A set of thread adapters that converts the connections from Rc to NPT is
enclosed as an accessory. Be sure to use this for NPT piping.

A set of thread adapters that converts the connections from Rc to G is
enclosed as an accessory. Be sure to use this for G piping.

Connect piping firmly. Incorrect piping might cause leakage of
supplied or drained leakage and wet surrounding area and facility.

Pay attention not to allow dust and foreign materials to enter into
water circuit etc. during connection of piping.

During piping work, residual liquid may drip from the circulating
fluid circuit or facility water circuit. Prepare a drain pan near the
pipe connection so that the residual liquid can be received.

Hold the piping port firmly with specific wrench when tightening.

The piping should be selected with due consideraton of pressure
and temperature. Otherwise the piping can burst in service.

Use non-corrosive material for fluid contact parts of circulating
fluid and/or facility water. Also, the use of corrosive materials
such as aluminum or iron for fluid contact parts, such as piping,
may not only lead to clogging or leakage in the circulating fluid
and facility water circuits but also refrigerant leakage and other
unexpected problems. Provide protection against corrosion when
you use the product.

Do not generate a rapid change of pressure by water hammer etc.
The product and external piping might be damaged.

Facility water temperature of the facility water outlet port might
rise up to approx.60deg.C.
