Installation Instructions - Hotsy 555HE Operating Instructions And Parts Manual

Getting Started
IMPORTANT: Proper initial installation of equipment
will assure more satisfactory performance, longer
service life and lower maintenance cost.
WARNING: If connection is made to a potable wa-
ter system, the system shall be protected against
backflow.
AVERTISSEMENT: Si une connexion est établie avec
un réseau d'eau potable, le réseau doit être protégé
contre le retour d'eau.
ADVERTENCIA: Si se realiza una conexión a un
sistema de agua potable, el sistema debe estar pro-
tegido contra el reflujo.
The pressure washer should be run on a level surface
where it is not readily influenced by outside sources
such as strong winds, freezing temperatures, rain, etc.
The pressure washer should be located to assure easy
access for filling of fluids, adjustments and maintenance.
Normal precautions should be taken by the operator to
prevent moisture from reaching the pressure washer. It
is recommended that a partition be made between the
wash area and the pressure washer to prevent direct
spray from the wand coming in contact with the pressure
washer. Moisture reaching the equipment will reduce the
pressure washer's life. All installations should comply with
the local codes covering such installations.
Venting
CAUTION: All venting must be in accordance with ap-
plicable federal and state laws, and local ordinances.
Consult local heating contractors.
ATTENTION: Toute la ventilation doit être conforme
aux lois fédérales et de l'État ou de la province, et
aux réglementations locales applicables. Consulter
des entrepreneurs en systèmes de chauffage locaux.
PRECAUCIÓN: Toda la ventilación debe ser de acu-
erdo con las leyes federales y estatales aplicables
y las ordenanzas locales. Consulte a contratistas
locales de calefacción.
If the pressure washer is to be used in an enclosed area, a
flue must be installed to vent burner exhaust to the outside
atmosphere. Exhaust gases should not be vented into a
wall, a ceiling, or a concealed space of a building. Be sure
the flue is the same size as the burner exhaust vent on
the pressure washer. See Component Identification for
location. Poor draft will cause the pressure washer to soot
and not operate properly. When selecting the location for
installation, beware of poorly ventilated locations or areas
where exhaust fans may cause an insufficient supply of
oxygen. Proper combustion 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
the machine in a poorly ventilated area, outside fresh air

may have to be piped to the burner and a fan installed to
bring sufficient air into the machine. Locate the pressure
washer so that the flue will be as straight as possible and
protrude through the roof at a proper height and location
to provide adequate draft. This oil fired pressure washer
must have a draft regulator installed in the flue (available
from most heating contractors). A draft regulator will permit
proper upward flow of exhaust flue gases.
NOTE: This product is labeled of outdoor use only and
should be operated outdoors. It is not recommended to
operate indoors. If under certain conditions that make it
impossible to operate outdoors you can operate indoor
using a hood vent or venting. Venting can cause restriction
of air flow through the combustion chamber causing
excessive soot. Use a larger vent size then the exhaust
stack to prevent restriction and contact the local servicing
dealer to adjust the air mixture after installation of vent.
Burner Air Adjustment
The oil burner on this machine is preset for operation at
altitudes below 500 feet. If operated at higher altitudes,
it may be necessary to adjust the air band for a #1 or
#2 smoke spot on the Bacharach scale.
To adjust, start machine and turn burner ON. Loosen
two locking screws found on the air band and close air
band until black smoke appears from burner exhaust
vent. Note air band position. Next, slowly open the air
band until white smoke just starts to appear. Turn air
band halfway back to the previously noted position.
Tighten locking screws.
For higher altitudes, the air band opening may need
to be increased; for lower altitude, the air band may
need to be decreased.
For higher humidity, the air band opening may need to
be increased; for lower relative humidity, the air band
may need to be decreased.
For higher ambient temperatures the air band opening
may need to be increased; for lower ambient tempera-
tures, the air band opening may need to be decreased.
Adjust to your operating location's environment as
needed for best smoke spot and performance compli-
ant with local, state, and federal regulations.
