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 specified
in these instructions. Any use of the equipment other
than its intended use, or operation of the equipment
contrary 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
parameters specified in this manual.
Structural Support
Structural support of the unit must be provided as
indicated 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.
Additional 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.
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 damage
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 earthed. No installation or maintenance
work should be attempted on the electrical equipment
without first switching power OFF, isolating and locking-
off the power supply. Servicing and maintenance on live
equipment must only be performed by suitably trained
and qualified personnel. No attempt should be made to
gain access to 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 removed,
alternative safety measures must be taken to protect
against the risk of injury from rotating fans.
