Important Notice
Refrigerant EmissionControl
Gas conservation and emission
reduction should be accomplished by
adhering to operational and service
procedures recommended by Trane,
withspecial attention tothefollowing:
The refrigerant used in any type of AC
equipment must be always recovered
and/or recycled for reuse, reclaimed or
completely destroyed after being
removed from the unit. Never release
the refrigerant to the atmosphere.
Always consider the possibility of
recyclingor reprocessingthe refrigerant
before starting the reclaim process by
any method.
The ARI 700 Standard covers
questions about recovered refrigerant
andacceptablequality.
Use only approved and safe cylinders.
All applicable safety and shipping
standards must be met during the
transportationof refrigerant containers.
Recycling equipment should be used to
minimize emissions during the transfer
of refrigerant gas. Always use methods
that generate the lowest possible
vacuum during the recovery and
condensation of refrigerant into the
cylinder.

Operation
Specificallydevelopedtokeeptheproper
pressure of the air-cooled condenser
during periods of low conditions of
externalenvironment.
General
Theair-cooledcondensersapplicationfor
operationduringthewholeyearorduring
lowtemperaturesperiodsrequiressome
means of control to keep condensing
pressures that assure a proper system
operation. It is essential that the proper
pressure of the refrigerant liquid is
controlledto:
1. Keep the liquid subcooling and avoid
gasbubblesintheliquidline.
2. Provide an adequate pressure at the
admission sideof thethermostaticvalve
High Pressure Control Valve - Head
MasterAlco to obtain a sufficient drop pressure by
meansofthevalvegate.
Without a proper condensing pressure
control, serious consequences like bad
cooling and components damage may
occur. Alco Head Master control offers
an efficient and economical method to
solve this usual problem in the industry
of air-cooledcondensers.
Operation
Thepressurecontrolvalve(HeadMaster)
isathree-waymodulatedvalvecontrolled
bythehighpressure. Theloadedcupula
makesa constant pressureover thetop
of the diaphragm. In high temperature
environments, the gas derivation that
enters in gate B is admitted under the
diaphragm where it puts itself against
the loadpressureof thecupula. Thegas
pushesthediaphragm up andallowsthe
support disc to close the superior
support,preventingtheflowof thegateB
(discharge gas), while the flow coming
from gateC doesnot standrestrictions.
When the room temperature falls, the
air-cooled condenser goes by a
corresponding decrease in the high
pressure. As the high pressure
(derivation) falls, it stops putting itself
against thecupulaloadpressureandthe
diaphragm moves downwards, moving
the stem and the support disc towards
thelowersupport.
Fig.02 - direction of gas inlet on valve
Fig. 03 - High pressure control valve
Important
This allows that the discharge gas
(derivation)isdosedinside thereceptor,
generating a higher pressure in the
discharge of the condenser. The higher
pressure in the condenser discharge
reduces the flow coming from gate C
andmakesthelevelof condensateliquid
raiseinthecondenser.

As in all high pressure control
applications, it is necessary an

the condenser is flooded. The recipient
has to be large enough to contain the

system consists of:
A. An operational load - the pounds of
refrigerant necessary to operate the
system during the climatic conditions of
summer(highroomtemperature).
B. An additional load that equals the

Maintenance Procedures
These sections describe maintenance
procedures to be performed as part of
the normal unitmaintenance program.
AirFilters
The washable permanent filters
provided with the AC units should be
cleaned using a solution of water and
neutral detergent.
Put the filters into the solution, brush
them, flush with cold water and then
apply acompressedairjet.
Replace throwaway filters.
Do not operatetheunitwithout filters.
Maintenance
Procedures
Sheaves and Belts
Check if the sheaves are properly
alignedandoperatingcorrectly.
1. Turn the sheaves by hand in order
tocheck if they can move freely.
2. Check motor and fan shafts. Both
shaftsshouldbeparallel toeachother.
3. Verify that fan and motor sheaves
are aligned. In case of sheaves with
different widths, align sheave centers,
as shown in Fig. 2.
4. Make surethe belt tension iscorrect.
This will increase the life of motor and
fanbearings.

SSC-SVN001F-EN 13
Fig. 08 - Belt Tension Adjustment
Fig. 07 - Belt Tension Meter
Unbalanced Voltage
An excessive unbalance between phases in
a 3-phase system will lead to motor
overheating and eventual failures.
The maximum allowable unbalance is 2%.
Voltage unbalance can be defined as 100 ti-
mes the maximum offset of the three
voltages (i.e. three phases) minus the mean
(regardless the sign), divided by the mean.
Example:
If the three voltages measured in a line are
221 V, 230 V and 227 V, theaverage willbe:
(221 + 230 + 227)/3 = 226 volts
The unbalance percentage is:
100 x (226 - 221)/226 = 2.2%
This result indicates the presence
of an unbalance above the maximum
allowable value of 0.2%. The phase
unbalance can result in a current unbalance
of 20%, leading to an increase in motor
winding temperature and reducing motor
life.
Belt Tension Measurement
A tension meter such as the one showed in
Fig. 3 will be required to measure the belt
Maintenance
Procedures
tension. The proper deflection is
determined by the result of the division of
the distance between sheaves by 64 (in-
ches). If a tension meter is not available,
press the belt with the thumb. The belt
should present an arrow of approx.
10 mm. If replacement for a new one is
required, stretch the belts and allow them to
work for several hours until they adapt to the
sheave channels, then stretch them again.
Liquid Sight Glass
When the sight glass displays bubbles, one
or more of the following problems may be
present:
a. Lack of refrigerant.
b. Clogged drier filter.
c. Expansion valve is too open.
d. Low subcooling.
e. Presence of non-condensables.
The yellow color indicates the presence of
residual humidity in the refrigerant circuit.
During normal operation the sight glass
display should be green with no bubbles,
indicating that the refrigerant load in the
refrigeration circuit is correct and that the
refrigerant is dehydrated.
Condenser Coil
The condenser coil should be cleaned with
a soft brush and compressed air jets or low
pressure water jets in the opposite direction
of normal air flow. Move the hose vertically
and adjust the hose pressure so that it
cannot damage the fins.
CAUTION:!
Do not crush the fins during the
cleaning process. This will impair
the heat exchange.

Preventive Maintenance
Periodical Preventive
Maintenance
Recordoperation conditions for thisunit
monthly. The operation datasheet can
be a preciousdiagnostic tool for service
personnel. By noticing trends in
operating conditions the operator can
often anticipate and prevent problem
situationsbefore theybecomeserious.
If theunit is notoperatingproperly, refer
to the section on abnormal conditions
at theend of thismanual.
Weekly Maintenance
When the equipment is operating for
approx. 30 minutes and the system is
stable, check the operating conditions
and perform the following checking
procedures:
Clean permanent air filters more
often, depending on the job site.
MonthlyMaintenance
Clean the permanent air filter.
Throwawayfiltersshouldbereplaced.
Check fan belt tension,
alignment andcondition.
Cleanthefanvolute.
Re-tightenall terminalscrews.
Clean the evaporator tray, the
hose and the condensate water drain.
Check the liquid line sight glass.
Leak-test and repair, if required.
When the liquid sight glass and
the operational conditions indicate lack
of gas, measure the system
overheating andsubcooling.
When operational conditions
indicate overload, remove the
refrigerant slowly (to minimize oil
losses) through the Schrader service
valveintheliquidline.
Inspect the system to detect
abnormal conditions. Use a reading
sheet to record unit conditions. A
reading sheet completed can be a
precioustool for service personnel.
QuarterlyMaintenance
Perform all monthly
maintenance tasks.
Check bearing and shave fixing
screwsandadjust then, if required.
Clean the condenser more
often, depending on the job site.
Clean the evaporator more
often, depending on the job site.
Check and writedown fan motor
and compressor operation voltages
and currents.
Test safety controls.
Check and write down
evaporator entering and leaving dry
bulbandwetbulbtemperatures.
Check suction and discharge
pressureswiththemanifold.
Measure and record the system
overheating.
Measure and record the system
subcooling.
Annual Maintenance
Perform all recommended
monthly and quarterly maintenance
tasks. Have a qualified technician to
check the adjustment and operation of
each control, and inspect and replace
countersor controls, if required.
Remove the cabinet panels and
remove rust spots.
Replace the thermal insulation
anddefectivegaskets.
Repair the external and internal
painting,if required.
Removerust.
Inspect and clean the
condenserpipes, if required.
Inspect the expansion valve
bulb. Clean it, if required. The contact
between the bulb and the suction line
should be excellent, and the bulb

Crankcase Resistance
Trane recommends the use of
crankcase when theload of the system
refrigerant load exceeds the refrigerant
compressor limit (RCL). The needs of
crankcase resistance are directly
related to the possibility of liquid
migration to the compressor, and
consequently causing poor lubrication
of it. Migration can occur during long
periods of compressor shutdown (over
8 hours). The crankcase resistance is
recommended to eliminate the liquid
migration when these downtime long
periods.The crankcase resistance must
be installed on the compressor housing
and below the removal oil point. The
crankcase resistance must remain
energized whilethecompressorisoff.
This will prevent the dilution of oil and
the bearingsoverload in the initial com-
pressor starts. When the compressor is
off, the crankcase temperature should

be kept at least 10°C above the
refrigerant temperature in the suction
side (low pressure side). This
requirement ensuresthat the refrigerant
will not be retained in the compressor
crankcase. Tests can be done to
ensure that the appropriate
temperature of the oil is maintained
below the ambient conditions
(temperatureandwind).
Therefore, for a temperature below -
5°C and an over 5m/s wind speed, it is
recommended that the resistors be
thermally isolated to limit the energy
losstotheenvironment.
Attention:
The strength of crankcase must be
energized at least 12 hours before
the startup of the compressor (with
the service valves open) and should
be maintained until the compressor
energized startup.
