Start with what the inlet on the machine actually is
The first review item is the inlet itself, because it is the point where the building supply meets the machine. The datasheet for the fixed steam cleaning machine in the cleaning equipment series states a tap-water inlet with a 4-point internal tooth joint, 1/2 inch. That single line answers two practical questions: the machine is intended to be fed from a mains water connection rather than from a hand-carried container, and the fitting size tells the site plumber which adapter to prepare before installation day.
Write the inlet type and thread size into the enquiry you send to the supplier. If the site has a different fitting — a quick coupler, a garden-hose thread, a bulkhead fitting on a tank — ask for the matching adapter as part of the order. Adapters sourced locally on the day are the most common reason an installation is signed off but never used.
Match the tank arrangement to how long the machine must run
The same product record lists an 80 L tank in SUS304 for that fixed model. On site this matters in two ways. A tank of that size gives the machine a store of water to draw on, so a temporary drop in the incoming supply does not stop the shift immediately. And a stainless tank means the water sitting inside it between shifts is in contact with a material chosen for that duty, which is worth confirming when the supply is hard or the machine stands idle over a weekend.
Ask the supplier directly whether the tank is filled while the machine is running or only when it is stopped, and whether the machine stops on low water. Water-shortage protection is listed among the safety designs on that product page, but how it behaves — a warning, a pause, or a shutdown — is a control question rather than a spec-table question, and it changes the operator instruction.
Check the quality of the water you already have
"Tap water" on a specification line does not mean the supply at your site is the same as the supply at the factory. Before the machine is installed, take three readings from the point where it will actually be connected: hardness, whether the water carries sediment or rust from older pipework, and whether the line has been idle long enough to hold stagnant water.
- Hard supply: ask the supplier what they recommend for scale management and whether any part is specified as replaceable by the customer.
- Sediment or rust in the line: a filter or a flush point upstream of the machine is cheaper than a service call.
- Stagnant lines after a shutdown: flush the line before connecting, and record that step in the start-up instruction.
Do not accept a general statement that the machine tolerates any water. Ask which supply conditions the machine has been tested under and what the supplier's written maintenance advice is for the water quality at your site.
Confirm the electrical side that sits next to the water side
Water supply and power supply are planned together, because both terminate at the same point on the floor. The product record for the fixed model lists 220 V working voltage and 6 kW heating power, and it lists leakage, short-circuit, high-temperature, high-voltage, water-shortage and high-voltage-explosion protection among the safety designs. The electrical contractor needs the voltage and the heating power to size the circuit; the safety items are what you verify are present in the site installation as well, particularly where the machine will be used on a wet floor.
Check whether the mains supply at your facility matches the working voltage on the datasheet before the machine ships, and ask the supplier how the machine is to be earthed and protected at the installation point. On sites where a machine will be moved between bays, confirm the length and routing of the supply cable rather than assuming an extension lead is acceptable.
Review the site conditions that decide where the supply point goes
Machine dimensions are part of the water-supply question because they determine how close the unit can sit to the inlet and how the hoses run. The same specification gives L1200 mm × W800 mm × H1200 mm including handles, which is the footprint to measure against a wall, a drain, and a doorway. Fixed units sit where their supply sits; if the task moves around the yard, that is a different machine class.
The PowerDe cleaning equipment series also includes driving-style and hand-pushed machines with their own water and power arrangements, so the comparison is not "fixed versus none" but which supply arrangement matches the working pattern on site. Where a task falls outside the uses stated on a product page, ask the supplier to confirm it in writing against your actual conditions before it enters a procedure.
Put the answers into one installation checklist
A short checklist closes the review: inlet type and thread size, adapter supply, tank capacity and fill method, behaviour on low water, site water readings and the supplier's maintenance advice, working voltage and circuit sizing, earthing and leakage protection at the point of use, and the clearance the machine footprint needs around the supply point. Send that list with the enquiry, and keep the supplier's written answers with the machine file, so the same questions do not have to be asked again by whoever inherits the equipment.
If your site cannot offer a suitable fixed connection, or if the duty combines steam with water washing, foam, or dust collection on a moving platform, that is a configuration question for the engineering team rather than a choice between catalogue cards. PowerDe lists customized steam cleaning equipment, including module combinations and mobile platform structures, as a route for sites whose supply and layout do not fit a standard machine.
