Coffee equipment technician - new-store equipment installation acceptance checklist - power, water, ventilation clearance, and level, four lines where one mistake costs years of repairs

You are the equipment technician for a coffee shop. The
buildout has reached equipment installation; turn this
acceptance checklist into a work-order version to walk
on installation day: keep the four-line structure, keep
every item as "how to verify / what goes wrong if
wrong," and leave numeric slots as [ ] for me to fill
from nameplates and manuals.

Put this background at the top of the checklist:
equipment acceptance happens at buildout tail-end,
before equipment is powered on - problems found now get
fixed by the contractor in a few labor hours; after
power-up, the cost is smashed walls and closed days.
The checklist's default stance: the contractor saying
"it's done" doesn't count; item-by-item verification
counts.

[Line 1: Power]
- Espresso machine: dedicated circuit (shared with no
  other high-draw equipment); wire gauge and breaker
  checked against the nameplate [ ]; voltage measured
  at [ ] V within nameplate tolerance - how to verify:
  multimeter reading, not the number written on the
  contractor's sheet
- Register every high-draw unit: grinder, ice machine,
  water heater, HVAC - each unit's wattage [ ] and
  circuit assignment; any two high-draw units sharing
  one circuit is an on-the-spot fail
- Grounding: measured on every unit - what goes wrong:
  a live chassis plus wet hands is an incident, not a
  repair
- Outlet positions vs. cord lengths: any unit that
  would run on an extension cord to reach must be
  fixed on installation day - it does not enter the
  "fine for now" list

[Line 2: Water and drainage]
- Espresso machine drain: the drain point's height
  relative to the machine's drain port per the manual
  [ ] - what goes wrong: poor drainage backflows into
  the machine and kills the water-path components
- Supply water: measured pressure [ ]; a pressure-
  reducing stage if outside the machine's operating
  band; water-treatment equipment (softener / filter)
  sits upstream of the machine, with working room left
  for cartridge changes
- Drain slope and floor drain: run a real test - how:
  pour a bucket of water and watch where it goes

[Line 3: Ventilation and clearance]
- Ice machine: back and side clearance per the manual
  [ ], nothing blocking the top exhaust - what goes
  wrong: condensing temperature runs over, ice
  production drops, high-pressure cutouts get frequent
- Refrigeration: distance from wall [ ]; heat-exchange
  faces not sealed behind counter panels
- Above the espresso machine: no combustible
  suspended items within [ ] of the heat exhaust

[Line 4: Level and mounting + test run]
- Grinder and espresso machine level: bubble level on
  the body in two directions - an unlevel grinder
  wears its burrs unevenly and the lifespan takes the
  haircut
- Three test runs: full pressure-up and one steam purge
  on the espresso machine; one test grind listening
  for abnormal noise; the ice machine's first batch
  with the cycle time [ ] logged as baseline
- Acceptance record: item-by-item signatures
  (contractor / equipment vendor / store), test-run
  readings photographed and filed - this record is the
  evidence in every future "it was off from day one"
  dispute

Formatting rules:
- Every item two beats: how to verify (with the tool) -
  what goes wrong if wrong
- Every [ ] annotated "check the equipment manual" -
  no "usually about this much" rules of thumb
- Verification ordered "before power - after water -
  powered test run"; no out-of-order execution

Why it is written this way

The checklist's timing matters more than its contents: the same inspection done on installation day is acceptance, done after opening is emergency repair - separated by a finished wall and a day of revenue. So the header locks in "before power-up" and the default stance "the contractor's word doesn't count": buildout communication is all verbal, and "the electrical side is done" carries exactly as much weight as whoever is listening. The checklist's job is to swap that sentence for a multimeter reading.

The four lines are ordered by accident cost, descending: power errors cost safety (grounding, dedicated circuits), water errors cost equipment (backflow killing water paths), clearance errors cost performance (the chronic "not broken but never right" of declining ice production), level errors cost lifespan (uneven burr wear). The three test runs each capture a baseline reading - especially the ice machine's first-batch time, the only future anchor for "ice has gotten slower"; skip logging it on day one and every later complaint floats without a reference.

Numbers stay as [ ] rather than "usually leave ten centimeters" because this is repair-trade hygiene: clearance specs on the same category of equipment differ by 2x across models, and a rule of thumb is simply wrong on some unit. Forcing the verifier to open the manual costs ten extra minutes and buys years of not guessing.
