1.1 The PH enclosure heater is a fan forced air heater designed to
maintain a suitable temperature inside a metal enclosure or control
panel.
1.2 The proper selection of a heater for an enclosure or space is
determined by a consideration of the surface area, insulation properties,
temperature difference between the ambient and the enclosure, and
the enclosure location. To ensure proper heater selection, refer to
“Heater Selection” guidelines.
1.3 The intended use of this heater is to protect against the effects
of low temperature such as corrosion, freezing or condensation from
damaging critical components inside a control enclosure.
1.4 This heater is not designed for use as a space or comfort heater
and should not be installed in a wet, dusty, corrosive or hazardous
location.
1.5 Operating surface temperatures of this heater is sufficient to cause
burns upon contact with bare skin.
1.6 Before servicing, disconnect heater from the supply and allow
approximately 10 minutes for the heater to cool.
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.
INSTALLATION
2.1 The heater is to be mounted on a metal surface only inside a metal
enclosure and should be installed in the centre of the enclosure and as
low as practical for the best possible heat distribution.
2.2 The heater should be mounted in a vertical position with the
terminal block at the bottom, so that the air discharge vents are at the
top.
2.3 To ensure unrestricted air flow through the heater and avoid high
temperatures on adjacent surfaces, heat sensitive components should
be spaced away from the air discharge vents as shown below.
2.4 Mount the heater to the enclosure using four #10 metal screws. An
optional DIN rail mounting adaptor is available.
INSTALLATION
3.1 Disconnect power before installation or servicing.
3.2 Heaters must be wired by qualified personnel to local electrical
code requirements.
3.3 Check the supply voltage requirements with the heater nameplate
voltage rating. Use wires suitable for 90°C.
3.4 Note that the heater thermostat does not have an OFF position.

WIRING
3.1 Disconnect power before installation or servicing.
3.2 Heaters must be wired by qualified personnel to local electrical
code requirements.
3.3 Check the supply voltage requirements with the heater nameplate
voltage rating. Use wires suitable for 90°C.
3.4 Note that the heater thermostat does not have an OFF position.
OPERATION AND MAINTENANCE
4.1 Apply power to the circuit. Set the thermostat to the desired
space temperature.
4.2 Allow suitable time for the thermostat to cycle and the space
temperature to stabilize.
4.3 Due to system variances, you may need to readjust the thermostat
to achieve desired temperature.
4.4 To ensure proper air flow through the heater, periodically check
and clean the air ventilation openings from any dust or debris.
4.5 Standard heaters have a built-in pilot light to indicate heat on, and
have a built-in fan switch which will allow the fan to run continuously
for more uniform temperature distribution.
4.6 In “Fan” mode the heater will still provide heat when the temperature
drops below set point. In the “Auto” mode the fan will turn on only when
the heating element is energized.
4.7 The fan motor has permanently lubricated ball bearings and
should not require maintenance.
OVERHEAT PROTECTION
In the event of fan failure, or an overheat condition, an automatic reset
temperature limit switch will open, breaking the power to the heating
element.

• DO NOT INSTALL IN WET, DUSTY, CORROSIVE OR HAZARDOUS
LOCATIONS.
• MOUNT ONLY ON A METAL SURFACE IN A METAL ENCLOSURE.
• HEATER SURFACE TEMPERATURES ARE SUFFICIENT TO CAUSE
BURNS.
• KEEP AWAY FROM COMBUSTIBLE SURFACES AND HEAT SENSITIVE
COMPONENTS.
