Daikin Air Cooled Chiller EWFS-TZ-D

Disconnect the unit from power supply.

Wait for the fans to stop completely.

Ensure that the fan blades cannot move for any reason (for example: wind).

If present, remove the ”V” shaped panels.

Remove surface dirt, leaves, fibres, etc. with a vacuum cleaner (preferably with a brush or other soft attachment rather than a metal tube), compressed air blown from the inside out, and/or a soft bristle (not wire!) brush. Do not impact or scrape the coil with the vacuum tube, air nozzle, etc.

The unit must absolutely not be put into operation, even if for a very short period, without having first meticulously checking the following list in its entirety.

This general commissioning checklist can be used as a guideline and reporting template during the commissioning and hand-over to the user.

For more detailed commissioning instructions, please contact the local Daikin Service department or authorized representative of the manufacturer.

- Open all isolation and / or shut-off valves

- Verify that the unit is pressurized with refrigerant in all of its parts before making the connection to the hydraulic circuit.

- Check the oil level in the compressors

- Control wells, thermometers, manometers, controls, etc. installed

Enter the TAN (Total Acid Number)

Sign off on the compressor oil check

Visual inspection of unit for any damage and/or loosening

Visual inspection of components for any signs of overheating

Verify operation of compressor and oil heater

Clean air intake filters of the electrical panel

Check for any refrigerant leakage

Verify filter dryer pressure drop

Verify oil filter pressure drop. Replace the oil filter when the pressure drop across it reaches 2.0 bar.

Check security valves. Check that the cap and the seal have not been tampered with. Check that the drainage connection of the safety valves is not accidentally occluded by foreign objects, rust or ice. Check the manufacturing date on the safety valve and replace it, if necessary, in compliance with the national laws in force.
