1.1 General
The Welf-Air Compact range of generators has
been designed by HGI to perform exceptionally
well in the confi nes of a small cabin. New type
mounts are used in the set, so that vibration is
kept to a minimum, when placed on a cabin fl oor.
Two silencers, special sound insulation, water
cooled engines and careful canopy design keep
noise level to an absolute minimum.
The integral base mounted tank gives many
hours of continuous operation, is easy to refi ll and
has a low fuel shutdown to stop air entering the
fuel system. The access door is a lift-off type to
save space. The keyless stop/ start means no
lost keys.
The Welf-Air Compact has long service intervals
and its service items are on the outward facing
side, thus making servicing easy and economic.
Hot air exits the top quarter of the end panel
opposite the air inlet panel. The set is designed to
be pushed up to the right and against a cabin
wall, which should have a louvre panel cut into it.
Other louvres need to be made in the cabin to
allow cool air to enter the generator compartment.
The generators exhaust exits vertically. An
extension tube, brackets and heat wrap are
supplied. It is important that the heat wrap is
fi tted so that operatives do not burn themselves.
These instructions explain the installation of Welf-
Air Compact generators. Read completely before
installing.
The following notes are for the guidance of cabin
manufacturers and customers. Do not hesitate
to contact HGI Ltd for further advise and help.
The generators are supplied complete with:-
1. Approx 1 metre of fl exible exhaust pipe, two
exhaust pipe clamps and thermal insulation wrap.
2. A 63 Amp plug and lead to electrically connect to
the set.
3. Two
fl oor brackets that secure one side of the
generator.
4. Quick Start Guides with Manuals available for
download.
5. Laminated care sheets.
In essence, to install the generator:
1. Prepare the cabin, including air exits, louvres,
brackets and exhaust exit.
2. Fork truck the generator into position.
3. Push the set against the skid brackets and push
against the hot air outlet cut into the
4. cabin.
5. Bolt front skids down.
6. Clamp
fl exible to exhaust and cabin exhaust
outlet.
7. Connect cabin to the 63 Amp socket.
1.2 Ventilation
Adequate sized louvre panels should be built into the
cabin doors and cabin walls for generator ventilation
purposes.
NOTICE
Care must be taken to ensure that the machine
does not circulate its own exhaust fumes, the
machine must be able to take in cold air in order to
perform correctly.
1.3 Hot Air Outlet
A rectangular hole should be cut into the cabin wall
to allow the generator hot air to escape. The size
is 690mm wide by 973.5mm high and is positioned
112mm up from the top of the inside cabin fl oor (see
drawing PD901-908).
If at all possible, fi nish the interior of the cabins hot air
outlet with fl at fl ush metal so that the generators foam
seal has a suitable surface to seal against.
The outside fi nish is the responsibility of the cabin
manufacturer but should take into account:
• Weather
ingress
•
Animals, pests and vermin
•
Health & Safety considerations
