Electrical Installation
1.
Review Electrical Wiring diagram included with heater (typically glued to inside of electrical enclosure door).
2.
Ensure circuit powering the heater has proper capacity. Follow local building codes.
3.
The electric duct heater must have an uninterrupted or unbroken electrical ground to minimize the chance of injury should an
electrical fault occur. This may consist of an electrical wire or approved conduit when installed in accordance with existing
electrical codes.
4.
Review and inspect safety devices.
a.
Automatic Reset – trips if air surrounding the coils is too hot (~130F); will reset itself after cooling (~115F)
b.
Manual Reset – trips if air surrounding coils increases rapidly (~150F); to reset press the red tab towards the reset switch
contacting the protruding metal tab on the relay
i.
If electric coil does not have a red tab, press down the protruding metal tab on the relay by hand
c.
Airflow Switch – trips ON when valve pressure differential is detected
i.
Ensure airflow switch probe points into the air stream
ii.
Note, the airflow switch must be mounted in a vertical plane; if this is not followed, the switch will always output a
constant ON or OFF regardless of airflow
Mechanical Installation
STEP 1
Electric coils are only available in supply orientation and should always be located down
stream of the supply Venturi Valve.
STEP 2
Use the support method prescribed for the duct work in the job specifications.
STEP 3
Connect the provided pressure tubing for the pressure switch to the Hi Pressure tee of the
Venturi Valve.
CAUTION
Disconnect all incoming power before any electrical
installation or service is performed on the unit(s).
