Part No.21966 Rev. M February 2016 - 8 - Heated Well GN Series
OPERATION
Configuration
DROP-IN HEATED WELL ASSEMBLIES - OPERATION
Mechanical
Features
The drop-in well consists of a main assembly, in which
gastronorm dishes of various sizes can be mounted.
A separate control panel is pre-connected to the well
assembly, by a two metre cable.
Operational
Modes
This versatile heated well can be operated in various modes, and with various
dish depths:
Wet well with 65 mm dishes
Wet well with 100 mm dishes
Wet well with 150 mm dishes
Steam well with assorted dish sizes
Dry well with assorted dish sizes
Operating
Temperature
The operating temperature of the well is adjustable, using the digital controller.
There are optimum temperature settings for each of the modes of operation.
Overflow and
Drain
A combined water overflow
and drain is provided.
Ideally this should be
connected to an external
drain. Otherwise a suitable
receptacle must be used.
Larger models are fitted with two drains.
Auto-fill
Auto-fill options are available for all cabinet sizes, see Mechanical Drawings.
A valve, connected to the water level sense unit, a flow control valve and a
sediment trap are plumbed to the mains water supply.
Optional
Lighting
An optional lighting gantry is available. The well assembly has provision for
mounting the gantry and is pre-wired for the heat lamps and water level
indicator.

IN-GNH03/4/5/6/8 - 9 - © Future Products Group
Controls
DROP-IN HEATED WELL ASSEMBLIES - OPERATION
Control Panel
A control panel, mounted on the joinery, provides for all
operational adjustments.
Temperature
Main On/Off Switch
Operating Mode
Indicator lights are also provided to show when the water level is
low and when the heating elements are on.
Temperature
The display normally shows the actual well
temperature.
To adjust the operating temperature, first press and
hold the left hand button for two seconds. Whilst
still pressing it, use the up or down arrow button to change the temperature
setting. Release both buttons to store the new temperature setting.
The display will now revert to showing the actual well temperature.
Operating
Mode
Rotate the mode switch to the appropriate position for the
required dish depth and type of operation.
65mm –100mm –150mm –Steam –Dry
On/Off Switch
Rotate this switch to turn the heating on and off.
If an overhead lighting/heating gantry is fitted, it is controlled
by a switch on the support post.
Indicator
Lamps
The water level is monitored, according to the setting of the
mode switch, the lamp coming on if the level is too low.
Detector probes, positioned in the side of the well, ensure the
correct water level for three dish sizes and steam mode.
A second indicator lamp shows when the heating elements are operating.

Part No.21966 Rev. M February 2016 - 10 - Heated Well GN Series
Operating Mode
DROP-IN HEATED WELL ASSEMBLIES - OPERATION
Choice of Mode
It is important to select an appropriate operating mode, to suit the type of food,
the type of dish and the required food temperature.
The actual food temperature can be influenced by many variables, and it is
important to regularly check actual food temperatures with a thermometer.
Dry Mode
In this mode, no water is
used. The air in the well is
heated by the elements, and
the dishes are warmed by
conduction and radiation
through the air.
The capacity of air to conduct
heat to the dishes is low, and
uniform heating is difficult to
achieve. The radiant heat from the elements can cause hot spots, particularly if
deep dishes are used.
This mode works best if the food in the dishes has a high liquid content, to allow
heat circulation inside the dish.
Steam Mode
In this mode, the heating
elements are covered with
water, but the dishes do not
touch the water.
Heat is transferred to the
dishes by the steam. The higher thermal capacity of the water vapour/steam
ensures faster heat transfer and more even dish temperatures than with a dry
well.
Dishes of differing depth can be used, but 150 mm dishes will tend to wet mode.
Wet Mode
In this mode the water level is
higher, so that the dishes are
in contact with the water.
This gives the highest heat
transfer rate to the dishes, and
a uniform temperature is more
easily achieved.
For correct operation, the
dishes should be of equal
depth. Settings are provided
for three sizes, 65 mm, 100
mm and 150 mm deep.

IN-GNH03/4/5/6/8 - 11 - © Future Products Group
Temperature Settings
DROP-IN HEATED WELL ASSEMBLIES - OPERATION
Setting Guide
The following temperature settings for the operating modes are a guide only.
Actual food temperatures should be regularly monitored, to ensure appropriate
storage conditions.
The required settings will depend on ambient conditions, whether overhead heat
lamps are used and whether the dishes have lids etc.
Dry Mode
Temperature
The suggested temperature setting for dry mode operation is 110°C.
Steam Mode
Temperature
The suggested temperature setting for steam mode operation is 95°C.
Wet Mode
Temperature
The suggested temperature setting for wet mode operation is 75°C.
Storage and Display Basics
DROP-IN HEATED WELL ASSEMBLIES - OPERATION
Food
Temperature
In general, hot food should be kept at 65°C or above.
The heated-well MUST have reached its working temperature, before food is
loaded.
Food MUST be pre-heated to the required temperature, before it is placed in the
display dishes. Alternatively a whole filled display dish can be pre-heated, and
exchanged for a dish in the heated-well.
Display Time
The permissible display time will depend on the ambient conditions and food
type. Use of an overhead heat/lighting gantry will increase display times.
Items such as fries, wedges and burgers could typically be displayed for 20
minutes.
Times can be greatly increased if lids are used.
Unsuitable
Food Type
Larger joints of meat are best kept in a closed heated cabinet, to prevent drying
out.

Part No.21966 Rev. M February 2016 - 12 - Heated Well GN Series
Preparation
DROP-IN HEATED WELL ASSEMBLIES - OPERATION
Power Supply
Ensure that power is connected to the cabinet.
Decide on the
Required Mode
If wet or steam operation is to be used, first add water to cover the elements.
The correct water level for the various modes is shown on the depth gauge, on
the inside of the well.
Turn the mode selector to the appropriate setting, to start heating up the well.
The level indicator lamp should be off and the element indicator on.
Caution
Turn on Lights
If fitted
It is important to turn on the overhead heat lamps, whenever steam is escaping
from the heated well, whilst pre-heating and during normal operation.
If this is not done, condensation will cause premature lamp failure.
Pre-heat the
Well
Set the temperature controller to the required setting and allow the well to reach
the required operating temperature, with dishes in place, before adding food.
The well temperature is indicated on the controller display, and the Element On
indicator lamp will extinguish when the set temperature is reached.
To reduce the pre-heating time, the well can be filled with hot water.
NOTE Setting the controller to a higher temperature than required will not
speed up the heating process. Set it to the desired temperature.
Fumes and
Odours
Before first use, operate the cabinet for 4 hours to remove any fumes or odours,
which may be present. This will avoid possible tainting of food.
Load Food
Load with pre-heated food products.
When correctly set, the temperature of pre-heated products will be held above
65C.
This is not an oven, so do NOT place cold products in the dishes.
Monitor
Temperatures
It is important to regularly monitor the temperatures of the food in the dishes.
Trim the electronic controller setting, as necessary, to obtain the required
temperature.
Monitor Water
Level
Monitor the water level indicator lamp, and if the lamp comes on, add more
water to restore the correct level for the chosen operating mode.

INSTALLATION
Regulations
DROP-IN HEATED WELL ASSEMBLIES - INSTALLATION
Compliance
with Local
Requirements
It is very important that your drop-in heated well assembly is installed correctly
and that the operation is correct before use. Installation must comply with local
electrical, health & safety and hygiene requirements.
Setting Up
DROP-IN HEATED WELL ASSEMBLIES - INSTALLATION
Unpacking
Unpack and check unit for damage and report any damage to the carrier and
supplier. Report any deficiencies to your supplier.
The well is supplied fully assembled, with the control panel connected to the
main assembly by a two metre cable.
Food dishes and supports may be packed separately.
Site
Preparation
Ensure the well location and any bench cut outs are made to the precise
measurements shown in the Mechanical Drawings. Position the well in its
allocated working position. Use a spirit level to ensure the well is level from side
to side and front to back. (If this is not carried out, uneven temperature
distribution could occur).
Well Assembly
Preparation
Remove all tapes, ties and packers, used to prevent movement during transit.
Lift out the food dishes, grills and divider bars.
Check that all plastic film protection has been removed from surfaces; otherwise
it will melt when the well heats up.
Grounding
WARNING: THIS APPLIANCE MUST BE GROUNDED TO EARTH

Setting Up cont.
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.
Location
DROP-IN HEATED WELL ASSEMBLIES - 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.

Part No.21966 Rev. M February 2016 - 18 - Heated Well GN Series
SERVICING
Control Gear
DROP-IN HEATED WELL ASSEMBLIES - SERVICING
Location
The incoming mains cable is terminated on a
connecting block in an enclosure on the side of the
