When a fixed machine arrives on site, the equipment is rarely what causes the delay. The delay comes from a gap between the paperwork in the quotation and what the installers were told on the morning of the visit. Before a service team mobilises to install a fixed steam cleaning machine, they should be able to answer the following questions in writing.
1. Which duty was this unit bought for?
Fixed units in the PowerDe cleaning range are sold for different jobs. The HW02 page describes vehicle exterior cleaning at fuelling stations and parking areas, interior vacuuming and disinfection, and engine-compartment cleaning. Other models in the same series are positioned for cleaning and disinfecting hospital beds and medical machinery. A crew briefed only on "a steam machine" cannot tell whether they are commissioning a vehicle bay or a disinfection routine in a clinical area, and those two duties carry different utilities, access rules and safety paperwork.
2. Which document is the machine's real identity?
Treat model labels as references, not as facts. On the fixed-unit listing, the model name in the product title and the wording used in the description of that same item do not match. Installers should work from the nameplate on the machine and from the confirmed order document, and should report the discrepancy to the supplier instead of settling it at the wall. The same discipline applies to numbers. The published datasheet for one fixed model covers heating power, steam temperature, vapour pressure, tank volume, overall dimensions including handles, water inlet type and working voltage. None of those values carry over to another model or to an accessory. Anything the crew needs that is not on the sheet they hold — hose length, noise, water consumption — has to be requested before the visit, not inferred on site.
3. Can the supply carry a heater that runs for hours?
A fixed machine is a heater first and a pump second. Before any cable is pulled, the electrician needs the nameplate current and the length of run from the distribution board, plus protection and cable sizing confirmed for a load that stays hot for long periods. Battery-powered mobile units in the same range are a different case and must not be assumed to need the same circuit. If the planned position has no spare capacity, the answer is a distribution change, and that belongs in the quotation rather than in an improvised extension lead.
4. Where does the water come from, and where does the run-off go?
The fixed units are listed with a tap-water inlet and a specific fitting, which has two consequences for the installer. First, confirm the inlet thread and size against the site tap before the fitting is ordered; a mismatch costs a day of commissioning. Second, water-shortage protection only means something if the crew knows how the machine signals a restricted or empty supply and does not run it against one.
Drainage is the other half of the decision. Steam cleaning uses far less water than a hose, but the run-off carries oil, grease and grit. In a vehicle bay that normally has to pass through the oil-water separation arrangement the site already operates. Confirm the local requirement with the site owner before the machine is positioned, because in practice the drain sets the position, not the socket.
5. What protections are fitted, and what do they forbid?
The literature for these machines names protection against leakage, short circuit, high temperature, high voltage, water shortage and high-voltage explosion. The count recorded for the same model differs between sources, so list the protections your unit actually declares and drop the tally. What matters on site is behaviour: these are shutdown and safety layers, not permission to work faster. A machine with high-temperature protection still delivers hot steam and hot surfaces, so the induction needs insulated gloves, closed footwear, and a hard rule that no lance is ever aimed at a person or at an energised panel.
6. Which mode belongs to which surface?
Dry steam and wet steam are not two names for one setting. Dry steam carries most of the heat with little free water, which suits degreasing and surfaces where run-off is unwelcome. Wet steam carries more water and suits loosening heavy soil. On a vehicle that usually means working top-down, keeping the lance moving, and keeping steam away from open electrical connectors, instrument openings and air intakes. Engine-compartment cleaning is a listed application, but it should follow a written procedure agreed with the site, not an operator's judgement on the day.
7. Measure the doorway, not the room
The fixed models are floor-standing cabinets whose overall footprint includes handles. Check the loading door, the internal door and the lift against those dimensions before delivery; a unit that fits the bay but not the entrance is an expensive problem. The chosen position then needs a level, non-slip floor, drainage within reach, and clearance on the operating side so the operator can move with a live lance. Keep the vehicle traffic lane clear of the hose route, so nobody has to step over a line while carrying steam.
8. Commissioning and handover
Do not sign off on "it makes steam". A usable handover covers a cold start with a full tank, a dry-steam run and a wet-steam run, verification of each protection the datasheet declares, and confirmation that the inlet fitting holds at working pressure without weeping. Then record three items in the site file: the machine identity exactly as printed on the nameplate, the confirmed order document, and the maintenance intervals and spares the supplier will actually keep in stock.
9. Consumables, water and the long tail
Heated cleaning machines fail on water rather than on luck, and scale risk depends on what the site supply contains. Agree the water treatment method and the descaling interval with the supplier at handover, and write both into the maintenance plan. Nozzles, hoses and seals are wear items; identify them from the nameplate of the machine you own and keep a working set on site, so the bay is not standing idle while a part is shipped.
10. Send this before the visit
A short, complete brief removes most on-site surprises: the order document and the declared machine identity; the intended duty, including whether disinfection or vehicle work is in scope; photographs of the planned position showing the drain and the distribution board; the inlet fitting size and the local drainage requirement; and the name of whoever signs the commissioning record. Shenzhen PowerDe Automation Precision Equipment works with integrators and end users on customized cleaning equipment and on hardware testing, so fit, utility and service questions are worth putting to the engineering team in writing while the quotation is still open, not during installation.
Where a site needs a fixed bay plus a separate machine for an area with no supply at the point of work, the PowerDe cleaning equipment series also covers mobile and hand-pushed units. The rule for the service team stays the same either way: install to the confirmed document, never to a summary.
