Mounting the Receiver
1) Connect the receiver connector to the socket
located outside the electrical box. (Fig. 9)
7-3. Increasing the Fan Speed
If external static pressure is too great (due to long
extension of ducts, for example), the air flow volume
may drop too low at each air outlet. This problem may
be solved by increasing the fan speed shifting the static
pressure switch from L to H. (Fig. 10)
Do not allow inter-unit wiring to
come in contact with pooled
water in the drain pan. A severe
shock hazard can occur,
leading to injury or death
