DESCRIPTION

This unique modular system allows the flexibility to handle an y
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 requirement.

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 a ppli­cation. 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, prov iding 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" fo il face
insulation to prevent sweating.

Thermal Expansion Valves - Coils are ordered as “Flex-coil”
unit without a factory installed mertering device. Flex-coil mod­els allow for field installed R-22 or R-410A TXV’s for added flex­ibility to meet refrigerant system choice.

Electric Heaters - Both single and three phase electri c heater
models are available to match any requirement. All heaters
include nickel-chromium elements with a 5-year limited war­ranty on 1 Ø heating elements and 1 yea r li mi ted w arranty o n 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 fro m ai rfl o w lo ss w it h fu si bl e li nk
backup protection.

Communication - These models may be connected as part of
a communciations system using a 4-wire connection bus.

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:

AIR HANDLER VOLTAGE

208/230-1-60 187 - 253

* Rated in accordance with ARI Standard 110, utilization range “A”.
Air flow must be within the minimum and maximum limits approved for electric

heat, evaporator coils and outdoor units.

1. Airflow at nominal voltage, bottom return at 0.5 external sta tic pressure, tested without filter installed, dry coil conditions.

2. These units have variable speed motors that automatically adjust to provide constant CFM from 0.0” to 0.6” w.c. static pressure.

3. From 0.6” to 1.0” static pressure, CFM is reduced by 2% per 0.1” increase in static.

4. Operation on duct systems with greater than 1.0” w.c. external static pressure is not recommended.

5. Both the COOL and the ADJUST tap must be set to obtain the cooling airflow desired (CFM).

6. The ADJ tap does not affect the HEAT tap setting.

7. Low speed cooling used only with two stage outdoor units. (Speed is preset to 65% of high speed).

8. Dehumidification speed is 85% of jumper selected COOL tap and ADJUST tap.

9. When operating in both heat pump and electric heat modes, the airflow (CFM) will be per HEAT Tap CFM values only.

10. At some settings, LOW COOL and/or LOW HEAT airflow may be lower than what is required to operate an airflow switch on certain models of electronic air
cleaners. Consult the instructions for the electronic air cleaner for further details.

11. Airflow (CFM) indicator light (LED2) flashes once for every 100 CFM (i.e.: 12 Flashes is 1200 CFM) – blinks are approximate +/- 10% of actual CFM.
