Specific Product Precautions 3
Be sur e to read t h is bef or e h andlin g t he p roducts . Refe r to th e b a ck c o ve r f or sa f ety instructions. For temperature control
equipment precautions, refer to the “Handling Precautions for SMC Products” and the “Operation Manual” on SMC website:

Piping
Caution
1. Regard i ng the ci rculatin g f lu i d pi ping, c ons i der
careful l y the suitability f or tem p erature and
ci rculating fluid.
If the operating performance is not sufficient, the pipings may burst
during operation. Also , the use of corrosive materials such as alu-
minum or iron for fluid contact parts , such as piping, may not only
lead to clogging or leakage in the circulating fl uid circuit but also
refrigerant leakage and other unexpected problems. Provide
protection against corrosion when you use the product.
2. Selec t the piping p ort s ize w hich can excee d the
rated flow .
For the r ated fl ow , re fer to the pump capacity table.
3 . Whe n t igh t e n i n g at th e drain p ort o f t h is p rodu c t,
use a pipe wren c h to c lamp the connection ports.
4. For the ci rculating fluid piping connection, install a
drain pan and wast e water collection pit just in case
the circulating fluid may leak.
5. Th is p roduct series ar e c onstant-tem p eratur e fl uid
ci rculating ma c hines with b uilt-in tanks.
Do not install equipment on your system side such as pumps
that forcibly return the circulating fluid to the unit. Also , if you
attach an external tank that is open to the air , it may become
impossible to circulate the circulating fluid . Proceed with caution.

the maintenance and ventilation.
<Ai r-cooled refri g eration>
1. The air-cooled type product exhausts heat using the fan that is
mounted to the product. If the product is operated with insuf fi -
cient ventilation , ambient temperature may exceed 45
°
C , and
this will affect the performance and life of the product. To pre-
vent this ensure that suitable ventilation is available (see below).
2. For installation indoors , ventilation ports and a ventilation fan
should be equipped as needed.

3. If it is impossible to exhaust heat from the installation area in-
doors , or when the installation area is conditioned , provide a
duct for heat exhaustion to the air outlet port of this product for
ventilation. Do not mount the inlet of the duct (flange) directly to
the air vent of the product, and keep a space larger than the di-
ameter of the duct. Additionally , consider the resistance of the
duct when making the air vent port for the duct.
