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 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. 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.
