Chromalox HVH-02-81 Installation, Operation And Maintenance Manual

Type HVH Horizontal/Vertical Unit Heater
Heater Location Instructions:
Arrange units so their discharge air streams:
A. Are subjected to a minimum of interference from columns,
machinery and partitions.
B. Wipe exposed walls without blowing directly at them.
C. Are directed away from room occupants in comfort heating.
D. Are directed along the windward side when installed in a build-
ing exposed to a prevailing wind.
E. See additional mounting limitations in Table D.
Locate thermostat on interior partition walls or posts away from
cold drafts, internal heat sources and away from heater discharge air
streams.
Small rooms can be heated by one unit heater. Where two walls
are exposed, the heater should be mounted as shown in Figure 1.
Failure to understand and follow these installation instructions and
the "WARNING" notes therein may result in serious personal injury
from electrical shock, or from the heater falling due to faulty installation.
This heater is not intended for use in hazardous atmo-
spheres where flammable vapors, gases, liquids or other
combustible atmospheres are present as defined in the
National Electric Code. Failure to comply can result in
explosion or fire. For these applications see PDS CXH-A-
EP (PF490).
ELECTRIC SHOCK HAZARD. Disconnect all power before
installing or servicing heater. Failure to do so could re-
sult in personal injury or property damage. Heater must
be installed or serviced by a qualified person in accor-
dance with the National Electrical Code, NFPA 70.

Large rooms require multi-unit installation. Number and capacity
of units will be determined by volume of building and square feet of
floor area to be heated. Arrange units to provide perimeter air circula-
tion where each unit supports the air stream from another.
