WARNING
GENERAL
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
atmospheres where flammable vapors, gases, liq-
uids 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 result in personal injury or property dam-
age. Heater must be installed or serviced by a qual-
ified person in accordance with the National
Electrical Code, NFPA 70.
ELECTRIC SHOCK HAZARD. Any installation involv-
ing electric heaters must be performed by a quali-
fied 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 pre-
vent accidental contact with the heating elements or fan blade
which could cause injury.

out through the louvers, interchange any two of the three customer
power leads on three-phase units only.
Table B – Weights of Heater & Bracket
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
building exposed to a prevailing wind.
Locate thermostat on interior partition walls or posts away
from cold drafts, internal heat sources and away from heater dis-
charge 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.

WIRING
ELECTRIC SHOCK HAZARD. Be sure electricity is
turned off at main switch first before wiring. Any
installation involving electric heaters must be
effectively grounded in accordance with the
National Electrical Code to eliminate shock hazard.
1. Use heater only on the voltage and frequency specified on the
nameplate.
2. All wiring should be done in accordance with local codes and
the National Electrical Code by a qualified person as defined in
the NEC.
3. Two knockouts are provided on the back of the heater for wire
entry. See Figure 4 for location of knockouts.
4.
Branch circuit wire for connection to heater must be at least
60˚C wire.
5. The bottom access door is hinged. There are two screws that
must be removed to gain access (Figure 3).
6.
A ground wire is provided near the power connection point.
The ground wire should be connected before other connec-
tions are made
.
7. Terminals on contactor or on line voltage terminal block are
supplied to be connected to accept the correct size power sup-
ply wire. Copper rated at 600V and 60˚C is satisfactory for the
heater branch circuit.
8. Electrical accessories, either kits or factory-installed options, are
shown connected by a dash line on the heater wiring diagram.
9. Wiring connections are to be made on designated wire leads as
shown in the wiring diagrams located inside the access door.
10. Louver adjustment (Do not attempt to adjust while heater is
operational): Louvers have been preset at factory with the
minimum open angle. Decreasing the 45˚ angle may result in
high temperatures and functioning of the over temperature con-
trol. To increase the opening angle, grasp the left end of louver
with the left hand using the index finger and thumb. Grasp right
end of louver with right hand in the same manner. Twist louver
to the desired position.
POWER DISCONNECT SWITCH
(Available as a kit or factory installed option). This switch dis-
connects the power to the power leads when the handle is turned to
its off position. Refer to Instruction Sheet PF207.
1. Use copper conductor supply wire only when connecting to the
power line. (See Figure 8.)
2. Connection to the switch pigtails should be made with com-
pression connectors and the joint should be then well insulated.
3. Consult the local wiring code in your area.
SUMMER FAN SWITCH - Refer to Instruction sheet PF205
without relay, PF206 with relay.
(MOUNTED ON FRONT OF HEATER). When the switch
handle is pointing toward the SUMMER (FAN ON) position, the
fan will run continuously. When the switch handle is pointing
toward the WINTER (HEAT) position, the fan will run only when
the heating elements are hot.
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 volt-
age 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.
Install the remote fan switch in standard wall box in any conve-
nient location that is protected from traffic or other accidental
damage.
3. Connect the 14 gauge copper field wire to the switch lead wires
with suitable connectors.
REMOTE FAN SWITCH
480V + Heaters, require an additional fan relay. (Available as
a kit or factory installed option). The wall switch is packed in the
wiring compartment.
1. Use 18 gauge (min.) NEC Class 1, 600V wiring that meets all
Local and NEC requirements.
2. Install the wall switch in a standard wall box in any convenient
location that is protected from traffic or other accidental damage.
3. Connect the field wire to the switch lead wires with suitable
connectors.
OPTIONAL THERMOSTAT (HVH-TK) Refer to Instruction
Sheet PF204.
Heaters can be equipped with an optional thermostat of the
Bulb and Capillary type for automatic temperature control (Figure
8). The thermostat controls the heating elements and fan simultane-
ously to achieve set temperature.
The “Lo” setting of the thermostat is approximately 40˚F, and
the “Hi” setting is approximately 90˚F.
