GENERAL The hot water coils can be drained and have two rows of 1/2" copper tubes. They also have twelve aluminum fins per inch, a casing finished to match the exterior of the basic unit, but no water control valve. The coils can slide out of their casings for easy field installation over the return air opening of the Figure 2 units, and between the coil and the blower sections of the Figure 3 units. All of the steam coils are the steam distributing type. They have one row of 1" copper tubes, each containing a 5/8" copper tube to distribute the steam evenly along its length. The coils have eight aluminum fins per inch, a casing that is finished to match the exterior of the basic unit, but no steam valve. The coils can slide out of their casings for easy field installation and are pitched in their casings to facilitate condensate drainage.

Position the heating coil in (or on) the unit as shown.
CAUTION 1.
Since hot water and steam coil accessories for Figure 2 units will be located before the unit filters, a field-supplied filter rack will be required.
2.
Hot water coils may NOT be used for steam under any circumstances.
3.
Steam coils have a “two way” pitch for both vertical and horizontal applications. The condensate connections must be positioned at the lowest point.
4.
Steam pressure must be limited to 25 psig. If available steam pressure is greater than 25 psig, a pressure regulating valve must be installed and set for this maximum pressure.
2.
Remove the end panels.
3.
Remove and discard all shipping angles and/or screws and packing so coil is free to move within the casing.
4.
Install the four nut retainers, position support angles and secure the sections together with screws as indicated.
5.
Replace the end panels.
REMOVING COIL 1.
Disconnect the piping.
2.
The heating coil may be removed from either side of the coil casing. Remove only the end panel and support angles on the side from which the coil is to be removed.
INSTALLATION 1.
Refer to Table 1 and Figures 2 or 3 and select the appropriate illustration. •
Figure 2 is for horizontal and vertical units with the heating coil installed on the return air opening.
•
Figure 3 is for horizontal and vertical units with the heating coil installed between the evaporator and blower sections.
Installer should pay particular attention to the words: NOTE, CAUTION and WARNING. Notes are intended to clarify or make the installation easier. Cautions are given to prevent equipment damage. Warnings are given to alert installer that personal injury and/or equipment damage may result if installation procedure is not handled properly.
