NOTE TO INSTALLER: Please leave this information with the Maintenance Department.
Haws electric water coolers are not designed or recommended for outdoor or corrosive
environments such as enclosed chlorinated pool areas. Consideration must be made at the time
of installation to adhere to state and/or local codes and environmental/atmospheric conditions
such as, but not limited to, dust, corrosion, freezing etc. These conditions will void the
warranty.
A ground-fault circuit breaker shall be installed
in the branch circuit supplying fountain
equipment. NEC680-51(a).
NOTICE: This water cooler must be connected to the water supply using a dielectric coupling.
The grounding of electrical equipment such as telephone, computers, etc., to water lines is a
common procedure. This grounding may be in the building, or may occur away from the
building. This grounding can cause electrical feedback into a water chiller, creating an
electrolysis which causes a metallic taste or an increase in the metal content of the water.
This condition is avoidable by using the proper materials indicated under Installation Section.
A. Water supply line pressure must be maintained between 20 psi and 105 psi. Bi-level water
fountain units require a minimum of 40 psi.
B. The ambient air temperature must be maintained between 60⁰F and 105⁰F during operation.
C. Do not allow water to come into contact with live electrical wires because short-circuiting and
shocks can occur.
D. WARNING: Beware of rotating fans when covers are removed.
E. Care should be taken not to puncture refrigeration system lines. Some lines contain gas
under high pressure.
F. Install cooler to conform to all applicable codes, including the National Electrical Code.
