A crate marked PowerDe HW03 has just arrived at your loading bay, and the supplier wants a signature. Before you sign, run a structured acceptance check. A fixed steam cleaning machine such as the HW03 is usually installed in one place and used every day afterwards, so a missing adapter, a mismatched power supply, or a silent fault in the safety circuit is far cheaper to catch on day one than after commissioning. The steps below follow the machine's published specification, so you can verify each item against the nameplate and the manual rather than guessing.
1. Inspect and unpack before you sign
Check the packaging for punctures, crushed corners, or wet staining before the driver leaves. Photograph any damage on the spot, including the strapping and the pallet, because carriers usually allow only a short window for transit damage claims. Then unpack and lay everything out against the packing list. For the HW03 you should have the machine itself, the high-pressure water gun with nozzle, the water inlet hose and adapter, the power cable, and the user manual. If anything is missing, note it on the delivery note instead of discovering it later during installation.
2. Confirm the nameplate matches the order
Read the nameplate before powering up. The parameter table on the PowerDe product page lists this unit as PowerDe® HW03 (220V), made by Shenzhen PowerDe Automation Precision Equipment Co., Ltd. The descriptive text on the same page also refers to the machine as "PowerDeHMW3 (220V)", so the model marking on your crate or nameplate may not match the wording of your purchase order. That is not automatically a problem, but it should match what you ordered. If the marking differs from your contract, ask the supplier to confirm in writing which designation applies to your unit, and record the serial number for your asset register and future service requests.
3. Check the power supply and water connection
The HW03 runs on a 220 V supply with 4.5 kW of semiconductor heating power. Before the first start, confirm that the outlet or distribution circuit serving the cleaning area is correctly rated for that load, properly earthed, and protected by a residual-current device. Do not rely on an extension lead that was never intended for a continuous 4.5 kW heating load.
On the water side, the machine is fed from a tap through a 4-point internal thread joint. Have the matching hose and adapter on hand during acceptance, because a wrong fitting is the most common reason a new machine sits unused while a part is posted. Fill the 50 L clean water tank and check that the tank shell, lid seal, and inlet connections are intact and leak-free.
4. Run the functional tests
With water in the tank and the gun connected, start the machine cold and watch the heater indication respond. Steam should reach the lance within a few minutes of a cold start; note the actual time in your acceptance record so you have a baseline to compare against later. Then work through the modes:
- Dry steam. The output should come out nearly dry, with little visible water flow. This is the mode used for medical equipment steam cleaning, such as hospital beds and medical machinery, where high-temperature steam disinfects without soaking the surface.
- Wet steam. Switch to wet steam and confirm the output carries more moisture, which is what you want for loosening dried residue on trays, trolleys, and hard surfaces.
- Mode switching. Change between the two modes several times. The selector should respond every time, with no loss of steam and no error behaviour between settings.
- Water gun and nozzle. The HW03 cleans through a high-pressure water gun with a nozzle. Check the trigger action, the spray pattern, and every coupling for leaks while the system is under pressure.
5. Test the safety protections
PowerDe lists leakage protection, short-circuit protection, high-temperature protection, high-voltage protection, water-shortage protection, and high-voltage explosion protection on this machine. You cannot bench-test every circuit on the loading dock, but two of them are easy to confirm:
- Water-shortage protection. Run the tank low and confirm the machine cuts the heater instead of continuing to heat an empty tank.
- Leakage protection. Press the test button on the inline protection device; it should trip cleanly and reset without tools.
For the high-temperature and high-voltage protections, confirm the corresponding fuses, cut-outs, and warning labels are present and undamaged, and that the manual describes how each protection behaves. If a protection trips during your tests and will not reset, stop and contact the supplier before use.
6. Check steam output and physical condition
Hold your hand at a safe distance from the lance. The steam should arrive consistently hot, with no cold sputtering and no pulsing that suggests a blocked line or an air leak. The gun should hold pressure without a steady drip from the nozzle. Then inspect the machine itself: the HW03 is a hand-push unit measuring 1,150 mm × 520 mm × 1030 mm, so check that the handle frame is square, the casters roll freely, panels are fastened, and no hose is kinked or pinched against the frame. A frame that was dropped in transit rarely shows it in a single obvious dent — it shows later as a wobble or a leaking joint.
7. Collect the paperwork
Acceptance is not finished until the documents are in the file: the user manual, the warranty terms, the invoice, and your own signed record of the tests above, including the cold-start time and the serial number. Hospitals and clinics often need this record for procurement or biomedical equipment files, so ask the supplier which certificates apply to your unit and request copies with the machine rather than after installation.
Acceptance checklist at a glance
| Check | What to verify |
|---|---|
| Packaging | No punctures, crushes, or wet staining; damage photographed before signing |
| Packing list | Machine, water gun with nozzle, inlet hose and 4-point internal thread adapter, power cable, manual |
| Nameplate | Model marked PowerDe® HW03 (220V), 220 V, 4.5 kW; serial number recorded |
| Power supply | Earthed 220 V circuit rated for the 4.5 kW load, protected by an RCD |
| Water system | 50 L tank fills without leaks; tap joint connects without adapters missing |
| Steam modes | Dry and wet steam both respond; mode switching repeats reliably |
| Protections | Water-shortage cut-out acts; leakage protector trips and resets |
| Mechanical | Frame square, casters free, no kinked hoses, no leaks under pressure |
| Documents | Manual, warranty, invoice, and your signed test record filed together |
Common acceptance failures — and how to avoid them
- Missing inlet adapter. The 4-point internal thread connection is not a fitting most facilities keep in stock. Order the matching hose with the machine.
- Wrong supply circuit. A 220 V outlet on a shared lighting circuit will trip under a 4.5 kW heater. Check the circuit before the first start, not after.
- Model-name confusion on paper. HW03 and HMW3 wording both appear in PowerDe's listing for this class of machine. Get the correct designation confirmed in writing so your warranty claim is not disputed later.
- Signing without a test run. A machine that has never produced steam is the hardest fault to attribute to transit after the crate is gone. Run the steam test on delivery day.
After acceptance
Once the machine passes, file the checklist with the serial number and store the manual where the cleaning team can reach it. If you are comparing configurations — a different tank size, voltage, or mode set — the PowerDe cleaning equipment range covers fixed, hand-pushed, and driving-style steam machines, and the manufacturer offers customised configurations. For the full specification of the fixed series, see the fixed steam cleaning machine page, or contact PowerDe directly at sales@powerde.net or +86 13023198376 to confirm what should be in the crate before it ships.
