2. FOR HOT WATER SYSTEMS 50mm [2"] AND SMALLER

AND CHILLED WATER SYSTEMS USE IN-LINE AIR

PURGER IN LIEU OF AIR SEPARATOR.

3. SET PRESSURE REDUCING VALVE SO PRESSURE AT

HIGHEST POINT IN SYSTEM HAS A MINIMUM OF 28kPa

[4 PSIG].

4. PROVIDE STRAINER IN AIR SEPARATOR IF INDICATED

IN EXPANSION TANK SCHEDULE.

5. RELIEF VALVE FOR CHILLED WATER SYSTEM IS

SHOWN. OMIT WHEN RELIEF VALVE IS SHOWN ON

NOTES:

1. UNLESS OTHERWISE SHOWN ON THE DRAWINGS, SIZE THE VENT PIPE SO THAT STEAM IS NOT BLOWN OUT AT THE VENT PIPE ENTRANCE. UTILIZE THE CALCULATION METHOD CONTAINED IN ANSI B31.1 POWER PIPING CODE, APPENDIX II. THE VENT PIPE SHOULD GO VERTICAL THRU THE ROOF WITH NO TURNS OR ANGLES. WHERE REQUIRED THERE SHALL BE NO MORE THEN A TOTAL OR 180 DEGREES IN DIRECTIONAL CHANGES MADE WITH 45 DEG. ELBOWS.

2. VENT PIPE SHALL TERMINATE 1829mm [6"] MIN. ABOVE FINISHED ROOF.

3. DISCHARGE OF DRAIN SHALL BE DIRECTED AWAY FROM PLATFORMS OR OTHER AREAS WHERE PERSONNEL MAY OCCUPY.

4. DO NOT CONNECT ANY OTHER DRAIN TO THE DRIP PAN ELBOW DRAIN PIPE.

NOTES:

1. WHEN COIL IS INCLUDED IN CASING MOUNTED ON VIBRATION

ISOLATOR UNITS, THE RUNOUT PIPING FOR CONNECTIONS TO

COIL SHALL BE INSTALLED WITH SWING JOINTS TO ALLOW FOR

THE VIBRATION.

2. PIPING SHALL BE INSTALLED IN SUCH MANNER THAT IT WILL NOT

BLOCK THE SWING OR USE OF ACCESS DOORS OR PANELS;

NEITHER SHALL IT BLOCK THE SERVICING OF FILTERS, VALVES,

OR EQUIPMENT.

3. TRAP EACH COIL SEPARATELY WHEN INSTALLED IN A BANK OF

TWO OR MORE HIGH. ALSO PROVIDE SEPARATE VACUUM

BREAKER FOR EACH COIL.

4. TWO TRAP ASSEMBLIES IN PARALLEL ARE SHOWN. TWO TRAPS

REQUIRED WHEN CONDENSATE LOAD IS 2400 KG/HR [5,000
