* Oil sight glass & Rotalock features Customers can be confident that ZB scroll compressors are coming from Emerson Climate Technologies experience of over 80 million scroll compressors. ZB scroll compressors are manufactured in our scroll factories in Suzhou, China and Rayong, Thailand. To our customers, this gives additional value by lower inventory and reduced shipping cost.
Series Description of Features Dual Compliance Unloaded Start Compliance means sealing between the orbiting and fixed scroll The scroll sets separate at the instant of compressor shutdown. This involutes. Dual compliance means the sealing is on both the axial and allows the scroll set internal pressures to equalize on compressor radial directions.

Series Application Guide 1. Scroll Compression process Compression in the scroll is created by The open passages are sealed off As the spiral continues to orbit, the interaction of an orbiting spiral and as gas is drawn into the spiral. the gas is compressed into two a stationary spiral.
Series Application Guide 2. Compressor Internal Protections 2.2 Internal Scroll Temperature Protection Events such as loss of charge, condenser fan failure, or low side charging 2.1 Internal Pressure Relief Valve: with inadequate pressure will cause the discharge gas to quickly rise. Models ZB15- ZB48 has internal pressure relief valve, which open at a Excessively high discharge gas temperatures would affect the scroll discharge to suction differential pressure of 375 to 450 psi.
Series Application Guide Models ZB95KQ/E and ZB114KQ/E with motor protection code “W” use 3.2 Rotation Direction of Three Phase Scroll Compressors a combination of sensors and an electronic module (INT69SU) for motor Scroll compressors will only compress in one rotational direction. protection.
A separate form may be requested (Form 93-11) other compressors. Due to the different thermal properties of steel which lists Emerson approved lubricants that may be used to recharge and copper, brazing procedures may have to be changed from those these compressors or if the addition of oil is required.
Series Application Guide 3.8 Special handling consideration for ZB58-ZB114 Three-phase models ZB58- ZB114 model compressors have the suction fitting located low on ZB15–ZB48- outdoor only the shell. Due to this, its recommended to leave the suction connection Crankcase heaters are required on three phase compressors where the plug in place until the compressor is set into the unit.
This compressor into the low side on shut down. Emerson recommends that phenomenon can occur with any compressor when the motor is the cut out setting of the pump-down pressure control be set no more immersed in refrigerant and does not present any safety issue.
Series Application Guide Proper indoor and outdoor blower/fan operation should be verified. • Determine the control voltage by using a voltmeter and then measure the voltage across the M1-M2 contacts: With service gauges connected to suction and discharge pressure If the measured voltage is equal to the control volts then the fittings, turn on the compressor.
S1-S2 then the module is faulty and should be replaced. Figure 2 Table 4 Technical Data Summary Of Module New Installations Emerson P/N 071-0641-00 • The copper-coated steel suction and discharge tubes on scroll Manufacturer P/N Kriwan 69SU Kriwan 69SU...
