Išorinis blokas statomas ant 400 mm rėmo su kondensato nuvedimu žemiau įšalo ribos.
Monobloko apsauga: privalomas magnetinis purvo ir oro separatorius (Zeparo), neužšąlanti išleidimo sklendė bei ≥ 50–100 L akumuliacinė talpa (ZV) atitirpinimo (Defrost) ciklui.
All [01–06] sub-assemblies, adapters, and gaskets stocked at Eigulių St. 21, Kaunas warehouse (10+ yr service support).
Confirm that AB122MNERAB connection matches the supply/return pipework and flow direction arrow.
Depressurise the heating circuit, fit the union tailpiece and tighten to factory torque.
Adjust the flow scale (Kvs / l/h) or controller setting according to room or boiler loop load.
Refill the loop, vent trapped air and verify leak-free operation under operating temperature.
Engineer pro tip: When installing Haier (AB122MNERAB), never wind hemp onto flat gasket seats or Eurocone O-ring cones – seal only tapered pipe threads.
Vytautas engineering compatibility note (AB122MNERAB)
Verified mating components for Haier (AB122MNERAB) matched by connection standard (DN / thread / M30×1.5 / RA Click) and hydraulic compatibility.
Yes, this Haier unit (SKU AB122MNERAB, category: Boilers & boiler room equipment) is manufactured to European EN 12828 hydronic standards. Verify the connection thread or nominal size (e.g. DN15 1/2", DN20 3/4", M30×1.5 or Danfoss RA Click) – our engineering advisor Vytautas lists directly compatible mating components on this page.
Genuine Haier components use corrosion-resistant alloys (DZR brass, bronze or stainless steel) and calibrated flow paths, preventing valve sticking, water-hammer noise and premature seal leaks over 10+ heating seasons.
When installing Haier MRV VRF system indoor unit AB122MNERAB, 3.6 kW (R32) (AB122MNERAB, retail price 538,00 €), check whether you need matching union tailpieces, Eurocone adapters, a mating thermostatic head or actuator. See the compatible parts section above.
Always observe the flow-direction arrow on the housing, depressurise the loop before fitting, and never apply hemp or tape onto flat union gaskets or O-ring cones.
