Pressurize and Operate
As shown in Figure 9d, close the flush cart return valve
to pressurize the loop to at least 50 psi [517 kPA]. After
pressurizing, close the flush cart supply valve to isolate
the flush cart. Move the Fluid cooler water in and water
out valves to position D.
If the loop pressure is between 50 and 75psi [345 to
517 kPa] upon completion of flushing, pressure should
be sufficient for all seasons.
Unhook the flush cart from the fluid cooler. Install caps
on the fluid cooler water inlet and outlet to prevent and
leaks.

NOTICE:
It is recommended to run the unit for 15-20
minutes to ‘temper’ the fluid temperature and prepare
it for pressurization. This procedure helps prevent the
periodic “flat” loop condition of no pressure.
