Install Instructions

Installation
Heat exchanger with a refrigerant distribution system should
be mounted with the distributor at the bottom.

For an evaporator, the pipe should be straight (at least 150 mm
/ 5.9 inch length) be tween the expansion valve a nd refrigerant
inlet. Avoid using pipe e lbows between the expansion valve
and the re frigerant inlet.
The heat exchan ge
r could be of single or dual circuit type.
Flow direction of a single circuit heat exchanger is normally
parallel, while on dual circuit heat e xchanger could be diagonal
or parallel. M ak
e sure that the heat exchanger is ins talled
correctly according to the current flow direction for the heat
exchanger. For detailed information about flow direction see
the name plat
e.
Connections can be placed in the front or rear of the heat
exchanger. Typical installation of a dual circuit heat exchanger
as an evaporator:

Water/Brine inlet and outlet are typically positioned on the
rear side.
Leak test
Perform leakage test before placing the plate heat exchanger
in operation.
