Hello - what is the height of the 18 bottle fridge (DH6) including the hinge at the top please?

DH6 - Dimensions (W x D x H): 345 x 450 x 770mm

Can I use this as a drinks fridge ? Do you have a couple flat shelves instead of wavy? I want to use it for cans as well as bottles

This model is supplied with wavy shelves only.

Can I put this model under a counter top, and does it also come in Stainless steel?q

This item can be placed under a counter top however we would advise a minimum space of 50mm for the rear of the fridge and 30mm for the top and both sides. 
We have a stainless steel version available.

what is the wattage of this chiller

The power rating for the DH6 is 85W.

Can I have this opening on the left

Good afternoon,

The door cannot be switched sides, it is only able to be fixed on the right.

Is there a setting for the light to remain on ?

Good afternoon,

There is a way to keep the light on for 10 minutes, but after this it will automatically switch off. Simply press the 'light' button and the internal light will come on.

My display is flashing LL, what doea that mean?

Good morning,

This error could mean a couple of things; the temperature is dropping below 0 degrees or there is an issue with the control panel.
We would suggest returning the unit for us to take a look at.
You can contact our support team at support@dellonda.co.uk and they will be able to assist you further.

how do i adjust the temperature it just sits st21/69, it is not chilling

To turn the unit on, press the settings symbol (the unit’s control panel will automatically lock out after 20 seconds of non-use).
To unlock the control panel, hold the settings symbol for approximately 2 seconds when an audible noise will be emitted to signify an active state. 
To change the temperature units displayed from Fahrenheit to Celsius, press and hold the light symbol for approximately 2 seconds. 
To set the required operating temperature use the up arrow symbol to increase it, and the down arrow symbol to decrease it. Each press will cause a 1 degree change in the set value.
