Introduction
This manual provides information on installing and operating Terra Universal’s Low Profile WhisperFlow® Fan/Filter Unit. The Fan/Filter unit provides a steady laminar flow stream of HEPA filtered air to the area below the mounted unit. By studying this document carefully, you can be assured of a long, efficient service life from the unit.
Operation
The unit consists of a 1/6 HP, thermally protected, variable speed motor that provides precise, fully adjustable airflow and drives a backward-curved centrifugal blower. The motor is controlled by an electrical speed dial control. This dial can function as ON/OFF for the blower and starts from high to low flow rates.
Installation
The Low Profile Flow Fan/Filter unit is designed to fit on top of a Terra
Laminar Flow Hood or cleanrooms with restricted height areas. The low profile
FFU height is 8” compared to the standard FFU height at 12.584”. The 4-pin
connector allows for easy installation to Terra cleanrooms (connector may be
used with an optional wall plug adapter; or may be removed entirely to hard-
wire the FFU).
WARNING:
To reduce the risk of fire, electric shock, or injury to persons, do not use
this fan with any solid-state speed control device, and 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, switch power off at service panel and
lock the service disconnecting means to prevent power from being switched on
accidentally.
When the service disconnecting means cannot be locked, securely fasten a
prominent warning device, such as a tag, to the service panel.
C) Installation work and electrical wiring must be done by qualified person(s)
in accordance with all applicable codes and standards, including fire-rated
construction.
D) If the supply cord is damaged, it must be replaced by the manufacturer, its
service agent, or similarly qualified persons in order to avoid a hazard.
E) When cutting or drilling into a wall or ceiling, do not damage electrical
wiring and other hidden utilities.
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.
This can be accomplished via a visual check to make sure there are no visible
dents or penetrations. If the unit is intact, rotate the fan wheel to make
sure it is not in contact with any stationary parts and that there are no
visible loose screws or bolts obstructing the wheel’s rotation. After
installation, with power applied, the fan will rotate and filtered air will
exit the HEPA filter.
Cleaning and Maintenance
WARNING:
Disconnect from power supply before servicing unit. When replacing 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 changing the HEPA filter. The HEPA filter cannot be cleaned and
must be replaced when the laminar flow rate falls below 70 feet/min.
