GENERAL
1.1 RECEIVING INSTRUCTIONS
A. Remote air-cooled condenser units are generally shipped skid mounted from the original
manufacturer. This is a separate item from the chilling unit.
B. Unbox the unit before accepting delivery. Check for visible damage and document any
evident damage on the delivery receipt or refuse the shipment. Shipping damage is the
responsibility of the carrier.
C. In order to expedite payment for damages, should they occur, follow proper procedures
and keep detailed records. Take photographs of any suspected damage.
1.2 INTRODUCTION
A. This manual covers remote air-cooled condensers.
B. The intent of this manual is to serve as a guide in the installation, operation and
maintenance of the unit. Improper installation can lead to equipment damage and poor

duetothepresenceofhighvoltage.Onlyqualiedpersonnelshouldinstall,startupand
service this equipment.
E. When working on this equipment, observe precautions in literature and on tags, stickers
and labels located on the equipment. Wear work gloves and safety glasses.
F. Before installing and operating the unit, be aware of and follow any local laws and codes
that apply to the installation.
INSTALLATION
2.1 LOCATION
A. Before placing the unit into position a review of the most suitable location must be made.
B. The condenser should be placed as close to the indoor chiller components as possible.
Installation costs rise and performance is reduced the further the condenser is placed
away from the chiller.
B. This condenser is designed for outdoor installation. It may be installed on a roof or
ground level concrete pad. The roof or concrete pad must be able to support the
operating weight of the condenser.
C. A number of factors must be taken into consideration when selecting a location.
Most important is the provision for a supply of ambient air to the condenser and
removal of heated air from the condenser area. Higher condensing temperatures,
decreased performance, and the possibility of equipment failure may result from
inadequate air supply.
Other considerations include:
1. Distance from indoor chiller components.
2. Loading capacity of the roof or floor.
3. Distance to suitable electrical supply.
4. Accessibility for maintenance.
5. Local building codes.
6. Adjacent buildings relative to noise levels.
D. Walls or Obstructions
1. All sides of the unit must be a minimum of 4 feet (1.24m) away from any wall or
obstruction.
2. Overhead obstructions are not permitted. If enclosed by three walls, the
condenser must be installed as indicated for units in a pit.

E. Units in Pits
1. The top of the condenser must be level with, or above the top of the pit.
2. A minimum of 8 feet (2.25m) is required between the unit and the pit walls.
F. Multiple Units
1. A minimum of 8 feet (2.25m) is required between multiple units placed side by
side.
2. If the units are placed end to end the minimum distance between each unit is 4
feet (1.25m).
G. Louvers/Fences
1. Louvers/fences must have a minimum of 80% free areas and 4 feet (1.25m)
clearance between the unit and louvers/fence.
2. Height of louver/fence must not exceed top of the unit.

2.2 LIFTING INSTRUCTIONS
A. Air-cooled condensers are large, heavy mechanical equipment and must be handled as
such.
B. Afullyqualiedandproperlyequippedcrewwithnecessaryriggingshouldbeengagedto
set the condenser into position.
C. Under no circumstances should the coil headers or return bends be used in lifting or
moving the condenser.
D. Ensure the unit is placed in a level position to ensure proper drainage of liquid refrigerant
and oil.
E. Lowerunitintoverticalairowposition,takingcarenottodamagecoilsurfaceunderunit.
F. Attach legs and any angle or cross bracing per manufactures instructions that are
included with the condenser. The legs should be securely anchored to the building
structure or concrete pad. The weight of the condenser alone is not enough to hold in
place during a strong wind, the legs must be anchored.
Single wide unit shown with legs, cross and angle braces attached.

G. Lifting holes have been provided at the corners or along sides for attaching lifting slings.
Spreader bars must be used when lifting so that lifting forces are applied vertically. If
more than 4 lifting holes are provided on the condenser, more than four lifting points
should be used.
2.3 REFRIGERANT PIPING
A. Allrefrigerantpipingmustbeinstalledbyaqualiedrefrigerantmechanic.
B. The importance of correct refrigerant pipe sizing and layout cannot be over-emphasized.
Failure to observe proper refrigerant piping practices can result in equipment failure
which may not be covered under warranty.
C. All air-cooled condensers are supplied complete with headers and refrigerant connections
sized for connecting the standard refrigeration tubing.
D. Theseconnectionsmaybotbethesameastheactuallinesizedrequiredfortheeld
installation.Refertoarecognizedsource(ASHRAEcharts,manufacturer’sengineering
manuals etc) for line sizing.
2.4 DISCHARGE LINES
A. The proper design of discharge lines minimizes refrigerant pressure drop since high
pressure losses increase the required compressor horsepower per ton of refrigeration.
B. A discharge check-valve at the bottom of a vertical riser will prevent oil (and liquid
refrigerant) from draining back to the compressor during the off-cycle. A check valve may
befactoryoreldsupplied.
C. A reverse trap should be installed at the top of all vertical risers. The top of the reverse
trap should be the highest point in the discharge line and should have an access valve
installed to allow the reclamation of non-condensible gas from the system.

2.5 CONDENSATE LINES
A. The condensate line must be designed to allow free drainage of refrigerant from the
condenser coil to the receiver.
2.6 ELECTRICAL WIRING
A. All wiring and connections to the air-cooled condenser must be made in accordance with
the National Electrical Code and all local codes and regulations.
B. Any wiring diagrams shown are basic and do no necessarily include electrical
componentswhichmustbeeldsupplied.

OPERATION
3.1 SYSTEM START-UP CHECKS
A. Check the electrical characteristics of all components to be sure they agree with the
power supply.
B. Check tightness of all fans and motor mounts.
C. Check tightness of all electrical connections.
D. Upon start-up, check fans for correct rotation. Air is drawing through the condenser coil.
To change rotation on 3 phase units reverse any two (2) motor leads.
E. All system piping must be thoroughly leak checked before a refrigerant charge is
introduced.
3.2 MAINTENANCE
A. The most effective way to prevent potential problems with this air-cooled condenser is to
haveasemi-annualinspectionpreformedbyaqualiedrefrigerationservicemechanic.
WARNING: Do not connect the unit to a voltage supply not equal to the unit’s voltage
requirements as specified on the unit’s data plate. Use of incorrect voltage will void the unit’s
warranty and cause a significant hazard that may result in serious personal injury and unit
damage.
WARNING: Electric Shock Hazard. High Voltage is present in the electrical cabinet.
Disconnect power before servicing. Follow all facility lock-out tag-out procedures.
WARNING: Check that all electrical connections are tight before starting.
Disconnect power before servicing. Follow all facility lock-out tag-out procedures.
WARNING: This equipment contains hazardous voltages that can cause severe injury or
death. Disconnect and lock out incoming power before installing or servicing the equipment.
WARNING: Follow all Factory operations procedures. Failure to do so may create a
hazardous operating condition which may result in serious operator injury and/or unit damage.

potential hazardous risk.
C. Check the following :
1. Check all electrical components for damage. Tighten any loose connections.
2. Check settings of all controls to ensure proper operation.
3. Look for any wear on wires or refrigerant lines that may have been caused by
excessive vibrations or rubbing on metal parts.
4. Fan motors are permanently lubricate and require only visual inspection.
