Installation Requirements
Location Requirements
Sound consideration
The most effective form of acoustical isolation is to
locate the unit away from any sound sensitive area.
Structurally transmitted sound can be reduced by
elastomeric vibration eliminators. Spring isolators are
not recommended. Consult an acoustical engineer in
critical sound applications.
For maximum isolation effect, isolate water lines and
electrical conduit. Rubber isolated piping hangers can
be used to reduce the sound transmitted through water
piping. To reduce sound transmitted through electrical
conduit, use flexible electrical conduit.
EU and Local Regulations codes on sound emissions
should always be considered. Since the environment
in which a sound source is located affects the sound
pressure, unit placement must be carefully evaluated.
Clearances
When installing the unit, provide enough space around
the unit to allow the installation and maintenance
personnel unrestricted access to all service points.
Unobstructed flow of condenser air is essential to
maintain chiller capacity and operating efficiency. When
determining unit placement, give careful consideration to
ensuring a sufficient air flow across the condenser coils
heat-transfer surface.
In case of enclosure around the unit, the height of the
enclosure must not be higher than the unit itself. If the
enclosure is higher than the unit, restrictive airflow
louvers should be fitted to ensure fresh air supply.
Installation Responsibilities
Generally contractor must do the following Items when
installing a CGAF / CXAF unit:
1. Install the unit on a flat foundation strong enough
to support unit loading and level (within 5 mm
across the length and width of the unit).
2. Install the units as per instructions contained in
this manual.
3. Where specified, provide and install valves in
the water piping upstream and downstream of
the evaporator water connections, to isolate the
evaporator for maintenance, and to balance and
trim the system.
4. Furnish and install a water flow prove device and/
or auxiliary contacts to prove chiller water flow.
5. Furnish and install water pressure gauges in the
inlet and outlet of the evaporator water box.
6. Supply and install an air vent cock to the top of
the evaporator or evaporator piping.
7. Furnish and install strainers ahead of all pumps
and automatic modulating valves.
8. Provide and install field wiring according to
schematics provided in the control panel.
9. Install heat tape and insulate the chilled water
lines and any other portion of the system, as
required, to prevent sweating under normal
operating conditions or freezing during low
ambient temperature conditions.
10. Ensure that the compressor and compressor
heaters have been operating for a minimum of
24 hours before starting. Failure to do so may
result in equipment damage.
11. Start the unit under supervision of a qualified
service technician.
Lifting and Moving Instructions
A specific lifting method is recommended, which can be
described as follow:
1. Lifting points are built into the unit, see lifting
instruction label on the unit.
2. Slings and spreader bar must be provided by
crane operator and attached on the lifting points.
3. Use the 4 rigging points which are built into the
unit.
4. The minimum lifting capacity of each sling as
well as the spreader bar must be higher than the
tabulated unit shipping weight.
CAUTION!
Lift and handle with care. Avoid shocks while
handling.
Details of lifting instruction and container pull out are
given in the drawings specific for lifting and handling
shipped with the unit.
WARNING! Heavy Objects! Ensure that all the lifting
equipment used is properly rated for weight of the
unit being lifted. Each of the cables (chains or slings),
hooks, and shackles used to lift the unit must be capable
of supporting the entire weight of unit. Lifting cables
(chains or slings) may not be the same length. Adjust as
necessary for even unit lift. Other lifting arrangements
could cause equipment or property damage. Failure
to follow instructions above or properly lift unit could
result in unit dropping and possibly crushing operator/
technician which could result in death or serious injury.
WARNING! Improper Unit Lift! Test lift unit
approximately 10 cm to verify proper center of gravity lift
point. To avoid dropping of unit, reposition lifting point if
unit is not level. Failure to properly lift unit could result in
unit dropping and possibly crushing operator/technician
which could result in death or serious injury and possible
equipment or property- only damage.
