Air-cooled modular chiller unit 50Hz

Troubles

Possible reasons

Solutions

Compressor stops

because of integrate

temperature sensor or air

discharge temperature

protection.

Over high or over low voltage.

Confirm voltage not higher or lower than the rated

voltage 10%.

Over high air expelling pressure or excessive

low air suction pressure.

See “Over high air expelling pressure” and “excessive

low air suction pressure ”.

Component error.

Check the integrated temperature sensor after motor

is cool down.

Compressor stops

because of low pressure

protection.

Filter in front (or rear) of expanding valve is

blocked.

Replace a new filter.

Low voltage switch error.

If the switch is defective, please replace a new one.

Excessive low air suction pressure.

See “Excessive low air suction pressure”.

Abnormal noise comes

from compressor.

Liquid refrigerant flows into compressor from

evaporator result in liquid slugging.

Adjust refrigerant charge volume.

Aging of compressor.

Replace a new compressor.

Compressor can‟t start.

Over current relay trip up, fuse burnt out.

Replace damaged assembly.

Control circuit without power though.

Check the wring of control system.

High voltage or low voltage protection.

Reference to mention in above the parts of air suction

and discharge pressure error.

Coils in contactor are burnt out.

Replace damaged assembly.

Wrong connection of phase sequence.

Re-connect and adjust the any 2 wires among 3

phases.

Water system error and flow type volume

controller short connection.

Check water system.

Error signal delivered from wired controller.

Find out the error type and carry out the

corresponding measure to settle.

Air side heat exchanger

excessive frost.

4-way valve or thermal resistor error.

Check the running state. Replace a new one if

necessary.

Air loop short-circuit.

Settle the short-circuit of air discharge.

With noise.

Fixing screws at panel are loosen.

Fix up all assemblies.
