This article covers what your team should arrange in advance, so the trial produces a usable result rather than an impressive demo.
Define the trial area and the standard
Choose one grill line and the surfaces around it: the cooking deck, splash backs, the near section of the hood and the filter, and the adjacent wall. Limiting the scope keeps the comparison honest and makes repeat cleaning possible under the same conditions.
Then set the passing standard in plain words. Decide what counts as clean at the end of a shift and what counts as clean at the end of a deep cycle. Write both down before the trial starts. A standard set after the cleaning has already happened tends to follow the result.
Buyers comparing commercial steam cleaning equipment should request the same written standard from the supplier. If the supplier describes their process in vaguer terms than your own checklist, the trial will not tell you anything useful about day-to-day performance.
Prepare the grill itself before any steam is applied
Steam works on residue that has been partly loosened, not on a thick layer of baked carbon. Staff should scrape loose debris and remove accumulated grease from the deck, gutters and grease tray first, and bag that waste for normal disposal. This single step changes trial time more than any machine setting.
Next, confirm the equipment is cool, isolated from its power supply, and dry at electrical connection points before anything wet goes near it. Check which parts carry ratings that forbid immersion or jet washing, and separate those parts for hand cleaning with a cloth.
Finally, clear the floor around the line and protect anything nearby with a cover. Steam releases loosened grease in fine droplets that settle on adjacent surfaces; a prepared work area prevents the trial from simply moving the soil to the next station.
Prepare staff and safety arrangements
Run the trial with two people, not the whole team. One operator works the lance; the second handles wiping, drainage and the record sheet. Rotate the roles during the trial so both people learn the full process, and you learn whether the method holds when your usual operator is off.
High-temperature steam needs protective clothing that the kitchen does not normally use: heat-resistant gloves that reach past the wrist, a full apron, closed footwear with a grippy sole, and eye protection when working overhead at the hood and filter. Long hair tied back, sleeves down, and a posted rule that the lance is never pointed at a person are the minimum controls.
Tell the front-of-house team when the trial is running. Steam and hot water in a service area need a barrier, a sign, and a clear route for staff carrying hot plates.
Check the utilities the machine needs
Fixed units in the HW02 series run on a 220 V supply and use a tap-water inlet. Before the trial, have someone confirm that an outlet is reachable without an extension lead crossing a walkway, that the water supply connects to the fitting the machine requires, and that drainage is available at the work area rather than a bucket carried across the kitchen.
On the HW02, the published figures include 6 kW heating power, steam at 160°, vapor pressure at 0.8 MPa, and an 80 L tank in SUS304 stainless steel. Staff should walk through the dry-steam and wet-steam modes and the safety features listed for the machine — leakage, short-circuit, high-temperature and water-shortage protection — before starting the timed run, so that a mode change is not learned during a service.
Confirm those figures against the specification sheet for the exact unit you are trialling, and against your local supply conditions, since installation requirements and local rules differ by site.
Record what the trial produces
A trial without a record sheet becomes an opinion. Log the time from setup to handover, the water and power used if the machine displays it, and whether the written standard was met. Photograph the deck, splash back and filter before and after the same run. Note what the operator could not reach, because that is the list of accessories and techniques to address before you clean the second line.
If your team's current problem is heavy grease on cooking equipment rather than general surfaces, ask the supplier about heavy-duty steam cleaning machine configurations that match the surface area you are responsible for, and request a trial against your own standard.
Common preparation mistakes
Trials usually fail for three reasons. Staff put the machine straight onto a heavy carbon build-up without scraping, so the result looks poor and the equipment is dismissed. The trial is run during service, so interruptions inflate the time and the comparison means nothing. And only the most confident operator takes part, which hides the training time a real team will need.
The useful trial is prepared like an audit: a fixed scope, a written standard, prepared equipment, protected staff, working utilities, and a record sheet. Set those up and the same session tells you both the cleaning result and the process you would hand to your team.
