GENERAL SAFETY

The “Eemax three Module, Single Phase” heater is specifically designed to take in cold water 
and heat it to temperatures suitable for normal domestic usage up to a maximum of 140 F(60 
C). To obtain optimum performance and energy savings, the unit should be located as
near as possible to the point of use. “Thermostatic” models indicated by the letters “T2T or 
T3” after the model number, these models and only these, can be fed with pre-heated water 
and be used to boost temperature

The unit is supplied with 3/4” NPT pipe connections.  Under no circumstances use a blow 

torch on pipe which is connected to the heater (serious damage to the electronic flow 

switch will result). Carefully use Teflon  tape, ensuring no debris enter the heater.  

Do not

use pipe dope.

Also, ensure that the pipes are clear of installation debris before fitting the heater.
