1.2.3.1 Electric Box Access
The electrical components are protected behind dual
hinged access doors located on the left side of the
unit. The access doors are safety interlocked with the
service disconnect switch preventing the doors from
opening when the switch in the “On” position. The
switch must be turned “Off” to gain access to the
electrical components.
1.2.3.2 Circuit Breakers/ Motor Start Protectors
Individual overload protection is provided by circuit
breaker(s) and motor start protectors. These switches
must be manually re-set once the overload condition is
cleared.
1.2.3.3 Pumps
Multi-stage centrifugal pumps are located in the right
side of the unit to circulate the coolant through the
system. A hinged access door is located on the right
side of the unit. This door may be opened to gain
access to the pump section.

1.2.3.4 Expansion T ank
An expansion tank has been provided on the chilled
water side of the unit to compensate for thermal
expansion of the coolant. An air vent is mounted on
top of the fluid separator .
1.2.3.5 Heat Exchangers
Constructed of 316 stainless steel with brazed plate fin
construction, the evaporator heat exchangers are for
the exchange of heat from the process water/glycol
coolant to the refrigerant.
1.2.3.6 Receivers
Receivers are provided for each refrigeration circuit for
storage of excess refrigerant in the refrigeration cycle.
1.2.3.7 Compressors
The compressors used in this unit are scroll compressors mounted inside the unit on vibration absorbers to
eliminate noise and vibration during operation. The
scroll compressor is designed around two identical
spirals or scrolls that, when inserted together, form
crescent shaped pockets. During a compression
1-2
(©October, 2006)
CyberChiller Series Installation, Operation & Maintenance Manual
cycle, one scroll remains stationary while the other
scroll orbits around the first. As this motion occurs,
gas is drawn into the scrolls and moved in increasingly
smaller pockets toward the center . At this point, the
gas, now compressed to a high pressure, is discharged from a port in the center if the fixed scroll.
During each orbit, several pockets of gas are compressed simultaneously , creating smooth, nearly
continuous compression.
Due to the design of the scroll compressor, the internal
compression components always start unloaded even
if the system pressures are not balanced. In addition,
since internal compressor pressures are always
balanced at start-up, low voltage starting characteristics are excellent for scroll compressors
With fewer moving parts, the
scroll compressor sets the
industry standard for reliability among one and a half to
twelve horsepower compressors. The compressor’s
simple design and proven
day-to-day performance
means less maintenance
calls for field personnel.
The scroll compressor has
demonstrated superior
durability . Its axial and radial
compliance make the scroll
compressor more tolerant to liquid refrigerant and
debris - two of the most common causes of system
failure.
The scroll compressor is quiet, but not silent. On
average, the compressor is up to five decibels quieter
than standard piston compressors. A scroll compressor, however , has different sound characteristics from
reciprocating compressors. These sounds do not
affect system reliability or performance.
Upon shut-down of a normal run cycle, the compressor
will run backwards for one or two seconds as the
scrolls internal pressures are equalized. A short
reverse rotation “burp” will result. This sound is normal.
A check valve in the discharge tube of the compressor
prevents the compressor from running backwards for
more than a second or two. This normal direction
reversal of the scrolls at shut down has no effect on
compressor reliability .
Each scroll compressor comes equipped with a
crankcase heater, used to evaporate any liquid that
may have migrated to the compressor during extended
periods on non-operation (>12 hours). The crankcase
heaters are equipped with over current protection.
CAUTION
Prior to initial start-up (only when main power
has been disconnected for 12 hours or longer),
allow at least ten (10) minutes (two (2) hours is
recommended) with main power reconnected.
This will allow sufficient time for the crankcase
heaters to evaporate any liquid that may have
migrated to the compressor crankcase. When
this procedure is completed, the CyberChiller is
ready to be run.
Automatic, staged starting of the compressors is
provided to prevent an in rush of current to the
CyberChiller. High and low pressure safety switches
prevent operation of the compressor during high or low
pressure conditions.
1.2.3.8 Strainer
A “Y” strainer is included to remove any debris that
may be circulated to the chiller.
1.2.4 Safety Features
Low and high-pressure switches are provided for each
refrigeration circuit. The pressure switches are nonadjustable encapsulated control switches. If a high
pressure switch is tripped for any reason, it must be
manually reset. The cause for tripping of the high
pressure switch must be determined. The low pressure
switches are reset automatically . These pressure
switches are installed as safety devices and will help
prevent compressor failure or other serious damage to
the system.
A flow switch is provided which will disable the refrigeration circuits if the coolant flow drops below a preset limit.
A blocked flow bypass valve is recommended for field
installation to ensure proper return flow to the chiller at
all times.
Manual reset circuit breakers will open to de-energize
a failed component if electrical overload conditions are
encountered.

CyberChiller Series Installation, Operation & Maintenance Manual
CAUTION
All personnel working on or near equipment
should be familiar with hazards associated with
electrical maintenance. Safety placards/stickers have been placed on the unit to call attention to all personal and equipment damage hazard areas.
CAUTION
Ensure the unit is properly phased. Improper
phasing can cause severe damage to the compressor.
W ARNING
Refrigerant (R-22 or R-407C) is used with this
equipment. Death or serious injury may result if
personnel fail to observe proper safety precautions. Great care must be exercised to prevent
contact of liquid refrigerant or refrigerant gas, discharged under pressure, with any part of the
body . The extremely low temperature resulting
from the rapid expansion of liquid refrigerant or
pressurized gas can cause sudden and irreversible tissue damage.
As a minimum, all personnel should wear thermal protective gloves and face-shield/goggles
when working with refrigerant. Application of excessive heat to any component will cause extreme pressure and may result in a rupture.
Exposure of refrigerant to an open flame or a
very hot surface will cause a chemical reaction
that will form carbonyl chloride (hydrochloric/hydrofluoric acid); a highly poisonous and corrosive gas commonly referred to as PHOSGENE.
In its natural state, refrigerant is a colorless, odorless vapor with no toxic characteristics. It is
heavier than air and will disperse rapidly in a
well-ventilated area. In an unventilated area, it
presents a danger as a suffocant.
Always refer to the manufacturer's MSDS provided with the unit.
W ARNING
Avoid skin contact or inhaling fumes from any
acid formed by burn out of oil and refrigerant.
Wear gas mask if area is not thoroughly ventilated. Wear protective goggles or glasses to
protect eyes. Wear rubber gloves to protect
hands. Use care to avoid spilling compressor
burnout sludge. If sludge is spilled , clean area
thoroughly.
W ARNING
When performing soldering or desoldering operations, make certain the refrigeration system
is fully recovered and purged and dry nitrogen is
flowing through the system at the rate of not
less than 1-2 CFM (.03 - .06 M³/minute).
CAUTION
Certain maintenance or cleaning procedures
may call for the use and handling of chemicals,
solvents, or cleansers. Always refer to the
manufacturer's Material Safety Data Sheet
(MSDS) prior to using these materials. Clean
parts in a well-ventilated area. Avoid inhalation
of solvent fumes and prolonged exposure of skin
to cleaning solvents. Wash exposed skin thoroughly after contact with solvents.
CAUTION
Do not use cleaning solvents near open flame or
excessive heat. Wear eye protection when blowing solvent from parts. The pressure-wash should
not exceed 30 psig. Solvent solutions should be
disposed of in accordance with local and state
regulatory statutes.
CAUTION
Units must be kept in its normal installed position. If the unit is not kept level and vertical,
damage to the unit's compressors will result.
