06Frequently asked questions
How much space does it need?
A clear lane and a metre or so either side. We measure on the survey.
Can it go right at the door?
Not usually. Set it back so a line can form inside, not outside.
What happens in a power cut?
Many models have a built-in battery, and a small UPS covers the rest. We confirm backup on the survey.
