•
Whenever the outdoor or indoor 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 operators are qualified to
use it.
•
When using a fork-lift or pallet truck to lift the outdoor
unit, the two support points should be sufficiently apart
to give stability when lifting and suitably placed to
distribute the load on the forks.
•
When using a pallet truck to lift the unpacked indoor
unit, protect the casing surface with cushion to avoid
damage on the drain pan. Two support points must be
sufficiently apart to give stability when lifting.
•
If slings are used, care should be taken to ensure that
the slings do not crush the casework or coil.
•
Do not drop the unit. Should this inadvertently happen,
it should be immediately unpacked and inspected for
damage.
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 operators
should have suitable Personal Protection Equipment.
•
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 always be observed.
•
Units must be grounded to the screw terminal labelled
•
No maintenance work should be attempted prior to
disconnecting the electrical supply.
•
The electrical covers and fan guards must remain
always fitted.
•
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.
Installation
Unit location and Fixing
Both indoor and outdoor units must be level in all directions.
Outdoor
•
The installer must fix the unit securely on installation
using the M8 bolt holes in the unit feet to prevent
instability from accidental contact.
•
It is recommended to install the outdoor unit on rubber
grommet or vibration dampers.
•
The units are not designed to withstand loads or stress
from other equipment or personnel. Such extraneous
loads or stress may cause failure/leak/injury.
•
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.
•
To achieve maximum cooling capacity, the installation
location for the condensing unit should be carefully
selected.
•
Install the outdoor unit in such a way so that hot air
ejected by the unit cannot be drawn in again (short
circuit of hot discharge air). Refer
Figure 2 .
Figure 2: Positioning of Condensing Unit
•
Ensure that there is no obstruction to air flow into or out
of the unit. Remove obstacles which block air intake or
discharge. Refer
Figure 3 .
Figure 3: Air Circulation for Condenser
•
Allow sufficient space for maintenance around the unit.
Refer
Figure 4 .
Figure 4: Installation Clearance (Outdoor
Unit)
•
The location must be well ventilated, so the unit can
draw in and distribute plenty of air thus lowering the
condensing temperature.
•
To optimize the unit running conditions, the condenser
coil must be cleaned at regular intervals.
Special attention should be given to an
outdoor unit installed near to the sea as this
can reduce unit lifespan due to corrosion of
metal parts.
