3. Safety Guidelines
3.1General Safety Concerns
Before proceeding to install, commission, or operate the equipment described in the instruction manual we would like to
alert you to the dangerous potential hazards that would be present if safety practices were not performed in accordance
with the local standards and governing bodies’ regulations.
-Injury would occur to the operational staff of the equipment through misuse, electric shock, rotating equipment hazards
and lack of cleanliness.
To be able to achieve the aim, of “accidents can be avoided” it must be ensured that the equipment is installed correctly,
regularly maintained and operators of the equipment are made aware of the potential hazards associated with the
particular equipment.
We would like to inform our valuable customers of the safety guide lines when using their equipment.
3.2 Awareness of Safety Hazards
(a) Before attempting to work on the equipment the personnel who are going to install, commission, or operate the
equipment must be qualified and fully aware of all the manufacturers and suppliers recommendations and instructions.
(b) Ensure that the all the recommendations specified in the instruction manuals are maintained as stated in the contents.
4. Electrical Safety
(a) Ensure that the person who works on the equipment is a qualified electrical engineer/technician who is competent in
the safety aspects and operational mode of the equipment.
(b) If the electrical supply to the equipment is supplied by means of a portable trailing cable, protective devices such as
an Earth Leakage Circuit Breaker (ELCB) must be installed.
This protective device must have a very high sensitivity (20-30mA).This device is also referred to as a residual current
device(R C D) within the electrical supply circuitry for personnel protection.
(c) The supply cable must be sized accordingly for all fault and physical conditions pertaining to its use. The supply
network must also incorporate a protection device that will disconnect and isolate the supply voltage in the case of an
overload in a specified period of time without causing any damage to the equipment. (An overload relay)
5. Installation
(a) On receipt of the equipment extreme care should be used to avoid damage to the equipment on handling and
unpacking. If slings are used ensure they are held on a rigid part of the equipment, the structure. In the case of a
mechanical lift such as a fork lift ensure the lifting forks are beneath the structure framework so that no damage will
occur during the lifting operation.
(b) In some cases it is imperative that the equipment be installed on a level and solid foundation
5.1 Electrical Supply Cables
(a) The normal color code of the power cables supplied on this equipment is as follows:
- Black----------------------------Line.
- Gray or white -----------------Neutral.
- Green-Yellow-----------------Ground.
(b)The three phase power cable has five wires.
- Red, blue and black ---------Line.
- Light gray or white ----------Neutral.
- Green-Yellow ----------------Ground.
5.2 General Precautions for Equipment with Water Including Evaporative Cooling Towers
(a) Any water contained in the system should be drained regularly. If it is left in the system for a long period of time
without circulation it will stagnate.
(b) The equipment should be flushed regularly with clean water.
(c) Impurities in the water will cause scale or algae and must be cleaned on a regular basis. An anti rust additive such as
used in the automobile industry is recommended to inhibit this process.
(d) The water should be at temperature under 45 degrees C to maintain effectiveness.
(e) Many of the problems encountered with water contamination can be reduced and prevented by means of a water
treatment program being introduced using the expertise available locally or on site.
