System Health Check / Maintenance

NOTE: These are checks that should be carried out regularly to ensure that your Dimplex product
performs at its best.

5.1 Heat pump:

• Is the fan grille clear from debris? - Visual check
• Is the tray clear from debris and water flowing freely? - Visual check
• Is the condensate drain clear from debris?
• Is the evaporator coil clean and free from damage? E.g. flattened fins
• Are all of the outer panels secure?

5.2 Electrical:

• Is the power cable firmly fixed?
• Is the earth wire connection secure?
• Is the supply voltage correct?

5.3 Hydraulics:

• Is the system correctly pressurized?
• Are there any water leaks in the system? Is the required pressure holding?
• Is the strainer on the return pipe clear of debris?
See section 4.1.3 for details on isolating and cleaning the strainer.

5.4 Indoor settings:

• Are the set temperatures and heating times suitable for the occupants?
• Is the building warm enough for the occupants or does the heating curve need to be adjusted?
NOTE: It is recommended that the strainer is checked and cleaned 24 hours after commissioning, and
each time the system is modified or has service work carried out thereafter.
