HEATERS
When installing a heater on the pool, a 1" PIPE OR GATE VALVE BY-PASS TO PARTIALLY DIRECT WATER AROUND THE
HEATER IS NECESSARY. This allows part of the water through the heater for heating but limits the head loss created when
all the water is directed through the heater. THE IN-FLOOR SYSTEM MAY NOT FUNCTION PROPERLY WITHOUT THIS
BY-PASS.
NOTE: MULTI-SPEED PUMPS AND HEATERS
& HEAT PUMP
When plumbed with a bypass the heater or heat pump may
not fire with pump running on the lowest speed.
