INSTALLATION

4)MOUNTING THE HUMIDIFIER

MODEL EHU-701:Making sure the unit is level, hold it against the mounting surface and mark the hole pattern. Attach the units to studs or other sturdy structure with the two 3/8"× 1½" lag screws provided.

MODELS EHU-703 & 704: Making sure the mounting bracket is level, attach it to studs or other sturdy structure with the two 3/8"× 1½" lag screws provided. Hang the humidifier on the mounting bracket.

5)ELECTRICAL SERVICE WIRING

Refer to the nameplate on the unit for recommended fuse size. Table 6-1 relates the fuse size to the appropriate branch size. A complete wiring diagram shown in Figure 12-1 is located inside the door of the humidifier.

IMPORTANT: Please observe the following:

a.Make certain there is a manually operated interlocking circuit breaker or safety switch (not furnished) in the electric service ACCESSIBLE TO AND WITHIN SIGHT OF THE HUMIDIFIER.

b.USE ONLY WIRE WITH COPPER CONDUCTORS RATED 90°C OR HIGHER FOR HIGH VOLTAGE AND GROUNDING.

c.Pass high voltage ground lead through provided ferrite core (AN) between where it enters the cabinet and where it connects to ground lug.

d.Ground the humidifier cabinet; a ground lug is provided in the wiring compartment.
