CAUTIONS

Locate the dispenser at the proper counter
height, in an area that is convenient
for use. The location should be level
to prevent the unit or its contents from
accidentally falling, and strong enough
to support the weight of the unit
and water supplied.

Unit is not weatherproof. For safe and proper
operation locate the unit indoors where
the ambient air temperature is a minimum
of 70°F (21°C).

To assure proper operation and to avoid
damage to the unit, the incoming water
supply pressure must be at least 35 psi
(241 kPa) and not exceed 80 psi (552 kPa).

To assure proper operation and to avoid
damage to the unit, the incoming water
supply temperature must not exceed
140°F (60°C).

CAUTIONS

The unit must be transported in an upright
position. If laid on its side, the water must
be drained from the unit.

Do not use deionized water. Deionized water
will greatly shorten the life of the water
heating elements and plumbing components.

Water Quality Requirements – Incoming
water in excess of 3.0 grains of hardness
per gallon (GPG) (.75 grains of hardness
per liter) must be treated and softened before
being supplied to an Atmospheric Hot Water
Dispenser. Water containing over 3.0 GPG
(.75 GPL) will decrease the efficiency
and reduce the operating life of the unit.

Do not overtighten plumbing connections.
Overtightening may cause leaks.
