Transportation/Movement/Installation
Caution
Radiation Air
Caution
1. The inlet for radiation air must not be exposed to
particles and dust as far as possible.
2. Do not let the inlet and outlet for radiation air get closed.
3. If more than one thermo-con is used, consider their
arrangement so that the downstream sides of the thermo-
cons suck radiation air from the upstream sides.
Otherwise, the performance at the downstream sides may
deteriorate. Also, the set temperature may not be achieved
depending on the value of the set temperature and the load. In
such a case, take countermeasures such as changing the
direction of the thermo-cons to prevent the deterioration of
performance.
4. A filter is built in. Clean the filter periodically.
1. Use a fluid that is listed in the specifications.
2. Deionised water (pure water) [with an electric conductivity
of approx. 1
μ
S/cm] can be used, but may lose its electric
conductivity.
Also, if a facility supplying deionised water (pure water) is used,
the thermo-con may be damaged by static electricity.
3. If deionised water (pure water) is used, bacteria and
algae may grow within a short period.
If the thermo-con is operated with bacteria and algae present,
its cooling capacity or the capacity of the pump may deteriorate.
Replace all deionised water (pure water) regularly according to
the conditions (once a month as a guide).
4. If using a fluid other than those listed in the specifications,
please contact SMC beforehand.
5. The max. operating pressure of the resin tank is 0.1 MPa.
If this pressure is exceeded, leakage from the tank in the
thermo-con may result.
6. Select piping length and diameter to allow the
circulating fluid flow rate of 0.5 l/min or larger.
If the flow rate is less than these values, the thermo-con will not
be able to provide precise control, and the repeated cooling and
heating operations may cause it to fail.
7. A magnet driven pump is used as the circulating pump.
Fluids which contain metal powders such as iron powder cannot be used.
8. The thermo-con must not be operated without circulating
fluid.
The pump can break due to idling.
9. If the tank lid is opened after the supply of circulating
fluid, the circulating fluid may spill out depending on
the condition of the external piping.
10. If an external tank is used, the circulating fluid may
spill out from the internal tank lid depending on
where the external tank is installed.
Confirm that the internal tank has no leakage if using an
external tank.

Caution
Design
Warning
1. Thiscatalogue shows the specifications of the thermo-
con.
1. Check the detailed specifications in the separate “Product
Spe cifications”, and evaluate the compatibility of the thermo-
con with customer system.
2. Although a protection circuit as a single unit is installed, the
user is requested to carry out a safety design for the whole
system.

Specific Product Precautions
Be sure to read this before handling the products. Refer to the back cover for safety instructions.
For temperature control equipment precautions, refer to the “Handling Precautions for SMC
Products” and the “Operation Manual” on the SMC website: https://www.smc.eu
Handling
Warning
1. Thoroughly read the operation manual.
Read the operation manual completely before operation, and
keep the manual where it can be referred to as necessary.
2. If the set temperature is repeatedly changed by 10
°
C
or more, the thermo-con may fail in short periods of
time.
Operating Environment/Storage Environment
Warning
1. Keep within the specified ambient temperature and
humidity range.
Also, if the set temperature is too low, condensation may form
on the inside of the thermo-con or the surface of piping even
within the specified ambient temperature range. Dew
condensation can cause failure, and so must be avoided by
considering operating conditions.
2. The thermo-con is not designed for clean room usage.
The pump and fan generate dust.
3. Low molecular siloxane can damage the contact of
the relay.
Use the thermo-con in a place free from low molecular siloxane.
