Capacity Control Steps
The Standard Capacity Control Steps are shown below.
Table 5
Selection Procedure Example
The following information should be determined:
1. Required total capacity = 430 MBh (125.9 kW)2. Saturated suction temperature = 50°F (10°C) 3. Condenser entering air temperature = 115°F (46°C)4. Power Supply (V/Ph/Hz) = 380/3/50
Enter capacity ratings from Table 5 at 115°F (46°C) condenser entering air temperature and select model AUMR 52040 having a cooling capacity of 437.8 MBh (128.3 kW) at 50°F (10°C) saturated suction temperature, compressor motor power input is 43.3 kW. For further details refer to physical data and specifications sheets.
Capacity ratings are based on sea level operation. Above sea level, apply the following corrections method.
Actual capacity (at level) = Sea level capacity x altitude correction factor (from Table 6).
Altitude Correction Factors
The unit ratings are based on sea level. Above sea level apply the following correction factors:

Field ConnectionsAUMR series self-contained heavy duty air cooled condensing units are designed for minimum field interaction.
Power hook-ups for AHU starter and fan interlock and control wiring of room unit as per Electrical hook-up diagram is all that is required to electrically connect any model of AUMR series .
Every AUMR series condensing unit requires, at most, field installed fused disconnect switches or circuit breakers, and room unit.
Refer below for a schematic representation of required field electrical hook-ups for a standard AUMR series condensing unit.
All field wiring must be done in accordance with applicable local and national codes.
For maximum recommended fuse sizes and minimum circuit amps for cable sizing, see Page 14 - 16 of this bulletin.
The AUMR series is then ready to provide cooling, on demand.

SINGLE UNIT INSTALLATION
Location and Space Requirements
Location and Space RequirementsDue to the vertical air flow discharge condenser design, it is recommended that certain precautions are to be taken before installation. There should be no obstruction on the air flow.
Orient the unit so that prevailing winds blow parallel to the unit length thus minimizing the effects on condensing pressure. If it is not practical to orient the unit in this manner, a wind deflecting shield should be considered.
It is also necessary to provide adequate clearance on all sides of the unit for service access and satisfactory performance. This will prevent excessive condensing temperatures and enhance system performance and operating economy.
A flat concrete foundation or floor which can support the weight of the equipment must be provided as the unit must be level for proper operation and functioning of controls.
Under certain critical conditions it is recommended that vibration isolators of rubber-in-shear or spring type be installed under the base.
The isolators must be designed for the operating weight of the unit. For operating load points refer to Loading Points Data (page No.19).Correct selection of types of isolators depends upon application and structure.

Single Circuit Unit Shown. For Dual circuit units, piping of second circuit is similar.
Refrigerant Piping
Correct design and size of refrigerant piping is necessary for proper operation. The refrigerant piping generally should be designed to accomplish the following:
a. To ensure proper refrigerant feed to the evaporator.
b. To provide practical refrigerant line sizes without excessive pressure drop.
c. To maintain uniform return of lubricating oil to the compressor.
d. To prevent refrigerant from entering the compressor and causing compressor damage due to "slugging".
Field Expansion Valve Selection
The following recommendations should be taken into consideration when selecting expansion valves in field.
1. Expansion valves should be installed as close to the evaporator as possible, mounted directly to the distributor.
2. The following possible sources of pressure drop to be considered:
a. Friction losses through refrigerant lines.
b. Pressure drop across valves and controls.
c. Pressure drop due to vertical lift of liquid line for R-410A 1°F (0.55°C) sub cooling must be allowed for each 10 ft (3m) vertical rise in order to avoid flash gas forming due to the weight of the column of liquid refrigerant.
SKM AUMR Series units are designed with a sub cooling circuit enough to sub cool the liquid 10°F (5.55 °C), which gives the liquid maximum 100 ft. (30m) lift without additional sub cooling. Liquid suction heat exchanger can be used for additional sub cooling in order to avoid flash gas forming.
Matching DX Coil Selection
For single circuit AUMR Series, the DX coil selection in a MAH or other air handler from SKM should be based on total capacity. For dual circuit AUMR Series, extra care should be exercised and correspondingly split, by face area or number of rows to correspond and match the capacity split available in the dual circuited AUMR Series selected. For optimum matching the DX coil should be ordered from SKM as well.
SKM provides correct no. of feeds and circuits and properly sized distribution to ensure the correct split on the DX coil is made available to match the particular selected AUMR Series model.

Recommended Refrigerant Line Sizes - 50Hz & 60HZ
SKM AUMR Series Condensing Units are designed for satisfactory operation with single suction line.1. Suction Line sizing selection recommendation in Table 15 & 16 is based on 2ºF temperature drop.2. Double suction risers, for applications with systems having large variations in capacity , are recommended to ensure proper
oil flow up and return to compressor.
3. Liquid line sizing selection recommendation in table 15 & 16 is based on 2ºF temperature drop.4. Recommended line sizes in Table 15 & 16 are for guidance only. For detailed proper piping, consult recognized piping
references like ASHRAE Guide and Data Book for assistance.
5. Suction and liquid line sizes are based on equivalent lengths.
SKM is not responsible for faulty or improper design or sizing of refrigerant lines. The above recommendations do not incorporate necesarry slopes. etc. that may be required on horizontal risers, etc.
