MECHANICAL INSTALLATION
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.
Depending upon application, refer to the appropriate drawing and Electro-Mate position.
 EA104, revision E and above – heat pump – below A-coil.
 EA111 – air conditioning, non-heat pump – above A-coil.
ADDITIONAL HEAT PUMP COMMENTS: Since this is probably associated with a heat pump, these
instructions and drawing EA104 assume a A-coil where the air is driven backwards through the A-coil. If
your installation is a slant coil or a V-coil, positioning of the Electro-Mate is still the same, in the case of
the V-coil you can have a much tighter installation.
The 1” minimum spacing of the actual Electro-Mate front enclosure and the bottom of the drip pan is a
compromise because typically vertical space is at a premium. If you can allow additional space under the
drip pan, do so.
For this type of installation where the air is coming out of the center hole in the drip pan, actually the use
of a 15” wide Electro-Mate is preferred. This would be opposite the normal recommendation for a 15”
wide unit in large plenums. However, there still should be side and end baffling even though the air is
coming out of the drip pan center. In this situation there will definitely be turbulence and unpredictable
flow as it comes out of the center hole. Make sure all the air is forced through the Electro-Mate elements.
FURNACE TYPE - This unit must be installed in as DOWNFLOW application only. Do not turn the
Electro-Mate upside down or install this unit in the cold air return.
Verify that all transitions have angles less then 3Ø°, the Electro-Mate is centered within the plenum, and
there are no odd shaped angles or odd shaped transitions within the plenum.
If the width or depth is greater than approximately 1” of the Electro-Mate element pattern, side and back
deflectors may be required. Use the same general deflector requirements and techniques normally
described in the Electro-Mate upflow manual. If you are not familiar with this, request drawing EH1Ø8.
For horizontal applications reference manual HI320.
If the DOWNFLOW furnace is setting directly on the floor, the furnace will have to be raised for
insertion of the Electro-Mate unit. This will require a field designed and constructed plenum. This
plenum must have sufficient strength to carry the weight of the existing furnace.
