LCH036 through 074
LCH036H, 048H, and 060H are high efficiency packaged
units equipped with direct drive blowers. LCH036S, 048S
and 060S are standard efficiency packaged units equipped
with two speed belt drive blowers. LCH072H, 074H are high
efficiency packaged units equipped with a single and two
speed belt drive motors.
Optional electric heat is factory or field installed . Electric
heat operates in single stage depending on the kW input
size. 7.5kW through 30 kW heat sections are available for
the LCH unit.
Information contained in this manual is intended for use by

pressure.
3 Using total air volume and system static pressure requirements determine from blower performance tables rpm and motor output required. Maximum usable output of
motors furnished are shown. In Canada, nominal motor output is also maximum usable motor output. If motors of comparable output are used, be sure to keep within the
service factor limitations outlined on the motor nameplate.
