* According to the Water quality guideline for refrigeration air-conditioning equipment: JRA-GL-02-1994
Only designated circulating fluid is permitted to use for this system.
Potential system failure and fluid leak may occur if disregarded, which
results in electric shock, ground fault, and freeze.
Be sure to use fresh water (tap water) compliant with water quality
standards in the table below for ethylene glycol aqueous solution and
facility water.
If the periodic inspection finds a nonconforming substance in the
facility water, clean the facility water circuit and recheck the quality of
the facility water.
