Type HVH Horizontal/Vertical Unit Heater

GENERAL

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.

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 atmo­spheres 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-A­EP (PF490).

ELECTRIC SHOCK HAZARD. Disconnect all power before
installing or servicing heater. Failure to do so could re­sult in personal injury or property damage. Heater must
be installed or serviced by a qualified person in accor­dance 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 circula­tion where each unit supports the air stream from another.

Figure 1 - Single and Multi Unit Mounting

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.)

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. (Refer to
Table B for weights of heater and brackets and for cantilevered force
expressed in foot-pounds.)

Fan blade rotation must be checked. If airflow is not moving out
through the louvers, interchange any two of the three customer power
leads on three-phase units only.

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 or ground lug is provided near the power connection
point (ground Wire on HVH-02 to HVH-20 and ground lug on HVH­25 to HVH-50).

7. Terminals on contactor or on line voltage terminal block are supplied
to be connected to accept the correct size power supply 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 control. 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.

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. 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

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 compres-

sion 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 FAN SWITCH

480V + Heaters require an additional fan relay. (Available as a kit
or factory installed option and standard on heaters 20kW and above).
The wall switch is packed in the wiring compartment.

1. Use 18 gauge (min.) NEC Class 1, 600V wiring that meets all Lo-

cal 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 con-

nectors.

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 simultaneously to
achieve set temperature.

The “Lo” setting of the thermostat is approximately 40˚F, and the
“Hi” setting is approximately 90˚F.
