9. Modular Installations

When used in modular installations, the LFTWHG2 hot valve 

assembly can be field configured to provide hydraulic isolation of 

units that need service or repair while other units remain operat-

ing. To provide hydraulic isolation from a pressurized hot water 

main, the pressure-activated seal must be rotated 180 degrees 

from the bottom port to the upper port as follows;

1.   With the valve in the closed position (handle facing forwards), 

remove handle plug, handle and stop plate;

2.   Place handle back on rotor hub and rotate 180 degrees so 

handle is facing rearward;

3.   Remove handle and re-install stop plate aligning the notch 

(marked with a X) with the nub on the body;

4.   Re-install handle (facing to the rear) and handle plug. The 

valve will now provide hydraulic isolation from a pressurized 

hot water main and be locked closed to prevent operation of 

water heater.

5.   To place heater back in commission, reverse the above pro-

cess.
