Note
Keep in mind that an over application of solder can result in solder balls falling in to the associated pip-
ing with the possibility of water flow restriction and/or blockage. Also, an under application of solder can
result in water leakage paths between the common surfaces of the fitting being soldered.

Note
A soldering combination of silver bearing solder, i.e. Harris (not Harris Broadcast) Stay-Brite R (086-
0004-038), and “Stay Clean” liquid soldering and tinning flux (086-0004-040) or equivalent, is recom
-
mended. Also, pipe thread joints should be conditioned with Teflon tape (299-0018-000) and a thin film
application of a smooth, non-hardening thread sealing, compound with integrated Teflon is recommended,
i.e. Locktite #565, or “Gasoila” (690-0017-000), prior to mating any two threaded pieces together.

Caution
IF FREEZING CONDITIONS EXIST DURING CHECKOUT AND FLUSHING
PROCEDURES, FLUSHING PROCEDURE AND SUBSEQUENT FILL WITH
FINAL GLYCOL/WATER MUST BE FINISHED BEFORE STILL WATER IS
ALLOWED TO REMAIN IN HEAT EXCHANGER. IF PROCEDURE CANNOT BE
FINISHED, CARE MUST BE TAKEN TO PREVENT WATER FROM FREEZING
IN OUTSIDE COOLING SYSTEM EQUIPMENT. IF WATER REMAINS IN
OUTSIDE EQUIPMENT LONG ENOUGH TO FREEZE, THE UNITS WILL BE
DAMAGED. PUMP A MIXTURE OF GLYCOL/WATER INTO OUTSIDE
EQUIPMENT TO PREVENT DAMAGE.
