System Start-Up
SECTION IX - SYSTEM START-UP
Check System Water Chemistry
Do not use petroleum-base cleaning or sealing
compounds in the boiler system. Damage to seals
and gaskets in the system components could
occur, resulting in substantial property damage.
System water including additives must be practi-
cally non-toxic, having a toxicity rating or Class of
1, as listed in Clinical Toxicology of Commercial
Products.
Water pH Level 6.0 to 8.0
Maintain the water pH between 6.0 and 8.0. Check using
litmus paper or contact a water treatment company for a
chemical analysis.
If the pH does not meet this requirement, do not operate
the Cascade or leave the system filled until the condition
is corrected.
Water Hardness Less Than 7 Grains
For areas with unusually hard water (hardness above 7
grains) consult a water treatment company.
Chlorinated Water
Do not use the Cascade to heat a swimming pool or spa
directly.
Maintain the chlorine level of the water at levels consid-
ered safe for drinking.
WARNING
NOTICE
Flush System to Remove Sediment
The installer must flush the system to remove any sedi-
ment to allow proper operation.
Flush the systems until the water runs clean and is free
of sediment.
For zoned systems, each zone should be flushed through
a purge valve. Purge valves and isolation valves should
be installed on each zone to allow proper flushing of the
system.
Use of Antifreeze in the System
NEVER use automotive or ethylene glycol
antifreeze or undiluted antifreeze in the primary
system as freeze protection. This can cause
severe personal injury, death or substantial prop-
erty damage if ignored.
Determine the antifreeze fluid quantity using the system
water content volume and following the antifreeze man-
ufacturer instructions.
Consult product specifications page 56 for the Cascade
water volume.
Check with local codes requirements for the installation
of backflow preventers or actual disconnection from the
boiler’s cold water fill or make up water supply line.
Massachusetts Code requires the installation of a
backflow preventer if antifreeze is used.
Ensure the concentration of antifreeze to water does not
exceed a 50/50 ratio.
System water, including additives, must be practi-
cally non-toxic, having a toxicity rating or Class of
1, as listed in Clinical Toxicology of Commercial
Products.
