4. Without A-coil, install Electro-Mate as high as
possible but maintain side takeoff position related to
the elements.
5. The Electro-Mate "V" must be installed parallel to
"A" frame of the coil and as close as possible to the
A-coil top.
6. Any plenum larger than 19” width or 20” depth
requires deflectors, see figures C-1 and C-2.
7. Shown is 20 kW model. 10 & 15 kW models have the
element stack 1.5" lower, thus the 3" can be
considered 1" min (25 kW, 5").
8. WarmFlo supply sensor (ST) is installed 12" above
Electro-Mate enclosure, directly above elements.
Notes:
1. If horizontal distribution is
not equal, increase to 14".
2. Electro-Mate hole opening -
8" x 15" or 8" x 18".
3. Plenum size - if larger baffling required, see
figure C-1 or C-2.
3" MIN.
