To complete your cooling or heating system, the model CM5A
or CM5B Coil is installed inside your Evcon/Coleman, Nordyne/Miller/Intertherm or AirPro gas or electr ic downflow furnace. Both coils are uncased, and designed for installation
within the manufactured home furnace casing or inside a factory-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 installation by a qualified service technician.
The CM5A comes with factory-installed mechanical connections. The CM5B comes with factory-installed sweat connections. Both coils utilize a Check-Flo-Rater® piston for refrigerant 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 transmits 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 removal. Periodic cleaning of filter and drainage sections is recommended to avoid possible sediment b loc kage . The A-shape
design of the coil provides maximum cooling-heating transfer
surface and ease of handling at installation. F our coil siz es are
available from 024 though 048, covering a wide range of cooling-heating capacities to meet varying manufactured home requirements.
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 furnaces (see note). For cooling and heat pump duty, kits available include blowers f or 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 electric furnaces are shipped with or without controls. See accessory 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 appropriate 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.
