THERMOSTATS 
A thermostat will not heat the water. A thermostat is an electrically con- 
trolled automatic switch that will turn the aquarium heater on or off at 
whatever temperature it is set for, thus maintaining a constant water teim- 
perature. These thermostats we have listed are all precision instruments, 
laboratory tested, accurate within two degrees. All thermostats are guaran- 
teed by the manufacturer. 
PLEASE REMEMBER 
A heater and thermostat is a precision instrument—and an elec: 
trical appliance. Treat it as such—use it, do not abuse it—and it wil! 
give you years ot trouble free service. We list here a few '"DONT'S” 
which if observed will prolong the life of your heating equipment. 
DON’T—Allow water to get into tube of heater or thermostat. 
DON‘’T—Remove heater from aquarium without first disconnecting ii 
from the electric—allow it to cool off before removing or replacing. 
DON‘T—Put heater or thermostat in water if glass tube is cracked. 
If it is necessary to remove heater to clean aquarium, inspect the 
tube carefully for breakage. 
DON’T—Connect thermostat units until metal thermal unit has ad- 
justed itself to the water temperature. If moisture forms inside the 
tube from condensation, dry thoroughly before connecting.
