□
Connect control wiring (if applicable).
□
Run the unit and/or upstream air device to flush out construction debris.
□
Install the pre-filter (if applicable).
□
Install the HEPA/ULPA filter.
□
Turn unit on and adjust airflow to design CFM.
□

Installation
The terminal unit is fully assembled from the factory with the exception
of the HEPA filter and lamps (as applicable) which is shipped in a separate box.
Step 1 -- Carefully remove the unit from the shipping carton and inspect for
damage that may have occurred during shipping. If shipping damage is found,
do not install. Call the manufacturer to report damage.
Step 2 -- Wipe down unit to remove shipping dust and debris.
Step 3 -- Raise unit into ceiling and lower onto gasketed opening.
Gasket should be a closed-cell material approved for the environmental
conditions. It is highly recommended to further support the unit from
above using the tabs welded to the plenum.
Step 4 -- A qualified technician should connect the unit to the appropriate
power supply per applicable codes and standards. Refer to the wiring
diagrams included in these instructions. -FP and -MA units: the electrical
box will be accessible from the plenum side. -MEA units: the electrical
box will be accessible from the roomside.
NOTE
: If an -MA or -MEA unit is installed in an area with no access above the
ceiling, the main power switch
must
be turned on before installing unit
.
NOTE:
An additional disconnect should be added by others per local codes
and regulations.
SSLFHFD-FP-120 --- 120VAC SUPPLY
SSLFHFD-FP-208/240 --- Duel rated 208 or 240VAC SUPPLY
SSLFHFD-FP-277 --- 277VAC SUPPLY
Step 5 -- Blow out / clean entire duct system leading to unit to remove construction
debris. This is especially important for motor accessible units as they do not have a
pre-filter. Wash pre-filter if applicable per “Cleaning the Fan Filter Unit Pre-filter” on page 7.
Step 6 -- Install the HEPA filter per the “Removal and Replacement of the HEPA Filter
with Gel Seal” section.
NOTE: FOR DUCTED INSTALLATIONS, IT IS RECOMMENDED
THAT PRIMARY AIR BALANCING TO ACHIEVE 0.0"WC INLET
STATIC PRESSURE BE DONE BEFORE FAN FILTER UNIT IS
CONNECTED TO DUCT SYSTEM.

FAN FILTER UNITS
A NOTE ABOUT VAV BOXES AND DUCTED APPLICATIONS
In applications where the fan filter unit will be installed downstream of variable airflow devices such as
VAV boxes, air valves, or variable air handlers, proper care in unit set-up needs to be taken.
The unit should not be programmed to run as constant airflow in this application.
Two variable controllers
trying to reach their respective set point will continuously adjust. This will cause issues such as surging,
starving, and eventual shut down of the fan filter unit. The units should be ordered with a constant torque
program. This will remove the dirty filter ramp-up feature and the CFM display will no longer be accurate.
However, this is still preferable to a PSC system due to the energy efficiency of an ECM versus a PSC motor.
Ducted applications
While the fan filter unit can handle some positive or negative static pressure, optimal
performance and reliability will be acheived with an inlet static pressure of 0.0" WC or slightly negative.
To reach an accurate 0.0"WC inlet static, it is recommended that the primary air balancing of the duct system
be done before installing the fan filter unit. When the duct is at optimal static, install the unit per these
instructions and adjust the airflow to the design setting. Verify the airflow with an airflow hood.
It is recommended that all FFUs in the system be energized before any upstream devices to prevent the FFU blower
wheel from spinning backwards. While the motor can generally overcome this, if the airflow needed to overcome
high static is too great, it may not. This will cause the motor to shut down. Continual running of the motor backward
may result in reduced reliability of the EC motor.

Cleaning the Fan Filter Unit Pre-filter
(when applicable)
WARNING!
Disconnect the unit from the electrical power source before attempting to service the unit.
Note: For maximum performance, wash pre-filter every three to six months at a minimum.
Step 1 -- Turn the unit off with the rocker switch located on the unit.
Step 2 -- Disconnect the unit at the power source or at the service panel in
accordance with OSHA (LOTO) practices and procedures.
Step 3 -- Using a driver, remove the screw holding the hinged door. This
allows access to the pre-filter. Slide the pre-filter out of the motor
enclosure. This step is not applicable if unit is non-ducted.
Step 4 -- Wash the filter with hot water and a mild detergent and rinse
thoroughly. Do not use a caustic solution to clean the filter. Blow
dry or let air dry and slide the filter back into the motor enclosure.
Filter should be completely dry before reinstalling into unit.
Step 5 -- Using the driver, re-secure the cover with the screw.

Removal and Replacement of the HEPA Filter with Gel Seal
WARNING!
Disconnect the unit from the electrical power source before attempting to service the unit.
WARNING!
The HEPA filter may be protected by an expanded metal screen. The screen prevents accidental contact with the filter media.
It is not meant to allow handling of the filter by the media. Handle the filter ONLY by the frame.
NOTE: The manufacturer recommends two people to remove and install the HEPA filter in the unit.
Step 1 -- Using a flat screwdriver, release the face frame by rotating the four (4) fasteners a 1/4-turn counter clock-wise.
Unhook the safety cables from the filter clips. Set the frame aside.
Step 2 -- Turn the unit off with the switch located on the unit (round, black button).
Step 3 -- Disconnect the unit at the power source or at the service panel in accordance with OSHA (LOTO)
practices and procedures.
Step 4 -- USE TWO PEOPLE TO SUPPORT THE FILTER and rotate the swingarm filter clips off of the filter until
clip is clear of the filter.
Step 4 ALT (if stud style filter clips) -- Using a 7/16” nut-driver, evenly loosen the nuts holding the filter retaining
clips by working your way around the unit loosening the nuts a little at a time. To make installing the new
filter easier, loosen the nuts until flush with the end of the threaded stud. USE TWO PEOPLE TO SUPPORT
THE FILTER and rotate the filter clips toward the offset hole until clip is clear of the filter.
Step 5 -- Allow gravity to pull the filter away from the unit. If installing a new filter discard the filter in an
appropriate manor.
Step 6 -- Unpack the new filter and inspect for shipping damage. If damage is found, do not install in unit; call the
vendor for replacement arrangements.
Step 7 -- Using two people, raise the filter into place in between the filter guides (or threaded posts if stud style) assuring the seal edge is
approximately in the center of the gel channel.
Step 8 -- While supporting the filter by its frame, rotate the filter clips so that the clips are supporting the frame
and are at 90° to the frame. (ALT--Evenly tighten the nuts by working your way around the unit tightening the nuts
a little at a time. Stop tightening when the aluminum filter frame contacts the stainless steel housing frame of the unit.
DO NOT OVER TIGHTEN
). Wait at least 30 minutes before performing any challenge testing to allow the
gel to fully adhere to the unit.
Step 9 -- Inspect all gaskets and seals for integrity. Reconnect power and turn unit power on.
Step 10 -- Raise the face frame back into place, reattach the safety chains, and secure 1/4-turn fasteners.
