OPERATING INSTRUCTIONS FOR COOLER 

 

It is important to read through these instructions carefully before operating the cooler. 
 
This instruction manual should be kept in a safe place for future reference.

USER OPERATING INSTRUCTIONS 
 
Note: Appliance cannot be run off 2 heat sources at the same time. 
 
TO START GAS OPERATION 

 
1.  Open the shut-off valve for the gas bottle (check that there is enough gas). 
 

Open any shut-off valve of the gas installation. 

 
2.  Open flap B. 
 
3.  Keep the flame failure device knob (A) pressed in for approximately 15 seconds. 
 
4.  Release for 10 seconds, strike match and insert into flap hole.  Press (A) again. 
 
5.  Keep the knob (A) pressed in for a further 15 seconds then release it.  If the flame 
 

goes out, repeat steps 2, 3 and 4 until the flame stays alight. 

 
To terminate the gas operation turn off the shut-off valve on the gas bottle. 
 
On starting the cooler, it will take a few hours to start becoming cold. 

 

  Once  the  burner  (B)  has  been  lit  turn  the  gas  thermostat  (C)  to  position  ‘7’  for 

maximum cooling (clockwise).

 

  By  adjusting  the  thermostat  (C)  knob  down  from  position  ‘7’  you  can  regulate  the 

temperature you desire in the bottle cooler.

 

 

NOTE:

  The gas safety valve knob (A) should never be depressed for periods longer than  

15 seconds with the burner unlit, as this can cause a potentially dangerous build-
up  of  unburnt  gas.  If  the  burner  does  not  ignite,  allow  sufficient  time  for  any 
unburnt gas to disperse, then repeat the ignition steps.
