1. SELECTING THE INSTALLATION LOCATION
(1) Install the gas heat pump A/C so that it satisfi es all local regulations and government safety codes, as well
as installation standards and service guidelines for industrial gas devices.
(2) Choose a suitable installation location (with adequate space for servicing), as below.
• Install the outdoor unit in a location where exhaust gases will not enter the building's air intake or exhaust
vents or windows, and will not enter the building through tubes or vents that lead inside the building. There
is danger of poisoning if exhaust gases enter the building.
• Install the outdoor unit outdoors, in a location open to the air, so that there is no accumulation of exhaust gases.
There is danger of the gases entering the building and causing poisoning.
• The exhaust gases must be open to the air in a location where they will not adversely affect the surroundings.
There is danger of exhaust gases entering the building and causing poisoning. (Be certain not to allow
exhaust gases to be discharged into a drainage basin, gutter, or similar location.)
• Install the outdoor unit securely in a location that can fully bear the weight of the unit.
There is danger of gas leakage or injury if the outdoor unit tips over or falls.
• The allowances shown in Fig. 1 are for the space required for maintenance work. Be sure to provide this
minimum space when selecting the location of the unit.
Failure to do so may result in injury caused by the outdoor unit tipping over during maintenance, or in
diffi culty in servicing the unit.
• If the outdoor unit is installed on a roof or other elevated location, install a permanent ladder, handrails,
and other necessary items in the passageway leading up to the unit, and install a fence, handrails, or
similar structure around the outdoor unit. Failure to do so may result in injury caused by the unit tipping
over during maintenance.
• Be sure to stand on a stable surface when installing the outdoor unit on an elevated base or location, and
avoid using stepladders.
• Leave the distances shown in Fig. 2 between the outdoor unit and any fl ammable materials.
There is danger of fi re if these distances are insuffi cient.
• Do not install the outdoor unit in a location where fl ammable gases may be generated, fl ow, accumulate
or leak, or in a location where volatile substances are handled or stored. There may be danger of fi re or
explosion if the unit is installed in such a location.
• Install the outdoor unit in a location where exhaust gases and fan air will not harm plants or animals.
The exhaust gases and fan air may adversely affect plants and animals.
• Avoid installation near locations such as parking lots and fl owerbeds where damage from clinging dust
and particles may occur. If installation in such locations is unavoidable, be sure to put a covering on the
outdoor unit or take other measures to protect it.
In addition to heeding the WARNING and CAUTION notes, avoid installation in locations where the unit will be
exposed to the following:
• excessive dust
• excessively salty air, such as near the sea
• sulfuric gases, such as near hot springs
• excessive water, vapors, or oil fumes (ex: from machines)
In order to improve heat exchange, install the outdoor unit in a location that is well ventilated. The spaces for each
part must be as shown in Figs. 1 and 2.
If installing in a poorly ventilated location, or if installing multiple outdoor units, ensure suffi cient space to prevent
short circuits.
• fumes from organic solvents
• high fl uctuations in power voltage
• electromagnetic interference from other devices
