The following section outlines pump sizing for domestic hot water
recirculation and tank loading. Only models approved for such
applications are listed in this section.
• Size the pump according to the pressure drop curve of your
Infiniti® K model (fig. 1 below) and the loop pressure drop
tables.
• Maximum flow allowed for tank loading through the pump
loop is 5 GPM.
• Must be 0.45 gpm to activate unit
• DHW recirc loop pump must circulate enough gpm to
account for normal loop heat loss and to ensure that the
recirc pump eventually satisfies and turns o
4.2 PUMP SIZING FOR CIRCULATION
For direct DHW recirculation and tank loading
applications: Run the system for 30 minutes to remove
debris from the plumbing. Then remove the unit‘s inlet
water filter to decrease pressure drop through the
system. If the inlet water filter, when removed, contains
debris, it is recommended to install a 40 mesh Y-strainer
(installer supplied) on the cold water inlet.
