Features and Benefits
MidrangeVertical Self-Contained air conditioners, available in 3 to 15-tons, are single package unitsdesigned for low cost installation in the conditioned space or equipment room. Durableconstruction, strict quality control, and demanding factory testing ensure reliability from start-upthrough years of operation. All units are shipped fully factory assembled and tested — therebyreducing field labor, installation time, and costs.
Units are easy to convert from vertical to horizontal discharge arrangements. Unit returnconvertible for front or rear return air offers flexibility to match most building configurations.Discharge fan section removable to allow passage through standard height doorway.
Discharge can be either free or ducted. Power and water connections are available from either sideof the unit adding to the unit flexibility.

PKG-PRC012Q-EN 5
Application Considerations
CTA Unit Location
Unobstructed condenser airflow is essential to maintain capacity and operating efficiency. Whendetermining unit placement, give careful consideration to assure sufficient airflow across thecondenser coils.Avoid these two detrimental conditions: warm air recirculation and coil starvation.Both warm air recirculation and coil starvation cause reductions in unit efficiency and capacitybecause of the higher head pressure associated with them. In more severe cases, nuisance unitshutdowns will result from excessive head pressures.
Clearance
Ensure vertical condenser air discharge is unobstructed. While it is difficult to predict the degreeof warm air recirculation, a unit installed with a ceiling or other obstruction above it will experiencea capacity reduction that will reduce the maximum ambient operation. Nuisance high headpressure trip outs may also occur.The coil inlet must also be unobstructed. A unit installed closerthan the minimum recommended distance to a wall or other vertical riser will experience acombination of coil starvation and warm air recirculation.This may result in unit capacity andefficiency reductions, as well as possible excessive head pressures.
Reference the service clearance section for recommended lateral distances.
Ambient Limitations
Standard ambient control allows operation down to 45°F (7.2°C) with cycling of condenser fans.Units with the low ambient kit option are capable of starting and operating in ambient temperaturesdown to 0°F (-17.8°C). Optional low ambient kit units use a condenser fan motor speed controllerthat controls condenser capacity by modulating condenser airflow in response to saturatedcondenser temperature or ambient temperature. Maximum cataloged ambient temperatureoperation of a standard condenser is 125°F (46.1°C). Operation at design ambient above 125°F canresult in excessive head pressures. For operation above 125°F, contact the localTrane sales office.

Selection Procedure
Follow this process to select a midrange self-contained unit.
Step 1. Load
Determine the load requirements for heating and cooling, include outside air. UseTrane’s loadestimate program or any standard method.
Step 2. UnitType
Self-contained air conditioners are available in either water-cooled or remote air-cooled models tomatch individual needs.
Step 3. Select the Unit
The conditions under which the unit must operate and the design load will give the final selection.
Selection Example
Design conditions for a water-cooled unit with airflow = 2,000 cfm at 0.5-inch duct static pressure.
Entering air temperature = 80/67°F
Total gross capacity required = 66,400 Btu/h
Entering water temperature = 85°F
Leaving water temperature = 95°F
Unit Selection
Tentatively select a 5-ton unit, model SCWJ050. Refer to Table 19, p. 26 to obtain gross total andsensible unit capacities, gpm, and leaving water temperature at nominal conditions:
Total capacity = 68.1 MBh
Sensible capacity = 49.2 MBh
Water flow rate = 16.2 gpm
Leaving water temperature = 95°F (all capacity tables assume 10° T)
The SCWJ050 meets the total and sensible capacities and other design requirements.
Refer to the fan data Table 4, p. 12 to determine approximate brake horsepower and fan rpm:
Fan brake horsepower = 0.73 bhp
Fan rpm = 1020 rpm
Determine net capacities by subtracting fan motor heat from gross capacities:
3.98 X 0.73 bhp = 2.9 MBh
Net total capacity = 68.1 MBh – 2.9 MBh = 65.2 MBh
Net sensible capacity = 49.2MBh - 2.9 MBh = 46.3 MBh

Notes: 1. All capacities shown are gross and do not consider indoor fan heat. 2. Use the following equation to compute indoor fan motor heat and calculate the net capacities: Fan motor heat (MBh) = 3.98 x
fan motor bhp [Net MBh capacity = gross MBh capacity - fan motor heat MBh] 3. For capacity data at values other than 10° T, refer to Table 24

Notes: 1. All capacities shown are gross and do not consider indoor fan heat. 2. Use the following equation to compute indoor fan motor heat and calculate the net capacities: Fan motor heat (MBh) = 3.98 x fan motor
bhp [Net MBh capacity = gross MBh capacity - fan motor heat MBh] 3. For capacity data at values other than 10° T, refer to Table 24.

RLA = rated load amps.Compressor LRA = locked rotor amps.Fan motor LRA = locked rotor amps,N.E.C.Table 430 - 151.FLA = Full load amps, N.E.C.Table 430 - 150
Voltage utilization range is ±10%
Minimum circuit ampacity (MCA)= 1.25 x largest motor amps (FLA or RLA) + the sum of the remaining motor amps.
Maximum fuse size (MFS) and maximum circuit breaker size (MCB) = 2.25 x largest motor amps(FLA or RLA) + the sum of the remaining motor amps.
Note: If the rating value determined does not equal a standard current rating of over currentprotective device, use the next lower standard rating for the marked maximum rating.
