High Limit:
The high limit rapidly cuts off live line and zero line simultaneously to guarantee safety in case the
water heater happens to be faulty and water temperature exceeds the highest temperature pre-set in the
thermostat.
Safety Valve:
This appliance has a pressure relief valve (see Figure I). It must be installed in the inlet piping
(blue). It has been factory set at 0.8 MPa and is not adjustable. This valve relieves and discharges when
the actual pressure in the piping exceeds this set rate. The discharge outlet of this valve must face downward,
and the discharged water must be piped into or within 15cm above a suitable drain. Under any circumstances,
the drain line cannot be blocked, and must be open to atmosphere. Please refer to Figure VII for water
installation.
Safety Features
Enamel Coating Tank:
With the advanced anticorrosive technique, A. O. Smith Company evenly coats special silicon frit
onto the tank inner surface and fuse the frit coating to the steel at a high temperature of 870
°
C, forming a
durable enamel coated tank. It can endure huge impact without breaking off and completely isolate the
water inside the tank from the tank surface. It has passed the 100,000 times cycle test per UL (Underwriters'
Laboratories) standard and proved to be one of the most durable water heater tanks due to its antirust and
antiscale features.
