DESCRIPTION

This unique modular system allows the flexibility to handle any
application. These versatile coils and blowers may be used for
upflow, downflow, or horizontal left or right applications. They
may be combined to function as a cooling only unit or with a heat
pump including electric heat for 1 and 3 phase applications. The
blower and electric heater could be used as stand alone electric
furnaces.

FEATURES

BLOWERS - Models to match any air flow or voltage require-
ment. The compact size allows easy installation. Blowers are
sized to deliver design air quantity both efficiently and quietly.
The motors provide a selection of air quantities to match any
application. All models include a one-minute blower off delay as
standard to enhance system efficiency ratings. The durable, pre-
painted steel protects the unit against rust and corrosion. All
models have 1 inch foil face fiber glass insulation, providing a
thermal insulation value of R-4.2. 

COILS - Staggered rows of rifled copper tubes are mechanically
expanded into enhanced surface aluminum fins to provide high
heat transfer and long-lasting quality. The MC multi-position
coils may be used for upflow, downflow, and horizontal left or
right applications. Coil cabinets are insulated with 3/4" foil face
insulation to prevent sweating.

ELECTRIC HEATERS - Both single and three phase electric
heater models are available to match any requirement. All heat-
ers include nickel-chromium elements with a 5-year limited war-
ranty on 1 Ø heating elements and 1 year limited warranty on 3
Ø heating elements. Sequential operation is provided to control
heaters in all models. Circuit breakers are used in 208/230 volt,
single-phase heaters of 15 KW and larger.

Models equipped with circuit breakers may be altered in the field 
to use multi-source power supply. Over-temperature limit 
switches provide protection from airflow loss with fusible link 
backup protection.

ACCESSORIES - A full line of matching accessories available
for use with the blower and coils to allow any type application.

LIMITATIONS - These units must be wired and installed in 
accordance with all national and local safety codes.

Voltage limits are as follows:
