3 Steps to Choosing
your Atmor Unit
STEP 1:
Define your point of use application(s)
in the sizing chart (right).
For example: Single Sink, Double Sink,
Single Shower, Sink and Shower.
STEP 2:
Locate your geographical region on the above
map of the United States to identify the inlet
cold water temperature for your region.
The correlating color coding for your region
will be necessary for Step 3.
STEP 3:
Finally, reference the sizing guide chart
to locate your point of use application,
then cross-reference to find the color code
associated with your region’s inlet cold
water temperature. Within that column,
you will see which unit best fits
your application.
Temperature Rise
Reference Guide
Controlling the flow rate (Gallons per Minute) into your unit is essential to ensure a proper consistent temperature rise in order to
meet your desired hot water temperature. When experiencing a high flow rate, it is recommended to use a flow restrictor or aerator
at your application to achieve optimal temperature rise. See below for further information.
