#1 Can the top be taken out so that it fits under the sink bench, we only have 830 available height?
Unfortunately the lid on the unit cannot be removed and the height is fixed to 850 mm.
#2 Will this model fit 820mm height space with the top off?
Euromaid do not recommend installing without the lid, and therefor do not supply detailed measurements with the lid removed. You will generally gain between 2cm-3cm.
#3 I note the question about taking the top off. Can the top be removed to enable the appliance to fit under a benchtop?
