1.0 Installation
The Fan/Filter Unit is designed to fit on top of a Terra standard 2’ x 4’ clean room ceiling
grid. It includes a threaded fixture at each corner to accommodate four eye-bolts (not
provided) that can be used to assist in positioning the unit.
WARNING: To reduce the risk of fire, electric shock, or injury to persons,
observe the following:
A) Use this unit only in the manner intended by the manufacturer. If you have
questions, contact the manufacturer.
B) Before servicing or cleaning unit, or replacing a filter, switch power OFF at the
service panel and lock the service disconnecting means to prevent power from
being accidentally switched on. When the service disconnecting means cannot be
locked, securely fasten a prominent warning device, such as a tag, to the service
panel.
C) When the removal/disconnection of either filter is required due to service or
component replacement, the replacements are to be remounted as previously
installed.
D) Installation work and electrical wiring must be done by qualified person(s) in
accordance with all applicable codes and standards, including fire-rated
construction. All metal components must be properly grounded.
E) When cutting or drilling into a wall or ceiling, do not damage electrical wiring and
other hidden utilities.
2.0 120V vs. 220V Configuration
CAUTION: Double check your FFU is configured for the correct voltage.
Connecting the motor to the wrong voltage can permanently damage and
break the motor. The FFU is pre-configured for 120V. It can be easily
reconfigured to 230V.
3.0 Initial Start-Up
WARNING: Keep unit disconnected from power supply during inspection.
Prior to providing power to the unit, check that no damage has occurred during shipping.
Conduct a visual check to make sure there are no visible dents or penetrations. If the
unit is intact, remove the pre-filter and fan guard screen. Once the battery is plugged in,
it will automatically start charging and take 1.5 –2 days to fully charge.
To start unit, plug the UPS into a live AC wall outlet and then press and hold the
POWER button for about one second. If there is no utility power, you can “cold-start”the
UPS (turn it ON and supply power for a limited time from its batteries) by pressing and
holding the POWER button for about two seconds (alarm will beep once after interval
has passed).
Do not unplug the UPS to test its batteries. This will remove safe electrical
grounding and may introduce a damaging surge into the network
connections.
4.0 Operation
The unit consists of a 1/3-HP electronically commutative motor driving a forward-curved
centrifugal impeller. Air is drawn into the unit through a pleated pre-filter and in turn to
an insulated chamber where it is then directed to an exit HEPA filter with a built-in
diffuser. The battery system provides approximately 1-2 hours runtime depending
on FFU speed setting. The external battery can be “hot-swapped” (safely removed or
swapped without shutting down the UPS).
The unit can also be equipped with a 3/8”-diameter challenge port, which can be used to
take differential pressure measurements to monitor filter performance or insert aerosols
for leak-test certification. Port is capped when not in use.
120V Configuration
1. Black and Red wires are connected to the same terminal.
2. Yellow Jumper Cable is installed.
220V Configuration
1. Black and Red wires connect to the upper terminal as shown.
2. Yellow Jumper Cable is removed.

5.0 Cleaning and Maintenance
WARNING: Disconnect from power supply before servicing unit or replacing
filters. When servicing or replacing either filter, the new filter is to be
installed in the same manner as the filter it replaces.
The scheduled maintenance of the unit depends on the installed location and consists of
cleaning or changing the pre-filter and the HEPA filter. It is recommended that the pre-
filter be inspected and cleaned every three months or sooner depending on the
cleanliness of the external environment. The HEPA filter cannot be cleaned and must be
replaced when the air velocity falls below 70 feet/min.
Changing the HEPA filter requires removal of the unit from the ceiling grid. Place the
unit on a flat work surface and remove the 10 sheet metal screws that hold the HEPA
filter to the case. Replace the filter with a new one and secure it to the case with the
same screws before placing it back onto the ceiling grid.
6.0 Warranty
Products Manufactured by Terra: Terra Universal, Inc., warrants products that it
manufactures to be free from defects for a period of 12 months for parts and 90 days for
labor, commencing from the date of shipment. This limited warranty covers parts and
labor, but not transportation and insurance charges. Terra’s sole responsibility is to
repair or replace, at its option, any part of the product that proves defective or
malfunctioning during this time limit. In some cases, components incorporated in Terra
Universal products are covered by additional warranties from component
manufacturers; obtain specific information from Terra sales representatives. Repairs
may be completed by 3rd party service agents approved by Terra Universal. Terra
Universal reserves the rights to limit this warranty based on a service agent’s travel,
working hours, the site’s entry restrictions and unobstructed access to serviceable
components of the product. This warranty is void if the equipment is abused or modified
by the customer, is operated outside Terra’s operating instructions or specifications, or
is used in any application other than that for which it is specified. This warranty does not
include routine maintenance or service procedures, shipping damage, nor damage from
misuse, intentional or unintentional abuse, neglect, natural disasters, or acts of God.
Products Manufactured by Others: Terra Universal, Inc., warrants that, to the best of its
ability, Terra’s representations of products that are manufactured by others reflect the
manufacturer’s representations, subject to change without notice. Sole warranty for
these products is the original manufacturer’s warranty that is passed forward to the
purchaser and constitutes the customer’s sole remedy for these products. Detailed
warranties for distributed products are available through Terra sales representatives.
Freight Shortage or Damage: Upon receipt of any equipment from Terra Universal,
Inc., customer shall immediately unpack and inspect for damage or shortage. The
customer shall not accept a damaged package or a short shipment until the carrier
makes a "damage or shortage" notation on both the carrier's and customer's copy of the
freight bill or delivery receipt. Service title passes when the shipment is loaded, so
customer is responsible for filing and collecting a freight claim. Any replacement
products must be ordered and paid for separately. For Terra's "Policy and Procedures
for Returning Goods," see Terra's Internet site: www.TerraUniversal.com.
Generally, customers can improve the chance of collecting on a freight claim by
following these procedures: 1) formally requesting that the carrier inspect the shipment
immediately upon suspecting damage or shortage to verify condition; 2) notifying the

Indicator Lights
“Output Load Level” LEDs: These multicolored LEDs indicate the
approximate electrical load of equipment connected to the UPS’s AC
outlets: green (light load), yellow (medium load), and red (overload). If the
red LED is illuminated continuously or flashing, clear the overload
immediately by unplugging some of the equipment from the outlets until the
yellow or green LED illuminates.
-Any overload that is not corrected by the user immediately may cause
the UPS to shut down and cease supplying output power in the event
of a blackout or severe brownout.
“Power” LED: This green LED lights continuously when the UPS is ON and
supplying connected equipment with AC power from a utility source. The
LED flashes and an alarm sounds (4 short beeps followed by a pause) to
indicate the UPS is operating from its internal batteries during a blackout or
a severe brownout.
“Voltage Correction” LED: This green LED lights continuously whenever
the UPS is automatically correcting high or low AC voltage on the utility line
without using the battery power. The UPS will also emit a slight clicking
noise.
“Battery Warning” LED: This LED lights yellow and an alarm sounds
intermittently after self-test is initiated to indicate the UPS batteries need to
be recharged or replaced.
“Battery Charge” LEDs: When the UPS is operating from utility power,
these LEDs indicates the approximate charge state of the UPS’s internal
batteries: red indicates the batteries are beginning to charge; yellow
indicates the batteries are roughly midway through charging; and green
indicates the battery are fully charged.
Silence or “mute” UPS alarms: Briefly press and release the MUTE/TEST
button.
-Continuous alarms (warning to immediately shut down connected
equipment) cannot be silenced.
