SSEMBLY
The heater/fan assembly is standard on the VPD-2WP series pendant PowerDomes. The fan is packed
separately for shipment. The heater comes attached to the ceiling of the housing with its power
connections made.

cable lengths, on page 7, to determine the size and length of the power cable. If the cable used is too
small, the voltage drop across the power line might be excessive and affect the operation of the
PowerDome.
