The WCM/WM coil is a High Capacity Hydronic Water Coil
available as an add-on module to the Hi-Velocity System.
Mainly used in the chilled water applications for cooling, this
coil can also be used for heating with water temperatures up to
130°F (54°C).
When the potential for gravity flow of the hot water exists,
check valves may be needed on both the supply and return lines.
All lines should be piped so as not to restrict access to the front
panels, filter section, or electrical enclosure. Size your supply and
return lines according to Table WCM-01.
Piping the WCM/WM
The coil comes as a module and must be installed in the
vertical position on the return air side of the fan coil. The WCM/
WM come supplied with two L mounting brackets for connection
to the fan coil (Fig. WCM-01). When mounting the cooling coil,
ensure that no screws puncture the drain pan or coil.
The WCM comes complete with 2 built-in 3/4” (19mm) drain
lines, primary and secondary. Ensure the primary drain line is
vented and P-trapped.
The use of a mixture of gylcol will reduce capacities; refer to
gylcol manufacture reduction charts.
