Daikin Applied (UK) Ltd recommends that a minimum of 3 maintenance and inspection visits are carried out per year (1 x Major, 2 x Minor as described below). The following is for example purposes only and is not job specific. The maintenance requirements for each job will depend on the internal equipment installed. Job specific maintenance schedules can be supplied by our projects team.

• Measure supply pre-filter differential pressure
• Change extract pre-filters if applicable
• Measure extract main and pre-filter differential pressure
• Zero pressure gauges
• Check condition of door seals
• Check operation of door handles
• Check free rotation of fan impeller
• Monitor vibration levels on fans / motors
• Check fan belt tension
• Check condition of fan shaft and motor bearings. Lubricate if necessary.
• Check dampers for operation and lubricate if necessary
• Check coils for fin damage and blockage
• Check operation of light switches
• Check operation of cooling coil condensate tray / trap

Major visit

Chiller Start up

The equipment must be started for the first time by an authorised Daikin Applied (UK) Ltd employee or agent; Failure to adhere to this procedure will invalidate the Warranty. It is recommended that the equipment is not started with high chilled water temperatures +25°C. A full load to the chiller should be available when the start-up is commenced, failure to supply this may require additional visits at an additional cost.

Extended shut down

If the equipment is intended to be out of service for an extended period of time (for instance, by way of illustration only, a period in excess of 12 weeks) then the purchaser must consult Daikin Applied (UK) Ltd for the correct procedure.  Failure to do so may invalidate the Warranty.

Maintenance guidelines

Daikin Applied (UK) Ltd recommends that a minimum of 4 maintenance visits are carried out per year (1 Major, 3 Minor as described below); SFG 20 standard maintenance guidelines are not acceptable.  Please note that the extended parts only warranty does not include consumables, which include refrigerant.

Minor visit

A full running log is taken for each circuit, highlighting all superheats, sub cooling, temperatures, pressures, water flows, pressure drops (both refrigeration and water)  The refrigerant circuits should also be tested for leaks and a general report on the condition of the chiller should be taken. At least 2 of the inspections must include electrical tightness checks on all components.

Major visit

In addition to the maintenance procedures carried out on a Minor Visit (as set out above), the filter driers, oil filter, oil charge should be replaced (where applicable) a spectrum analysis of the oil should also be taken (where applicable), the condenser coils should only be cleaned as per Daikin Applied (UK) recommendations defined in the ‘operations and maintenance’ manual; if in doubt please contact the company directly.

Caution: A clear sight glass alone does not mean that the system is properly charged. The purchaser must check system superheats, sub cooling and unit operating pressures regularly.
