Subbase (Optional)
The Subbase provides an enclosure for an electrical receptacle, power switch and a circuit breaker. Electrical
connections to the power supply from the unit are made inside the subbase. In addition, the subbase provides
structural support to the Wall Sleeve and to the weight of the PTAC unit .
The Subbase kit consists of two leveling legs for sleeve support and an accurate unit for leveling during instal-
lation. Also, the subbase is pre-wired and is grounded by means of a grounding screw.
