1. Visually inspect THERM-X-TROL

 

for any damage. If damage 

exists return product for replacement.

2. Adjust pre-charge to equal incoming pressure.

 

If increasing the 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 psi or slightly 

higher than the pre-charge setting of the tank.

c. Isolation valve then needs to be closed.
d. The pre-charge pressure of the 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.

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 temperature 

and pressure increases caused by thermal expansion to a 

level well below the water heater relief valve setting.

1.  A professional plumber should check the complete heating 

system, including the THERM-X-TROL, yearly and more 

frequently as the system ages.

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.
