6.  Empty the fryer and rinse thoroughly with water.  

Use a 1 part vinegar to 15 parts water solution to 
rinse the tank and neutralise any cleaner 
residue.  Use a weaker solution of up to 1 part to 
25 water if this proves unsuitable for the cleaner 
being used. 

7.  Rinse the tank thoroughly with water, drain and 

dry. 

8.  Refill the tank with new filtered frying medium. 

 
Stainless Steel Surfaces 

a.  With the tank(s) drained, cleaned and dried 

as shown above, clean the exterior of the 
fryer with hot water, a mild detergent solution 
and a soft cloth.  Note that the gas control 
knobs can be removed to allow cleaning of 
the front control panel. 

b.  Dry all components thoroughly with a dry 

cloth and polish with a soft dry cloth. 

c.  To remove any discolouration, use an  

approved stainless steel cleaner or stainless 
steel wool.  Always rub in the direction of the 
grain. 

 

Periodic Maintenance 

NOTE: 
All maintenance operations should only be carried 
out by a qualified service person. 
 
To achieve the best results cleaning must be regular 
and thorough and all controls and mechanical 
parts should be checked and adjusted periodically 
by a qualified service person.  If any small faults 
occur, have them attended to promptly.  Don't wait 

until they cause a complete breakdown.  It is 
recommended that the appliance is serviced every 
6 months.

5.  Use a drain stick, to stir up any solid medium into 

the top medium to melt it. 

6.  Slip a muslin or other suitable bag over the drain 

valve.  Crumbs will be caught in the bag but 
frying medium will strain freely through bag into 
the receptacle. 

7.  When the tank is empty, use a small tank with a 

handle as a ladle and dip into the hot frying 
medium from receptacle and pour vigorously 
around sides and bottom of the tank to wash 
out crumbs and particles adhering to them.  
Continue to dip and pour until all crumbs are 
washed down and into the filter bag. 

8.  Open drain valve fully, check for any particles or 

crumb residue lodged in the valve.  Clean out 
with a stiff nylon brush.  Do not use wire brush or 

metal rods as these damage the seating in the 
valve and will cause valve leakage. 

9.  If the obstruction in the valve cannot be 

removed with a brush, use a wooden probe. 

10. Clean the control panel with a damp cloth 

lightly moistened with a solution of mild  
detergent and water.  Wipe dry with a clean dry 
cloth. 

11. Once the daily cleaning operation is  

completed, close the valve and pour the frying 
medium back into the tank and continue the 
days work.  Straining takes less time than frying 

one load of potatoes and will pay dividends in 
food quality and saving of frying medium. 

 

Weekly Cleaning 

NOTE: 
If the fryer usage is very high, we recommend that 
the weekly cleaning procedure is carried out on a 
more frequent basis. 

 

1.  Proceed as for “Daily Cleaning” to drain and 

filter the tank.  Do not refill the tank with frying 
medium until it has been cleaned as shown 
below. 

2.  Fill the fryer with cold water to the normal fill level 

and add a high quality commercial cleaner that 
has been specifically formulated for fryers.  All 
purpose cleaners are not recommended

 

NOTE: 
Never use a caustic or lye solution, as this will leave 
a fat destroying film on the tank. 

 

3.  Heat the water to approximately 80-90°C. 
4.  Clean the fryer baskets by simply immersing 

them in the cleaning solution.  Allow fryer to soak 
for 5-10 minutes or as directed on the cleaner 
instructions.  Remove the baskets and turn OFF 
the main burners. 

5.  Scrub the baskets and fryer tank lightly, but 

vigorously with a stiff nylon bristle brush to 

remove any remaining deposits.  DO NOT use a 
wire brush, as this will scratch the sides
