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.

Filter Replacement

WARNING:
For applications involving risk of exposure to harmful particulates or pathogens in the filter media, use appropriate PPE and reference your facility’s protocol for safe removal and disposal of filters.

1. Disconnect the fan/filter unit from the PDM.

2. Attach double stick tape to a polypropylene panel – place on all four sides.
   The panel protects the HEPA filter from damage (Figure 1).

3. Place the polypropylene panel over the filter screen, making sure that it only adheres to the screen without overlapped the edges.

4. Push one side of the FFU up, rotate it 90° and lower through the ceiling grid.

5. Place the unit on a flat work surface and remove the sheet metal screws that hold the HEPA filter to the case.

6. Replace with a new HEPA filter carefully handling edges only.

7. Secure filter to the case with the same screws previously used.

8. Place unit back onto the ceiling grid.
