47EcoBreeze System Operation and Maintenance

Inspecting the Heat Exchangers. Inspect heat exchangers Module by Module. Remove power

from the Module to be inspected. Be certain that the branch circuit feeding the Module is turned

off. Open the access panels. Remove one section of mist eliminators from the upper portion of

the Module. Inspect the top of the heat exchangers for buildup of mineral deposits, dirt, or

microbial contamination. If any evidence of contamination is found, the IEC core may need to

be removed to perform a thorough inspection of the IEC core tubes. If additional contamination

is found on the IEC core tubes, the water collectors should be cleaned.

Water pulse power treatment system. Inspect the AC power supply for visible damage that

might affect water treatment system safety and operation. This visible inspection should ensure

that no wires have been cut or are exposed.

• Inspect the umbilical cable for visible damage that might affect the safety and operation

of the water treatment system. This visual inspection should ensure that no wires have

been cut or are exposed.

• Inspect the umbilical cable connectors at both the signal generator and treatment Module

umbilical cable for corroded or damaged pins.

• Inspect the treatment Module ventilation ports to verify that they are clear.

• Inspect the signal generator to ensure that it is firmly secured.

• Inspect the signal generator fan filters and ventilation exhaust/filter to verify that they are

clear.

• Cleaning: In a dusty environment, the ventilation filters of the signal generator and the

ventilation ports on the treatment Module may need to be periodically cleaned. If for any

reason the outward surface of the signal generator requires cleaning, clean the outside

surface with a damp, clean cloth. Wipe clean with a soft cloth. Let it air dry.

Electrical

Check the electrical panels and controls: Turn off the main disconnect on the control panel.

• Make a general check for possible problems: frayed wires, loose relays, overheated

parts, loose terminal connections, etc.

• The access door is secured with bolts to prevent unauthorized access. Replace the bolts

after installation or servicing. The control panel door has an electrical disconnect to shut

off power to the entire unit.

• Check that the wires are color-coded or numbered at both ends and that the terminal

block connection points are numbered. These markings correspond with the electrical

diagram provided in the operating and maintenance manual.

• Check for any signs of damage.

• Check the location and mounting of the user interface. Check the operation of the display

and key pad.
