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.

2. Cover the refrigerant pipe well with an insulator.
- It prevents the water, on the outer surface of the pipe, from dripping and increase the efficiency of the DVM Hydro unit.
3. Cut off the leftover insulator.
4. Check for cracks on the bent part of the pipes.
5. When the DVM Hydro unit is installed in a hot and humid place, water may form on the outer surface of the insulator so it
would be necessary to double the insulation thickness (10mm or more).

Refrigerant pipe work on DVM Hydro unit HT
DVM Hydro unit HT has refrigerant pipes of two different types.
f Liquid side pipe
f Gas side pipe
f Make sure there are no foreign substances and impurities in the pipe.
t There is no nitrogen gas inside of connected pipes of Hydro unit HT and the outdoor unit.
t DVM Hydro unit HT is using the new refrigerant, R-134a. The connected pipes of Hydro unit HT and the outdoor
unit are using R-410A
t The product performance or reliability can have grave consequences.
t The design pressure is 4.1 MPa, and make sure to consider selecting the refrigerant pipes which meet the
standard(material, thickness)
t Make sure to use liquid refrigerant when charging the refrigerant, because the using refrigerant is mixture
refrigerant.
❋ DVM Hydro unit HT is using heat exchanger of plate type, and make sure to consider installation location to
connecting water pipes.
CAUTION
1. Remove the safety cap of the refrigerant pipe and fasten the nuts after
connecting refrigerant pipes to each port of the Hydro unit HT.
f Make sure to fasten the nut using hand of person first, after that use tools
like torque wrench and spanner.
