Installation Guide
1.0 Installation
Installation of the generator is to be made by qualified
personnel in accordance with the appropriate
regulations e.g., Electricity Safety, Quality and
Continuity Regulations 2002 (S.I. 2002/2665), and the
following Electrical Safety regulations:
• I.E.E Regulations 17th Edition (BS 7671:2008)
• Health and Safety Executive Publications GS27
• Protection Against Electric Shock
• Health and Safety Executive Publications GS24
• Electricity On Construction Sites
• Health and Safety Executive Publications PM53
• Emergency Private Generation
1.1 General
The Welf-Air Compact range of generators has
been designed by HGI to perform exceptionally
well in the confines 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 floor.
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 refill 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
fitted 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 flexible 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 floor 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 flexible 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 floor (see
drawing PD901-908).
If at all possible, finish the interior of the cabins hot air
outlet with flat flush metal so that the generators foam
seal has a suitable surface to seal against.
The outside finish is the responsibility of the cabin
manufacturer but should take into account:
• Weather ingress
• Animals, pests and vermin
• Health & Safety considerations

498-1075 2 Welf-Air 10kVA Cube
Installation Guide
• Security and vandalism
Allow a 210mm clearance to access the electrical
output socket at the front of the generator.
1.4 Positioning Generator
When you look into the cabins generator compart-
ment, the generator is positioned up against
the right hand cabin wall. The hot air escape
should be cut into the right hand wall.
1.5 Fixing Skids
The skids are fitted flush front and back to the
generator and at 170mm from the sides of the
generator.
The skids are 200mm wide by 70mm high (see
drawing WG-WA100H).
1.6 Connecting Hot Air Outlet
The hot air outlet is on the right hand side of the set
which should be pushed up to the right hand cabin
wall, to within 25mm of the cabin wall. The foam seal
(supplied fitted to the generator) around the hot air
exit will squash and act as an air seal. It does not
need to be perfectly air tight (see drawing PD901-
908)
Alternative arrangements for hot air outlet using
plenum connection to exit louvres can be provided by
HGI for installation into buildings.
1.7 Fixing Down
Fixing down is via the bolt holes in the skid pods on
the base of the generator. The fixing down holes
are located 57.5mm from front and back and are are
675mm apart on the same skid and 560mm distant
from the corresponding hole on the second skid. The
See drawings WG-WA100H.
The generator, when being fixed down using the
standard foam seal arrangement, will have the right
hand side fixing down hole approx 300mm from the
wall (see PD901-908).
The type of fixing will depend on the floor type,
thickness of floor material etc.
1.8 Cabin’s Exhaust Outlet
The exhaust pipe comes out of the top of the Welf-
Air generator’s canopy and is then turned through 90
degrees so that it comes out of the side wall of the
cabin. This is done so there are no problems with
water entry through the roof or stacking the cabins on
top of each other. The welded exit pipe can be cut
at an angle outside to stop rain getting in.
1.9 Connecting the Exhaust
Using the flexible pipe and clamps supplied,
connect the flexible pipe to the generator exhaust
stack and to the cabins exhaust outlet (see drawing
PD901-908).
Finally use the thermal insulating bandage supplied
to wrap around the flexible exhaust pipe to insulate
it and protect people from touching the hot pipe. Use
steel wire ties or similar at each end to prevent the
bandage from becoming unwrapped.
NOTICE
Care must be taken to make a gas tight seal
when connecting the exhaust.
1.10 Electrical Connection
A 63 amp BS4343 socket is fitted on the generator
adjacent to the fuel fill and below the socket panel.
This single socket supplies all the generators power
for the cabin. The additional sockets are for auxiliary
use for lights, tools or other cabins.
1.11 Clearance Space
The generators need to occupy a clear space within
the cabin compartment for ventilation and to allow
access for refuelling and service.
Cables, water pipes, pumps, tanks, waste and other
items should be located away from the generator.
2.0 Contact
If you are in any doubt or have any concerns about
the safe installation of the generator then please
consult with your service depot or contact HGI:
