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.
