CAUTION
•In regions with heavy snowfall, make sure to install
the DVM CHILLER where there is no concerns of
direct snowfall on the DVM CHILLER. Also, build
higher base support so that accumulated snow does
not block the air inlet or the heat exchanger.
•R-410A refrigerant is a safe, nontoxic and
nonammable refrigerant. However, if the place
holds any concerns for exceeding dangerous level
of refrigerant concentration in case of refrigerant
leakage, extra ventilation system is required.
•When you install the product in a high places such
as roof, install fence or guardrail around it. When
there is no fence or guardrail, service person could
fall.
•Do not install the product in places where corrosive
gases such as sulfur oxides, ammonia, and sulfurous
gases are produced. (e.g. Toilet outlet, ventilation
opening, sewage works, dyeing complex, cattle
shed, sulfuric hot spring, nuclear power plant, ship
etc.) When installing the product in those places,
contact an installation specialty store as the copper
pipe and brazing part will need additional corrosion
proof or anti-rust additive to prevent corrosion.
•Make sure to keep any inammable materials (such
as wooden materials, oil etc.) around the DVM
CHILLER. When there's re, those inammable
material will easily catch the re and may pass it on
to the product.
•Depending on the condition of power supply,
unstable power or voltage may cause malfunction
of the parts or control system.
(At the ship or places using power supply from
electric generator, etc.)

•Make sure to remove the wooden pallet before
installing the DVMCHILLER. If you do not remove
the wooden pallet, there is risk of re during
welding the pipes. If the DVMCHILLER is installed
with wooden pallet on, and it was used for long
period time, wooden palette may break and cause
electrical hazard or high pressure may damage the
pipes.
•Fix DVMCHILLER rmly on the base ground with
anchor bolts.
CAUTION
•Manufacturer is not responsible for the damage
occurred by not following the installation standards.
1 Make sure that the height of the base ground is
200mm or higher to protect the product from rain
water or other external conditions. Also, install
a drainage hole around the supporting base and
connect the drain pipe to the drainage pit.
2 Considering the vibration and weight of the product,
strength of the base ground must be strong to
prevent noise and the top surface of it should be at.
3 Area of the base ground should be 1.5 times larger
than the bottom of the product.
4 Product must be xed rmly so that it can withstand
the wind speed of 30m/s. If you cannot x the
DVMCHILLER on the supporting base, x it by side
or use extra structure.
5 In heating operation, defrost water may form
so you must really care about the drainage and
waterproong the oor. To prevent defrost water
from stagnating or freezing, construct a drainage pit
with over 1/50 slant. (Ice may form on the oor in
the winter time.)
6 It is necessary to add wire mesh or steel bar during
concrete construction for the base ground to prevent
damage or cracks.
7 When installing multiple DVM CHILLERs at the same
place, construct an H beam or a vibration-isolation
frame on the base ground to install the product.
8 After installing an H beam or a vibration-isolation
frame, apply corrosion protection and other
necessary coating.
9 When concrete construction for product installation is
complete, install an isolation pad (t = 20 mm or more)
or a vibration-isolation frame to prevent vibration of
the product from transferring to the supporting base.
10 Place the product on an H beam or a vibration
isolation frame and x it with the anchor bolt, nut
and washer. (The bearing capacity of the anchor bolt
has to be over 3.5 kN)
