CM5A/CM5B COILS
KMABA BLOWERS
For Manufactured Homes
4THE CM5A/CM5B INDOOR COIL
To complete your cooling or heating system, the model CM5A
or CM5B Coil is installed inside your Evcon/Coleman, Nor-
dyne/Miller/Intertherm or AirPro gas or electric downflow fur-
nace. Both coils are uncased, and designed for installation
within the manufactured home furnace casing or inside a fac-
tory-installed plenum. These indoor coils are designed to be
used in conjunction with blower kits and other accessories.
The CM5A and CM5B coils are designed for quick and easy in-
stallation by a qualified service technician.
The CM5A comes with factory-installed mechanical connec-
tions. The CM5B comes with factory-installed sweat connec-
tions. Both coils utilize a Check-Flo-Rater® piston for refrig-
erant flow control. Both coils can be used in cooling-only
applications or as part of a heat pump system.
When heating in conjunction with a heat pump, the outdoor
heat pump unit recovers heat from the outdoor air, and trans-
mits it to the CM5A or the CM5B indoor coil for distribution to
the living space.The CM5A and CM5B coils are not activated
when heating in conjunction with a furnace without a heat
pump in the system.
Built-in drainage assembly ensures leak-free condensate re-
moval. Periodic cleaning of filter and drainage sections is rec-
ommended to avoid possible sediment blockage.The A-shape
design of the coil provides maximum cooling-heating transfer
surface and ease of handling at installation.Four coil sizes are
available from 024 though 048, covering a wide range of cool-
ing-heating capacities to meet varying manufactured home re-
quirements.
THE KMABA BLOWER
KMABA Blower Kits and Accessories are designed and built to
meet the needs of the manufactured housing market.The kits
are used to upgrade Nordyne and Evcon gas and electric fur-
naces (see note). For cooling and heat pump duty, kits avail-
able include blowers for up to 4 tons of air conditioning, control
boxes, insulation kits, filter kits, and evaporator coil shelves.
Blower kits for gas furnaces are shipped without controls.Order
the control box from accessory usage chart.Blower kits for elec-
tric furnaces are shipped with or without controls. See acces-
sory usage chart for details. All control box kits are designed to
operate with a minimum 4-wire thermostat.
Quick connect wire harnesses are shipped with the appro-
priate blower kit or control box for ease of installation. Sheet
metal adapter plates also are included with the blower kits that
are needed to adapt the blower with the furnace.
NOTE: Intertherm, Miller, Coleman, and AirPro brands.
