13. Installation
3) Use certified parts for water pipe system and the water pressure of the water pipe system connected to outdoor
unit must remain under 1.0 MPa (145.0 psi). Use copper or stainless pipe water pipe.
4) Water pipes must be equipped with valves and other instrumentations as shown in the diagram. Strainer must
be installed within 1 ~ 2 m (3.3 ~ 6.6 ft) from the entrance pipe of the DVM Hydro unit / Hydro unit HT.
a) When strainer is not installed, sand, dust or rust debris may cause product breakage.
b) Make sure that the strainer mesh is made of stainless steel.
5) Water inlet pipe is located at the bottom part of the heat exchanger and the water outlet pipe is at the top part
of the heat exchanger.
6) DVM Hydro unit / Hydro unit HT must be installed indoor at room temperature and the water inlet and outlet
must be insulated as shown in the 'Water pipe installation system' diagram.
7) Insulation work must be done properly and thoroughly to prevent condensation from forming on the surface of
the product and drain pipes of indoor/outdoor units. When the necessary work is not done thoroughly, you will
waste energy caused by thermal loss. In cold applications pipes may freeze and burst causing property damage.
8) If you stop the product for long time or in night time, water pipe circuit may freeze naturally when the
temperature around the DVM Hydro unit / Hydro unit HT is under 0 °C (32 °F). When water pipe circuit freezes, it
will cause damage to the plate type heat exchanger and therefore preventive measure must be taken according
to the situation.
a) Drain remaining water in the water pipe
b) Install self-regulating heat cable on the water pipes
c) If the product is installed in a place where surround temperature drops below 0 °C (32 °F), use anti-freeze
accordingly for freezing point depression.
9) Install number of auto air discharge valve at a point where air may remain within the pipe (such as vertical water
pipe). If the air within the pipe is not discharged, it may cause performance decrease or corrosion on the product
or pipes.
10) Following is the operation range of water.

▶ When the amount of cooling water is out of the operation range, stop the DVM Hydro unit / Hydro unit HT and
take care of the cause before re-start the operation.
▶ Temperature of discharged water is very high so be careful not to come in contact with the body. Also, cover
the external water pipe with appropriate insulator for insulation and preventing burns.
