  • Page 31: Heating

    Electric heaters are available in a number of different sizes and each heater has a control module that modulates the output of the heater. The heater control module is controlled by an analog signal from the controller. See illustration below. See the RenewAire Electric Heat Module User Manual for further information.

  • Page 32: Cooling

    There are primarily three different methods for accomplishing hot gas reheat. All three include a condenser reheat coil but require different equipment and are connected and piped differently, based on the method. Consult your RenewAire sales representative or the factory for further information and for help in specifying an HGRH coil.

  • Page 57: Drain Trap Construction

    Drain trap design is dependent on the static pressure at the drain location and also whether the pressure is negative or positive. For all drain traps, RenewAire recommends the installation of threaded plugs at several locations to permit periodic cleaning and filling of the trap. Also recommended is the use of a vacuum breaker if water is being discharged from the trap into a drain pipe.

  • Page 58: Waterless Drain Traps

    5.7.4 Waterless Drain Traps Accessory As an alternative to a field-fabricated and installed condensate P-trap, RenewAire offers an HVAC waterless trap as an accessory. The advantages to a waterless trap are that they may require less vertical clearance for (negative pressure) installations, they generally do not require winterization and they do not require priming at the beginning of the cooling season.
