2. Select the Best Location

1. Select space for installing unit, which will meet the following conditions:
• No direct thermal radiation from other heat sources
• No possibility of annoying neighbors by noise from unit• No exposition to strong wind
• With strength which bears weight of unit
• Note that drain flows out of unit when heating
• With space for air passage and service work shown next
• Because of the possibility of fire, do not install unit to the space where generation, inflow, stagnation, and leakage of
combustible gas is expected.
• Avoid unit installation in a place where acidic solution and spray (sulfur) are often used.
• Do not use unit under any special environment where oil, steam and sulfuric gas exist.

high humidity in winter (near beach, coast, lake, etc).
(Ex) Rooftop where sunshine always shines.
• Performance of heating will be reduced and preheat time of the unit may be lengthened in case of installing the unit in
winter at following location:
- Shade position with a narrow space
- Location with much moisture in neighboring floor.
- Location with much humidity around.
- Location where ventilation is good.
It is recommended to install the unit at a place with a lot of sunshine as possible as.
