DROP-IN HEATED WELL ASSEMBLIES - INSTALLATION
Power Supply Before connecting to the power supply, check that the local supply is correct to
that shown on the rating plate, located on the side of the well.
To assist with load balancing, the heating elements are star-connected ,
enabling the well to be connected to a three phase + neutral supply , or the
phase terminals can be bridged, to use a single phase supply.
Isolation A mains switch is fitted on the well assembly, next to the control gear panel.
If the well is hard wired to the mains supply, an external means of isolation must
be provided.
If a plug and socket are used, they must be accessible after the well is installed.
Protection For reasons of safety for personnel, it is strongly recommended to fit a Residual
Current Device, (RCD), in the mains supply to the well.
An over-temperature cut-out is fitted on the well. This will interrupt the mains
supply to the elements, if the well overheats for any reason.
Water Supply
Adjust the flow control valve, to achieve an appropriate fill rate on auto-fill units.
In areas where the water supply has a high mineral content, the water for the
well should be conditioned to prevent deposits forming on the inside of the well
and building up on the heating elements.
In severe cases, thick mineral layers could build up on the elements. This could
result in element failure, if the well is later run in dry mode.

INSTALLATION
Ventilation
The well is designed to meet the HACCP specifications with free room air
circulation.
The well should not be placed in a location where draughts could cool the
displayed food, i.e. close to a door or air conditioning vent.
Access
Access to the underside of the well is required for draining the water and
servicing.
Fumes and
Odours Before use, add water to the well and operate the cabinet for 4 hours at 90°C, to
remove any fumes or odours, which may be present. This will avoid possible
tainting of food.
