General Safety Precautions
To Prevent Overheating
The recommended clearances and other precautions given in these instructions must be
observed to prevent overheating. In addition, units should not be positioned where they
are likely to become covered by curtains/fabrics or thermal insulation materials in a roof
space or similar building void. The unit should not be left resting on a carpet.
Other Precautions
These appliances are not waterproof. They are for indoor use only and must not be positioned where they could be exposed to dripping or splashing water. Objects containing
liquids should not be placed on or near the appliance. To prevent risk of fire, keep the
unit and attached wiring well away from naked flames.
Fitted Mains Plug
These appliances are supplied with a standard fixed plug already fitted. If this is not
suitable, refer to the instructions below. If you need to change the fuse in this plug,
a 3Amp fuse to BS1362 carrying the ASTA or BSI approved mark must be used.
Always re-fit the plastic fuse carrier when replacing the fuse.
Changing the Plug
If the fitted mains plug is not suitable for the socket outlet in use, it should be cut off
and an appropriate new plug fitted. Any instruction supplied with the plug should be
followed. The Brown wire must be connected to the live (L) terminal of the plug and the
Blue wire to the neutral (N) terminal. Neither wire should be connected to the earth (E)
terminal of a 3-pin plug (this appliance does not require an earth connection to the 3
pin plug). Ensure that the cord grip in the plug is correctly used and clamps the sheath
of the cord firmly.
Fuse Rating: If the new plug is a fused type, the fuse fitted should be rated at no more
than 3 Amp. Caution: The old plug should be disposed of promptly since it would be
dangerous if plugged into a live socket.

Installation Instructions
Introduction
These fully screened general-purpose 4, and
8 way amplifiers are ideal for distributing TV,
FM, DAB radio, Satellite and CCTV signals.
There are separate inputs for each of these
signal sources.
The HDU641 and HDU681 have a switch
which should be set to ‘SAT’ if a satellite receiver
is included in the system, or switched to ‘UHF
& CCTV’ if only using the UHF/CCTV inputs
(this links the downlink and uplink).
All units are suitable for handling digital
terrestrial TV (DTT /Freeview) signals in
addition to analogue signals. Distribution
of DTT signals requires careful attention
to signal levels for satisfactory results.
Applications
All antenna cables should be cabled direct to the loft (using PF100 or similar digital cable) where
they are individually connected to the Home Distribution Unit. The unit combines the FM, DAB, UHF
TV, CCTV, LNB 1 and LNB 2 signals together and distributes them via the down link to the Master
point. LNB 1 has a dedicated input and output.
1. Satellite - The wiring diagram on page 2 shows how to make connections. The cable from the
DOWNLINK OUT on the HDU feeds into the TRIPLEXED INPUT on the rear of the main outlet plate, if
you are fitting SKY+™ or Sky HD™ a second connection from LNB 1 OUT is fed down to the Master
point on a separate cable, straight through to the SAT 2 INPUT on the back of a Quad outlet plate
(PSW351T or PSW241) or to a separate single F outlet (PSW111) if preferred.
To view satellite and TV signals from other outlets a return feed needs to be run from the RF2 output
of the digital satellite receiver to the UPLINK IN socket of your HDU. This can be made via a
combination socket that has an integrated coax RETURN socket (PSW351T or PSW242T) or by fitting
a separate single coax RETURN socket (PSW111).
There are several different options for outlet plates at your Master point - see the table on page 2
and choose an outlet or a combination of outlets according to your requirements and according to
what outlets are already in place.
2. Radio - the FM and DAB signals are split internally to feed both the Downlink and the remote
rooms. This does not apply to the UHF TV signal, this must come from the Uplink.
3. The CCTV input needs to be modulated. If CCTV is not required terminate input with plug supplied.
Note: All HDU distribution units have a 6mm
These products must use non-isolated fully screened outlet plates (such as the PSW range).
Installation
Important note: attention is drawn to the General Safety Precautions Panel on page 4 which
contains advice referring to safe installation and operation of these products.
