Maintenance; General Tips - Dimplex Optimyst CAS500P-RGB-EU Operating Instructions Manual

NOZZLE INSERTS
Nozzle inserts have been supplied and fitted into the nozzle opening. These are used to shape the profile of the flame
effect but can be removed if a different flame profile is preferred. To remove, lift up the 2 small D shaped taps to loosen
the insert, then it can be pulled out.
Alternative blocking inserts have also been supplied to block off sections of the flame. To fit them, first remove the
existing inserts. Break the blocking inserts to the required length and place in the nozzle opening in the desired location.
Ensure they are orientated correctly before pushing down to snap into position. See Fig 26 for further details.

MAINTENANCE

GENERAL TIPS

Only use clean tap water in this appliance. Refer to Water Quality & Cleaning section for details.
Always ensure that the appliance is sitting on a level surface.
If you intend not using the appliance for longer than a week, remove and empty the sump and water tank.
Once installed, never move this appliance or lay on its back, without draining the water from sump.
CLEANING
WARNING: Always press Switch 'A' to the 'OFF' (0) position (Fig 23A) and disconnect from the power supply before
cleaning the fire.
We recommend cleaning the following components once every week, particularly in hard water areas:
Tank cap and seal (Fig 11/37), Nozzle (Fig 29), Transducer (Fig 30), Sump (Fig 31) & Air filter (Fig 32).
For general cleaning use a soft clean duster – never use abrasive cleaners.
To remove any accumulation of dust or fluff, the soft brush attachment of a vacuum cleaner should occasionally be used.

There are two orange clips holding down the nozzle on the sump; one on the left and one on the right hand side of
the nozzle. On the left side, press in the clip with one hand and with the other lift the nozzle out of the clip. Repeat
this for the right side (Fig 28). The nozzle can now be lifted up and placed aside (Fig 29).

CHANGING THE SPONGE ABSORPTION VALVE PAD
A sponge absorption valve has been fitted to the appliance as an additional safety measure (Fig 34) to prevent leaks.
In the unlikely event that a leak occurs inside the product, the valve will prevent water from flowing to the product. When
the valve has been activated, the pad within the valve absorbs water and expands, shutting off the valve. It can be
verified that the valve has been activated if the pad has expanded and the arm of the valve is in its upper positon (Fig
35). If the valve has been activated, the pad must be replaced. A spare pad has been supplied with the product, please
follow the steps below to change the pad.
