Commissioning must include a functional check of all controls and a calibration
check on the thermostat. Oil temperature should be checked once the main burners
have cut out for a second time.
Upon handover, ensure all operators know how to safely light, operate and
shutdown the appliance and are aware of the isolating cock.
Supply Pressures
The appliance is connected directly to the gas supply where the gas supply pressure
is controlled at the source of inlet in the building or via the governor attached to the
bottle gases. See Technical Data for the supply pressures.
Connection is at the rear of the unit via a 1/2" G male thread. If connection to the
supply pipe is via a flexible hose, ensure that the hose used is suitable for
commercial catering appliances.
Undo the screw and attach a pressure gauge to the boss of the test nipple which is
located on the gas inlet pipe.
Light the oven burner and set thermostat to the highest setting and check the
pressure. The hose shall be periodically examined and replaced as necessary.
For Propane with a 50mbar supply pressure a governor is required for
adjustment to 37mbar.
Connection shall comply with local regulations.
When making the connection to the appliance, secure the hexagon on the fitting to
prevent rotation of the internal pipe work. An isolating cock should be fitted into the
supply line
close to the unit, for

After setting refit regulator cap and tighten test point screws (Fig 2, A, B, C)
NOTE: appliances operating on Butane gas there may be some ‘yellowing’ of the
flame at the burner –this is normal owning to the composition of the gas.
OPERATION INSTRUCTIONS
This appliance is for professional use and must be operated by qualified or trained
personnel only.
This unit is intended to be used to produce deep fried products only.
Note: The recommended frying weight is 750g (0.75kg) per basket.
Operator precautions
Do not leave the appliance unsupervised whilst operating.
Never put water in the oil and always drain food of excess moisture before frying.
Avoid overloading the baskets with product.
Do not use dust cover lid whilst operating.
Always allow oil or fat to cool before replenishing –do not attempt to add cold oil to
hot whilst cooking.
Notes on frying
Good quality vegetable oil is recommended, which has a higher smoke and fire
temperature than animal fat, and also carries less taint when different products are
fried in the same oil.
The life expectancy of oil will lengthen with regular filtering, and will also be extended
if the appliance is turned to standby when the fryer is not in use.
Old oil becomes more prone to boil or surge. It also has a lower flashpoint and will
be prone to overheating. Changing oil frequently reduces the risk of a fire hazard.
It is advisable to defrost frozen food first –cooking from frozen will affect the heating
recovery time, lowering output.
Always allow the oil to heat to temperature before introducing product.
Preparation for use
Ensure the drain valves are closed.

IS676 ECN4560

Fill the tanks with water and a little mild detergent to the lower indicated mark on the
batter plate. Do not use flammable solvents and cleaning aids.
Following the Lighting Instructions, turn the appliance on and allow the water to boil
for a short time.
Switch off and drain the water.
Rinse the tank and dry thoroughly.
Run a small quantity of oil across the base of the tank and allow it to drain. This will
remove any residual water and provide the tank base with a coating of oil.
Close the drain valve, fit the blanking nut and fill the appliance with clean oil to the
lower level, maintain oil at the upper level during service.
