•
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 all
LEDs on frequency converter goes off 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 all the time.
•
Units must be earthed.
•
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 term or long-term operation.
•
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 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 (e.g., 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.
Installation
Unit location
•
To achieve maximum cooling capacity, the installation
location for the condensing unit should be carefully
selected.
•
Install the condensing unit in such a way so that hot air
ejected by the condensing unit cannot be drawn in
again (short circuit of hot discharge air). Allow
sufficient space for maintenance around the unit.
Figure 4: 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.
Figure 5: Air Circulation for Condenser
•
The location must be well ventilated, so the unit can
draw in and distribute plenty of air thus lowering the
condensing temperature.
•
Air leaving the condenser should avoid facing
prevailing wind, which impedes air flow and thus
causing high condensing temperature.
•
To optimize the unit running conditions, the condenser
coil must be cleaned at regular intervals.
•
The unit must be level in all directions.
•
It is recommended to install the unit on rubber grommet
or vibration dampers.
•
Models LRMIFS0300AXY1 and LRMIFS0600AXY1are
suitable for both ground and wall mounting on
brackets, but LRMIFS0900AXY1is only suitable for
ground mounting.
Special attention should be given if unit
installed near to the sea as this can reduce
unit lifespan due to corrosion of metal
parts.
