Selecting installation location
Decide the installation location regarding the following condition and obtain user’s approval .
Standard installation condition
f
f
Heat source water containing foreign substances can cause condenser and pipe corrosion as well as water scale .
Therefore, make sure that water source meets the standard of cooling water quality for refrigerating and air conditioning
equipment . (Refer to 'Cooling water management' on page 103 .)
f
f
Closed circuit cooling tower must be used, but when open cooling tower is in use, select indirect water pipe installation
method which water pipe of the building is not directly connected to the water pipe of the product .
f
f
Strainer (which needs to be purchased separately) must be installed to the ‘Water In’ pipes of the heat source water . If
sand, dust or rust debris enter to water system, it may cause corrosion on metallic materials or blockage of the water heat
exchanger and damage the heat exchanger .
f
f
DVM S WATER-GEO air conditioner is not designed to be installed outdoor . There are risk of burst and frozen water pipes
when the outdoor unit is installed outdoor, therefore it must be installed indoor (machine room etc .)
Installation location condition
f
f
Choose a place with ventilation duct or opening to cool down the heat generated from the product and maintain the
surrounding temperature within 0~40°C and the humidity below 80% .
f
f
Choose a place where structure can bear the weight and vibration of the outdoor unit .
f
f
Choose a flat place that rainwater does not settle or leak .
f
f
Choose a well ventilated place with sufficient space for repair and other services .
f
f
Choose a place where you can easily connect the refrigerant pipes between indoor and outdoor units within allowable
distance .
f

This product is not salt tolerant, therefore do not install it near the sea or hot springs where outdoor unit may corrode .
•
R-410A refrigerant is a safe, nontoxic and nonflammable 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 .
•
Do not install the product in a place with corrosive gas such as sulfur oxides, ammonia gas, sulfurous gases .
Example: near washroom exhaust pipe, ventilation duct outlet, or surface near hot spring etc . (Copper pipes and
soldered parts may corrode and cause refrigerant leakage .)
•
Install the product in a place without any risk of inflammable gas leakage .
•
System air conditioner can be interfered with static noise when listening to AM radio . Therefore, select a location
where indoor unit can be installed while keeping optimal distance from the radio, computer, stereo equipment .
Furthermore, select a location where electrical wiring work is possible and put those wires in a individual
protection tubes and ground those protection tube .
- Especially, keep the unit at least 3 m away from the electrical equipment in an area with weak electromagnetic
waves and put the main power cable and communication cables in separately installed protection tubes, and
ground each protection tubes .
- Make sure that there is no equipment that generates electromagnetic waves . If not electromagnetic waves
may cause problem to the control systems which may lead to air conditioner malfunction . (Example: Remote
control sensor of the indoor unit may not be received well, due to ballast stabilizer of the lighting equipment .)
