SELECTION (continued)
HIGH RECOVERY MODELS
High recovery heaters operate as standard PTC2 heaters with the addition of a changeover to 400 watt
operation at colder temperatures (see Chart 4 on page 7).
TEMPERATURE ACTIVATED MODELS
Temperature activated heaters operate as standard PTC2 heaters except the heater deactivates at higher
ambient conditions (see Chart 4 on page 7).
INSTALLATION
Installation of the PTC2 heater requires mounting of the heater body and connection of the power wiring
harness. In all heater systems, including the temperature activated and high recovery models, the final
connection is two wire.
ELECTRICAL CONNECTIONS
CAUTION
The fan-forced systems are NOT dual voltage devices and must be selected based
upon operating voltage. Ensure that the voltage printed on the heater label matches the
supply voltage before energizing the heater assembly.
The heater system is provided as a pre-wired heater with a
12 foot, two-wire power harness. On 200 watt through 400
watt models, the heater mates to the power harness with a
quick-connect plug (see Figure 1 at right) which simplifies
heater mounting and power wire installation. The two-wire
harness is connected directly to the 120V or 240V power
source. No ground wire is required.
20 watt through 60 watt heaters do not include wire harness
and should be installed with 22 AWG or heavier wire via the
two terminal blocks integral to the heater.
