Control and Installation
Control/Timer
- Optional Decora-style wall-mounted control/timer (SA-LT15).
- Modes: INTERMITENT (20-40 minutes), CONTINUOUS, OFF, Timer (20-40-60 minutes).
Installation
- Can be ceiling-mounted or suspended.
- Easily installed in the ceiling void or just below a fire-rated ceiling.
- Set of nylon suspension straps included for installation.
- Optional steel mounting plate for Top Port models (SA-P5R).
- Furnace interconnect plug connector factory installed.
Setting and Balancing
Balance the unit using the supplied "Balancing" instruction. The installer needs required flow rates, a manometer, and approximately 5 minutes to adjust and balance the system. Specify air flow rates for LOW SPEED and HIGH SPEED. The system's static pressure should ideally be less than or equal to the static pressure indicated by the graph for HIGH SPEED. The unit's electronic adjustments allow for fine-tuning flow rates without external devices.

Application
The OSALE115 is an ideal solution for high-rise apartments and small to medium-sized homes, particularly when regulations do not require unit certification at -25°C (-13 °F). It purifies the air by expelling many pollutants, dust, and allergens to the outside, while ensuring an equivalent supply of fresh air into the home.
