Williams WBC30 User Manual

The electrical installation and connections should
meet the necessary requirements to the local
electrical wiring regulations and any electrical safety
guidelines and use the following:
• Copper conductors only, for mains supply wiring
• Use conductors with a minimum cross-sectional
area (CSA) of 12AWG (4.00mm
2
)
• Suitable overcurrent protective device (fuse/
circuit breaker) with a 10kA or greater breaking
capacity
*WARNING! Risk of electric shock.
Some conductors remain live when
the equipment is in standby.
Safely isolate from the power
supply before servicing.
* Applicable to the U.S.A cabinets only.
All appliances rely upon a suitable connection to
earth to ensure safe operation. If in doubt, contact
a qualied, skilled and competent electrician before
using the appliance.
The equipment must be connected to the correct
mains power supply as stipulated by the appliance
data label and local authority regulations.
We recommend:-
• Supplementary electrical protection with
the use of a residual current device (RCD)
• Fixed wiring appliances incorporate a
switch disconnector for purposes of
safe isolation to meet their specication
requirements of IEC 60947
WBC/WBCF10 & 20 are single phase and come
tted with a moulded plug for safety and must be
earthed. We recommend that should the plug
or cable fail contact Williams Spares Oce for a
replacement part.
WBC/WBCF30 & 40 are single phase. They should
be connected to a 16A single phase supply by a
qualied refrigeration engineer or electrician.
WBC/WBCF50, WBC70 & WTBC70 are 3 phase.
They should be connected to a 16A 3 phase and
neutral power supply. This should be carried out by
a qualied refrigeration engineer or electrician.
WBC40 RN should be connected to a 16A 3 phase
(no neutral) by a qualied refrigeration engineer or
electrician.
If the appliance has been laid on its back
or tipped, DO NOT switch on immediately.
Leave in an upright position for at least 3
hours before switching on.
CONNECTION TO A MAIN DRAIN
All models (except WBC/WBCF50, WBC70,
WBC40RN & WTBC70) feature automatic
evaporation so no drain is required.
WBC/WBCF50, WBC70, WBC40RN & WTBC70
requires the condensate drain pipe to be connected
to a suitable 19mm waste pipe or larger ‘P’ trap or
routing to an open oor drain. (This can be found at
the base of the cabinet rear).
ADJUSTABLE TROLLEY GUIDES (WTBC70)
The WTBC70 comes with 1 set of adjustable trolley
guides.
Depending on the required trolley these should
be tted either to the inside (Lainox) or outside
(Rational) set of holes on the underside of the
cabinet.
