PROCEDURE TO BALANCE CIRCULATION SYSTEM
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.
REMEMBER! THIS IS A CONTROL DEVICE WHICH MUST BE CLEANED AND
MAINTAINED ON A REGULAR BASIS (SEE MAINTENANCE GUIDE AND
RECORD, MGR-1001).
