Product overview
The AGA R7 allows the user to operate the cooker as a traditional heat storage AGA, with the ovens
on all the time whilst the hotplates can be turned on or off:
•The Boiling plate 340°c (644°F) and the Simmer plate 240° (464°F) are controlled by
mechanical thermostats to reach their target temperatures
•The Roast Oven has a temperature of approximately 230°C (446°F)
•The Baking Oven has a temperature of approximately 175°C (347°F)
•The Slow Cook Oven has a temperature of approximately 115°C (239°F )
•The AGA R7 also comes with a low energy setting
•The Boiling and simmer plate are controlled by mechanical liquid filled thermostats with
overheat protection on the neutral side.
•The ovens are controlled by a PCB and a thermocouple with overheat protection on the
neutral side.
Full information regarding the operation of the Aga R7 is located in the user guide.
General information
Regular servicing is not required for this cooker
DO NOT ALTER or MODIFY the appliance.
The appliance warranty does not cover commercial use.
Please refer to the Aga R7 cooker installation instructions for specific information regarding
appliance dimensions, clearances, electrical requirements and oven venting etc.
Installation instructions and are available to view at www.agaliving.com/
*Important Note*
Before carrying out work on the appliance, the power supply MUST be isolated and tested for safe
electrical isolation.
The main cooker assembly is electrically tested before leaving the factory.
Always inspect the cooker before any work is carried out and notify the customer of any existing
damage.
The cooker has 5 cooking zones: boiling plate, simmer plate, roast oven, baking oven and simmer
oven.
The boiling and simmer plate use the same 2.5kw circular element and the ovens utilise a 1.75kw
element which is accessible by removing a plate in the roof of the baking oven.

Cooking zones
Below is a picture showing the different cooking zones on the Aga R7. The hotplates are
independently controllable using the control knobs located behind the top left hand control door.
In the USA / Canada the simmering oven is called the slow cook oven.
Aga R7 150
The Aga R7 150 has a hotcupboard attached to the parent Aga, the hotcupboard is supplied
either with a warming plate or a single zone induction hob on the top. In the USA/ Canada the
slow cook oven is called the simmering oven.

The User Control Panel
The Aga R7 has been designed so that it is simple to use. There is one control dial to operate the hot
plates, and one control dial to operate the Roasting, Baking and Simmering Ovens and on the 5 oven
R7 150 model there is one button to operate the hot cupboard.
Like the classic Aga cooker design the Aga R7 has a Boiling plate and a Simmer plate. Each hotplate is
individually temperature controlled.
Each of the three ovens have their own pre-set temperature settings.
The customers control panel is located behind the top left hand door, we recommend engineers
familiarise themselves with the users instructions on the operational modes of the cooker so they
understand how the cooker works.

Page 6of 26
The User control panel symbols for the ovens.
Normal – for everyday use, maintains the ovens at a temperature suitable for roasting,
baking and simmering in the respective ovens. 446 degrees F ( 230 degrees C )
Low – for reduced temperature cooking (50ºF lower than normal). To achieve the lower
cooking temperature from normal, allow 2½ hours before intended use. To return to
normal cooking temperature from this mode allow approximately 2 hours before
intended use.
High – for higher temperature cooking (50ºF higher than normal). To achieve the higher
cooking temperature from normal, allow 2 hours before intended use. To return to
normal cooking temperature from this mode allow approximately 2½ hours before
intended use.
Slumber – Slumber mode on the R7 allows the cooker to retain warmth in the appliance
at reduced energy giving best economy. To achieve normal cooking temperature from
this mode allow approximately 3½ hours before intended use.
Oven temperature indication
For each mode the respective icon will flash while warming up, once the desired
temperature is reached the respective icon will be illuminated ‘solid’ red. The icon
remains ‘solid’ and does not flash when cooling down between modes.

Power supply connections.
The Aga R7 range must be supplied with a 240v, 60Hz power supply and connected to an individual
properly grounded branch circuit protected by a circuit breaker, at 240volts it has a maximum load
of 30amps .Electric hook up must be done by a licensed electrician .The unit must be installed
according to regional codes, or in the absence of codes, the National Electrical Code.
Product installation requires a separate (not shared) 240V/40 amp circuit protected by an
appropriate branch circuit supply.
The service cord on your range is fitted with a standard four (4) prong type 14-50P plug (matching
receptacle 14-50R).
The method of connection to the mains electricity supply must facilitate complete electrical isolation
of the appliance.

Essential tools
Always protect the cooker and work area before carrying out any work on the appliance, and always
inspect the cooker for any existing damage before starting work.
When undertaking maintenance work on this appliance, the engineer should ensure the following
tools are available
•Multi meter
•Clamp meter
•Insulation resistance tester
•Tool kit
•Torque driver with screwdriver bits
•Torque setting chart
•Hob support bars - (AE4M280399)
The electrical connections on the Aga R7 must be tightened by the use of a torque screwdriver,
please see the table on the next page for the relevant settings.

How the hotplates and ovens work
Behind the top left hand door sits a small control knob which simultaneously operates either the
Boiling plate, Simmering plate or both. In each of the hotplates there is powerful heating elements.
The Hotspot and Simmer spot elements are similar to the units used on the AGA eR7, but now
consist of three internal single circuit elements rated at 2100W , 200W , 200W giving a factory
selectable wattage of 2500W or 2300W.
The boiling spot uses all 3 elements - 2100w + 200w + 200w.
The simmer spot uses only 2 elements - 2100w + 200w.
The Boiling plate reaches its target temperature in approximately 11 minutes from cold, while the
simmering plate will achieve its target temperature in around 8 minutes.
With the Simmer spot selected, power is applied permanently to the 200W element, the Simmer
spot thermostat and also the 2100W element in the Simmer spot.
As the spot temperature rises to the set temperature, the 2100W element switches off and the
continuously operating 200W element maintains the simmer spot temperature.
When the plate lid is opened and a cooking pan placed on the spot, the plate cools, the simmer spot
thermostat will call for heat and switch in the 2100W element. The thermostat will then cycle to
maintain the simmer temperatures with the lid open.
Manually resettable thermal cut-outs are fitted to prevent any overheat conditions. (Sited behind
the glass control panel)
The hotspot functions in the same way as the Simmer spot but the maintenance wattage is 400W
and the hotspot temperature is higher.

How the Ovens work
The ovens are standard radiant heat ovens the heat source is a 1.75kw element, they work
like a standard heat store Aga, and they can also be set to a low energy setting, which will
reduce all of the oven temperatures of the AGA R7 cooker.
Full temperature can be reached in just a few hours from the low energy setting, while
providing a comforting ‘warm to the touch’ feel. From this low energy setting, time must be
allowed for the ovens to reach their target full heat setting again. The low energy setting is
not recommended for cooking.
Typical element resistances.
Oven element 1.75kw (1500watts) 30 Ohms,
Boiling plate 2.5kw (2100w +200w+200w =2500watts) 21 Ohms,
If testing the 2 x 400watt circuits for the above this will be approx 132 Ohms.
Simmer plate 2.3kw (2100w + 200w = 2300watts) 23 Ohms
If testing the 200 watt element for the above this will be approx 264 Ohms
