Figure 6-33 Water-Cooled Condenser Cleaning -- Gravity Circulation; Table 6-1 Ambs, Dts, Rrs, Rts, Srs And Sts Temperature-Resistance Chart - Carrier 69NT40-511-1 Operating And Service Manual

NOTE
If the condenser cooling water is not being used
as drinking water or is not re-circulated in a
closed or tower system, neutralizing is not
necessary.
11. Put the unit back in service and operate under
normal load. Check the head pressure. If normal, a
thorough de-scaling has been achieved.
What You Can Do For Further Help:
Contact the Engineering and Service Department of the
OAKITE PRODUCTS CO., 19 Rector Street, New
York, NY 10006 U.S.A. for the name and address of the

Fill condenser with
cleaning solution. Do
not add solution more
rapidly than vent can
exhaust gases caused
by chemical action.
