regulations.
On completion of the electrical installation, electrical
safety tests (such as earth continuity and insulation
resistance) must be carried our and documented by
a qualified, skilled and competent electrician prior
to powering up the equipment for commissioning
purposes.
REMOTE CONDENSING UNIT
If a remote condensing unit is required it must be
installed in accordance with local wiring Regulations;
safe systems of work must be adhered to at all times
during the installation process.
An appropriately selected RCD with a rating no
greater than 30 mA is recommended to protect
the remote condensing unit as the refrigeration
system pipework is common with the refrigeration
equipment.
A switch disconnector / isolator to the specification
if IEC 60947 should be installed in the fixed wiring
of the installation to provide a suitable all pole
disconnection of the power supply.
The equipment must be correctly earthed.
Supplementary protective equipotential bonding
of the equipment may also be necessary, and if
it is required, a skilled, qualified and competent
electrician should install this to in accordance to
local wiring Regulations.
Refer to the manufacturer's technical specification
information when determining the electrical supply
requirement for the condensing unit.
GENERAL INSTALLATION
Installers should ensure they are appropriately
trained and competent in understanding
general safety risks associated to undertaking
the installation. These include assessing and
recognising risk such as;
•
Use of correct (electrical) tools
•
PPE
•
Working at height;
- Ladders
- Scaffold and edge protection
•
Lone working
•
Permit to work requirements
•
Manual handling;
- Safe lifting and load bearing storage and
positioning of units
•
Caution to outside locations and weather
conditions;
- High wind, rain and snow and direct
sunlight
- Risks associated to animal and vermin
intrusion
REMOVAL OF REDUNDANT APPLIANCES
Refrigeration appliances contain refrigerant and
gases in their insulation and must be disposed of
professionally by a licensed waste management
contractor.
Please ensure that old or redundant refrigeration
appliances are disposed of safely and legally.
