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
selected hydronic coil is approved for use with the air

2. Check the components received for damage. Report any
defects or shortages to the transportation company im-

end of the air handler, it is necessary that the equipment
power enter from one of the side conduit entry points.
