Installation Instructions; Before You Start - Dimplex OPTIMYST CAS250 Manual

The water tank, sump, sump lid, tank cap and air filters must be cleaned once every 2 weeks, particularly in hard
water areas.
Please note: Used in an environment where background noise is very low, it may be possible to hear a sound which is
related to the operation of the flame effect. This is normal and should not be a cause for concern.
The sump and the water tank in this product are treated with a biocidal product, Silver Biocide in order to control harmful
or unwanted organisms. This conforms with the latest relevant ISO standard
Do not drink the water from the sump or from the water tank(s).

Installation Instructions

This section describes how to set up your fire.

BEFORE YOU START

Ensure that all packing items are removed (read any warning labels carefully) and retain all packing for possible future
use e.g. in the event of moving house or returning the appliance to your supplier.
Before connecting to the mains supply, check that the supply voltage is the same as that stated on the appliance.
FURNITURE TYPE INSTALLATION
The CAS250 is intended to be used for furniture type installation - see Fig. 1 for product dimensions.
A minimum of 40cm clearance must be left between the metal bed and any shelf/enclosure above it, in order to
provide enough space for the flames/mist to form fully and not be obstructed.
There are slots at the base of the product that allows air to flow through, helping the mist evacuate effortlessly and
also to keep the electronic components cool.
The product needs ventilation from underneath or at the rear to operate effectively.
A minimum 200 is required, for examples - see Fig. 1A.

Where the product is left in the centre of a room/hall, drafts or pedestrian traffic passing by the appliance can have
an impact on the performance of the flame. For these installations, we would recommend putting a 4 sided glass
surround, that sits on top of the table/worktop/shelf, around the outlet (metabed) - minimum size 33x33x10cm high.
To assemble the appliance into a 'worktop' (or similar type shelf), a rectangular hole is required to allow the product to
be dropped into place. Adding a recess allows the product to be 'flush'/level with the worktop - see Fig. 2.
The metal bed is removable to allow access to controls and also to access the water tank, nozzle Lid, sump and
transducer - see Fig. 3. The 24V input connection is at the rear of the product - connect the jack from the power
supply unit to this input socket - see Fig. 4. A clearance hole (16-20mm) is required in furniture, to allow the lead
from the power supply unit to be fitted. Alternatively, the ventilation hole may be used. Insert the jack from the mains
cable to the power power supply unit (Do not Connect the Mains plug to a socket outlet until the appliance is ready
for operation). The product can be secured, by screw fixing through the base or at 2 sides - see Fig. 5 and 5a. (fixing
screws are not included).
Connecting the Transducer Unit :
1. Lift off the metal bed and place carefully on the table/worktop - see Fig 3.
3. Remove the water tank by lifting upwards and outwards - see Fig 6.
4. Remove the nozzle by unclipping (1) and lifting upwards and outwards (2) - see Fig 7.
5. The transducer will be inside the sump. Remove from its bag.
Locate the tab on the Transducer unit into the moulded recess in the base of the sump (1). Ensure that the cable does
not obstruct the Transducer disc. To prevent the cable becoming pinched between the nozzle and the sump, ensure
the cable exits through the slot at the corner of the sump (2). - see Fig 8.
Filling the Water Tank :
1. Lift out the metal bed and water tank, as desribed above.
2. Place the water tank in sink and remove cap, anti-clockwise to open - see Fig 9.
3. Fill the tank with decalcified/filtered tap water only. This is necessary to prolong the life of the flame and smoke
producing unit. The water should be filtered through a conventional domestic water filter unit and the filter should be
replaced regularly. Distilled water must NOT be used
4. Screw the cap back on (clockwise) - do not over tighten.
5. Place the Water Tank in the Sump, with the tank cap facing down and the flat side of the tank facing outward - see
Fig. 10.
