2. PLANNING
2.1 INSTALLATION ZONES
Both FIN-180P and FIN-180P-HW units can be installed in climatic zones 1 to 4 as defined by the
Department of Energy (refer to Appendix A for the map), whether as a stand alone unit or connected to the
ducting of an AHU. Installation in any other climatic zone may cause damage to the house.
2.2 INSTALLATION TYPES
CAUTION
Always use insulated ducting of a minimum R-4 insulation factor.
2.2.1 STAND ALONE INSTALLATION
The installer shall ensure that, if necessary, an in-line heater sized according to required airflow and outside
design heating temperature from Manual J or ASHRAE table is installed to avoid condensation on
uninsulated duct distribution systems within the house or surfaces near the distribution register. The in-line
heater shall have an integrated airflow sensor and an over temperature sensor to prevent heating in no-flow
or low-flow conditions.
When deciding if a preheater is required and
whether it should be installed BEFORE or
AFTER the supply fan, consider the following:
• This supply fan’s minimum operating
temperature is 14 °F.
• The minimum distance between the
preheater and the supply fan is 12 inches.
• The temperature distributed in the ducting
should not be below 55 °F.
2.2.2 INSTALLATION WITH AN AHU
The installer shall ensure that, if necessary, an
in-line heater sized according to required airflow
and outside design heating temperature from Manual J or ASHRAE table is installed to ensure that the air
delivered to the AHU is never below the minimum temperature allowed by the manufacturer (generally 55
°F). The in-line heater shall have an integrated airflow sensor and an over temperature sensor to prevent
heating in no-flow or low-flow conditions.
When deciding if a preheater is required and whether it should be installed BEFORE or AFTER the supply
fan, consider the following:
• This supply fan’s minimum operating temperature is 14 °F.
• The minimum distance between the preheater and
the supply fan is 12 inches.
• The temperature distributed in the ducting
should not be below 55 °F, unless the
AHU blower is always running when
the supply fan runs. Refer to
section 4.2 for wiring
configurations.
