TRUCLIMATE 500 INSTALLATION GUIDE
General Installation Information
NOTICE: Do not store or install units in corrosive environments
or in locations subject to temperature or humidity extremes.
Corrosive conditions and high temperature or humidity can
significantly reduce performance, reliability, and service life.
NOTICE: A minimum of 24 in. clearance should be allowed
for access to front access panel.
NOTICE: To avoid equipment damage, DO NOT use
these units as a source of heating or cooling during the
construction process. The mechanical components and
filters can quickly become clogged with construction dirt
and debris, which may cause system damage and void
product warranty.
For the Installer
If you are NOT sure how to install or operate the unit, contact your
dealer.
Installing and servicing air conditioning and heating equipment
can be hazardous due to system pressure and electrical compo-
nents. Only trained and qualified service personnel should install,
repair or service heating and air conditioning equipment. When
working on heating and air conditioning equipment, observe pre-
cautions in the literature, tags and labels attached to the unit and
other safety precautions that may apply.
This manual contains specific information about the required qual-
ification of the working personnel for maintenance, service and
repair operations. Every working procedure that affects safety
means shall only be carried out by competent persons.
Examples for such working procedures are:
•
breaking into the refrigerating circuit;
•
opening of sealed components or ventilated enclosures.
Follow all safety codes. Wear safety glasses and work gloves. Use
quenching cloth for brazing operations. Have fire extinguisher
available for all brazing operations. Follow all procedures to re-
main in compliance with national gas regulations.
Prior to beginning work on systems containing FLAMMABLE
REFRIGERANTS, safety checks are necessary to ensure that the
risk of ignition is minimized. Work shall be undertaken under a
controlled procedure so as to minimise the risk of a flammable
gas or vapor being present while the work is being performed. All
maintenance staff and others working in the local area shall be
instructed on the nature of work being carried out. Work in con-
fined spaces shall be avoided.
The area shall be checked with an appropriate refrigerant detec-
tor prior to and during work, to ensure the technician is aware
of potentially toxic or flammable atmospheres. Ensure that the
leak detection equipment being used is suitable for use with all
applicable refrigerants, i.e. non-sparking, adequately sealed or
intrinsically safe.
If any hot work is to be conducted on the refrigerating equipment
or any associated parts, appropriate fire extinguishing equipment
shall be available to hand. Have a dry powder or CO2 fire extin-
guisher adjacent to the charging area.
No person carrying out work in relation to a REFRIGERATING
SYSTEM which involves exposing any pipe work shall use any
sources of ignition in such a manner that it may lead to the risk of
fire or explosion. All possible ignition sources, including ciga-
rette smoking, should be kept sufficiently far away from the site
of installation, repairing, removing and disposal, during which
refrigerant can possibly be released to the surrounding space.
Prior to work taking place, the area around the equipment is to
be surveyed to make sure that there are no flammable hazards or
ignition risks. “No Smoking” signs shall be displayed.
Where electrical components are being changed, they shall be
fit for the purpose and to the correct specification. At all times
the manufacturer’s maintenance and service guidelines shall be
followed. If in doubt, consult the manufacturer’s technical depart-
ment for assistance.
The following checks shall be applied to installations using FLAM-
MABLE REFRIGERANTS:
•
the actual REFRIGERANT CHARGE is in accordance with
the room size within which the refrigerant containing parts
are installed;
•
the ventilation machinery and outlets are operating ad-
equately and are not obstructed;
•
if an indirect refrigerating circuit is being used, the second-
ary circuit shall be checked for the presence of refrigerant;
•
marking to the equipment continues to be visible and leg-
ible. Markings and signs that are illegible shall be corrected;
•
refrigerating pipe or components are installed in a position
where they are unlikely to be exposed to any substance
which may corrode refrigerant containing components,
unless the components are constructed of materials which
are inherently resistant to being corroded or are suitably
protected against being so corroded.
Instructions for Equipment Using R-454B
Refrigerant
•
Do NOT pierce or burn
•
Do NOT use means to accelerate the defrosting process or to
clean the equipment, other than those recommended by the
manufacturer
•
Be aware that refrigerants may not contain an odor
WARNING
•
The Appliance should be stored so as to prevent mechanical
damage and in a room without continuously operating
ignition sources (example: open flames, an operating gas
appliance or an operating electric heater)
