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.

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.

WARNING

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.

This heater is not intended for use in exposed outdoor,

marine, or wash-down environments or in areas where

corrosive liquids or fumes exist under normal conditions.

ELECTRIC SHOCK HAZARD. Any installation involving

electric heaters must be performed by a qualiﬁed person

and must be effectivley grounded in accordance with the

National Electrical Code to eliminate shock hazard.

Do not mount mercury type thermostat directly on unit. Vibration

could cause heater to malfunction.

The heater must be mounted at least 7’ above the ﬂoor to prevent

accidental contact with the heating elements or fan blade which could

cause injury.

Keep at least 5’ clearance in front of the heater. Refer to Table D

for side, top and back clearance requirements.

warning (cont’d.) Table B – Weights of Heater & Bracket The ceiling mounting structure and the anchoring provisions must be of sufficient strength to support the combined weight of the heater and mounting bracket. (Refer to Table B for weights of heater and bracket.) The wall or mounting surface, and the anchoring provisions must be capable of supporting the combined weight of the heater and mounting brackets cantilevered from the mounting surface.

Wiring REMOTE SUMMER FAN SWITCH (MANUAL SWITCH-LINE VOLTAGE). The wall switch is packed in the wiring compartment. The remote fan switch is mounted external and remote from the HVH unit heater. The voltage of the remote fan switch is the same as the supply voltage to the HVH heater. 1. Use 14 gauge copper, NEC Class 1, 600V rated insulated wire. Wiring must meet all Local and NEC requirements for 480-volt service. 2.
