Prior to installation we recommend that the installer verify the product intended application is
applicable to your current installation needs. The system application for this model combination is dual
heat, gas or oil furnace as standby, outdoor heat pump unit, and the heat pump manufacturer's room
thermostat. If your application does not include dual heat with standby furnace, but electric heat with an
air handler, do not use this WarmFlo II series or this installation manual. Contact factory for other
models (EM-WE series, WF-DH*** kits, etc.).
EM-WU***** – WarmFlo Electro-Mate ranging from 10 kW to 25 kW. Can be installed in upflow
applications only.
EM-WD***** – WarmFlo Electro-Mate ranging from 10 kW to 25 kW. Can be installed in downflow
and horizontal applications.
Caution, Heat Pump Application: Depending upon mechanical positioning and airflow, in all
cases (heat pump) the electric element, Electro-Mate, unit must be on the supply or warm side of
the HP refrigerant coil.
First-time or non-routine user – before attempting installation or setup, suggest studying the last section
of this manual, operational information and terminology definitions. Attached HD320 is also a training
document. Also if you have not attended a WarmFlo training session, call the factory for other
descriptive documents or PowerPoint.

in place and functional. This controller is designed to operate the complete heating system - heat pump,
backup furnace (gas or oil), Electro-Mate, room thermostat, WF outdoor sensor, etc. If one of these
components is missing or not initially installed, improper performance of WarmFlo II and the system may
be experienced. In other words, if the gas furnace doesn't exist, LP tank not yet installed or filled, and the
WarmFlo II is operating on a cold day; do not be disappointed if there is no heat.
