Daikin Screw Chiller AWV024

Enter the Discharge Temperature

Enter the Saturated Oil Temperature

Oil sump check is set to Ready when: Discharge Temperature > Saturated Oil Temperature + 5°C

Oil sump check is set to Not Ready when: Discharge Temperature < Saturated Oil Temperature + 4.5°C

Warning: After the compressor has been pumped down and isolated, the oil contained inside the filter housing will remain hot enough to cause burns for some time afterwards. Always allow sufficient time for the oil to cool down so that it is cool enough not to be a danger when drained off (less than 35°C is recommended). Severe injury from burns can result.

Electrical supply to the control panels and compressor motor terminal isolated?

Oil filter assembly components are: - Oil Filter – 250mm - Oil Filter Housing Cover - O-Ring – 89.5x3 - O-Ring – 76.1x3.4 - (6) M8 Bolts

Unscrew and remove two hex head side cover bolts 180° apart. Insert M8 guide studs into the vacant holes.

Remove remaining bolts and oil filter housing cover.

Pull the oil filter off of the spigot and withdraw the oil filter from the housing and clean the housing.

Clean oil filter housing cover plate and all other components.

Warning: This cleaning procedure requires trained personnel with PPE!

Quarterly cleaning is essential to extend the life of an epoxy coated coil and is required to maintain warranty coverage.

Coil cleaned with an approved coil cleaner?

Chloride remover used to remove soluble salts and revitalize the unit?

Warning: Use caution when applying coil cleaners. They can contain potentially harmful chemicals. Wear breathing apparatus and protective clothing.

Barrier removed prior to application of CHLOR*RID DTS?

CHLOR*RID DTS applied uniformly across the substrate?

- Water strainer installed on evaporator, 0.125” (3.2mm) or smaller perforations

- Water System filled, flushed and vented

- Pumps installed and operational (rotation checked, strainers cleaned)

- Controls operational (3-way valves, face/bypass dampers, bypass valves, etc.)

- Water system operated and tested; flow meets unit design requirements

- Flow switch installed and wired

NOTICE: Daikin Applied service personnel or factory authorized service agency must perform initial startup in order to activate warranty. Return the “Screw Compressor Equipment Warranty Form” within 10 working days to Daikin Applied as instructed on the form to obtain full warranty benefits.

CAUTION: Most relays and terminals in the unit control center are powered when S1 is closed and the control circuit disconnect is on. Therefore, do not close S1 until ready for startup or the unit may start unintentionally and possibly cause equipment damage.

Inspect the chiller to ensure no components became loose or damaged during shipping or installation, including leak test and wiring check.

Double check that the discharge shutoff valve and the optional compressor suction butterfly valves are open.

Check that the manual liquid line shutoff valves at the outlet of the subcooler coils are open.

Check the leaving chilled water temperature set point on the MicroTech® III controller to be sure it is set at the desired chilled water temperature.

Start the auxiliary equipment for the installation by turning on the time clock, and/or remote on/off switch, and chilled water pump.

Check to see that pumpdown switches Q1 and Q2 are in the “Pumpdown and Stop” (open) position. Throw the S1 switch to the “Auto” position.

Under the “Control Mode” menu of the keypad, place the unit into the automatic Cool Mode.
