Lifebreath CLEAN AIR FURNACE 60ELE - Manual (Page 13)

Heating/Cooling
When the room thermostat calls for heat, the furnace
blower switches on to heating speed and will start circu-
lating air across the coil, which picks up heat and
delivers it to the rest of your home.
Once the thermostat's temperature is reached the ele-
ments will shut off, and the blower will return to its
pre-set speed or off.
Note: When the furnace blower is left running on
low speed the air in the home circulates continu-
ously. When the heat is called for the blower will
automatically switch to a higher speed. After the
required hot air has been delivered the blower will
switch back to low speed.
When the thermostat calls for cooling (optional A coil
and condensing unit required) the furnace blower acti-
vates to high speed and the outdoor condenser unit is
energized. After the thermostat temperature is reached
the condensing unit will shut off, and the blower will
return to its low speed. Continuous low speed is selec-
table, (fig. 6).
Ventilation
The heat recovery ventilation (HRV) portion of the Clean
Air Furnace, is automatic. Once set, a desired amount
of fresh air will be drawn into the home while the fur-
nace blower is activated.
To reduce humidity increased ventilation may be
required. An optional remote dehumidistat can be
installed. The dehumidistat will increase the speed of
the furnace blower to high and will return to its original
setting when humidity levels decrease. Your dehumidis-
tat must be switched off during warmer months as it is
not required for air conditioning operation. To increase
humidity a quality humidifier should be added to the sys-
tem.
Typically the air flow for ventilation will be set to 50 -
70cfm, for low speed furnace operation, and
100 - 150cfm at high speed. The pleated furnace filter
should be checked regularly and replaced as needed.
The HRV filter should be washed twice a year or more
often if needed.
