4. Outdoor unit configuration

The unit (PUHY-600/650/700/750YSMC) consists of a combination of variable capacity units (PUHY-400/500YMC) and constant capacity units (PUHN-

200/250YMC). A CMC-30A (optional) is required when using a combination of these units.

5. Selection of installation site

Select space for installing outdoor 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 below

Because of the possibility of fire, do not install unit to the space where generation, inflow, stagnation, and leak of combustible gas is ex- pected.

Avoid unit installation in a place where acidic solution and spray (sulfur) are often used.

When having cooling operation at an outside air temperature of be- low 10 °C, in order to obtain steady operation of unit, select an instal- lation site not exposed directly to rain and snow, or install air outlet and inlet ducts. (Refer to Page 11.) Install the outdoor unit at the same position on the same floor, or above, the indoor unit. (See the figure at the right.)

Do not use unit in any special environment where oil, steam and sulfuric gas exist.

Installation restriction on outdoor unit when cooling operation is performed when the outdoor air temperature is 10 °C or lower.
