General - Carrier AquaForce 30XV140 Controls, Start-Up, Operation, Service And Troubleshooting Instructions

WARNING
DO NOT VENT refrigerant relief valves within a building.
Outlet from relief valves must be vented in accordance
with the latest edition of ANSI/ASHRAE (American
National Standards Institute/American Society of Heating,
Refrigerating and Air-Conditioning Engineers) 15 (Safety
Code for Mechanical Refrigeration). The accumulation of
refrigerant in an enclosed space can displace oxygen and
cause asphyxiation. Provide adequate ventilation in
enclosed or low overhead areas. Inhalation of high concen-
trations of vapor is harmful and may cause heart irregulari-
ties, unconsciousness or death. Misuse can be fatal. Vapor
is heavier than air and reduces the amount of oxygen avail-
able for breathing. Product causes eye and skin irritation.
Decomposition products are hazardous.
WARNING
DO NOT USE TORCH to remove any component. System
contains oil and refrigerant under pressure.
To remove a component, wear protective gloves and gog-
gles and proceed as follows:
a. Shut off electrical power to unit.
b. Recover refrigerant to relieve all pressure from sys-
tem using both high-pressure and low pressure ports.
c. Traces of vapor should be displaced with nitrogen and
the work area should be well ventilated. Refrigerant in
contact with an open flame produces toxic gases.
d. Cut component connection tubing with tubing cutter
and remove component from unit. Use a pan to catch
any oil that may come out of the lines and as a gage
for how much oil to add to the system.
e. Carefully unsweat remaining tubing stubs when nec-
essary. Oil can ignite when exposed to torch flame.
Failure to follow these procedures may result in personal
injury or death.
CAUTION
Standard Tier units (units with S in the 10th position of
the model number) must have the condenser fan(s) rota-
tion verified to ensure proper phasing. Correct rotation
is counter-clockwise (reference arrow on fan hub). Swap
any two incoming power leads to correct condenser fan
rotation before starting chiller. Operating the unit with-
out testing the condenser fan(s) for proper phasing could
result in equipment damage.
CAUTION
DO NOT re-use compressor oil or any oil that has been
exposed to the atmosphere. Dispose of oil per local codes
and regulations. DO NOT leave refrigerant system open to
air any longer than the actual time required to service the
equipment. Seal circuits being serviced and charge with
dry nitrogen to prevent oil contamination when timely
repairs cannot be completed. Failure to follow these proce-
dures may result in damage to equipment.
This unit uses a microprocessor control system. Do not
short or jumper between terminations on circuit boards or
modules; control or board failure may result.
Be aware of electrostatic discharge (static electricity) when
handling or making contact with circuit boards or module
connections. Always touch a chassis (grounded) part to dis-
sipate body electrostatic charge before working inside con-
trol center.
Use extreme care when handling tools near boards and
when connecting or disconnecting terminal plugs. Circuit
boards can easily be damaged. Always hold boards by the
edges and avoid touching components and connections.
This equipment uses, and can radiate, radio frequency
energy. If not installed and used in accordance with the
instruction manual, it may cause interference to radio com-
munications. It has been tested and found to comply with
the limits for a Class A computing device pursuant to Inter-
national Standard in North America EN 61000-2/3 which
are designed to provide reasonable protection against such
interference when operated in a commercial environment.
Operation of this equipment in a residential area is likely to
cause interference, in which case the user, at his own
expense, will be required to take whatever measures may
be required to correct the interference.
Always store and transport replacement or defective boards
in anti-static shipping bag.
To prevent potential damage to heat exchanger tubes,
always run fluid through heat exchanger when adding or
removing refrigerant charge. Use appropriate antifreeze
solutions in evaporator fluid loop to prevent the freezing of
heat exchanger or interconnecting piping when the equip-
ment is exposed to temperatures below 32 F (0° C). Proof
of flow switch is factory installed on all models. Do NOT
remove power from this chiller during winter shut down
periods without taking precaution to remove all water from
heat exchanger. Failure to properly protect the system from
freezing may constitute abuse and may void warranty.
IMPORTANT: If the compressor VFD enclosure is
removed for service, it must be reinstalled to protect
the drive from water intrusion. Failure to reinstall the
compressor VFD enclosure may constitute abuse and
may void warranty.
