Step 2 — Rig and Place Unit

RIGGING — These units are designed for overhead rig ging and this method should be used. Lifting holes are pro vided in the frame base rails which are marked for rigging (see rigging label on the unit). It is recommended that field supplied pipes of sufficient length that extend beyond the frame are passed through the holes. Attach cables, chains, or straps to both ends of the pipes. Use spreader bars or a frame to keep the cables, chains, or straps clear of the unit sides. All cables should run to a central suspension point so that the angle from the horizontal is not less than 45 degrees. See Fig. 2 and Table 1 for weight distribution information. Standard coil protection packaging will pro vide some protection to the unit. Raise and set the unit down carefully.

Domestic Units With No Overhead Rigging— Standard con denser packaging consists of coil protection only. Skids are not provided as part of the standard packaging. If overhead rigging is not available at the jobsite, place the unit on a skid or pad by using jacks at the rigging points before drag ging or rolling. When rolling, use a minimum of 3 rollers. When dragging, pull the pad or skid. Do not apply pressure

to the unit. Raise from above to lift off the pad or skid

when in final position. See rigging section above for more information.

Export and Domestic Units With Skids— All export units are mounted on skids with vertical coil protection. Leave the unit on the skid until it is in the final position. While on

the skid, the unit can be rolled, dragged or forked; do not

apply force to the unit. Use a minimum of 3 rollers when

rolling, and raise from above to remove the skid when unit is in the final position. See rigging procedure above for more information.

A CAUTION

Do not forklift these units unless attached to a skid de signed for forklifting; damage to unit may occur. If uti lizing a packaging option which includes a skid, the forklift truck must have at least a 60-in. (1524 mm) fork.

PLACING THE UNIT — Locate the condenser where an adequate supply of inlet outdoor air is available. Do not lo cate where the possibility of air recirculation exists, such as under a roof overhang. Also, locate the condenser in an area free from airborne dirt or other foreign material which could clog the condenser coils. Refer to Fig. 3 and 4 for airflow clearances. For multiple units, allow 8 ft (2440 mm) separation between units for airflow and service. Placement area must be level and strong enough to support operating weight of the unit (Fig. 2 and Table 1). It is recommended to bolt unit securely to pad when unit is positioned and lev eled. Fasteners for mounting unit are field supplied. If vi bration isolators are required for a particular installation, refer to the unit weight distribution data table and diagram below to help select the proper isolators.

Step 3 — Complete Refrigerant Piping

GENERAL — All field leak and pressure testing should be in accordance with local code requirements. If a local code does not exist, use ASHRAE (American Society of Heat ing, Refrigeration and Air Conditioning Engineers) Stan dard 15, Safety Code for Mechanical Refrigeration.

For leak testing procedures, refer to the Carrier’s

“Refrigerant Service Techniques” Book, Form SM-IA.

For any parts that need to be removed, use a mini tubing cutter. Perform phos-copper brazing on all field-made con nections while protecting adjacent joints from heat.

Install or replace filter-drier(s). BEFORE CHARGING THE SYSTEM, INSTALL OR REPLACE THE FILTERDRIER(S) CONNECTED TO THE LIQUID LINE WITHIN THE INDOOR UNIT(S) TO PREVENT CONTAMINA TION WITHIN THE SYSTEM.

COIL REFRIGERANT PIPING INSTALLATION - Hot gas and liquid connections are located on the same end and are capped from the factory with a heat shrink-type cap, which provides a clean joint for field piping. The coil cir cuiting is designed to provide several selections of coil splits to satisfy various applications (See Table 2), with piping connections made in the field. In all cases where circuits are field connected, the piping connections should be made within the unit cabinet. The hot gas lines should enter and the liquid lines should leave the condenser at the header end of the unit.

As a standard item, a tubing package for headering, in cluding two fan cycle pressure switches (FCPSs) and hard ware is provided for the 100, 50/50, and 67/33% typical condenser coil circuiting options. The tubing also provides the ports for easy FCPS installations. The ports come with a 1/4 in. male flare fitting and check valve for each FCPS replacement. Tubing and FCPSs are field installed regard less of circuiting. Tubing packages are not offered for the

33/33/33% and 33/33/17/17% coil circuiting options; tub ing for these coil circuit options must be field fabricated and installed. See Fig. 5 and 6 for tubing package contents.

NOTE: 67/33, 33/33/33 and 33/33/17/17 represent average coil split combinations. Refer to sections below for actual values for your particular coil split combination.

IMPORTANT: With the 67/33, 33/33/33, and 33/33/

17/17% capacity split options, 3 or 4 FCPSs are used. For these applications, an accessory fan control kit is required. See accessory installation instructions for more information.

Figure 7 shows a typical piping application for a condenser with a multiple-split system. Figure 8 shows the typical field piping arrangements for the 09DK units. See Fig. 9 for coil connection details. Figures 10 and 11 show typical factory supplied coil circuiting and typical field installed 67/33% coil split circuiting respectively.

TUBING PACKAGE INSTALLATION - Before install ing, inspect the package contents. If any parts are missing or damaged, file a claim with the shipping company and notify your Carrier representative. A field supplied 3/8-in.

conduit (Greenfield conduit recommended) is required

according to UL/CSA (Underwriters’ Laboratories/ Canadian Standards Association) code for the FCPS field wiring. Field supplied 3/8-in. conduit connectors are re quired for connection to the junction box.

100% Coil Circuiting Applications: 054. 064 Units

1. Piping — Refer to Fig. 9 and 12 for field piping details

for 100% coil circuiting. Note that tubes 15 and 22 require cut on the longer leg of the tube. Two 7/8-in. OD tubes, approximately 3 in. (76.2 mm) long, must be cut from the remaining tubes (tubes 21, 23, or 25) and brazed between the tees (item 8) and coil header stubs. The remaining tubes are not used in this application and may be discarded.

2. Install Fan Cycle Pressure Switches and Clamps — Braze 2 valve core bodies (item 5) to designated hole locations on tubes 19 and 22.

2. Install Fan Cycle Pressure Switches and Clamps — Four FCPSs should be used. Locate holes, valve core assem blies, and FCPS’s 1, 2, 3, and 4 at the specified locations. See Fig. 8. Insert valve cores into valve core bodies by threading into place and tightening to 1.5 to 3 in.-lb (169.5 to 339 mN-m). The additional two FCPSs and valve core assemblies are provided with the accessory fan control kit. Cut the 3/8-in. field-supplied FCPS conduit at a desired length to fit between each FCPS location and the junction box on the unit. See Fig. 11 for typical conduit installation. Feed FCPS wires through each conduit and secure at the switch by utilizing each conduit connector. See Fig. 13. Secure the conduit at the junction box with 3/8-in. field-supplied conduit connectors. Wire the FCPSs according to Fig. 14 and 18. Note that FCPS2 and 4 and FCPSl and 3 are wired in parallel. Fans 3 and 4 are being shared by two different refrigeration circuits. If either refrigeration circuit needs the fan to be on, it will be on. Clamp all lines to brackets sup plied on the unit.

REFRIGERANT LINE SIZING - Sizing depends on length of lines between various sections of the refrigerant system. See Fig. 9 for coil connection details. Consider the amount of liquid lift and drop in the system as well as proper com pressor oil return. See Liquid Lift section for more infor mation. Consult Carrier System Design Manual, Part 3, or Carrier E20-II Refrigerant Piping Computer Program for proper piping sizes and design

LIQUID SHUTOFF VALVE AND SIGHT GLASS - A

shutoff valve is not supplied with 09DK condensers. It is

strongly recommended that a full line size liquid shutoff valve be field supplied near condenser to allow for servic ing parts of the refrigerant circuit A field-supplied mois ture indicating sight glass is recommended for use in charg

ing and servicing the system. Refer to Fig. 7. PRESSURE RELIEF - The ASHRAE Standard 15, Safety

Code for Mechanical Refrigeration states; “Every refriger

ating system shall be protected by a pressure relief device

or some other means designed to safely relieve pressure due

to fire or other abnormal conditions ” Since 09DK con

densers do not have pressure relief devices, one must be

field supplied and installed just before the liquid line ser

vice valve. (See Fig. 7.) When the split coil is used with

multiple systems, each system must have its own pressure

relief.

Procedure for Using the Refrigerant Receiver — See Fig. 24.

1. During normal operation — Valve A is open and valves B and C are closed. Receiver is isolated from the system.

2. For servicing — Valves A and C are closed and valve B is open. Run unit until all the refrigerant is in the re ceiver and then close valve B. Unit is now ready for ser vicing.

3. To resume operation — Leave valve A closed and open valves B and C. Run unit until the stored refrigerant is drawn into the system. To completely remove the re frigerant from the receiver, throttle valve B while noting condition of refrigerant in the liquid line sight glass; also, watch the suction pressure. A sudden surge of bubbles in the sight glass and a rapid decrease in suction pres sure indicates that all the refrigerant has been withdrawn from the receiver. Immediately close valves B and C and then open valve A. The unit should now be ready for normal operation, with the receiver isolated from the

system. The system should be charged to a clear sight

glass when under normal operation.

LIQUID LIFT — Amount of liquid lift available before re frigerant flashing occurs depends on amount of liquid sub cooling in the system.

All 09DK condensers have positive subcooling when ap plied with optimum charge. With subcooling, it is possible to overcome an appreciable friction drop and/or static head

(due to elevation of the liquid metering device above the

condenser).

When 09DK condensers are applied with minimum charge,

no positive subcooling in condenser is realized; therefore, if subcooling is required it must be obtained by external means such as a liquid suction interchanger.

The average amount of liquid lift available is shown in Table 3 for refrigerants R-22, R-502, and R-134A. Avail

able subcooling is greatly reduced when R-12 and R-500 are used in these units. It is recommended that the evapo rator be at the same level as the condenser, or lower.

1/4 SAE FLARE WITH

56 (14 2) HEX

REFRIGERANT RECEIVER — A refrigerant receiver is

not furnished with 09DK condensers and is not recom

mended for normal applications as its use will be detrimen tal to the desired effects of subcooling. However, if a par ticular application requires a receiver to increase refrigerant holding capacity of the condenser, a receiver can be used. When a receiver is to be used year-round, it should be in stalled indoors. Carrier recommends the following installa tion in such a case (see Fig 24): locate valves on each side of the receiver so receiver may be isolated from system for normal operation.

Example: Supply voltage is 240-3-60.

AB = 243 V BC = 236 V AC = 238 V

Average Voltage

243 -F 236 -f 238

^ 717

= 239 V

Determine maximum deviation from average voltage:

(AB) 243 - 239 = 4 V (BC) 239 - 236 = 3 V (AC) 239 - 238 = 1 V

Maximum deviation is then 4 v. To determine the percent voltage imbalance:

% Voltage Imbalance = 100 x----------

239

= 1.7%

This amount of phase imbalance is satisfactory since it is

below the maximum allowable of 2%.

Step 4 — Complete Electrical Connections

GENERAL — Verify nameplate electrical requirements match available power supply. Voltage at condenser must be within the minimum and maximum shown in Table 4 and phases must be balanced within 2%. Contact local power company for line voltage corrections. Never operate a motor where a phase imbalance in supply voltage is greater than 2%. Use the following formula to determine the percent voltage imbalance:

max voltage deviation

% Voltage _ from average voltage

Imbalance ^ average voltage

IMPORTANT: If supply voltage phase imbalance is more than 2%, contact your local electric utility com pany immediately.

Condenser operation on improper line voltage or exces sive phase imbalance may be considered abuse and any re sulting damage may not be covered by Carrier warranty.

All wiring must be in accordance with local or NEC (National Electrical Code) regulations.

Max imum incoming wire size for each terminal connection on TBl is 2/0, and all power wiring must comply with appli cable local and national codes. Refer to the unit power cir cuit information to determine incoming wire sizes. (See Table 4.) Refer to Table 5 for American and European wire conversion information.

CONTROL CIRCUIT POWER WIRING - Provide a sep arate single phase power source for each control circuit (de pending on the coil refrigerant circuit split), with the re quired overcurrent protection (fuses or circuit breakers). See Table 4 for control circuit overcurrent protection amps.

For field control circuit connections, units are factory wired for a 50/50% capacity split and would utilize terminal blocks 2 and 3 (TB2 and TB3). TB2 will control fans 1, 3, and 5; TB3 will control fans 2, 4, and 6. Fans 5 and 6 are on 074 and 084 units only. If 100% condenser application is re quired, connect the factory supplied jumpers from TB2-1 to TB3-1 and from TB2-2 to TB3-2, and bring incoming con nections to either TB2 or TB3. Factory-punched access holes under the control box are provided for the incoming wires. See Fig. 26 for access hole details. Terminal block connec tions utilize no. 8 screws. Wiring must be class 1, 14 AWG (American Wire Gage) copper conductors only. Power re quired for control circuits is 100 va. See Table 4 for control circuit voltage data.

GENERAL WIRING NOTES

1. Power entry is at one end only.

2. Fan motors are thermally protected. Three-phase motors

are protected against primary single-phasing conditions.

3. Replacement of factory wires must be with appliance

wiring material, rated 105 C, or its equivalent.

4 Factory wiring is in accordance with NEC. Field mod

ifications or additions must be in compliance with all applicable codes.

DESCRIPTION OF CONTROLS - The condenser units utilize a dual voltage control scheme: a 3-phase power cir cuit for the fan system operation and a single-phase control circuit voltage for fan cycling control. The number of con trol circuit voltages will depend on the coil split application used. See head pressure control description in the service section for a detailed description of the controls function.

START-UP

System Evacuation and Dehydration — Refer

to GTAC II, Module 4, “Dehydration for Proper Evacua tion and Dehydration techniques.”

Charging Procedure — Charge to a clear sight glass.

Refer to GTAC II, Module 5 “Charging, Recovery, Recy cling, and Reclamation” for proper charging techniques. Add 10 lbs (4.5 kg) of R-22 over clear sight glass to flood subcooler sections of the condenser coils. This 10 lbs (4.5 kg) is added to the total unit charge, and must be pro portioned by the percentage of circuits when multiple cir cuits are employed. For example, in Table 2, add .67 x

10 lbs (4.5 kg) (approximately 6.7 lbs [3.0 kg]) for the 67% circuit. Refer to Table 6 for condenser coil refrigerant circuit data.

Check Operation of Condenser Fan Motor Con trols and Rotation of Fans — Rotation should be

clockwise as viewed from top of unit.

A CAUTION

Before starting unit, be sure wire fan guards are secured in place over each fan; personal injury may result.

SERVICE

Cleaning Condenser Coils — Clean coils with a vac

uum cleaner, fresh water, compressed air, or a bristle brush (not wire). Units installed in corrosive environments should have coil cleaning as a part of a planned maintenance sched ule. In this type of application, all accumulations of dirt should be cleaned off the coil.

A CAUTION

Do not use high-pressure water or air. Damage to fins may result.

Condenser Fans — Each fan is supported by a formed

wire mount bolted to the fan deck and covered with a wire guard. The exposed end of the fan motor shaft is protected by grease. If the fan motor must be removed for service or re placement, be sure to grease fan shaft, and reinstall fan guard. For proper performance, fan should be 7/8 in. (22 mm) be low the top of the venturi on the fan deck for 60 Hz units, and 1/2 in. (13 mm) to top of the fan hub for 50 Hz units. Tighten set screws to 15 ± 1 ft-lbs (20 ±1.3 N-m). Fig ure 27 shows the proper position of the mounted fan.

IMPORTANT: Check for proper fan rotation (clock wise viewed from above). If rotation needs to be re versed on one motor, disconnect main power supply and switch motor leads at the fan contactor. If rota tion needs to be reversed on all motors, disconnect main power supply and switch two leads at TBl.

rated condenser temperature minus entering outdoor-air tem perature) and decreases with decreased temperature differ ence. A drop in entering outdoor-air temperature results in a lower saturated condensing temperature. When outdoorair temperature drops below the minimum temperatures listed in Table 7 for standard units, additional head pressure con trol is required.

Model 09DK units have fully automatic intermediateseason head pressure control through condenser fan cycling using electromechanical fan cycling controls. Standard head

pressure controls will control the 100 and 50/50% con

denser capacity applications. Head pressure can also be con

trolled by fan cycling controls supplemented by the acces

sory Motormaster® III solid-state head pressure controller. See Motormaster III installation instructions for more infor mation. Other circuit split applications (67/33, 33/33/33, 33/33/17/17% capacity splits) will require the accessory fan

control kit which includes a control panel and additional fan cycling pressure switches. See fan control installation

instructions for more information.

In the standard control scheme, fans 1 and 2 will be on

when there is a call for cooling from the respective coil cir cuits. Fans 1 and 2 are non-cycling. On 054 and 064 units, fans 3 and 4 will be controlled by using a fan cycling pres

sure switch on each of the primary coil circuits in response

to condensing pressure. On 074 and 084 units, fans 3 and 4 will also be controlled using a fan cycling pressure switch in each of the primary coil circuits in response to condens ing pressure. Fans 5 and 6 will be controlled by using two air temperature switches, which respond to the outdoor am bient temperature. The air temperature switches are located on the control box shelf. For temperature and pressure set ting details, see Table 8.

With respect to the fan cycling pressure switch control,

fans 3 and 4 are on above 260 ± 15 psig (1793 ± 103 kPa) and off below 160 ± 10 psig (1103 ± 69 kPa). If pressure is rising between 160 psig (1103 kPa) and 260 psig (1793 kPa), fans 3 and 4 are off. If pressure is reducing from 260 psig (1793 kPa) to 160 psig (1103 kPa) fans 3 and 4 are on. With respect to the air temperature switch control on the 074 and 084 condensers, below 70 ± 3° F (21.1 ± 1.7° C) outdoor ambient, fans 5 and 6 are off; above

80 ± 3° F (26.7 ± 1.7° C) fans 5 and 6 are on. Between

70 F (21.1 C) and 80 F, (26.7 C) whether fans 5 and 6 are on or off depends on whether temperature is rising or fall ing. If the temperature is rising from 70 F (21.1 C) to 80 F (26.7 C), fans 5 and 6 are off. If the temperature is falling from 80 F (26.7 C) to 70 F (21.1 C), fans 5 and 6 are on.
