Annual Service Tasks

Mechanical Tasks

(Tick appropriate boxes if applicable)

1 Inspect and clean evaporator fins. Repair damaged fins using a fin comb if required

2 Check visually for signs of oil leaks which may indicate a refrigerant leak (check for leaks if necessary)

3 Check integrity of refrigerant / water pipe work and lagging, repair lagging if required

4 Check system operation

5 Check the antifreeze and if necessary top up the concentration as per manufacturer’s recommendations

6 Check and clean the magnetic particle filter

7 Check system pressure

8 Release any air from the primary/heating systems

Controller Tasks 9 Check for the correct operation and temperature setting of the thermostats 10 Check the operation of the zone valves 11 Check the operation and the timing of the immersion heater
On Completion Check that the whole system is working satisfactorily Mitsubishi Electric recommends that the frequency of maintenance visits to be a maximum of 12 months between inspections. Frequency of maintenance may increase dependent upon the equipment and local water conditions e.g. hard water, scale forming, water containing a high proportion of solids. Failure to maintain the system to the above minimum recommendations could result in the warranty becoming null and void. Please fill in the Service Record sheet to confirm the above tasks have been carried out on the Ecodan outdoor unit.

Service Record
It is recommended that your Ecodan is serviced regularly and that the appropriate Service Interval Record is completed.
