Daikin Screw Chiller AWV010

Annual (or spring startup) operations include all weekly and monthly operations.

- Inspect thermal insulation for integrity

Electrical ( * including the VFDs):

- Check contactors for pitting, replace as required

- Check terminals for tightness, tighten as necessary

DANGER: Electric equipment can cause electric shock which will cause severe personal injury or death. Turn off, lock out and tag all power before continuing with following service. Panels can have more than one power source.

CAUTION: Periodically check electrical terminals for tightness and tighten as required. Always use a backup wrench when tightening electrical terminals.

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.

Before reassembly, remove any paint from joint faces. Inspect parts individually for damage and ensure they are completely clean before laying them out on a clean surface in a logical order ready for reassembly.

Use fresh refrigerant oil to lubricate parts during reassembly.

Install new O-rings on the oil filter housing cover.

Insert new oil filter into the housing, ensuring the filter sits tightly on the sealing spigot.

Replace the oil filter housing cover.

Evacuate air and non-condensibles before valving refrigerant back into the compressor.

Warning: The fan motor bearings are permanently lubricated. No further lubrication is required.

Warning: Excessive fan motor bearing noise is an indication of a potential bearing failure.

CAUTION: POE oil must be handled carefully using proper protective equipment (gloves, eye protection, etc.).

CAUTION: The oil must not come into contact with certain polymers (e.g. PVC) as it may absorb moisture from this material.

CAUTION: Do not use oil or refrigerant additives to the system.
