INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS FOR

SERIES OK3 – INFRARED RADIANT HEATERS

FIRE/EXPLOSION HAZARD WARNING - During operation, take precautions to ensure that

combustible materials are always kept at a safe distance from the radiant energy. This heater is

not intended for use in hazardous areas where flammable vapours, gases or liquids or other

combustibles are present. Remember that objects placed under an infrared heater can take a while

to reach stabilized temperatures. If you are unsure of the suitability of the heater for the intended

application, check with the factory for recommendations. Failure to comply can result in personal

injury and/or property damage.

DESCRIPTION

1.0 The OK3 radiant heaters are suitable for comfort heating

use in non-hazardous areas protected from rain, snow or splashing,

where heating element temperatures in excess of 750°C(1382°F)

will not present the risk of fire or explosion. The heater does not

present a safety hazard when it is installed, operated and maintained

in accordance with these instructions.

2.0 The OK3 heater has two U-shaped metal sheath heating

elements factory interconnected in series or parallel depending on

voltage. Never change heaters which have been

factory series

connected to a parallel connection.

3.0 Minimum space clearances from combustibles, when

heaters are horizontally mounted and installed, as listed in Table 1

following.

Table 1

Min. Spacing

From nearest wall 600 mm (24”)

From the ceiling 300 mm (12”)

INSTALLATION

The system designer is responsible for

the safety of this equipment and

adequate back-up controls and safety

devices must be installed. Failure to

comply could result in personal injury

and/or property damage.

Heaters must be wired by qualified

personnel in compliance with local

codes.

5.0 Verify that the nameplate voltage and wattage are suitable

for use on the available electrical power supply. Do not connect

the heater to an electrical supply voltage other than shown on the

product label.

Insulation contamination or moisture

accumulation can cause fault to the

element sheath generating arcing and

releasing molten metal. Install proper

ground fault protection to prevent

personal injury and/or property

damage.

6.0 The connection box volume is 3100 cm³(190 in³).

7.0 Supply conductors to the heater must be suitable for

110°C(230°C). The ground wire from the supply shall be connected

to the grounding connection located in the connection box.

8.0 The connection box has eight dual knockouts, ½" or ¾"

and two dual knockouts ¾" or 1". The standard Type 1 enclosure

is suitable for dry, indoor locations only in non-corrosive

environments.

9.0 For short circuit protection, heaters must be installed with

proper fast acting fuses or breakers as close as possible to the

ratings indicated on the nameplates, in compliance with the local

electrical codes.

4.0 To facilitate mounting, the heater has four ¼"-20 mounting

holes located at each top corner of the housing. Either chain

mounting (use eye bolts) or bolting to a non-combustible sliding

support (slotted holes) is adequate provided that the spacing

instructions as given in 3.0 are followed. Chain mounting is preferred

since rigidly mounted heaters are susceptible to warping.

FIG. 1 – MOUNTING CLEARANCES

Operating surface temperature of the heater

is sufcient to cause burns upon contact with

bare skin. Before servicing, allow sufcient time

for the heater to cool.

1.1 The PXF heater is designed to maintain a suitable temperature

inside a control enclosure, pump house or a similar space. The

PXF is not designed for use in wooden cabinets or enclosures.

The heavy duty industrial grade design, with its high surface area

aluminum emitter, eliminates the need for a fan while providing low

radiation and high convection heating to the enclosure or space.

1.2 Type PXF heaters are available with or without a built-in

thermostat. Units with thermostat have a “T” following the PXF

catalog designation.

1.3 The PXF has a general purpose terminal enclosure which is

not suitable for wet or hazardous locations.

1.4 Use the mounting bracket supplied to ensure that the minimum

spacing between the heater and adjacent walls or oor is

maintained. If mounted vertically, the terminal box must be located

at the bottom.

1.5 To attach the mounting bracket, slide the bracket between the

two rear ns. Tighten the mounting screw such that it squeezes

the head of the mounting screw tight against the heatsink n,

preventing movement.

1.6 In control enclosures, the spacing between the heater and

temperature sensitive components should be 4” minimum around

all sides.

INSTALLATION

1.7 Heaters without a factory installed temperature control

thermostat that are to be installed in UL Listed Industrial Control

Panels, must be used in conjunction with a UL Recognized

thermostat suitable for use in UL508A Industrial Control Panels,

and installed per the requirements of UL 508A.

2.1 DISCONNECT POWER BEFORE INSTALLATION OR

SERVICING.

2.2 Heaters must be wired by qualied personnel to electrical code

requirements.

2.3 Check supply voltage for compliance with heater nameplate

voltage.

2.4 A 7/8” diameter hole in the terminal box is provided to allow

wiring through a ½” conduit tting. Use supply wires suitable for

90°C.

2.5 When temperature regulation is required, the PXFT (with built-

in thermostat) can be wired to control itself plus one or more ba

ensure the maximum current rating of the thermostat, 25 Amps, is

not exceeded.

2.6 The thermostat is a single pole device and cannot be used for

disconnecting means.

heatsink fin, preventing movement.

1.6 In control enclosures, the spacing between the heater

and temperature sensitive components should be 4” minimum

around all sides.

Operating surface temperature of the heater

is sufficient to cause burns upon contact with

bare skin. Before servicing, allow sufficient

more basic PXF heaters. In multiple heater installations

ensure the maximum current rating of the thermostat, 25

Amps, is not exceeded.

2.6 The thermostat is a single pole device and cannot be

used for disconnecting means.
