Space, power and access: what a food vending machine needs from a building

A food machine that looks neat in a lobby photo can still end up on an extension cord, in the afternoon sun or across the trolley route to the service lift. One site walk with a tape measure and the operator's machine specification catches most of it.

Get that specification in writing before you agree a spot: size, weight, clearance and power all come from it. This is general guidance, not a building code; your building's rules, fire safety plan and electrician come first. Broader questions for an operator are in the checklist for evaluating an operator.

The spot: level floor, open door, clear exits

The machine needs a level, solid floor that holds its weight without wedges, room to open its door fully for restocking and cleaning, and space for a buyer to stand without blocking anyone. Keep it clear of fire exits, escape routes, fire equipment, lift doors and the main walking line through the lobby. It also releases heat, so leave the gap to the walls behind and beside it that the manufacturer specifies.

Power: a wall outlet, never an extension cord

The fridge inside runs day and night. The U.S. Fire Administration advises plugging major appliances directly into a wall outlet and warns that an extension cord used with one can easily overheat and start a fire (USFA). Before you sign:

• find a wall outlet close to the spot, ideally not shared with other heavy loads;
• get the outlet type and rating from the operator and check them against your building's supply;
• have any new outlet installed by a qualified electrician under your building's rules;
• agree who pays for electricity and how it is counted;
• ask what happens to the food and the machine after a power cut.

Heat: sun and dead air cost power

A fridge pushes heat from the cabinet into the room. Hong Kong's energy agency advises keeping one away from heat sources and direct sunlight, with space around it for air to reach the condensing coils, because trapped heat increases energy consumption (EMSD).

In a Thai building that rules out glass walls facing the afternoon sun, hot and humid semi-open areas, tight niches without airflow, and spots near a kitchen exhaust or a server cabinet. A machine fighting heat uses more power and works harder to keep food cold, which is the whole point with chilled food (the cold chain in a hot climate).

The delivery route, walked once

Restocking means wheeling food from a vehicle to the machine. Walk that route with the operator: where the vehicle stops, which door it uses (steps, thresholds and narrow doorways slow every delivery; a ramp or side entrance often helps), whether the service lift is needed, how far the chilled food travels, and how trolleys cross polished floors. The machine arrives and one day leaves the same way, so check that it fits through the doors and the lift.

Service hours belong in the agreement

Set restocking and cleaning hours outside the morning and evening rush, quiet hours with no visits, a sign-in routine with security or the front desk, and a contact for urgent service. Written into the agreement, these protect residents' peace and keep the machine stocked. The rest of the split is in operator and building responsibilities.

A spot residents will actually use

A machine earns its place only if residents pass it every day and can use it easily: a step-free approach near the lifts or the main entrance, room in front for a wheelchair, a pram or a shopping trolley, and a screen and pick-up door that people of different heights can reach. Good light for all the hours it is reachable and a view from the building's CCTV or front desk make it easier to use at night and less attractive for misuse. Keep it away from pool showers and corners that get wet in the rain.

Who can reach the machine, and when, depends on the building's rules for that area: decide it early and tell residents. The operator's contact details should be easy to find, so residents can report a problem quickly (SFA). If the operator fits its own camera, ask what it records and how recordings are used, and check that against your privacy rules. Some Plate Mate machines have a camera that helps us review disputed purchases and protect the machine.

The site check before installation

We assess the spot together with the building before installation: floor space, the power outlet, access for restocking, foot traffic, ventilation and direct sun, and your rules for access, working hours and appearance. Plate Mate supplies, installs, restocks and cleans the machine, handles technical service and supports buyers, within the agreed terms. Plate Mate pays the building rent for the spot; the amount and electricity are agreed individually.
