THERM-X-TROL® STL (CL) SERIES THERMAL EXPANSION ABSORBERS INSTALLATION & OPERATION INSTRUCTIONS Models ST-35L(CL) through ST-600L(CL)Partial Aceptance Bladder Models FAILURE TO PROPERLY SEAL WILL RESULT IN LOSS OF PRECHARGE CAUSING PRODUCT TO FAIL. Installation THIS PRODUCT MUST BE INSTALLED BY A LICENSED PROFESSIONAL. 1. Visually inspect THERM-X-TROL for any damage. If damage exists return product for replacement. 2. Adjust pre-charge to equal incoming pressure. IMPORTANT: If increasing pre-charge pressure above 55 psig the following steps must be followed: a. Tank must be connected to the system with isolation valve open. b. System must be pressurized to 55-60 psig or slightly higher than the pre-charge setting of the tank. c. Isolation valve needs to be shut. d. Pre-charge pressure of tank can now be increased to the recommended high pressure setting. e. Bring system up to pressure, and then open the isolation valve to the tank. Failure to follow these steps could result in damage to the bladder and void all warranties. 3. Replace and tighten plastic cap on air fitting. 4. Install the THERM-X-TROL on the city supply line to the water heater at a point between the water heater and backflow preventer, check valve or pressure reducing valve (see Figure 1). 5. Once the THERM-X-TROL is installed, check the city supply line for any leakage. Make repairs if necessary. 6. Before the initial firing of the water heater, open any hot water fixture and draw water until all air is removed from the system. Turn the water heater temperature control to desired ending temperature level, (see water heater instructions). 7. To relieve initial thermal expansion, slightly open a hot water faucet. Continue until water heater aquastat temperature is satisfied. Once heater is at its operating range, no further bleeding of expanded water is required. 8. The system water heater and THERM-X-TROL will now be operational. The THERM-X-TROL will control pressure increases caused by thermal expansion to a level well below the water heater relief valve setting. Maintenance 1. A licensed professional should check the complete heating system, including the THERM-X-TROL, yearly and more frequently as the system ages. Operation 1. The THERM-X-TROL is installed in the supply line between the backflow preventer and the water heater. Its sealed-in air pre-charge prevents water from entering it until the system pressure exceeds the pre-charge pressure. 2. As the water temperature rises, expanded water enters the THERM-X-TROL’s non-corrosive water reservoir. The pre-charged air chamber absorbs the pressure increase, keeping system pressures below the relief valve setting. 3. As hot water is used, the pressure in the air chamber forces water back into the system until the THERM-X-TROL is empty. At this point, the pressure in the air chamber once again equals the supply pressure. 4. Water treatment is not to exceed 200° F or fall below 35° F.
