NOTE:
The
WL250
Water
Treatment
System
does
NOT
have
Sleep
or
Power
Saving
Mode
and
the
hot
water
should
be
a
minimum
of
185
°
F
under
normal
operating
conditions.
The
Hot
temperature
set
point
is
185
°
F
and
is
controlled
by
a
thermostat
on
the
side
of
the
tank.
There
is
a
resettable
overload
or
high
limit
safety
above
the
thermostat
on
the
side
of
the
tank
that
will
trip
to
prevent
damage
to
the
unit
if
the
tank
is
dry
heated
(turned
on
without
water
in
it).
The
WL250
does
NOT
have
Extra
Hot
capability
and
the
maximum
hot
temperature
is
189
°
F.
It
typically
takes
10
minutes
for
the
500W
to
heat
the
1.6
Liter
of
room
temperature
(ambient)
water
to
the
185
°
F
set
