3. Installation Preparation - Read
Before Beginning Installation
For correct and safe installation, please read these
instructions completely.
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. Drain fittings which are provided by
the installer should be plastic to electrically isolate the
chiller from the building plumbing system.
NOTICE
Warranty is void if installation is
not made in accordance with
current instructions.
• Hose sets are not to be used for connecting to
water mains.
•
Always shut off the valve at the installation/ service
area to reduce risk of water damage.
•
Thoroughly flush all water lines and fittings of all
foreign matter before connecting to chiller.
•
If inlet pressure is above 100 psig (0.69 MPa),
a pressure regulator must be installed in water
supply line. Any damage caused by the water
pressure outside its rated pressure is not covered
by warranty.
