• Caution for welding the pipe to a DVM Hydro unit
- When welding the pipe to the product, the unit may get damaged by the heat and flame from welding. Use a
flame proofing cloth to protect the unit from a brazing fire or flame.
- Wrap the pipe with a wet cloth and weld it as shown in the illustration. Also, water dripping from the wet cloth
may interrupt the welding so make sure the water does not drip from the wet cloth.
- Make sure that connected pipes of DVM Hydro unit and the outdoor unit does not interrupt each other or make
contact with the product. (Vibration may cause damage to the pipes.)
- When removing the sealed pipe on the bottom side of the service valve, cut it with a pipe cutter first and then
start the welding.When the sealed pipe is welded without cutting, you may get injured by the refrigerant
within the pipe.
CAUTION
1. Remove the copper cap of the refrigerant pipe and eliminate the sludge or foreign substances on the welded part and
then weld the connecting pipe on each port.
- Since nitrogen gas is sealed within the pipe, you must discharge the nitrogen gas from the liquid pipe.Then remove the
copper cap and check for existence of the nitrogen gas.
- Check the pressure of the nitrogen gas before welding. If the nitrogen gas is not being purged, product is not normal so
do not install it.

4) Water pipes must be equipped with valves and other instrumentations as shown in the diagram. Strainer and
flow switch must be installed within 1~2m from the entrance pipe of the DVM Hydro unit.
- When strainer is not installed, sand, dust or rust debris may cause product breakage.
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 must be installed indoor at room temperature and the water inlet and outlet must be insulated
with the heat exchanger as shown in the diagram.
7) Damp-proof, cold reserving and insulation work must be done 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 and may get property damage during cold
seasons when water pipe freezes and bursts. This product will keep the circulation pump to operation in certain
interval, even when the power is off, in order to prevent pipe rupture. Therefore, you must check if the power
(220~240V) is being supplied.
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 is under 0°C. 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.
- Drain remaining water in the water pipe
- Install self-regulating heat cable on the water pipes
- If the product is installed in a place where surround temperature drops below 0°C, 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.

fWhen the amount of cooling water is out of the operation range, stop the DVM Hydro unit and take care of the cause
before re-start the operation.
fTemperature 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.
11) Water scale may occur on the plate type heat exchanger depending on the water quality and the type of plate heat
exchanger so regular chemical cleaning is necessary. When installing water pipes, install a heat source water shut-off
valve and also install the flushing pipe with a ball valves (for chemical cleaning) on the pipe installed between the
shut-off valve and the outdoor unit.
12) Before trial operation, connect the cleaning pipes installed on inlet and outlet as shown in above illustration.Then,
take appropriate measures (such as blind flange etc) to stop the circulation water from entering the outdoor unit
plate type heat exchanger, and use circulating pump to remove foreign substance within the water pipes and clean
the strainer. If you do not clean the strainer, foreign substances may accumulates on plate type heat exchanger and
may break the heat exchanger or cause problem to it.
13) Make sure that water quality within the water pipe meets the standard of cooling water quality for refrigerating and
air conditioning equipment.
- Heat source water containing high level of foreign substances can cause water heat exchanger and pipe corrosion or
creation of water scale. (Use the appropriate heat source water according to the below table)
- If the make-up water is provide from any other source than local water supply, make sure to check the quality of water.
- Strainer (which needs to be purchased separately) must be installed to the‘Water IN’pipes of the water pipe. If sand,
dust or rust debris enters to water system, it may cause corrosion on metallic materials or blockage of the water heat
exchanger and damage the heat exchanger.
- If the existing thermal storage tank or pipes are used, foreign substances may block the plate type heat exchanger of
the DVM Hydro unit so, water quality and foreign substances must be managed.
