USER SERVICING INSTRUCTIONS
• The metal filter included with this unit should be cleaned every 6 months using water and a mild soap. To
remove the filter(s), open the door, release the filter retaining clip and pull filter(s) out. Allow the filter to dry
completely before putting it back in the unit; when reinserting it in the unit, make sure that it is standing
straight.
• Inspect the outdoor air intake at least once a year.
• During the first year of operation, it is recommended to inspect your unit at a higher frequency, especially if
you live near a highway or in an area where there is a lot of construction work, generating lots of dust. Your
filter(s) may need more frequent cleaning or replacement in these types of environments.
• Replace the optional MERV filters at least once a year; do not attempt to clean and reuse the optional
MERV filters.
• These recommendations may change according to the environmental conditions in your area.
1. PREPARE THE UNIT
1. Open the unit's door to access the settings on the electrical compartment cover.
2. 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.
2. INSTALL BRACKETS ACCORDING TO YOUR INSTALLATION TYPE
Using 4 screws no. 8-18 x 0.375 in., install the brackets on the unit as on of the ways illustrated below.
��
For a 16-in. or 24-in. cc joists installation, use the optional bracket FIN-S1624 (see instructions packed
with bracket).

8. When cutting or drilling into a wall or ceiling, do not damage electrical wiring and other hidden utilities.
9. ALL UNITS: This unit must be grounded. FIN-180B MODEL ONLY: The power supply cord has a 3-prong
grounding plug for your personal safety. It must be plugged into a mating 3-prong grounding receptacle,
grounded in accordance with the national electrical code and local codes and ordinances. Do not remove
the ground prong. Do not use an extension cord.
10. When servicing, cleaning or performing installation of this unit, it is recommended to wear safety glasses
and gloves.
11. When applicable local regulation comprises more restrictive installation and/or certification requirements,
the aforementioned requirements prevail on those of this document and the installer agrees to conform to
these at his own expense.
12. The unit must be mounted at least 3.3 feet (1.0 meter) away from any accessible opening of the duct.
CAUTION
1. Please read specification label on product for further information and requirements.
2. Do not intake air into spaces within walls or ceiling or into attics, crawl spaces, or garage. Do not attempt
to recover the exhaust air from a dryer or a range hood.
3. Intended for residential installation only in accordance with the requirements of NFPA 90B.
4. When leaving the house for a long period of time (more than two weeks), a responsible person should
regularly check if the unit operates adequately.
5. At least once a year, the unit mechanical and electronic parts should be inspected by qualified service
personnel.
6. Since the electronic control system of the unit uses a microprocessor, it may not operate correctly because
of external noise or very short power failure. If this happens, turn power off at service panel and wait
approximately10 seconds. Then, restore the power to the unit.
7. Outdoor intake hood must be weather tight and comprise a bird screen.
8. Should you decide to dispose of this unit or of parts of it, do so in accordance with local laws and regulation.
9. Some areas are prone to a higher frequency of lightning-induced power surges. Using a surge protector
device to protect units located in these areas is recommended.
3. INSTALLER CONSIDERATIONS
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.
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.
4. 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

range range
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.

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
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
��
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.
5. POWERING THE UNIT
��

If desired, the power can be related to an ON/OFF wall switch. Do not use this unit with a dimmer switch
or any other type of control.

Connect the power cord to a wall outlet.
5.2 Fin-180B-HW
Risk of electric shock. Electrical wiring must be done by qualified personnel in accordance with
all applicable codes and standards. Before connecting wires, switch power off at service panel
and lock service disconnecting means to prevent power from being switched on accidentally.
1. Detach the electrical compartment cover from the unit by removing its retaining screw.
2. Install the included wire clamp on the unit. Insert the house wiring cable through the wire clamp and
tighten the wire clamp to secure the cable.
3. Using provided wire connectors, connect wires as follows: BLACK to BLACK, WHITE to WHITE and
GREEN or BARE wire under GREEN ground screw. DO NOT FORGET TO CONNECT THE GROUND.
4. Put back in place the electrical compartment cover, taking care not to pinch wires. Restore power at
service panel.

6. TEST THE UNIT
You may test the unit at this point using the test port on the intake side (closest to the filter) and a Pitot tube.
The distance between the test port and the center of the duct is 3.75 inches.
��
If the unit is connected to an AHU,
make sure that the AHU is not running
while measuring the airflow.
