Precautions
ATTENTION: Please read all of these instructions before you operate your
Dipper for the first time. Save these instructions for further reference.
For your own protection and prolonged operation of your Dipper, be sure to read
the following precautions carefully before use.
On Safety
Check that the operating voltage of
your unit is identical with the voltage
of your local power supply. If voltage
adaptation is required, consult with
qualified an electrician.
Should liquid or solid objects fall into
the unit, unplug and have it checked by
qualified personnel before operating it
further.
To disconnect the cord, pull it out by the
plug. Never pull the cord itself.
The power supply should be near the
unit and easily accessible.
The unit is not disconnected from
the AC power source as long as it is
connected to the wall outlet, even if the
unit has been turned off.
Do not place your hand or other objects
near the trapdoor during operation.
The Skyhook Projector Mount must be
used for installation with the Dipper.
On Cleaning
To keep the unit looking new and clean
a dust cover is supplied. If cleaning is
necessary use a soft cloth and mild
detergent solution. Never use strong
solvents, such as thinners, benzene, or
abrasive cleaners.
Never operate the Dipper while the projector is still powered!

Make consideration of the maintenance of the Dipper when installing it. Wherever
possible, allow access to the ceiling cavity other than through the Dipper’s hole
- so that you can access the projector if the power supply fails!

Mechanical Installation
The first crucial step, like any projector installation, is to determine where to put
the Dipper in the ceiling. The Dipper should be installed so that the projector
lens is centered horizontally to the screen, and the distance from the screen
depends on the projector’s throw distance.
Work out the maximum and minimum throw distances for the projector and
place the Dipper somewhere in between. It is better for the projector to be
closer to the screen, but don’t place it at an extreme—leave yourself some
room to adjust the zoom in either direction.

Note: when aligning the Dipper
make sure that the projector
lens is centered on the screen,
which is not necessarily the
projector center.

Installation
The Dipper comes with a 12mm undercoated MDF face panel and an aluminium
ceiling trim.
We recommend that you paint this panel before fixing the Dipper in the ceiling.
In the case of a non-plasterboard ceiling, you may choose to fabricate your own
ceiling panel (eg from the same timber/material as the ceiling itself) to match.
We recommend you leave a 2mm gap around all edges of the Dipper’s face
panel.
Supplied is a plastic trim that you may use to finish off the edge of the hole. The
cutout dimensions given below assume that you will use this ceiling trim.

Ceiling Fastening - Suspended Ceiling
For suspended ceilings you can suspend the Dipper itself through the four
mounting holes using threaded rod.
You can use the nuts to adjust the height of the Dipper once
installed, so you can get it exactly flush with the ceiling.

Installation
Ceiling Fastening - Trussed Ceiling
For some ceilings, you will need to construct a support structure for the Dipper
to rest in - this can be as simple as two appropriately spaced bearers at the
right height. See the previous pages for the relevant dimensions.
Allow yourself some way to easily adjust the height of the Dipper once
installed, so you can get it exactly flush with the ceiling.

Mechanical
Installation
Once the Dipper frame is install you should attached the face panel.
We recomend you paint the face panel to match the room before installing it.
1. Insert 4 x countersunk bolts, washers and springs as shown through face panel
from the underside.
2. Adjust the level so that it is exactly flush with the underside of the ceiling.
3. Once full adjusted, cover holes with stick pads. (for more information, refer to

The Dipper is supplied with a unique control unit that can be adapted to just about
any installation requirement.
It operates via dry contacts, but can be easily upgraded to a 12V trigger, Infra Red,
Radio Frequency remote control, or even RS232.
A Maintained, Single Pull, Single Throw Switch (a normal light switch) comes
supplied as standard. or alternatively you can use a single relay. Open circuit is
up, close circuit is down.
You do not need to be a qualified electrician to wire the Dipper, as all circuiting is
24V, however Herma will not accept responsibility for damage incurred by faulty
or incorrect wiring.
The power supply and motor are pre-wired, so all you need to do is attach relay
or motor cable and switch as shown in the following diagram. The switch needs
to be wired into the “Switch Up” and “Common” terminals.
