immediately disconnected from power and returned to Novaerus.
CAUTION: Do not use outdoors or near water.
CAUTION: Not to be used by persons (including children) with reduced physical,
sensory or mental capabilities, or lack of experience and knowledge,
unless they have been given supervision or instruction.
CAUTION: To reduce the risk of electric shock, this equipment has a grounding
type plug that has a third (grounding) pin. This plug will only t into a
grounding type power outlet. If the plug does not t into the outlet,
contact qualied personnel to install the proper outlet. Do not alter
the plug in any way.
CAUTION: Use of this equipment adjacent to or stacked with other equipment
should be avoided because it could result in improper operation. If
such use is necessary, this equipment and the other equipment should
be observed to verify that they are operating normally.
CAUTION: Portable RF communications equipment (including peripherals such
as antenna cables and external antennas) should be used no closer
than 12 inches (30 cm) to any part of the Protect 900, including
cables specied by the manufacturer. Otherwise, degradation of the

7. Instructions for Use
The product should be placed in a dry location and connected to a suitable
grounded outlet. The product is intended to be wall mounted or placed on a
stand. Please follow the wall mounting instructions included in this document.
Once the product is installed, turn the power switch to the on position. The
device is now operating and the blue light will be illuminated. The product
includes a fan speed switch to allow the product to be set on a slow or high
speed. Roman numeral I indicates slow speed, Roman numeral II indicates high

8. Wall Mounting Instructions
The mounting of this product shall be conducted by a person that is experienced
with the proper use of standard installation tools such as a drill, screw driver,
tape measure and level. The unit should be installed approximately two third’s up
the wall.
The product can be wall mounted using suitable fasteners for the corresponding
wall type. Fix the screws horizontally with a spacing of 7-1/8" (180 mm). Leave
the screw head protruding no more than 0.5" (12 mm) from the wall for hanging.
Ensure screws are tightly secured into the wall and a solid connection is made
between the screws and the unit. Ensure the product is level. Follow these
instructions depending upon mounting surface:
Hollow Wall Construction
For hollow wall installations studded with metal or wood framing and sheathed
with drywall, plaster, or plywood, an appropriate hollow wall xing such as a #10
re-usable anchor should be used.
Each of the two re-usable anchors used must be rated for a 20.0 lb. (9.1 kg)
rating minimum, and be the appropriate size for the sheathing thickness. Use #10
size minimum.
Typical drill size is 3/8" (9.5 mm) for the #10 re-usable anchor shown. Follow
manufacturer’s instructions.

For Concrete or Masonry Wall Construction
Use purposed 3/16" (4. 8 mm) concrete screws.
Each of the two screws must be rated for 20.0 lb (9.1 kg) minimum.
Typical drill size is 5/32" (4 mm) for the 3/16" (4.8 mm) concrete screw. Follow
manufacturer’s instructions and recommendation for drill depth for screws being
used.
Various types of concrete inserts are available that are adequate for use in
concrete, such as conical lead or anged polypropylene that will be adequate for
installation of the rack mount bracket. They must be individually rated to support
20.0 lb (9.1 kg) minimum.
Use sizes that support a #10 screw minimum.
Typical drill size is 5/16" (8 mm) for the #10 conical lead anchor for concrete.

9. Service and Maintenance Instructions
Clean the body of the Protect 900 regularly to prevent dust from collecting.
1. Wipe away dust from the body of the device with a soft dry cloth.
2. Clean the air outlet with a soft dry cloth.
Air Intake Screen
Cleaning of the air intake screen is recommended monthly. To clean the air
intake screen, use a standard vacuum cleaner brush or compressed air in an open
ventilated area to blow the dust off the screen.
Use a bowl of soapy water to hand wash the scrim. While wearing gloves,
remove the scrim and soak for 5 minutes. Pat dry before replacing the scrim and
dispose of gloves.
It is recommended that the user inspect the air intake screen bi-weekly in the
rst 2 months of use to determine the most appropriate cleaning period for its
facility. If dust and debris has collected on the intake screen sufcient enough to
cause a signicant decrease in airow, more frequent cleaning may be required.
The air intake screen can be removed by pulling on the
cloth tab attached to the screen frame. The air intake
screen is removed from the top of the device. See image
with arrow indicating location of screen tab.
Replacingthescreen
When replacing the screen, please ensure that the screen is pushed down in the
track completely to ensure the air intake is completely covered by the screen.
You will feel the screen stop once it is fully inserted; no part of the screen frame
should be sticking out from the top of the unit.

The metal frame grid should be facing towards the rear of device as shown in the
image below.
An additional screen has been provided for each unit to allow for rotation during
the cleaning process. The Protect 900 unit should not be operated without the
air intake screen in place.
Service
Do not open the tamper proof screws on the casing of the unit. No serviceable
parts are contained within. The units should be opened by qualied Novaerus
personnel only.
10. Troubleshooting
Should the unit sustain severe damage and an increase in noise from the internal
parts is observed, discontinue use of the unit and contact a representative of
the Novaerus technical team for assistance. This product is not intended to be
repaired in the eld.
Should the unit not power on, or the fan stops working, check to ensure that the
fuse located on top of the unit is secured tightly in its socket. If, once the fuse is
replaced and the unit or fan does not turn on, immediately discontinue use.

and systems that are not life supporting
Recommended separation distances between portable and mobile RF
communication equipment and the Protect 900.
The Protect 900 is intended for use in an electromagnetic environment in
which radiated RF disturbances are controlled. The customer or the user of the
Protect 900 can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications equipment
(transmitters) and the Protect 900 as recommended below, according to the
maximum output power of the communications equipment.

the equation applicable to the frequency of the transmitter, where P is the
maximum output power rating of the transmitter in watts (w) according to the
transmitter manufacturer.
NOTE1 At 80 MHz and 800 MHz, the separation distance for the higher
frequency range applies.
NOTE2 These guidelines may not apply in all situations. Electromagnetic
propagation is affected by absorption and reection from structures, objects and
