Section 2. General Information
IMPORTANT - Follow all National and local codes when
installing this hydronic coil.
This accessory hydronic coil is designed to deliver primary or
secondary heating capacity and can be used in either a po-
table or non-potable water system. Maximum entering water
temperature is 180 °F.
1. Check the hydronic coil nameplate to confirm that the se-
lected hydronic coil is approved for use with the air handler.
2. Check the components received for damage. Report any
defects or shortages to the transportation company im-
mediately.
NOTE - Since the hydronic coil mounts over the discharge
end of the air handler, it is necessary that the equipment
power enter from one of the side conduit entry points.
