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  
TECHNICAL GUIDE  
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.  
MODELS: MV  
MODULAR VARIABLE SPEED AIR HANDLERS  
FOR USE WITH SPLIT SYSTEM  
COOLING & HEAT PUMP  
1200 - 2000 CFM BLOWERS  
3 - 5 TON COILS  
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.  
OPTIONAL 1 & 3φ ELECTRIC HEATERS  
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:  
NORMAL OPERATING  
AIR HANDLER VOLTAGE  
VOLTAGE RANGE*  
208/230-1-60

Filter Rack - One of the following external filter rack accesso-  
ries: 1FR07* or 1FR08* must be used when unit is installed  
for application outlined.  
ACCESSORIES  
Refer to Price Manual for specific model numbers.  
Electric Heaters - Models shown under Electrical Data  
include sequencers and temperature limit switches and fus-  
ible links for safe, efficient operation. Circuit breakers are pro-  
vided where shown.  
Combustible Floor Base - If an electric heat accessory  
which is rated for greater than zero clearance to combustible  
surfaces is installed in these air handlers in the downflow  
operating positions on a combustible floor, one of the follow-  
ing combustible floor base accessories is required: 1FB1817,  
1FB1821, or 1FB1824.  
Suspension Kit - Suspension Kit Model 1BH0601 is  
designed specifically for upflow application of the units con-  
tained in this technical guide. For suspension of these units in  
horizontal applications, it is recommended to use angle sup-  
port brackets with threaded rods at locations shown in air  
handler installation instructions.

All CFM’s are shown at 0.5” w.c. external static pressure.These units have variable speed motors that automatically adjust to provide constant CFM from 0.0” to  
0.6” w.c. static pressure. From 0.6” to 1.0” static pressure, CFM is reduced by 2% per 0.1” increase in static. Operation on duct systems with greater than 1.0” w.c.  
external static pressure is not recommended.  
NOTE: 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.  
* The ADJ “D” tap should not be used.

All CFM’s are shown at 0.5” w.c. external static pressure.These units have variable speed motors that automatically adjust to provide constant CFM from 0.0” to  
0.6” w.c. static pressure. From 0.6” to 1.0” static pressure, CFM is reduced by 2% per 0.1” increase in static. Operation on duct systems with greater than 1.0” w.c.  
external static pressure is not recommended.  
NOTE: 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.  
* The ADJ “D” tap should not be used.
