PLANNING

2.1 Installation zones
The FIN-180B and FIN-180B-HW can be installed in climatic zones 1 to 4 as defined by the Department of Energy (refer to the map below), whether as a stand alone unit or connected to the return 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 the 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 dwelling should not be below 55 °F.

2.2.2 Installation with an AUU
The installer shall ensure that, if necessary, an in-line heater sized according to the 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 continuously running.

PREPARATION

1. Remove the unit from the box and inspect for damage. Installation hardware is located in a plastic bag along with this guide, on top of the filler.
2. Put the unit down on a protected surface.
3. Refer to your local building code to determine the required airflow.
4. Open the unit’s door to access the settings on the electrical compartment cover.
5. Adjust the settings according to the required airflow. The first number around the Airflow Range adjustment is the Low Range CFM value (30-100 CFM), and the second number is the High Range CFM value (110-180 CFM). Use a small flat blade screwdriver to switch from Low Range to High range, and to adjust the CFM value.

? An optional MERV filter may be installed now. The main filter should remain as a prefilter, and the MERV filter should be installed as indicated above.
3.1 MoUntIng the UnIt
? When choosing a location for this unit, keep in mind that maintenance will have to be performed by the end user on a regular basis. Choose an easily accessible location and plan for a 14¼-in. clearance for the door to open.

3.2 Connecting the Insulated ducts to the Unit

1. Slide the inner 6 in. round flexible duct over the port and tie it using a tie-wrap.
2. Pull the insulation over the inner ring of the port without compressing it to minimize possible condensation buildup within the duct, as well as minimize building heat loss and gain.
3. Use duct tape to seal the outer membrane of the insulated duct to the outer ring of the port to create an air-tight path and to minimize building heat loss and gain and reduce the potential for condensation.

? Avoid blocking the test ports with the duct tape.
Test ports

Caution
Make sure to replace insulation around any openings made in the building envelope when installing unit or ducting. Seal insulation with tape or caulk to minimize building heat loss and gain and to reduce the potential for condensation.
⚠warning
Make sure the outdoor intake hood is at least 12 inches above the ground and 6 feet away from any of the following: Dryer exhaust, high-efficiency furnace vent, central vacuum vent, gas meter exhaust, gas barbecue-grill, any exhaust from a combustion source,
garbage bin and any other source of contamination.
? Make sure that the outdoor intake hood is easily accessible for annual maintenance. If located above the first floor, place it close to a window or balcony to allow ease of access.
IMPORTANT – The ducting from this fan to the outside of the building has a strong effect on the air flow, noise and energy use of the fan. Use the shortest, straightest duct routing possible for best performance, and avoid installing the fan with smaller ducts than recommended. Insulation around the ducts can reduce energy loss and inhibit mold growth. Fans installed with existing ducts may not achieve their rated airflow.
