Ferguson JWSH100150, JWSH100250 warranty Must be Identical Heaters

TWO TEMPERATURE - TWO HEATERS HIGH TEMPERATURE

WITH OR WITHOUT BUILDING RECIRCULATION

CAUTION: If the plumbing requires the use of pipes with dissimilar material (for example, steel and copper), use dielectric unions to preventan electro-galvanic action between the piping components with dissimilar materials.

TWO TEMPERATURE - THREE HEATERS (TWO PRE-HEATERS/ONE BOOSTER HEATER)

WITH OR WITHOUT BUILDING RECIRCULATION

MUST BE IDENTICAL HEATERS

FOR MULTIPLE HEATER INSTALLATION SEE MANIFOLD KIT SPECIFICATIONS, PAGE 33.

CAUTION: IF BUILDING COLD WATER SUPPLY HAS A BACK-FLOW PREVENTER, CHECK VALVE OR WATER METER WITH CHECK VALVE PROVISIONS FOR THERMAL EXPANSION OF WATER IN THE HOT WATER SYSTEM MUST BE PROVIDED.

CAUTION: If the plumbing requires the use of pipes with dissimilar material (for example, steel and copper), use dielectric unions to preventan electro-galvanic action between the piping components with dissimilar materials.

DANGER

TEMPERATURE SETTING SHOULD NOT EXCEED SAFE TEMPERATURE AT FIXTURES. SEE WATER TEMPERATURE CONTROL WARNING ON

PAGE 3. IF HIGHER PREHEAT TEMPERATURES ARE NECESSARY TO

OBTAIN ADEQUATE BOOSTER OUTPUT, ADD AN ANTI-SCALD VALVE FOR HOT WATER SUPPLIED TO FIXTURES.
