Price ambiguity: product page (and its own product name) shows a struck-through reference price of SGD 1,898 against a currently-charged price of SGD 1,098 (42% off, the steepest of the four novita models in this dataset), no visible end-date. Recorded the charged price (1,098) per SCHEMA.md's perpetual-sale rule (record what a buyer actually pays today); the 1,898 strikethrough is an anchor figure kept here for the record. Flagged for quarterly re-verification — a 42% swing on reversion would materially change this model's TCO ranking. This is a portable/countertop unit with a manually-filled 4.8 L source tank (not a direct-pipe model) — classified type: tank, water_source: manual_refill, distinguishing it from novita's pipe-in dispensers (e.g. novita-w1i) also in this dataset. It also has a 1.2 L cold-water tank and a 1.0 L ice reservoir. outputs recorded as [hot, cold] — the ice-making function is not one of the schema's output categories (hot/cold/ambient/sparkling) and is described only in notes. Warranty: "5 Years Warranty" appears directly in the product's own published name/title on novita's site, distinct from the general 1-year standard warranty applied to other novita models in this dataset (W1i, W62 Plus, W38) — recorded as published, but exact coverage scope (parts vs labour, exclusions) is not itemised on the product page. installation_fee_sgd recorded as 0: this is a plug-and-play countertop unit with a manual refill tank; no installation service is offered/required per the product listing (unlike novita's pipe-in models, which use the SGD 120 standard installation fee). Certifications: none formally scoped/published on novita's site; left empty per schema. An unrelated marketing blog post (novita.com.sg/blog) described this model's filters as "NSF-certified" and "tested to comply with Singapore Standards (SIS)," but no certificate, standard number, or tested-claim scope is published on the product page itself — per schema's rule that vague marketing claims go to notes, not certifications, this claim is recorded here only, unverified.
