INSTALLATION DO’S
Do
flush out all supply and return water lines between the unit and the water heater after
installation and before start-up to eliminate flux, metal chips, sand, or any other
particulate matter just as you would with any other plumbing systems.
Do
use only non-lead solder and flux agents.
Do
remember to install a properly designed mixing valve to the domestic service should
the water heater be set as to deliver water at a temperature greater than 120 °F.
*SPECIAL NOTE*
SOME JURISDICTIONS
may require a backflow preventer in the incoming cold water
line to the water heater. In such cases the Temperature and Pressure Valve of the water
heater may weep OR relieve due to expansion of the water when heated. Note that this
would occur even if this air handler were not installed. A small diaphragm-type thermal
expansion tank will normally eliminate the weeping condition. Please read and follow
the manufacturer’s instruction for installation of such tanks.
Further Note : The above DO’S and DON’TS apply to air heaters which are
installed with water heaters in a hydro-air application.
However, our air handlers can be installed on closed loop boiler systems as well. When
doing so, make sure you follow all locally approved codes and installation practices.
In keeping with our policy on continuous product improvement, we reserve the right to
make changes without prior notice.
