  • Page 28: Pump Controller Wiring Notes

    Non-Nortec valve controllers can be used with the HP HVAC system. In these cases the valve controller is wired to the pump controller, as it would be with a Nortec valve controller. The valve controller need only close the loop, and does not need to provide a voltage or current. If the valve controller does provide a signal, it should be wired to a relay which will then close the pump controller loop.

    Mist Eliminator Maintenance 1 The HP HVAC system should typically be installed downstream of air filters to minimize Mist Eliminator maintenance. In any case, Nortec recommends an annual inspection of mist eliminator media. 2 If the media is becoming contaminated with dust, it should be removed and cleaned with a vacuum or gentle water spray.
