NOMENCLATURE
ACCESSORIES-FIELD INSTALLED (CONT.)
HOT WATER COILS
These drainable coils have 2 rows of 1/2" copper tubes, 12
aluminum fins per inch, a casing that is finished to match the
exterior of the basic unit, but no water control valve. The coils
slide out of their casings for easy field installation. They
should be mounted over the return air opening on 7-1/2 and
10-ton units—between the unit coil and blower sections on 15
and 20 Ton units.
STEAM COILS
These non-freeze coils have 1 row of 1" copper tubes, a 5/8"
copper tube inside each 1" tube to distribute the steam evenly
across the entire length of the coil, 8 aluminum fins per inch,
a casing that is finished to match the exterior of the basic unit,
but no steam control valve. The coils slide out of their casings
for easy field installation and are pitched in their casings to
facilitate condensate drainage. They should be mounted over
the return air opening on 7-1/2 and 10-ton units—between
the unit coil and blower sections on 15 and 20 Ton units.
SUSPENSION KIT
Suspension kit 1HH0451 is available for 15 and 20 Ton units
installed horizontally. The accessory includes channel iron
supports and the hardware to secure them to the top of the
unit. Hanger rods must be field furnished.

tem and fan switches are available to control the operation of
these split system air conditioners.

Two drive packages are available to provide a blower RPM
range that meets almost any air delivery requirement. Vari-
able pitch motor pulleys can be adjusted to provide the
