NORDIC® “DX” Series Typical Plumbing & Ductwork
NOTE:
If (2) valves are installed on the hot water lines as
shown in this diagram then a pressure relief valve
(set at 75 - 100 psig.) must also be installed to pre-
vent the build-up of pressure which may result in
bursting of the circulator pump housing if the unit
is operated while both valves are shut.
(See point “A” marked above)
Nordic® DX (All Models)
•
Hot water lines are 1/2” ID copper.
