Choose proper external piping with consideration for pressure,
temperature and compatibility with the circulating fluid. Potential pipe
rupture during operation may occur if disregarded.
Always insulate external circulating piping. Potential insufficient
cooling performance due to heat absorption from the pipe surface and
potential insufficient heating performance caused by thermal radiation
if disregarded.
Use clean pipes and pipe fittings, free of particles, oil and moisture.
Apply air blow to the parts before using. The presence of particles, oil
or moisture in the circulating fluid circuit can cause insufficient
cooling, product failure attributed to moisture freezing, or foaming of
the circulating fluid in the tank.
The total capacity of circulating fluid required by external piping
should remain under the capacity of the sub tank. Potential problem of
tank overflow, when pump stop, may occur if disregarded. See
“Appendix 8.1.1 Product specification” in Chapter 8 for the capacity of
the sub tank.
Be sure to choose a circulating fluid pipe capable of letting the fluid
flow at rated flow rate or better. See “Pump performance” defined in
“Appendix 8.1.1 Product specification” for the flow rate rating.
Have a drip pan available in case of a fluid leak.
Make sure of the locations of ports for the circulating fluid supply,
return,
facility water inlet, outlet and their corresponding connections
are correct.
Secure the piping connector section with a pipe wrench, and provide
proper tightening torque to the pipe.
Avoid physical shock when securing and tightening the connectors.
Potential breakage and fluid leak may occur if disregarded.
