Installation

WARNING: Moving this machine on an incline may
cause instability and could result in the machine
tipping over. Equipment damage or bodily harm
could occur.
Place machine in a convenient location providing
ample support, drainage and room for maintenance.
These machines are intended for indoor use.
Machine must be stored indoors when not in use.
Location
The location should protect the machine from
damaging environmental conditions, such as wind, rain
and freezing.
1. The machine should be run on a level surface
where it is not readily influenced by outside
sources such as strong winds, freezing tempera-
tures, rain, etc. Consider accessibility for the
replacing of LP tanks, refilling of detergents, adjust-
ments and maintenance when selecting a location.
Normal precautions should be taken by the
operator to prevent excess moisture from reaching
electrical components.
2. It is recommended that a partition be made
between the wash area and the machine to
prevent direct spray from the spray gun to come in
contact with machine. Excess moisture reaching
the electrical controls will reduce the machine life
and may cause electrical shorts.
3. During installation, beware of poorly ventilated
locations or areas where exhaust fans may cause
an insufficient supply of oxygen. Sufficient combus-
tion can only be obtained when there is a sufficient
supply of oxygen available for the amount of fuel
being burned. If it is necessary to install in a poorly
ventilated area, outside fresh air may have to be
piped to the burner and a fan installed to bring air
into the room. Avoid small locations or areas near
exhaust fans.
Gas Codes
Confer with local gas company and with proper
municipal officials regarding any specific code or regu-
lations governing the installation. The installation must
conform to local codes.
The gas pressure coming out of the regulator and going
to the burner ring has been factory set for elevations of
0 to 2000 ft. Altitudes greater than 2000 ft will require
adjustments to the gas manifold pressures.
Landa VHP 2-1500 / 3-2000 Operator's Manual 8.913-949.0 - T
Consult your local service dealer for high altitude
adjustments. In Canada, certification for installation at
altitudes over 4500 feet above sea level is the jurisdic-
tion of local authorities. You should not readjust the
burner ring gas pressure. If you replace your gas valve,
you will need to adjust the new valve. Refer to your
machine's specification plate for the correct pressure
setting. Follow the installation and adjustment instruc-
tions provided with your replacement valve.
NOTE: Air for combustion and ventilation along with
exhaust flue sizing must conform to methods outlined
in current American Standard (ANSI-Z223.1) National
Fuel Gas Code or National Standard of Canada CSA-
149.1 and CSA-149.2 "Installation Code for Gas
Burning Appliances".
Electrical
This machine, when installed, must be electrically
grounded in accordance to local codes. Check for
proper power supply using a volt meter. The VHP2-
15021D requires a 20 amp receptacle to comply with
UL 1776 certification standards.
Venting
Regulations or ventilation concerns may call for a
chimney or furnace pipe.When venting, if the machine
is to be in an enclosed area with a chimney on it, be
sure the chimney is the same size as the stack on the
machine. Poor draft will cause machine to soot and not
operate efficiently. When placing for installation, keep in
mind that the pressure washer should be positioned in
such a manner that the stack will be as straight as
possible and protrude through the roof of the building at
a proper location and at sufficient height to eliminate
downdraft. The chimney of gas fired machines should
be installed with a down draft diverter.
Draft Diverter
A draft diverter should be installed above the heating
coil. The diverter serves to sever the chimney effect
created in all sections of furnace pipe positioned below
to enhance the draft through the burner. It also helps
prevent freezing of the coil due to wind chill factors.
NOTE: The draft diverter is
not standard on VHP
machines.
