Unit installation

4
Foundation, Support & Isolation: Suitable structural support and vibration isolation must be provided as indicated in
these instructions. Failure to do so may result in injury to the operator or damage to the equipment and/or building.
Discard Intrusions: The units are not designed to bear additional loads or stresses from adjacent equipment,
pipework or structures. Additional components must not be mounted on these units. Any such external loads may
overload the units and cause structural failure resulting in injury to the operator or damage to equipment.
Restricted Access to Equipment: This equipment is a complex engineering product and 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 necessary to ensure that access to the unit is restricted to suitably qualified
personnel who are familiar with the potential hazards and precautions required for safe operation and maintenance of
this equipment.
High Pressure & Temperature System: The units contain refrigerant vapor and liquid under high pressure and
temperature and release of which can be dangerous and cause injury. The user should ensure that care is taken
during installation, operation and maintenance to avoid damage to the pressure system. Access to component parts
of the pressure system shall be restricted to suitably trained and qualified personnel only.
Electrical: The units must be grounded. No installation or maintenance work should be attempted on the units 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 personnel. No attempt should be made to gain access to the control panel or electrical
enclosures during normal operation of the units.
Rotating Parts: Fan guards must remain fixed in their position at all times and if any need arises to remove them for
inspection or maintenance, then remove the guards only after the power supply has been isolated.
Sharp Edges: The fins on the air-cooled condenser coils have sharp metal edges. Sufficient care should be taken
when working in contact with the coils to avoid the risk of abrasions and lacerations. The use of gloves is
recommended.
Refrigerant and Compressor Oil: Refrigerants and oils used in the units are non-flammable and non-corrosive and
do not pose a serious hazard. However, use of safety shoes, gloves and safety goggles is strongly recommended
when working on these units. Avoid direct skin or eye contact with the refrigerant as it results in frostbite injury.
Further, attention should be given to good ventilation when working in confined or enclosed spaces, as the build-up of
refrigerant vapor, from a leak for example, does pose a risk of asphyxiation.
For more detailed information on safety precautions for use of refrigerant, please refer Material Safety Data Sheet
given in the Appendix of this manual.
High Temperature and Pressure Cleaning: High temperature and pressure cleaning methods like hot water or
steam cleaning should not be used on any part of the pressure system as this will cause excessive pressure in the
system and trigger operation of the pressure relief device(s). Detergents and solvents which may cause corrosion
should also be avoided.
The following symbols are used in this manual to alert the reader:
WARNING denotes a potentially hazardous situation which, if not avoided,
could result in serious injury or death.
CAUTION denotes a hazard which could lead to damage to the unit and damage
to other equipment.
