Non-Mixing ProMelt available in both 150 and 250 MBH sizes.
Heat Exchanger ProMelt available in 399 MBH.
An integrated hydraulic separator ensures proper flow
through both the heat source and zone. Each ProMelt
system includes either a 670 or 680 tekmar snow melt
control and corresponding snow/ice sensor.
All panels come pre-wired, including the circulators,
actuators, and disconnects. A standard 120 VAC
receptacle plug is pre-wired to the panel to simplify
wiring. Make sure a 120 VAC receptacle is located within
three (3) feet of the ProMelt panel.
Before unpacking the ProMelt panel(s), check the
package for damage. Make sure there are no seriously
crushed edges on the cover or surrounding supports. If
damage is evident, report this to the shipping company.
Contact Watts Radiant for assistance, if needed.
Note if the shock indicator sticker has been discolored.
If the indicator has turned red, the ProMelt panel has
experienced excessive shock and should be reported to
the freight carrier.
Any type of damage can
result in improper opera-
tion, both mechanically and
electrically. Do not attempt
to fix damaged areas without
obtaining written instructions
from Watts Radiant on how
the corrections are to be
performed.
