Application Guidelines
It should ensure that the refrigeration system
which adopts this condensing unit, wherever
possible to integrate pump down features.
This is to avoid liquid compression which
could damage the compressor.
Ensure that new compressors are not
subjected to liquid abuse. Turn the crankcase
heater on 12 hours before starting the
compressor to avoid oil dilution and bearing
malfunction.

Outdoor ambient Min: -20 0 C, Max: 43 0 C (except -B1-
M-3, where head pressure control is
recommended to be integrated for
ambient below 10

erratic expansion valve operation)
Maximum pipe run Fusion: 25m
Fusion scroll: 50m
Suction line shall be insulated to avoid:
•
High superheat during high ambient condition can
create high discharge temperature.
•
Too low superheat during low ambient condition that
can condense refrigerant inside suction line.
Health and Safety
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.
General information
Before Installation
•
Ensure the units received are the correct models for the
intended application.
•
Ensure the refrigerant, voltage and maximum working
pressure are all suitable for the proposed application.
•
Check there is no damage to the units. Any damage
should be reported 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 operators 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 operators
should/must 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 all the time.
•
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 fitted
all the time.
•
Use of the units outside of the design conditions and the
application for which the units were intended may be
