c). Installation work and electrical wiring must be done by a qualified person(s) in accordance with all applicable codes and standards, including
fire-rated construction codes and standards.
d). Sufficient air is needed for proper combustion and exhausting of gases through the flue (chimney) of fuel burning equipment to prevent backdrafting.
Follow the heating equipment manufacturer’s guideline and safety standards such as those published by the National Fire Protection Association
(NFPA),and the American Society for Heating, Refrigeration and Air Conditioning Engineers (ASHRAE), and the local code authorities.
e). When cutting or drilling into wall or ceiling, do not damage electrical wiring and other hidden utilities.
f). Ducted fans must always be vented to the outdoors.
g). Acceptable for use over a tub or shower when connected to a GFCI (Ground Fault Circuit Interrupter) - protected branch

See “Connect Wiring” for details.
The control box, located inside the fan housing, has three separate adjustments:
(1) the low airflow knob adjusts the lower airflow from 30 CFM up to the air flow rate of the high fan speed determined by the toggle switch setting.
The low speed is de-activated when set between OFF-30 CFM (factory set to OFF).
(2) (Only for SAS-80DC3H SAS-80DC3HM) the humidity sensor knob set user-adjustable setpoint. The humidity sensor is de-activated when set
between OFF-30% (factory set to 80% (Ambient temperature of 25
℃
)).
(Only for SAS-80DC3) The time delay knob is adjustable from 3 to 30 minutes and will switch the fan to the low speed setting after the
switch
II
is turned off for the set period of time.
The time delay setting is de-activated when set between OFF-3 mins (factory set to OFF).
(3) The toggle switch will adjust the upper fan speed setting from 50 to 100 CFM. (factory set to 100CFM).
