Health and Safety
DAIKIN Condensing Unit has to be installed and commissioned by competent
personnel, who are familiar with refrigeration systems and components including all
controls. 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 laws.
General Information
Before Installation
•
Ensure the units received are the correct models for the intended application.
•
Ensure the refrigerant; electrical supply and maximum working pressure (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 and wait until the rotating blades stop 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 grounded to the screw terminal labelled
•
No maintenance work should be attempted prior to disconnecting the electrical supply.
•
The fan guards must remain always fitted when put under operation.
•
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 term 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.
•
The installer must fix the unit securely on installation using the M8 bolt holes in the unit feet to prevent
instability from accidental contact or from exposure to the elements (example: wind).
•
The units are not designed to operate with any restrictions such as heavy snowfall around them. Additional
measures (such as shielding of the units) shall be implemented as required.
