E.ELECTRICAL INSTALLATION

(1)Only qualified personnel should install electrical wiring. All wiring must be in accordance with national and local codes.

(2)Power and control wiring is to be routed into the humidifier through the pipe chase in the base of the unit.

(3)A field supplied NEMA rated weatherproof disconnect switch must be mounted external to the NH Outdoor unit to allow for power interruption during servicing and/or maintenance. A mounting plate, located on the side of each outdoor model, is available for mounting of the disconnect switch. Two electrical cutouts are provided for routing the primary wiring from the disconnect switch to the main power terminal strip inside the unit.

(4)Installation details for primary and low voltage control wiring are the same as for indoor units.

F.WATER SUPPLY LINE

(1)The water supply line is critical to the proper operation of the humidifier. Humidifiers primarily operate in the cold winter months when freezing is a serious issue. To prevent freezing of the humidifier, a water supply line freeze protection system should be ordered and used in conjunction with a normally open / normally closed valve arrangement described below. NORTEC’s limited warranty does NOT cover damage resulting from freezing.

(2)There are two alternative configurations for the supply line plumbing. The first method involves using a normally open / normally close valve arrangement (see Figure 5). The valves should be installed inside of the building to prevent freezing. The water should flow from the supply through a normally closed valve. This valve should always be closed unless energized by the humidifier. This prevents water from flowing to the humidifier when there is no demand, or in the event of a power failure. After the first valve the water should flow to a tee. The central branch of the tee is to be plumbed to the humidifier. The remaining branch of the tee should is to be connected to a normally open valve. This valve remains open to allow water to drain back from the outdoor lines when there is no demand from the humidifier or in the event of a power failure. When energized by the humidifier, this valve will close and allow water to flow to the humidifier. With this configuration the outdoor line will be empty unless the humidifier requests water. This effectively eliminates the chance of water freezing in the outdoor portion of the line.

(3)The second method operates on the same principle as the first, however it replaces the two-valve configuration with a single safety three-way water valve. This valve is to be installed inside of the building. When the humidifier begins to operate, it will energize this valve and send water to the humidifier. When the humidifier is not in use, the valve will close the supply, and allow water in the outdoor lines to flow to drain. See Figure 6 for details.

(4)The valves described above should operate on either a 24V or 110V signal and should be wired to the appropriate terminals inside of the humidifier.
