Scroll Compressors for Commercial Refrigeration

CBP and LBP Commercial Refrigeration ApplicationsTecumseh’s new VSC Series Scroll Compressor has been designed to replace Original Equipment compressors used today on 2 to 10 ton R404A/R507 commercial refrigeration applications. The VSC scroll complements our current offering of 1-1/2 to 5 ton refrigeration reciprocating compressors, giving Tecumseh Authorized Wholesalers a single source for commercial refrigeration replacement compressors.

VSC Series Scroll refrigeration compressors are considered “Universal” replacements since they have the standard mounting footprint, overall height, rotolock connections, orientation and performance characteristics of competitive models.

•UNIVERSAL REPLACEMENT FOR ORIGINAL EQUIPMENT COMPRESSORSStandard mounting footprint, overall height and rotolock connection size/orientation. Meets or exceeds performance characteristics of competitive models.

•ENERGy SAVINGS High efficiency motor and optimized scroll design combine to reduce energy consumption and deliver high capacity for commercial refrigeration applications. Vapor injection (LBP models) boosts cooling capacity.

•QUIETEST SCROLL ON ThE MARkETLow sound is a result of smooth and continuous compression combined with the absence of suction/discharge valves.

•hIGh RELIAbILITyBuilt-in reliability due to scroll design and engineered bearings. Thermal fault protection contributes to excellent reliablity.

• Don’t expose the compressor and the packaging to rain or corrosive atmosphere.

• Never use the compressor in a flammable atmosphere.

• Mount the compressor on a horizontal flat surface with less than 7° slope.

• Verify that the power supply corresponds to the compressor motor characteristics.

• Use clean and dehydrated refrigeration-grade copper tubes and silver alloy brazing material.

• Use clean and dehydrated system components.

• The piping connected to the compressor must be flexible in 3 dimensions to dampen vibrations.

• The compressor must always be mounted with the rubber grommets supplied with the compressor.

• Slowly release the nitrogen holding charge through the discharge and suction ports.

• Connect the compressor to the system as soon as possible to avoid oil contamination from ambient moisture.

• Avoid material entering into the system while cutting tubes. Never drill holes where burrs cannot be removed.

• Do not exceed the maximum torque for rotolock connections (see below).

• Tightening torque of rotolock connections: 1'' = 59 ft-lb ± 15 1 1/4'' = 66 ft-lb ± 15 1 3/4'' = 81 ft-lb ± 15

• Connect the required safety and control devices. When the schrader port, if any, is used, remove the internal valve.

Important!

The VSC Scroll compressor must only be used for its

designed purpose(s) and within its scope of application

(refer to operating limits). Consult application guidelines

and datasheet(s) available at www.tecumseh.com

Leak detection• Never pressurize the refrigeration system with oxygen or dry air. This could cause fire or explosion.

• Do not use leak detection dye.

• Perform a leak detection test on the complete system.

• The low side test pressure must not exceed 450 psig.

• When a leak is discovered, repair the leak and repeat the leak detection.

Vacuum dehydration

• Never use the compressor to evacuate the system.

• Connect a vacuum pump to both the LP & HP sides.

• Pull down the system under a vacuum of 500 microns Hg.

• Do not use a megohmmeter nor apply power to the compressor while it is under vacuum as this may cause damage.

Electrical connections

• Switch off and isolate the main power supply.

• All electrical components must be selected as per local standards and compressor requirements.

• Refer to page 4 for electrical connections details. For three-phase applications, the terminals are labeled T1, T2, and

T3. For single-phase applications the terminals are labeled C (common), S (start), and R (run).

• Tecumseh scroll compressors will only compress gas while rotating counter-clockwise (when viewed from the

compressor top). Since single-phase motors will start and run in only one direction, reverse rotation is not a major

consideration. Three-phase motors, however, will start and run in either direction, depending on the phase angles

of the supplied power. Care must be taken during installation to ensure that the compressor operates in the correct

direction.

• Use #10 - 32 screws and ¼” ring terminals for the power connection with ring connect screw terminal (C type).

Fasten with 26.6 in. lb torque.

• Use ¼” tabs for quick connect spade terminals (P type).

• Use a self tapping screw to connect the compressor to ground.

Charging the system

• Keep the compressor switched off.

• Keep the refrigerant charge below the indicated charge limits if possible.

Above this limit; protect the compressor against liquid flood-back by using

a pump-down cycle or suction line accumulator.

• Never leave the refrigerant filling cylinder connected to the circuit.

Verification before commissioning

Use safety devices such as safety pressure switch and mechanical relief

valve in compliance with both generally and locally applicable regulations and safety standards. Ensure that they are

operational and properly set.

• Check that the settings of high-pressure switches don’t exceed the maximum

service pressure of any system component.

• A low-pressure switch is recommended to avoid low pressure operation.

(Please refer to the Minimum Setting table to the right).

• Verify that all electrical connections are properly fastened and in compliance

with local regulations.

• When a crankcase heater is required, it must be energized at least 24 hours

before initial start-up and start-up after prolonged shutdown.

• Tighten rotolock nut to 66 ± 15 ft-lb.

Startup• Never start the compressor without the proper refrigerant charge.

• Do not provide electrical power to the compresor unless suction and discharge service valves are open, if installed.

• Energize the compressor. It must start promptly. If the compressor does not start, check wiring conformity and

voltage at the compressor terminals.

• Reverse rotation can be detected by following phenomena; excessive noise, no pressure differential

between suction and discharge, and line warming rather than immediate cooling. A service technician should be

present at initial start-up to verify that supply power is properly phased and that the compressor is rotating in the

correct direction. VSC-series Scroll compressors are designed to operate for a maximum of 150 hours in reverse,

but as a reverse rotation situation can go unnoticed for longer periods, phase monitors are recommended. For

compressor models VSC9548Z and larger, phase monitors are required for all applications. Tecumseh recommends ©2014 Tecumseh Products Company. All Rights Reserved.

phase protection for residential compressors.

• If the internal overload protector trips out, it must cool down to 140°F (60°C) to reset. Depending on ambient

temperature, this may take up to several hours.

Check with running compressor

• Check current draw and voltage. Measurement of amps and volts during running conditions must be taken at other

points in the power supply, not in the compressor electrical box.

• Check suction superheat to reduce risk of slugging.

• Observe the oil level in the sight glass (if provided) for about 60 minutes to ensure proper oil return to the compressor

• Respect the operating limits.

• Check all tubes for abnormal vibration. Movements in excess of 1/16 in (1.5 mm) require corrective measures such as

tube brackets.

• When needed, additional refrigerant in liquid phase may be added in the low-pressure side as far as possible from the

compressor. The compressor must be operating during this process.

• Do not overcharge the system.

• Never release refrigerant to the atmosphere.

• Before leaving the installation site, carry out a general installation inspection regarding cleanliness, noise and leak

detection.

• Record type and amount of refrigerant charge as well as operating conditions as a reference for future inspections.

Maintenance

Internal pressure and surface temperature are dangerous and may cause permanent injury. Maintenance operators and

installers require appropriate skills and tools. Tubing temperature may exceed 212°F (100°C) and can cause severe burns.

Ensure that periodic service inspections to ensure system reliability and as required by local regulations are performed.

To prevent system related compressor problems, following periodic maintenance is recommended:

• Verify that safety devices are operational and properly set.

• Ensure that the system is leak tight.

• Check the compressor current draw.


• Confirm that the system is operating in a way consistent with previous maintenance records and ambient conditions.

• Check that all electrical connections are still adequately fastened.

• Keep the compressor clean and verify the absence of rust and oxidation on the compressor shell, tubes and electrical

connections.

• Acid / moisture content in system and oil should be checked regularly.

WarrantyAlways provide the model number and serial number with any product warranty claim.

The product warranty may be void in the following cases:

• Absence of compressor nameplate/label.

• External modifications; in particular, drilling, welding, broken feet and shock marks.

• Compressor opened or returned unsealed.

• Rust, water or leak detection dye inside the compressor. Do not overcharge the system.

• Use of a refrigerant or lubricant not approved by Tecumseh.

• Any deviation from recommended instructions pertaining to installation, application or maintenance.

• Use in mobile applications.

• Use in explosive atmospheric environment.

• No model number or serial number transmitted with the warranty claim.

with local regulations.

• When a crankcase heater is required, it must be energized at least 24 hours

before initial start-up and start-up after prolonged shutdown.

• Tighten rotolock nut to 66 ± 15 ft-lb.

Startup• Never start the compressor without the proper refrigerant charge.

• Do not provide electrical power to the compresor unless suction and discharge service valves are open, if installed.

• Energize the compressor. It must start promptly. If the compressor does not start, check wiring conformity and

voltage at the compressor terminals.

• Reverse rotation can be detected by following phenomena; excessive noise, no pressure differential

between suction and discharge, and line warming rather than immediate cooling. A service technician should be

present at initial start-up to verify that supply power is properly phased and that the compressor is rotating in the

correct direction. VSC-series Scroll compressors are designed to operate for a maximum of 150 hours in reverse,

but as a reverse rotation situation can go unnoticed for longer periods, phase monitors are recommended. For

compressor models VSC9548Z and larger, phase monitors are required for all applications. Tecumseh recommends ©2014 Tecumseh Products Company. All Rights Reserved.

phase protection for residential compressors.

• If the internal overload protector trips out, it must cool down to 140°F (60°C) to reset. Depending on ambient

temperature, this may take up to several hours.

Check with running compressor

• Check current draw and voltage. Measurement of amps and volts during running conditions must be taken at other

points in the power supply, not in the compressor electrical box.

• Check suction superheat to reduce risk of slugging.

• Observe the oil level in the sight glass (if provided) for about 60 minutes to ensure proper oil return to the compressor


• Check all tubes for abnormal vibration. Movements in excess of 1/16 in (1.5 mm) require corrective measures such as

tube brackets.

• When needed, additional refrigerant in liquid phase may be added in the low-pressure side as far as possible from the

compressor. The compressor must be operating during this process.

• Do not overcharge the system.

• Never release refrigerant to the atmosphere.

• Before leaving the installation site, carry out a general installation inspection regarding cleanliness, noise and leak

detection.

• Record type and amount of refrigerant charge as well as operating conditions as a reference for future inspections.

Maintenance

Internal pressure and surface temperature are dangerous and may cause permanent injury. Maintenance operators and

installers require appropriate skills and tools. Tubing temperature may exceed 212°F (100°C) and can cause severe burns.

Ensure that periodic service inspections to ensure system reliability and as required by local regulations are performed.

To prevent system related compressor problems, following periodic maintenance is recommended:

• Verify that safety devices are operational and properly set.

• Ensure that the system is leak tight.

• Check the compressor current draw.


• Confirm that the system is operating in a way consistent with previous maintenance records and ambient conditions.

• Check that all electrical connections are still adequately fastened.

• Keep the compressor clean and verify the absence of rust and oxidation on the compressor shell, tubes and electrical

connections.

• Acid / moisture content in system and oil should be checked regularly.

WarrantyAlways provide the model number and serial number with any product warranty claim.

The product warranty may be void in the following cases:

• Absence of compressor nameplate/label.

• External modifications; in particular, drilling, welding, broken feet and shock marks.

• Compressor opened or returned unsealed.

• Rust, water or leak detection dye inside the compressor. Do not overcharge the system.

• Use of a refrigerant or lubricant not approved by Tecumseh.

• Any deviation from recommended instructions pertaining to installation, application or maintenance.

• Use in mobile applications.

• Use in explosive atmospheric environment.

• No model number or serial number transmitted with the warranty claim.

DisposalTecumseh recommends that compressors and compressor oil should be recycled by a suitable company at its site.
