Hydronic Coil Installation

Reference Figure I-IP-3 and follow the procedure below to install the hydronic coil.

1.Remove the front grill, filters, two upper frame screws, and two lower frame screws.

2.Install the hydronic coil in the space previously occupied by the grill.

3.Use the frame screws and one of the grill screws to clamp the coil end supports between the unit frame and the mounting brackets (supplied with the coil).

4.Slide the filters in the filter rack from either end of the coil.

5.Adjust the filter rack for 2-inch filters by

removing the upper and lower filter support brackets.

6.The hydronic coil can be installed for either right or left-hand connections. However, steam coils must have the condensate lines connected to the bottom outlet, with the top outlet capped.

7.A heating coil control relay is factory provided to use with BAY28X182 and BAY28X183 thermostats. Drill two 5/32” holes 7/16” apart and mount the relay in the unit control box as shown in the detail drawing below. Use a 6-32X.31 screw (not included) to mount the relay. Connect wiring in accordance with the thermostat wiring diagram.
