Braze Plate (BPHE) Chiller
Evaporator water inlet and outlet types, sizes and
locations are shown in drawings in Dimensions and
Weights chapter. Installation of a field provided 1/2” x
14 NPTE stainless steel or PVC plug is required.
Strainer
Install a strainer in the water supply line to protect the
chiller from plugging with system piping debris.
Strainers should be installed as close as practical to the
heat exchanger water inlet (the remote chiller
accessory kit includes strainer and piping to connect
with BPHE). A field provided blow down valve
(recommended) or plug must be installed in strainer
cleanout if not present.
