Preparation for Operation

7-1
7 Preparation for Operation
7.1 Preparation for circulating fluid
The piping for circulating fluid is
connected as below.
1. The piping for circulating fluid
is located at the left side face.
2. The same fittings are used for IN and OUT of the
circulating fluid.
The fitting which can mate them needs to be prepared separately. When the fitting is connected, be
sure to hold the fitting (block) mounted at Thermo-con with spanner, etc.
Thread size of fitting for circulating fluid:
HEC002-A; Rc1/4
HEC006-A; Rc3/8
A plug is mounted on DRAIN port for circulating fluid. When the
piping for drain is connected, remove this plug beforehand.
Drain the circulating fluid before performing any
maintenance.
Width across flat of plug: 6mm
DRAIN port size: Rc1/4
Fluid other than water is not to be used as circulating fluid. Using such a
fluid might lead to fluid leakage and damage of the pump.
If a tank released to atmosphere is mounted outside, minimize the
piping resistance at RETURN of circulating fluid. If the piping
resistance is high, the causing the built-in reservoir of Thermo-con can
have negative pressure resulting in deformation and crack. The built-in
reservoir of Thermo-con is made of plastic and must not be subject to
negative pressure larger than -0.02MPa.
Once the plug is removed from the drain port, the leakage from it is not
guaranteed. Therefore, seal it with PTFE seal tape etc. and ensure there
is no leakage from it before operation.
