Concept image only: not the worked D1 machine, a completed route survey or an approved pallet, ramp or handling arrangement.
The dishwasher is 680 mm wide. The kitchen door is 720 mm clear. Someone writes “fits” on the order—but the crated unit is 760 mm wide, and the delivery provider has not agreed to unpack it outside.
Check the equipment in the condition in which it will actually move, through the whole route. Appliance dimensions, packed dimensions and the provider's moving envelope are different records. Passing one doorway on paper does not establish a turn, lift journey or final placement.
This guide follows a fictional delivery from unloading point to kitchen. Its arithmetic finds questions to resolve before dispatch; it does not approve a handling method. For machine format and workload selection, start with the commercial dishwasher buying guide.
Ask which envelope the delivery provider will move
Obtain the exact offered model's current dimensional drawing, packed dimensions and shipping mass. Include accessories, pallet, protective framing and any projections relevant to the shipment. Ask the supplier to identify which document and revision apply to the actual order.
Then ask the delivery provider to describe its proposed moving arrangement. A trolley, protective material, securing equipment or other handling provision can change the space needed. Its people also need a workable route. Do not add an arbitrary allowance and call the result approved.
A real manufacturer example shows why the fields must stay separate. Moffat's linked Washtech UL specification sheet, June 2025, lists machine and packed dimensions separately. Its mass entries also differ from the packed weight shown on the UL product page when checked for this guide. That is a reason to resolve the applicable shipment information with the supplier, not choose the more convenient figure. Neither source describes our fictional machine below.
Keep unpacking and any proposed component removal as explicit questions. The manufacturer and responsible delivery/installation providers must establish what is permitted, where it happens and who performs it. This article supplies no instruction to tilt equipment, remove panels, alter a door or separate a machine from its pallet.
Worked route: the bare machine fits a door the package does not
All dimensions below are fictional, in millimetres. D1 has an unpacked outer envelope of 680 wide × 740 deep × 1,500 high. Its assumed packed envelope is 760 × 820 × 1,670. These are example values, not a listed dishwasher or a complete moving arrangement.
The proposed plan puts the packed 760 mm dimension across the route. The provider has not yet confirmed the handling equipment, total moving height, mass or permitted orientation. The following subtraction is therefore a dimensional screen only.
| Route point | Measured clear opening | Packed-envelope comparison | Decision still needed |
|---|---|---|---|
| R1: loading doorway | 900 wide × 2,050 high | 900 − 760 = 140 wide; 2,050 − 1,670 = 380 high | Confirm unloading and complete moving arrangement |
| R2: corridor | 850 clear width along measured straight section | 850 − 760 = 90 total width remainder | Survey projections, surface and approach; not a turn assessment |
| R3: lift doorway | 800 wide × 1,900 high | 800 − 760 = 40 wide; 1,900 − 1,670 = 230 high | Lift car, opening geometry, rating and provider method unresolved |
| R4: kitchen door | 720 wide × 2,000 high | 720 − 760 = −40 wide | Packed envelope exceeds this width; proposed route unresolved |
| R5: final approach | Right-angle turn beside fixed bench; geometry not surveyed | No valid numeric comparison yet | Provider needs full turn and positioning assessment |
Scroll the table sideways to see every column.
The 140, 90 and 40 mm width remainders are total differences, not that much space on each side. They do not include an unrecorded trolley, hands, protection or manoeuvring requirements. Height differences likewise exclude any unrecorded change caused by the moving arrangement.
At R4, subtracting the bare width instead gives 720 − 680 = 40 mm. That changes the arithmetic, not the delivery plan. An unpacked movement has not been authorised or assessed. The useful outcome is an open request: can the responsible providers establish an acceptable route and method, or is another route or equipment proposal required?
A doorway width cannot settle the corner or lift
Draw the route as connected spaces. Show the approach to each opening, door swing and usable open position, fixed handles, closers, counters, thresholds, overhead restrictions and changes of level. Record where and how the clear measurements were taken; a nominal door size on an old plan is not the opening available on delivery day.
For R5, measure both corridor legs and the space around the corner. Include the fixed bench and any doorway close to the turn. Give the provider a marked plan and photographs from both directions. A machine fitting a straight section does not establish that its rectangular moving envelope can rotate through the adjoining spaces.
Do not use the diagonal of the appliance as a universal turning test. The allowable orientations, approach, surrounding obstacles, handling equipment and people all affect the move. Leave the corner unresolved until the provider assesses the actual geometry.
For R3, request the lift opening and internal car dimensions, permitted use, booking conditions and relevant load information from building management. The provider needs the complete load, including its handling arrangement, to assess suitability with the responsible parties. A wide enough lift doorway is only one part of that assessment. This example specifies no lift rating or acceptable load.
Write where delivery ends and installation starts
Ask for named responsibility for unloading, movement through the building, unpacking, final positioning, connecting services, commissioning, packaging removal and removal of the old dishwasher. A price labelled “delivery” does not explain which of these tasks is included.
For a replacement, establish who disconnects and removes the existing machine and when the route becomes available. Photograph the current arrangement without dismantling it. Keep any services changes with the fitout services change register; a delivered machine is not a commissioned installation.
At the destination, distinguish the appliance footprint from the space needed to position, connect, inspect and later service it. Show the proposed final arrangement and the manufacturer's instructed access requirements. Door and hood movement, adjoining benches and accessory packages can make the last metre different from the rest of the route.
Ask the provider what happens if an agreed route is unavailable or the shipment differs from the reviewed information. Identify the contact who can stop and resolve the discrepancy. Do not let a booked vehicle turn an unresolved route into an improvised removal, lifting or tilting job.
Close the route questions before the truck is booked
Bundle the exact shipment reference, route revision, dated measurements, photographs and the provider's written assessment. Confirm access times, unloading location, building/lift bookings and any agreed site preparation. Have the venue and provider check that the same revision is being used.
In D1, the present record cannot be marked ready: R4 fails the assumed packed-width screen, and the complete moving arrangement, lift and turn remain open. Even R1 and R2 are not approved moves merely because subtraction gives positive numbers. Each row needs the relevant evidence and decision owner.
If a provider proposes a different route or permitted configuration, revise the affected measurements and decisions together. Retain the earlier version so the change is visible. Reconfirm the actual route before dispatch if doors, benches, floor surfaces or building access have changed.
Prepare a route brief that keeps the pinch points visible
For your own supplier brief, record equipment and moving envelopes, each route restriction, unresolved turns and responsible delivery decisions. Replace the fictional inputs with actual evidence and leave unresolved decisions visible.
Please assess this exact shipment through the attached route revision, including the unloading point, moving arrangement, lift, turn and final positioning. Confirm any permitted configuration changes and responsibilities in writing. Identify the evidence still required before dispatch.
Send that brief with your Atlantic Equipment enquiry. Compare commercial dishwashers with their full access and installation scope, rather than choosing a cabinet that fits only its final footprint.
Sources and example limits
Manufacturer documents checked 18 October 2026: Moffat's Washtech UL product page and its linked UL Series-3 WUL0040 specification sheet dated June 2025. These illustrate separate equipment/packing records and a mass discrepancy requiring clarification. No current shipping mass, handling method, lift permission or installation instruction is transferred to D1.
D1, every route dimension and all remainders are fictional. No site survey, delivery approval, minimum handling clearance, safe lifting capacity, tilt angle or authorised unpacking procedure is asserted. The actual supplier, delivery provider, building parties and installer must resolve their respective scope.
About this guide
Prepared by Atlantic Equipment. This guide follows a dishwasher from shipment information to final position. Its worked route shows why a bare-machine doorway calculation can conceal a packed-width restriction, an unassessed lift and a missing turn survey. Use the editable brief to give the responsible providers the same measurements and open questions before dispatch.
