First Co SHW (2 - 20 Tons) Horizontal Chilled Water - Manual

The SHW blower coil units are
designed to be installed in a horizon-
tal position with discharge air in a
horizontal direction. The SVW
blower coil units are designed for
installation in a vertical position with
discharge air in a vertical direction.
Both unit models incorporate a posi-
tive slope drain pan with a 3/4" NPT
nipple that exits the unit on the side
of the coil header connections. All
units need to be leveled in such a
way to insure positive slope toward
the condensate drain nipple.
NOTICE: Before mounting unit
remove red headed shipping
bolts and metal bushing at
blower base and blower outlet. In
addition remove, if present, the
wire tie securing motor to blower
rail before operating.
Sufficient clearance must be pro-
vided on the side of the blower coil to
allow access to electrical controls
and to service the motor blower as-
sembly.
Standard unit configuration is right
hand looking with the direction of
airflow. The unit can be field con-
verted to left hand by repositioning
the coil, drain pan and remounting
the motor and pulleys.
NOTE: Motor rotation must be re-
versed. See motor nameplate for
details.
