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:
