PROCEDURE TO BALANCE
1. MAKE SURE NO WATER IS BEING DRAWN IN THE BUILDING. OPEN BALANCING VALVE #1
APPROXIMATELY HALF WAY AND START CIRCULATOR. KEEP BALANCE VALVE #2 CLOSED
AT THIS TIME.
2. OBSERVE TEMPERATURE UNTIL IT STABILIZES.
3. CLOSE BALANCING VALVE #1 SLIGHTLY IF TEMPERATURE IS TOO HOT, OR OPEN IT
SLIGHTLY IF TEMPERATURE IS TOO COLD. ALLOW TEMPERATURE TO STABILIZE, REPEAT
UNTIL DESIRED CIRCULATION TEMPERATURE IS SET.
4. IF UNABLE TO REACH DESIRED TEMPERATURE WITH VALVE #1 IN THE FULL OPEN
POSITION, OPEN BALANCE VALVE #2 IN SMALL INCREMENTS (i.e. 1/8, ¼, 3/8, ETC) UNTIL
DESIRED TEMPERATURE IS ACHIEVED.
NOTE:
FOR MULTIPLE TEMPERED LOOPS, A BALANCING VALVE AND CHECK
VALVE MUST BE INSTALLED ON EACH LOOP AFTER TEMPERED FIXTURES
