• Don't allow air, moisture, contaminants to enter compressor.
• Don't charge refrigerant looking at compressor amperes
• Do not bypass LP/HP controls
• Reverse Rotation
Scroll compressors pump in one direction only
Incorrect rotation can be identified by:
-low current, noise, balanced suction and discharge pressure Correct by interchanging
any two phases
Short-term reverse rotation will not damage the compressor
Electrical Tips:
Kindly verify before any Electrical installation if the voltage, frequency and phase of supply satisfy those
required of the unit. Ensure that Operative is following all safety guideline & procedure as mentioned
above while performing Electrical Installation.
• All wiring should be carefully checked & refer wiring diagram (attached inside of the electrical cabinet) to
complete unit control circuit.
• Do not handle high-voltage electrical wiring unless properly trained.
• Check if the Voltage deviation of 10 % is within the specified range mentioned on unit name plate.
• Do not by -pass any electrical safety equipment like MCCB, SPP, Contactor, Overload Relay, timer & other
safety devices.
• Use genuine specified electrical accessories for CDU/Compressor model recommended by Company.
• Check the electrical connections if they are properly attached, secured and properly tightened.
• Make sure all panels are secure and panel screws are properly tightened.
• Check that the ampere draw doesn't exceed the amperage specified on the nameplate.
• Check the phase unbalance if there is a three-phase connection.
• In single phase compressor. Check for neutral connection. It is better to connect Common ( C ) terminal
to the neutral supply.
• Check for proper Earthing/ground. Ensure each component is getting proper supply, no burnt/Chattering
in Connection and is working as intended.
• Do not bypass the crankcase heater connection and its operation sequence (low ambient/
During off cycle).
• If you do not fully understand how to install your product after reading the manufacturer's instructions,
contact our local authorized dealer or technical team for help and do not attempt to install it yourself.

KEEP IN MIND
KHZ Condensing units uses 3-Phase Scroll compressors and can rotate in the wrong
direction when starting. If this happens reverse any two phases (L1 & L3) and start again. So, a Single
phase preventor must require. Always observe the rotation of 3 phase Scroll Compressor by measuring
Current drawn, Compressor pumping and running sound.
