ABOUT THIS MANUAL
The contents of this manual include suggested best
working practices and procedures. These are issued for
guidance only, and they do not take precedence over
the above-stated individual responsibility and/or local
safety regulations.
This manual, and any other document supplied with the
unit, are the property of YORK, which reserves all rights.
They may not be reproduced, in whole or in part, with-
out prior written authorization from an authorized YORK
representative.
MISUSE OF EQUIPMENT
Suitability for Application
The unit is intended for cooling water or glycol solutions
and is not suitable for purposes other than those speci-
fied in these instructions. Any use of the equipment other
than its intended use, or operation of the equipment con-
trary to the relevant procedures, may result in injury to
the operator or damage to the equipment.
The unit must not be operated outside the design pa-
rameters specified in this manual.
Structural Support
Structural support of the unit must be provided as indi-
cated in these instructions. Failure to provide proper
support may result in injury to the operator, or damage
to the equipment and/or building.
Mechanical Strength
The unit is not designed to withstand loads or stresses
from adjacent equipment, pipework or structures. Addi-
tional components must not be mounted on the unit. Any
such extraneous loads may cause structural failure and
may result in injury to the operator, or damage to the
equipment.
General Access
There are a number of areas and features which may
be a hazard and potentially cause injury when working
on the unit unless suitable safety precautions are taken.
It is important to ensure access to the unit is restricted
to suitably qualified persons who are familiar with the
potential hazards and precautions necessary for safe
operation and maintenance of equipment containing high
temperatures, pressures and voltages.
YORK INTERNATIONAL
Pressure Systems
The unit contains refrigerant vapor and liquid under
pressure, release of which can be a danger and cause
injury. The user should ensure that care is taken during
installation, operation and maintenance to avoid dam-
age to the pressure system. No attempt should be made
to gain access to the component parts of the pressure
system other than by suitably trained and qualified
personnel.
Electrical
The unit must be grounded. No installation or mainte-
nance work should be attempted on the electrical equip-
ment without first switching OFF, isolating and locking
off the power supply. Work on live equipment must only
be carried out by suitably trained and qualified person-
nel. No attempt should be made to gain access inside
the control panel or electrical enclosures during normal
operation of the unit.
Rotating Parts
Fan guards must be fitted at all times and not removed
unless the power supply has been isolated. If ductwork
is to be fitted, requiring the wire fan guards to be re-
moved, alternative safety measures must be taken to
protect against the risk of injury from rotating fans.
Sharp Edges
The fins on the air-cooled condenser coils have sharp
metal edges. Reasonable care should be taken when
working in contact with the coils to avoid the risk of
minor abrasions and lacerations. The use of gloves is
recommended.
Refrigerants and Oils
Refrigerants and oils used in the unit are generally non-
toxic, non-flammable and non-corrosive, and pose no
special safety hazards. Use of gloves and safety glasses
are, however, recommended when working on the unit.
The build-up of refrigerant vapor, from a leak for ex-
ample, does pose a risk of asphyxiation in confined or
enclosed spaces, and attention should be given to good
ventilation. For more comprehensive information on
safety precautions for use of refrigerants and oils, refer
to the Materials Safety Data tables provided on pages
11 through 14.
