Start-Up Preparation
4. Set the primary thermostat to the highest
possible setting.
SECTION X - Start Up Preparation
Check System and Domestic Water
Chemistry
Do not use petroleum-base cleaning or
sealing compounds in the primary sys-
tem. Damage to seals and gaskets in the
system components could occur, result-
ing in substantial property damage.
System water including additives must be
practically 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 primary system water pH
between 6.0 and 8.0. Check using litmus
paper or contact a water treatment compa-
ny for a chemical analysis.
If the pH does not meet this requirement,
do not operate the ELITE or leave the unit
filled until the condition is corrected.
Water Hardness Less Than 7 Grains
For areas with unusually hard water (hard-
ness above 7 grains) consult a water treat-
ment company.
Chloride Concentration Less Than 80 mg/L
For those installations that use a water soft-
ener or conditioner, consult the water treat-
ment company.
Any water conditioning system must
be installed and maintained in accor-
dance with the water conditioner’s
manufacturer’s specifications and
within the operating guidelines of the
ELITE.
Chlorinated Water
Do not use the ELITE inner or outer tank to
heat a swimming pool or spa directly.
Maintain the chlorine level of the water in
the inner and outer tanks at levels consid-
ered safe for drinking.
Flush Primary and Domestic System to
Remove Sediment
The installer must flush both the primary
and domestic system to remove any sedi-
ment to allow proper operation of the
ELITE.
Flush the systems until the water runs clean
and is free of sediment.
For primary zoned systems, each zone
should be flushed through a purge valve.
Purge valves and isolation valves should be
installed on each zone to allow for proper
flushing of the system.
Check and Test Antifreeze
For primary systems containing antifreeze
solutions, follow the antifreeze manufac-
turer’s instructions in verifying the
inhibitor level and to ensure the fluid char-
acteristics are within specification require-
ments.
Due to the degradation of inhibitors over
time, antifreeze fluids must be periodically
replaced. Refer to the manufacturer of the
antifreeze for additional instructions.
