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.

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.

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.

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.
