DIRECTIONS FOR FITTING UP INCUBATORS HEATED BY GAS. 



Fill water jacket with warm water a few degrees less than temperature required. 



Connect gas supply to coupling B of regulator by metal composition pipe or indiarubber 

 tube. This gas supply pipe should be provided with a tap. Turn on gas supply and light burner 

 under Incubator. 



When the required temperature is reached the gas will be lowered by the expansion of the 

 capsule c. If gas is not lowered when the temperature required is indicated on thermometer turn 

 the disc D to the left until flame is just lowered. Should the flame be lowered by the expansion 

 of capsule before the required temperature is reached turn disc D to the right. 



The byepass screw F should now be adjusted so that the gas flame is further lowered until 

 it is only about f in. high. 



If it is required to remove the capsule c, open doors of Incubator and push capsule towards 

 side of Incubator until the small stud is clear of plate-holder G, then slide out plate-holder G, 

 when capsule will drop out. 



Complete Instructions are attached to each Incubator.
