If it is desirable to mount the UC1 more than 2 feet from the Fan Proving Switch an additional electrical junction box and appropriate length of conduit will be necessary. Any added wire should be 14 gage and a pig tail should be added to each ground wire connection so that each electrical junction box is grounded. See diagram on page 8 for a typical UC1, Fan Prover and Venter installation. MODELS HS4 & HS5 (ONLY) Connect Black and White motor ring terminal leads to ring terminal studs on motor. As viewed from the opposite end of the shaft (rear of motor), the motor should rotate clockwise.
