Page 22: Section V - Primary Piping
Primary Piping SECTION V - Primary Piping General Piping Requirements Low Water Cutoff Device The ELITE is equipped with a factory installed pressure switch style Low Water Cut Off device. The minimum operating system pressure allowable with this device is 10 psig. Check local codes which require a low water cutoff device for compliance of this device.
Page 23: Circulator
Primary Piping CAUTION DO NOT install automatic air vents on a closed-type expansion tank system. Air must remain in the system and be returned to the expansion tank to pro- vide an air cushion. An automatic air vent would cause air to be vented from the system resulting in a water-logged expansion tank.
Page 24: System Piping - Multiple Units Installation
Primary Piping NOTICE If the radiant system tubing contains no oxygen barrier, a stainless steel heat exchanger must be used. Failure to install a heat exchanger could lead to premature failure of the outer tank and void any warranty claim.

Start-Up Preparation 4. Set the primary thermostat to the highest possible setting. SECTION X - Start Up Preparation Check System Domestic Chemistry WARNING 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.
Page 43: Use Of Antifreeze In The Primary System
Start-Up Preparation NOTICE 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. Use of Antifreeze in the Primary System WARNING NEVER use automotive or ethylene gly- col antifreeze or undiluted antifreeze in the primary system as freeze protection.
Page 44: Check Low Water Cut-Off Device
Start-Up Preparation 3. Fill the outer tank to correct system pressure. Correct pressure will vary with each application. NOTICE Typical residential system fill pressure is 12 psi. System pressure will increase when system temperature increases. Operating pressure of the system should never exceed 25 psi.
