What should be included in an acceptance check for PowerDe HMW3 without battery?

Start with the paperwork, before touching the crate

The model marking on the nameplate should read PowerDe HMW3 (Battery not included), matching the order line. That line matters more than the carton label, because the supplier also sells a version of the same cart that ships with a battery. Cross-check three things on the packing list and the nameplate: the model string, the quantity of cartons, and whether a battery carton is listed at all. If the packing list shows a battery carton and the crate does not contain one, stop and photograph the seal before opening. That is a shipping discrepancy, not a defect, and the claim handling is different.

Ask your supplier to state the intended battery specification in writing before purchase, then verify against what arrives. The published specification for this machine lists a 48 V battery as the working power supply. Whether the battery is supplied by the manufacturer or sourced locally, the receiving record should show which option you bought and what actually came in the box.

Physical and mechanical checks

Walk around the cart with the paperwork in hand. The published dimensions are L1150 mm x W520 mm x H1030 mm, so measure the floor space and the doorway where the machine will actually be used. A cart that fits the loading bay but not the hospital bed bay doorway or the lift gate is a layout problem you want to find on delivery day, not on day one of use.

Check the items below and record each result as pass, fail, or missing:

• Frame and panels: no dents, cracked welds, or displaced bumpers from transit.
• Wheels and castors: turn freely, no flat spots, brakes hold on a slope.
• Push handle: fixed securely, no play in the joints.
• Water tank: 50 L clean water tank, empty and clean inside, cap seals intact, no cracks at the moulding.
• Water inlet: tap water inlet with the 4-point internal-tooth fitting. Confirm your hose end actually mates with it, and note the fitting size in the receiving record.
• High pressure water gun, lance and nozzle: present, undamaged, seals present.
• Hose and cable routing: no kinks, no chafed insulation, connectors not crushed.
• Nameplate and serial number legible, and matching the packing list.

The accessory set is not published in the online specification, so do not accept "it should be included" as an answer. Hold the supplier's packing list and invoice, and tick every accessory line against them. Anything missing gets written on the delivery note before you sign.

Electrical checks on a machine that has no battery

This is the step most receiving teams skip, and it is the whole point of the battery-free variant. The machine itself carries a 4.5 kW heating load with a PTC semiconductor heater, and it runs on a 48 V battery supply, so the battery, its connector and its cable are the interface you are inspecting, not a battery you are charging.

• Confirm the battery compartment is empty as ordered, and that the compartment, mounting points and straps are undamaged.
• Inspect the battery connector and cable: pins straight and clean, no burnt marks, no crushed sheath, connector guard present.
• Measure the open-circuit voltage at the machine-side connector with a meter, and record the value against the battery specification you agreed. If your battery is supplied separately, measure the battery before first connection and record it.
• Verify the protection functions listed for this machine (leakage protection, short circuit protection, high temperature protection, high voltage protection, water shortage protection, and high voltage explosion protection) are documented in the manual, and that each one can be observed or tested during commissioning.
• Charge the battery on the charger matched to it. Charger output is not published for this machine, so confirm the charger specification with the supplier before the first charge, and never charge a lithium battery unattended in a storage area.

Record the polarity and connector type before any battery swap. Mixing connector types between a battery-free and a battery-included cart is a reliable way to destroy a controller, and it is invisible in a photograph.

Water and steam function test

Fill the tank with tap water, as the specification states, and run the machine through both modes in the order your manual describes. Keep a log with time, mode and observation.

• Water fills without leaking at the inlet fitting or the tank cap.
• The machine heats: the 4.5 kW PTC heater should bring the unit up per the manual, with the heating indicator behaving as described.
• Dry steam mode delivers steam at the nozzle, with an even pattern and no water hammer in the hose.
• Wet steam mode delivers steam with water carry, and the switch between the two modes is clean and repeatable.
• The high pressure water gun triggers, holds and releases correctly, and the nozzle seats properly.
• Water shortage protection triggers when the tank runs low. Test it deliberately once, on a safe surface.
• No abnormal noise, no steam leak at joints, no water pooling under the cart.

Steam temperature and steam pressure are not published for this machine. Commission it against the manual and record what you observe. That record becomes your baseline for future comparison, and your evidence if performance drifts later.

Application check against your actual job

Function tests prove the machine works; application tests prove it works for you. This model is positioned for cleaning and disinfecting hospital beds and medical machinery, so run the test on a real asset, not on a mock wall.

If your receiving site is a hospital, clinic or central sterile services department, run the cart through the doorway of the bed bay, down the corridor and into the lift. Test on a bed frame and on one item of equipment that is normally cleaned there. Check the noise against what the area allows, the hose reach against the working height, and the run time against a full cleaning round on a single charge of the battery you fitted. If the cart cannot finish one round, you have discovered a fleet-sizing problem while the supplier's warranty clock has barely started, and the remedy is a battery specification or a different cleaning machine from the cleaning equipment series rather than a service call.

Documentation and sign-off

Accept the shipment only when the following are in the file:

• Packing list and nameplate cross-checked, including the "battery not included" wording.
• Photographs of the crate on arrival, the nameplate, and any damage or discrepancy.
• Measured battery voltage, connector type, and the agreed battery and charger specification.
• Completed function test log with dry steam and wet steam observations.
• The protection functions listed above confirmed by observation or test.
• User manual, warranty terms, and the supplier contact for the site. For this equipment, PowerDe lists its contact as sales@powerde.net, +86 13023198376.
• Signed delivery note with every exception written on it before signature.

Then schedule the next check. Steam equipment fails predictably: seals, hoses, nozzle wear and inlet fittings. Write the intervals into your maintenance plan on the day the machine arrives, and keep the receiving log as the reference point every later reading is compared against.

The short version

Model marking matches the packing list and no battery was expected; frame, wheels, tank and gun undamaged; battery connector and cable clean and undamaged, with voltage measured against the agreed specification; both dry steam and wet steam modes working; water shortage protection proven; application walk-through completed in the real doorway on the real asset; everything recorded and signed. That list takes a receiving team about an hour, and it turns the first week with the machine from an argument into an inspection.
