ELECTRICAL INSTALLATION
Power and control wiring is to be routed into the humidifier through the pipe chase in the base pan of the outdoor models located in the burner area.
Installation details for primary and low voltage control wiring are the same as for indoor units.
A field supplied NEMA rated weatherproof disconnect switch must be mounted external to the GS Outdoor unit to allow for power interruption during servicing and/or maintenance. A mounting plate, located on the front of each outdoor model above the electrical access door, is available for mounting of the disconnect switch. Two electrical conduits are provided for routing the primary wiring to the disconnect switch and then back inside the enclosure to the main power terminal strip. See Figure #20 for details.
