Procedure 1
Confirm that a nut, a ferrule, and an insert are installed at the end of the DI tube for IN (Fig. 1). Insert the DI tu
be
for IN to the end of the DI circuit Supply, and tighten the nut by hand. At that time, use two spanners, (1) and (2
),
not to rotate the self-align fitting. Turn the hand-tightened nut by 1/4 rotatio
n.

Circulating fluid Supply
Circulating fluid Return
- It is possible to control the electric resistance of circulating fluid as you like by using an ion exchange resin filt
er
(hereafter DI filter) and electric resistance meter (hereafter DI sensor
).
- DI filter is not attached. Purchase our HRZ-DF001 separately if you need. If the DI filter is used at temperature out
of
the range, 20 to 40degC, also purchase a thermal insulator, HRZ-DF002, to prevent frostbite and a bur

Procedure 4
Supply circulating fluid from IN side of the DI filter to exhaust air. Continue to supply until OUT side is fill
ed
with circulating fluid.

Procedure
3
Mount a therml insulator for DI filter as shown at Fig. 2, and set it in the drain pan (only for the customers who purchas
ed
it).
Procedure 5
Connect the DI tube for OUT and DI tube for IN to OUT side and IN side of the DI filter respectively. As the
DI
tube has a strainer and a packing at the DI filter connection part, be careful not to drop them (Refer to Fig. 3
).
Procedure 6
Perform trial operation in accordance with Thermo Chiller operation manual, HRX-OM-K003. Initially, the
DI
filter has water. If ethylene glycol solvent is used, the concentration may be decreased. Confirm the concentrati
on
after the trial operation. The proper concentration of ethylene glycol is 60%. If no leakage is found, install
a
insulator to a ball valve connected to the DI tube, and fix it with a band
(Refer to Fig. 4).

- Perform installation work without any circulating fluid in Thermo Chiller.
Perform the work before supplying circulating fluid in or after exhausting all the circulating fluid fr
om
Thermo Chiller. The circulating fluid shoud be exhausted after the fluid gets to be ambient temperatur
e.
Otherwise, an operator may get a burn or frostbite.
- Do not perform installation work while power is on.
Perform lock-out and tag-out of the power securely. Otherwise, Thermo Chiller may operate unexpectedl
