PRODUCT DESIGN

The MBR/MBE blower cabinets with proper coil matches can

be positioned for upflow, counterflow, horizontal right or

horizontal left operation. All units are constructed with R-4.2

insulation. In areas of extreme humidity (greater than 80%

consistently), insulate the exterior of the blower with insula-

tion having a vapor barrier equivalent to ductwork insulation,

providing local codes permit.

The CAPX/CHPX coils are equipped with a thermostatic

expansion valve that has a built-in internal check valve for

refrigerant metering. The CACF/CAPF/CHPF coils are

equipped with a fixed restrictor orifice.

The coils are designed for upflow, counterflow or horizontal

application, using two-speed direct drive motors on the

CACF/CAPF/CHPX models and BPM (Brushless Perma-

nent Magnet) or ECM motors on the MBE models.

The ARUF is a multi-position air handler (upflow/horizontal

or downflow) and is equipped with a flowrator for cooling and

heat pump applications. Because of its seamless copper

tubing and aluminum fins, there are fewer leaks. The steel

cabinet of the ARUF is fully insulated and rust resistant.

Thermal expansion kits for air conditioning and heat pump

applications are available.

ARPF*B 2 to 5 ton air handlers are dedicated for downflow

operation and are approved for modular homes. Flowrater.

transformer and blower time delay are on all standard ARPF

units. Both the ARUF and ARPF have direct-drive multi-

speed motors.

AEPF is a multi-position, variable-speed air handler and can

be used with R-410A or R-22 (models ending in 1/16). The

unit's blower design includes a variable-speed DC motor and

is compatible with heat pumps and variable-capacity cooling

applications.

ASPF is a multi-position air handler that can be used with R-

410A or R-22 and it features a X-13 motor. This motor is a

constant torque motor with very low power consumption and

it is energized by a 24V signal. The X-13 features an

integrated control module and is compatible with heat pumps

and cooling applications.
