IMPORTANT: Safety Advisories
•All installation and rigging work done must where applicable be designed and built in
accordance with norms and standards of the local authority having jurisdiction of the
installation site. It is the responsibility of the installer to obtain such approvals as may be
required to achieve full compliance.
•All electrical work must be carried out by a suitably licensed electrical contractor in full
compliance with local electrical standards.
•Lifting: some enclosures and the equipment inside them may be heavy. Use properly
rated lifting equipment where appropriate and never attempt to carry out work with
fewer than the number of workers needed to lift safely.
•It is the responsibility of the installer to ensure that all local building, safety and electrical
codes are strictly adhered to in the installation of this enclosure. Tempest Lighting, Inc.,
its employees and agents are in no way responsible for damage arising from failure to
follow either the instructions in this manual or building, safety and electrical codes
prevailing at the installation location.
•Do not attempt to install or operate the enclosure before fully reading and understanding
this manual
•Never allow anyone who has not read this manual to open the enclosure or perform
maintenance on the projector within.
•Never leave the enclosure unattended when open.
•Always make sure all bolts and latches are tight and safety locks are in place after
performing any form of maintenance on the unit.
•Do not open any electrical boxes until power has been shut off to all supply lines to the
enclosure (including the one powering the projector).
•Do not open the enclosure in wet weather.

Access Clearance
Observe these minimum access clearances shown around your
enclosure, for comfortable access.
Illustration shows projector slide option, but sides should be kept
clear for both slide and fixed projector mounting versions.
Mounting Hardware Options
IMPORTANT SAFETY NOTICE
Installer must ensure that all mounting points are secure and
conform to local safety regulations. Tempest Lighting Inc.
accepts no responsibility for damage or injury arising from
inappropriate or unsafe installation.
Mounting Bolts
•Each Enclosure must be mounted with at least FOUR M10
bolts (supplied).
•All mountings must be made using the M10 threaded holes
on the top of the enclosure.
•Use a 6mm hex key to secure the M10 socket cap screws
provided.
•Tempest recommends the use of stainless steel mounting
hardware.
Mounting Options –Unistrut Kit
If mounting positions for the corner bolts are not convenient,
use the Unistrut Kit (52.UR.xxx) to add two Unistrut rails and
Unistrut spring nuts to the top of the enclosure.
Using standard Unistrut hardware, the enclosure may now be
attached at any point along the Unistrut rails.

Installing Duct Hoses and Fans
The excellent noise attenuation levels you can achieve using
Whispr enclosures depend on the acoustic separation of the
audience from the enclosure’s exhaust fan.
Tempest recommends locating the exhaust fan in a separate
location, ideally on the other side of a wall from the audience
space. Where this is not possible, it will be necessary to install
acoustic insulation between the exhaust fan and the audience
space.
Tempest supplies two flexible padded hoses with each Whispr
enclosure:
8m (25’) Exhaust hose, with fan cable pre-installed
4m (12’) Inlet hose
Whispr 53.050-100 are supplied with 8”/200mm Hose
Whispr 150 is supplied with 10”/250mm Hose
(dimension is internal –add 2”/50mm for external diameter)
Installing Flexible Hoses
It is important to stretch the hoses during installation to
minimize the turbulence caused by the internal wall
corrugations. They will relax slightly, but this will greatly
improve airflow and minimize noise.
Fix the hoses to the enclosure duct hose rings using the hose
clamps supplied:
Exhaust Fan Kit in
adjoining space.
May connect to

Whispr G4 User Manual 12
Whispr Fan Kit
Your Whispr enclosure is supplied with a fan assembly to be
mounted at a remote location (described above).
1. Mount the fan kit either on the side of a building
return air duct, or blowing into an open space such as
a roof void.
2. Connect the enclosure exhaust hose adapter to the
fan kit using the supplied hose clamp
3. Trim to length by cutting the enclosure end of the
hose and trimming the fan cable to suit.
4. Connect the enclosure end to the fan terminals in the
Whispr wiring compartment (see below)
For mounting locations, see drawing on next page.

Wiring and Fan Speed Setup
SAFETY NOTICE
All power wiring must be performed by a competent electrician, appropriately licensed in the jurisdiction where the installation
takes place. All electrical work must be done in full compliance with all electrical and safety norms applicable to the installation
site. Isolate all power feeds before opening the enclosure.
Tempest Lighting, Inc., its employees and agents will not be held responsible for damage or injury caused by disregarding this
notice.
Electrical Standards
Important:
Enclosure model numbers including .US are for use in countries using US and Japanese style electrical systems:
100-125VAC 50/60Hz (208V to special order)
Enclosure model numbers including .IN are for use in countries using European style electrical systems:
220-250VAC 50/60Hz
Wiring Access
Locate the two Conduit entry holes on the top and back panels
of the enclosure. Choose either the top or back conduit entries,
to suit local conditions.
Conduit openings accept PG21 (International) and 3/4” NPT
(North America) conduit fittings.
Use permanent or flexible conduit to connect power and signal
cables to your Whispr enclosure.
ALWAYS RUN POWER AND SIGNAL CABLES IN SEPARATE
CONDUITS.
Use a screwdriver to pry open the desired conduit knockouts:
Remove the wiring cover plate.
NOTE: Layout of Whispr models may differ slightly

Capacitor Wiring
Two capacitors are supplied with each enclosure. The capacitors provide a simple means to slow down the remote fan, and also
reduce fan noise.
Capacitor values vary depending on enclosure model and supply voltage. The following diagram is provided for information only –
no user wiring is required:
Adjusting the Thermostat
When your installation is complete,
1) Set the thermostat temperature to approximately 90°F, or
30°C, using the blue temperature adjustment dial
2) Adjust so that the fan does not run when the projector lamp is
off, but starts soon after the lamp turns on

Projector and Aux Power
Connect the projector and any additional equipment to
be included in the enclosure to the two IEC C13 outlets
on the side of the wiring box.
Two rewireable C14 plugs are included.
The C13/14 connectors are rated as follows:
100-120VAC 15 Amp
200-250VAC 10 Amp
Whispr Operation
Whispr operation is automatic, controlled by the
thermostat described above.

Mounting the Projector
Projector Mount –Fixed or Slide?
Whispr enclosures may be specified with either fixed or
sliding projector mounts.
•Fixed mounts clamp the projector firmly in
place, with pan, tilt, and roll adjustment
achieved using the projector’s feet. An
economical choice for laser projectors with
infrequent service access needs.
•The Slide Mount option is a projector tray,
with clamps to hold the projector firmly in
place. Easier install, and good for access to
lamp-based projectors needing more frequent
service access.
•Slide Mounts may be supplied to slide out of
either right or left side (left slide shown here).
•Now that most projectors have the same
vertical lens shift in both directions, tabletop
(feet down) installation is standard.
•For Ceiling-style (feet-up) installation, see the
52.FU Kit below.

Whispr G4 User Manual 19
Projector Mount –Feet-up Kit
The feet-up kit (52.FU) may be used in fixed or slide
mounting enclosures.
The kit comprises two platforms, adjustable in height to 25,
50 or 75mm (1, 2 or 3in). This allows for mounting different
sized projectors as high as possible in the enclosure, for
maximum downwards lens shift, without clipping on the edge
of the port glass.
Set the platforms on the projector bridges/tray, and lay the
projector, feet up, on the padded bearing surfaces.
Align the projector and clamp in place with the projector
clamps.
The Feet-up kit comes with two sets of legs, for 50mm and
75mm heights.
For 25mm height, discard the legs.

either fixed or slide mount versions.
In either case the projector mounts on two bars, using
screws and washers provided.
The projector bars mount to a special box frame mount,
