Health and Safety
General information
Before Installation
•
Ensure the units received are the correct models for the intended application.
•
Ensure the refrigerant; electrical supply and MWP are all suitable for the proposed application.
•
Check there is no damage to the units. Any damage should be advised to the supplier immediately.
•
Check that the proposed equipment locations are suitable and provide adequate support for the weight of the units.
Offloading and Lifting
•
Whenever a condensing unit is lifted, it should be from the base and, where possible, all packing and protection is kept in
position.
•
If lifting equipment is required, ensure that it is suitable, certificated, and that the operatives are qualified to use it.
•
When using a fork-lift or pallet truck to lift the unit, the two support points should be sufficiently apart to give stability when
lifting and suitably placed to distribute the load on the forks.
•
If slings are used, care should be taken to ensure that the slings do not crush the casework or coil.
•
When lifting by crane, use spreader bars to prevent compressing the top of the equipment.
•
Do not drop the unit. Should this inadvertently happen, it should be immediately unpacked and inspected for damage.
•
Use the appropriate spreader bars/lifting sling with the holes and lugs provided.
During Installation and subsequent maintenance
•
Installation and maintenance are to be performed only by qualified personnel who are familiar with local codes and
regulations, and experienced with this type of equipment.
•
Safe working methods are identified and operatives have suitable Personal Protective Equipment (PPE).
•
Ensure the working area has adequate ventilation during brazing procedures.
•
The units contain moving machinery and electrical power hazards, which may cause severe injury or death. Disconnect and
shut off power before installation or service of the equipment.
•
Refrigerant release into the atmosphere is illegal. Proper evacuation, recovery, handling and leak testing procedures must be
observed at all times.
•
Units must be earthed.
•
No maintenance work should be attempted prior to disconnecting the electrical supply.
•
The electrical covers and fan guards must remain fitted at all times.
•
Use of the units outside of the design conditions and the application for which the units were intended may be unsafe and be
detrimental to the units, regardless of short or long term operation.
•
The units are not designed to withstand loads or stresses from other equipment or personnel. Such extraneous loads or
stress may cause failure/leak/injury.
Important Note:
Only qualified personnel, who are familiar with refrigeration systems and components including all controls,
should perform the installation and start-up of the system. To avoid potential injury, use care when working
around coil surfaces or sharp edges of metal cabinets. All piping and electrical wiring should be installed in
accordance with all applicable standards and local by-laws.
