for Commercial Refrigeration Installation Instructions

 Part Number:  132-10011 

       

Publication: TR-306  7/14

ELECTRICAL COMPONENTS

 

Use only new electrical components specific  
for this compressor model.

NOTE: The compressor is delivered with a pressurized nitrogen charge (between 4 and 

6 psig). Do not disassemble bolts, plugs, fittings, etc...unless all pressure has been 

relieved from the compressor. Wear protective goggles and work gloves.

Under all circumstances, applicable local safety regulation requirements must be used. 

The compressor must be handled with caution in the vertical position (maximum offset 

from the vertical: 15°).

Never operate compressor without electrical terminal box cover in place and secured.

General Installation Instructions

These instructions pertain to the Tecumseh VSC Series Commercial (LBP) scroll 

compressors used for refrigeration systems. They provide necessary information 

regarding safety and proper usage of this product. 

• 

Handle the compressor with care. Use the dedicated handles in the    

  packaging. Use the compressor lifting lug and use appropriate and safe  

  lifting equipment.

• 

Store and transport the compressor in an upright position. 

• 

Store the compressor between -30°F and 158°F (-35°C and 70°C). 

• 

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
