Typical Arrangements Diagram 1 illustrates a typical piping arrangement involving a remote Subcooler condenser located at a higher elevation,as commonly encountered when Diagrams 1 and 2 below show typical subcooler piping. Diagram 1 is the the condenser is on a roof and the compressor and receiver are on grade preferred connection with receiver as it provides maximum subcooling. level or in a basement equipment room. Diagram 2 may be used if the receiver is located far from the condenser. Notes: In this case,the design of the discharge line is very critical. If properly sized 1. All oil traps are to be as short in radius as possible.Common practice is for full load condition,the gas velocity might be too low at reduced loads to fabricate the trap using three 90 degree ells. to carry oil up through the discharge line and condenser coil. Reducing the discharge line size would increase the gas velocity sufficiently at reduced 2. Pressure relief valves are recommended at the condenser for protection load conditions;however,when operating at full load,the line would be of the coil. greatly undersized,and thereby creating an excessive refrigerant pressure 3. A pressure valve at the high point in the discharge line is recommended drop.This condition can be overcome in one of two of the following ways: to aid in removing non-condensables. 1. The discharge line may be properly sized for the desired pressure 4. The placement of a subcooler should be that it does not interfere with drop at full load conditions and an oil separator installed at the normal airflow of the condenser.Increased static of the unit could cause bottom of the trap in the discharge line from the compressor. a decrease in system capacity and fan motor damage. rEpik EWCJJ - - PTLLCM CCNOEfbEY1 DISCHARGE COREEMVER ' CIscKA NE I G"-: 1t • I S.MCDCLER 1 SIECCx.ER • LINNE"A"`E IH�WI G OMONAL A LIVEP221 LIWIC FEL LINE ^ RELIEF LTh€ VALVE TRIP INF TRAP �� ' 1 4 __ MECE IVER ik_cLIv�R Diagram 1 Diagram 2 City&Tower Water Connections In the refrigeration industry"City"and"Tower"are designations of temperature and flow conditions,not applications.The term"City"refers Figure 2.

If adjustments are made during warm ambient conditions,it may not be At condensing pressures above the valve setting,flow enters Port C and possible to adjust the regulator valve as low as desired. Readjustment may leaves Port R.When the condensing pressure falls below the valve setting, be necessary once cooler conditions prevail. the valve modulates to permit discharge gas to enter Port D.Metering discharge gas into the refrigerant flow leaving the condenser produces a higher pressure at the condenser outlet reduces the flow,and causes the level of liquid refrigerant to rise in the condenser.This"flooding"of the condenser with liquid refrigerant reduces the available condensing surface, holding the condensing pressure at the valve setting. Figure 7. Single Valve Flooding Valve Piping Arrangement D Condenser Head Pressure l Control Valve ill C R PR Compressor 0 Receiver CAUTION: Fans closest to the headers should not be cycled on standard temperature or pressure controls.Dramatic temperature and pressure changes at the headers as a result of fan action can result in possible tube failure.Fan motors are designed for continuous duty operation. Fan cycling controls should be adjusted to maintain a minimum of(5)minutes on and(5)minutes off.Short cycling of fans may result in a premature failure of motor and/or fan blade. Compressors operating below+10°F SST must have air flowing over the compressor at all times when the compressor is running. CAUTION: Under no circumstance should all condenser motors be allowed to cycle off on one control.At least one motor shall be wired to operate at all times. Under most circumstances,the condenser motor nearest the inlet header should remain on whenever the compressor is operating. 6 • • Refrigeration Oils* Oil Types With the changes that have taken place in our industry due to the CFC Table 2 below summarizes which oils/lubricants are approved for use in issue,we have reevaluated our lubricants to ensure compatibility with the Copeland compressors. new HFC refrigerants and HCFC interim blends offered by several chemical producers.As a secondary criteria,it is also desirable that any new lubricant Mineral Oils be compatible with the traditional refrigerants such as HCFC-22 or R502.This The BR and Scroll compressors use Sontex 200,a"white oil".This oil is "backward compatibility"has been achieved with the introduction of the not suitable for low temperature applications nor is it available through Polyol ester lubricants. the normal refrigeration wholesalers.

Since moisture levels greater Polyol Ester Lubricants than 100 ppm will results in system corrosion and ultimate failure,it is imperative that compressors,components,containers and the entire system The Mobil EAL ARCTIC 22 CC is the preferred Polyol ester due to unique be kept sealed as much as possible.Lubricants will be packaged in specially additives included in this lubricant.

Copeland compressors are used.These lubricants are compatible with one another and can be mixed. Figure 8.

Oil Level During Copeland's testing of Polyol ester oil,it was found that this lubricant exhibits a greater tendency to introduce oil into the cylinder during flooded start conditions.If allowed to continue,this condition will cause mechanical failure of the compressor. A crankcase heater is required with condensing units and it must be turned on several hours before start-up. Oil level must not exceed 1/4 sight glass. Table 2.

Sizes that are highlighted indicate maximum suction line sizes that should be used for risers. Riser size should not exceed horizontal size. Properly placed suction traps must also be used for adequate oil return. All sizes shown are for 0.D.Type L copper tubing. 2. Suction line sizes selected at pressure drop equivalent to 2-F.Reduce estimate of system capacity accordingly. 3. Recommended liquid line size may increase with reverse cycle hot gas systems. 4.

Be sure they are all tight. b) Observe compressor oil level before start-u p.The oil level should be at or slightly above the 1/4 level of the sight glass.Refer to Table 3 for proper compressor oil. c) Remove upper mounting nuts on the compressor feet. Remove the shipping spacers.Install the neoprene washers onto the compressor feet. Replace the upper mounting nuts and washers,allowing 1/16"space between the mounting nut and the neoprene spacer. d) Check high and low pressure controls,pressure regulating valves, oil pressure safety controls,and all other safety controls,and adjust if necessary. e) Check the room thermostat for normal operation and adjust. 0 Wiring diagrams,instruction bulletins,etc.attached to the condensing units should be read and filed for future reference. g) All fan motors should be checked for proper rotation.Fan motor mounts should be carefully checked for tightness and proper alignment. h) Electric and hot gas evaporator fan motors should be temporarily wired for continuous operation until the room temperature has stabilized. i) Observe system pressures during charging and initial operation. Do not add oil while the system is short of refrigerant unless oil level is dangerously low. j) Continue charging until system has sufficient refrigerant for proper operation.Do not overcharge. Remember that bubbles in a sight glass may be caused by a restriction as well as a shortage of refrigerant. k) Do not leave unit unattended until the system has reached normal operating conditions and the oil charge has been properly adjusted to maintain the oil level between 1/4 and bottom of the sight glass. I) Make sure all Schrader valve caps are in place and tight. m) Make sure ALL service valves are properly back-seated and tighten valve packing if necessary. CAUTION: Extreme care must be taken in starting compressors for the first time after system charging. At this time,all of the oil and most of the refrigerant might be in the compressor creating a condition which could cause compressor damage due to slugging.Activating the crankcase heater for 24 hours prior to start-up is required. If no crankcase heater is present,then directing a 500 watt heat lamp or other safe heat source on the lower shell of the compressor for approximately thirty minutes will be beneficial in eliminating this condition which might never reoccur. WARNING: Scroll compressor is directional dependent.If noisy,change phase of input wiring. 15 I Operational Check Out System Balancing-Compressor Superheat After the system has been charged and has operated for at least two hours at IMPORTANT: normal operating conditions without any indication of malfunction,it should be allowed to operate overnight on automatic controls.Then a thorough In order to obtain the maximum capacity from a system,and to ensure recheck of the entire system operation should be made as follows: trouble-free operation,it is necessary to balance each and every system. a) Check compressor discharge and suction pressures. If not within system design limits,determine why and take corrective action. This is extremely important with any refrigeration system. b) Check liquid line sight glass and expansion valve operation.If The critical value which must be checked is suction superheat. there are indications that more refrigerant is required,leak test Suction superheat should be checked at the compressor as follows: all connections and system components and repair any 1.

For models with plastic cover on timer assembly;re-install cover after adjustment. 11.Suction pressure decreases and the compressor contactor opens when the pressure drops below the cutout setting on the low pressure control.The compressor and condenser fan stop running. 12.This cycle is repeated as many times as necessary to satisfy the room thermostat. 13.Frost starts to form on the evaporator coil and continues to form until the defrost cycle is initiated. Defrost Cycle 1. The defrost cycle starts automatically by the timer at predetermined times.Typical settings are two to four defrost cycles per day for freezers. For heavier frost loads additional settings may be required. 2. Switch"2"to"4"opens in the timer which breaks the circuit to the room thermostat,liquid line solenoid,and evaporator fan motors,allowing the compressor to pump down and shut off. Simultaneously NOTE: switch"1"to"3"closes in the timer allowing current to flow to one side After correcting faulty condition it is essential that the coil and unit be of the defrost heater contactor.When the compressor free of ice before placing unit back on automatic operation. shuts off,an auxiliary contact will send power to the contactor holding coil;thus,energizing the defrost heaters. 3.
