Before Using This Unit
Installation Procedure
1 Release the stopper lock of the casters.
(CLH400/600)
Push down the stopper button of the casters as
shown in the right figure. It will be unlocked.
(Only the two casters on the front side of the unit
are equipped with a caster.)
The model CLH301 is equipped with rubber feet.
2 Move the unit to the place of installation.
™ If there is a bump on the floor, the casters may receive excessive load and get damaged. In this
case, lift and move the unit.
3 After the unit is placed in the desired position, lock the stopper button of the casters.
4 Check the drain cock.
Confirm that the drain cock on the right side of
the unit is in the "Close" position (perpendicular
to the cock).
5 Connect the hoses.
• Securely connect the hoses to the ports of the unit and the external water tank of the external
open system so that the fluid does not leak. See the figure shown below. The outside
diameter of both discharge (OUT) and return (IN) ports is each 13 mm.
Note) Connect the priming pump port (IN) to the return (IN) port of the unit.
• Using a solenoid or throttle valve to shut off the circulating path may result in malfunction of the
circulating pump or fluid leakage.
• Do not throttle the path excessively. Keep a flow rate of the circulating fluid at 1.5·/min or over.
• Slowly change the flow rate. A rapid change in the flow rate may reduce the service life of the
circulating pump.
