BathSelect® Heritage Series — Technical Specifications & Advanced FAQ
Detailed, spec‑grade information for Bauhaus™, Deco™, Modernist™, Renaissance™, Neoclassic™, Brutalist™. Figures below are typical design targets. Always verify the latest cut sheets, BIM families, and wiring diagrams for the exact SKU.
How do I size a shared transformer for a faucet + dispenser set?
Add the worst‑case VA of each device. Example (Modernist set): faucet 12 VA peak + dispenser 10 VA peak → choose ≥25 VA SELV driver. If powering multiple sets, include diversity but keep 20–30% headroom. Keep homeruns short and use 18 AWG to minimize voltage drop.
What’s the expected battery life and how do policy settings affect it?
Battery life depends on cycles/day, water temp, and policies (dwell, lockout, hygiene flush). Latching valves draw only during the open/close pulse. As a rule of thumb: medium traffic (400–600 cycles/day) with hygiene flush off yields 12–18 months; add hygiene flush every 24 h and expect ~10–15% reduction. For 24/7 venues, AC is recommended.
How do I mitigate sensor false triggers near mirrors or glossy stone?
Use models with ToF assist (Bauhaus, Neoclassic) and enable reflective‑surface compensation. Maintain the sensor‑to‑basin offset shown in the cut sheet and keep faucet–dispenser spacing at 150–250 mm (6–10 in) center‑to‑center to avoid cross‑triggering.
What are the recommended hygiene flush and thermal purge practices?
Hygiene flush: 3–8 s after 12–72 h idle to refresh lines. Thermal purge: planned maintenance at 60–70 °C for 2–5 min with area control and signage. Pair with ASSE 1070 mixing valves; auto‑revert to tempered after purge. Log the event in O&M records (BLE snapshot on Modernist).
Which mixing strategy should I use for campuses?
At each lavatory, use ASSE 1070 point‑of‑use mixing to cap outlet temperature. For building‑level control, use ASSE 1017 thermostatic master mixing plus recirculation and commissioning flushes. Keep pressure balance between hot/cold for the Modernist mixer to maintain stable flows.
Any guidance on hydraulic noise and water hammer?
Maintain straight‑run lengths upstream of regulators, keep strainers clean, and use hammer arrestors per code on aggressive mains. Valve timing ramps reduce spikes; if noise persists, add PRVs and verify 20–80 psi operation band.
What soap chemistries are compatible? How do I change products?
Liquid 1–3000 cP across all liquid dispensers; foam models use foam‑specific pumps. Avoid particulates. For alcohol‑based products, verify seal compatibility in the SDS. When switching chemistries, rinse the tank and run the purge/prime routine to clear the lines.
What are the environmental and EMC considerations?
Electronics are IP65 and designed for commercial restroom EM environments. Use dedicated low‑voltage runs, avoid sharing conduits with mains, and keep cable lengths within the wiring diagram limits. In high‑EMI areas (elevators/VFDs), use shielded low‑voltage cable and bond shielding per diagram.
How do I plan for vandal resistance and uptime in public spaces?
Use Brutalist or Deco models with vandal bezels, lockouts, and anti‑rotation gaskets. Specify tamper‑resistant fasteners, add anti‑tamper conduits for exposed low‑voltage runs, and stock spare regulators, seals, and pump modules for rapid swaps.
What finish care is recommended for PVD and Chrome?
Use non‑abrasive cleaners and microfiber. Avoid chlorine bleach and scouring pads. PVD stacks provide high surface hardness and chemical resistance; still, test new housekeeping chemicals on a small area first.
What deck thickness and basin pairing rules should I follow?
Standard deck 12–45 mm depending on model; see spec table above. Pair laminar outlets with shallow basins to reduce splash; align spout projection to fall ~30–50 mm inside the bowl’s deepest zone.
Can I centralize soap with remote tanks?
Yes. Use optional 5 L remote tanks on a per‑bank basis. Follow max lift/line length in the dispenser guide; prime after refill. Label lines for product type to avoid cross‑mixing.
Do these devices store user data?
No personal data is stored. BLE (Modernist) is local‑first and used only for commissioning snapshots (settings and usage counters). No cloud connectivity is required by default.
