6. SELECTING AN INSTALLATION LOCATION
General precautions on outdoor installation location
Select an installation site that meets the following requirements and
that meets with your customer's approval.
■ The unit is designed to be installed in an outdoor location.
■ The space around the unit is adequate for maintenance and
servicing (refer to "7.3. Service space" on page 10).
■ The space around the unit allows for sufficient air circulation.
There must be sufficient space for air passage and no
obstructions around the air intake and the air exhaust (see
"Installing near a wall or obstacle" on page 9).
■ There must be sufficient space for carrying the unit into and out
of the site.
■ There is no danger of fire due to leakage of inflammable gas.
The site must be free from the possibility of flammable gas
leakage in a nearby place.
■ The equipment is not intended for use in a potentially explosive
atmosphere.
■ Choose a place solid enough to bear the weight and vibration of
the unit, where the operation noise will not be amplified.
■ All piping lengths and distances have been taken into
consideration.
■ Since drain flows out of the unit, do not place anything under the
unit which must be kept away from moisture.
■ Take care that in the event of a water leak, water cannot cause
any damage to the installation space and surroundings (e.g. in
case of a blocked drain pipe).
■ Install the unit and power cords at least 3 m away from television
and radio sets. This is to prevent interference to images and
sounds.
Depending on radio wave conditions, electromagnetic
interference may still occur even if installed more than 3 m away.

WARNING
Be sure to provide for adequate measures in order to
prevent that the EBHQ outdoor unit be used as a shelter by
small animals.
Small animals making contact with electrical parts can
cause malfunctions, smoke or fire. Please instruct the
customer to keep the area around the EBHQ outdoor unit
clean and clear.
CAUTION
Appliance not accessible to the general public, install it in a
secured area, protected from easy access.
This unit, both indoor and outdoor, is suitable for
installation in a commercial and light industrial
environment.
Requirement Value

supplied with the domestic hot water tank is
12 m in length (to be connected to the
indoor unit EKCB).
10 m
Maximum allowable distance between the
3-way valve and the outdoor unit (only for
installations with a domestic hot water tank
installed)
