Bell & Gossett V1001576 Suction Diffuser Plus - Manual (Page 17)

If the component or Suction Diffuser Plus appears to have been damaged, replace it.
3. Starting with the second thread of the male Suction Diffuser Plus component, apply a
360º bead of Loctite 567 thread sealant/lubricant as shown. Follow Loctite handling
precautions as noted on the product label.
4. If Loctite is not available, it is recommended that you use RectorSeal No. 5 pipe thread
sealant for all non-glycol based applications, or any PTFE thread sealing tape. Be sure
to follow the manufacturer-specific handling precaution and application instructions
as noted on the product label.
5. Thread component into the Suction Diffuser Plus until it is finger tight.
6. Thread component into the valve until it is finger tight.
7. Apply torque to the following specification:
Size Type Torque, ft-lbs Torque, Nm
1/4” P/T Readout Port 9.0 ft-lbs. + 3.0 ft-lbs. / 0 12.2 Nm + 4.1 Nm / 0
3/4” Drain plug 72.0 ft-lbs. + 21.0 ft-lbs. / 0 97.6 Nm + 28.5 Nm / 0
NOTICE:
The use of thread sealants and lubricants on threads also provides lubricity. Over-
application of torque can damage the Suction Diffuser Plus port or component.
8. Properly assembled Suction Diffuser Plus components will immediately seal to
moderate pressure (6 bar [100 PSI] or less). For maximum pressure resistance, allow
the Loctite 567
1 or RectorSeal No. 5 2 thread sealant to cure for 24 hours. PTFE tape
typically does not require curing to achieve maximum pressure resistance.
