Greenwood Airvac P1 User manual

P1/PD
Installation Instructions
Please read all instructions before commencing
installation.
1. Observe appropriate safety precautions if working off
steps or ladders.
2. Wear eye protection when breaking out wall or
ceiling materials etc.
3. Siting notes:
To avoid short circuiting of air flow, fans should be
sited at a high level and as far away as possible from
the main source of replacement air. The fan should
not be sited where it would be subject to a direct
source of heat in excess of 40oC. If installed in a
room containing a fuel burning appliance of a non-
balance flue design, it is the responsibility of the
installer to ensure that sufficient replacement air is
provided to prevent products of combustion from
being drawn down the flue when the fan is operating
and that the air intake is located at least 500mm
away from the flue. Exhaust air from the fan must not
be allowed to discharge into a flue used for extracting
fumes from an appliance other than those powered
by electricity. Regulations regarding the discharge of
exhaust air must be observed.
4. When installing wall mounted fans, cable run, or
switches, ensure that there are no buried cables
or pipes in the way. Greenwood Airvac recommends
that this fan is mounted 1.8m above floor level.
5. This appliance can be used by children aged from 8
years and above and persons with reduced physical,
sensory or mental capabilities or lack of experience
and knowledge if they have been given supervision
or instruction concerning use of the appliance in
a safe way and understand the hazards involved.
Children shall not play with the appliance. Cleaning
and user maintenance shall not be made by children
without supervision.
Note:
If no TIMER is tted or likely to be tted to P1 or PD fans,

3. Drill and plug 4 screw holes suitable for No.8 screws.
4. Fit adhesive foam plastic strip around exhaust spigot (not
required if exiduct hose-clip is used).
5. Fit adhesive foam plastic strip around secondary inlet
spigot if required.
6. Fit rubber sealing strip around base plate of unit.
Ensuring that is has shortest side outward. (P1 only).
7. Fit anti-back-draught shutter into exhaust spigot ensuring
hinge is to the top. (P1 only).
8. Fit base plate to wall using No.8 screws.
Note: PD only to t, motor chassis may be unscrewed
and unplugged from the base plate before xing base
plate to the wall.
9. Fit timer if required.
(See separate installation instructions).
10. Wire fan as required. (See wiring diagram).
11. If cable knock outs in Terminal Block Cover are removed,
ensure that the edges of the knock outs are dressed so
that the external cable insulation is not damaged by any
sharp edges.
12. Replace cover, ensuring printed circuit tongue locates in
the electrical connector and is fully home.
