When the installer has decided on the final configuration, the appropriate fittings and flowmeter
assembly are deburred, cleaned and assembled as shown in the example illustrated in Figure 4.
Figure 4. Soldering Heat Protection
Before soldering:
IMPORTANT
Be certain that the flowmeter is oriented with the arrow pointing in the direction
of water flow into the compressor unit. Be certain that the 5” downstream
piping assembly is at the “arrow end” of the flowmeter assembly.
IMPORTANT
Protect the flowmeter with a cold wet cloth and a flame shield before soldering
joints nearest the flowmeter body. Also, protect the compressor cabinet paint
from the torch flame with a flame shield. See examples in Figure 4.
After soldering the joints for the flowmeter piping assembly, let them cool and then apply water
pressure to the assembly and check to see that all joints are sealed.
Purge the system of air prior to operating the compressor unit water pump.
