Model EDH–4 Rev E Installation and Operation Manual
Mounting
Install this unit in compliance with National Electrical Code (NEC) and Canadian Electrical Code (CEC)
standards, as well as all other local and applicable electrical codes for your area. Prior to beginning installa-
tion, make sure that the facility has properly sized electric service and breaker. For additional information re-
garding electrical ratings and facility power requirements, refer to the Specifications section of this manual.
The EDH–4 mounting brackets will accommodate fasteners up to 1/4 inch (6.3 mm) in diameter. The
choice of anchors and companion hardware should be appropriate for the mounting surface. At least four
anchors should be used and each should be capable of supporting a combined load of at least 5 pounds (2.4
kg). The locations of the mounting points are shown in Figure 3A, Narrow, and Figure 3B, Wide.

For wall mount installation, rather than attaching the mounting
brackets at the holes along the 4.81" (122.2mm) edge (Figure 4A), align
and attach them to the holes along the 7" (177.8mm) edge (4B). Pro-
ceeding clockwise, the unit is reoriented with the mounting brackets
against its mounting surface (4C), the front display panel (with handles)
swapping positions (4D) with “eTi” front cover (4E).
The surface used for the installation should be capable of supporting
four times the weight of the unit, or about 32 pounds (14.5 kg). Be sure
to install the unit directly to a solid, stable surface. Mount the unit to the
wall (or other vertical surface) before con-
necting any other components to it.
