Selecting The Installation Site - Sanyo Classic PAC i serie Einbauanleitung

Only the distribution joints are horizontal with respect
to the ground. The collective tubes are vertical with
respect to the ground.
The collective tube and distribution joint are
horizontal with respect to the ground.
Distribution joint
<Liquid tube side>
INCORRECT
Distribution joint insulation material (supplied)
• Use the supplied insulation material.
• The supplied insulation material include only a tape for
temporarily fastening.
• Use insulation material or other material to seal the
joining lines so that there are no gaps.
• Use vinyl tape or similar means to seal and fasten the
insulation materials in place.
Seal securely with vinyl tape (4 locations)
Refrigerant tubing (field supply)
Tubing insulation material
(field supply; thickness of more than 10 mm)
Tubing insulation material must be able to
withstand temperatures of at least 120°C.
Refrigerant tubing (field supply)
Collective tube
Be sure to install so that the tubes are
horizontal after the branch point.

2. SELECTING THE INSTALLATION SITE

2-1. Indoor Unit
CAUTION
● When moving the unit during or after unpacking, make
sure to lift it by holding its lifting lugs. Do not exert
any pressure on other parts, especially the refrigerant
piping, drain piping and flange parts.
● If you think the humidity inside the ceiling might exceed
30°C and RH 80%, reinforce the insulation on the unit
body. Use glass wool or polyethylene foam as insulation
so that it is no thicker than 10 mm and fits inside the
ceiling opening.
AVOID:
● areas where leakage of flammable gas may be expected.
● places where large amounts of oil mist exist.
● direct sunlight.
● locations near heat sources which may affect the
performance of the unit.
● locations where external air may enter the room directly.
This may cause "condensation" on the air discharge ports,
causing them to spray or drip water.
● locations where the remote controller will be splashed with
water or affected by dampness or humidity.
● installing the remote controller behind curtains or furniture.
● locations where high-frequency emissions are generated.
● places where blocks air passages.
● places where the false ceiling is not noticeably on an incline.
DO:
● select an appropriate position from which every corner of the
room can be uniformly cooled.
● select a location where the ceiling is strong enough to
support the weight of the unit.
● select a location where tubing and drain pipe have the
shortest run to the outdoor unit.
● allow room for operation and maintenance as well as
unrestricted air flow around the unit.
● install the unit within the maximum elevation difference
above or below the outdoor unit and within a total tubing
length (L) from the outdoor unit as detailed in Tables 1-8 and
1-10.
● allow room for mounting the remote controller about 1m off
the floor, in an area that is not in direct sunlight or in the flow
of cool air from the indoor unit.
● places where optimum air distribution can be ensured.
● places where sufficient clearance for maintenance and
service can be ensured. (See the next page.)
2-2. Outdoor Unit
AVOID:
● heat sources and exhaust fans, etc. (Fig. 2-4)
● damp, humid or uneven locations.
DO:
● choose a place as cool as possible.
● choose a place that is well ventilated and outside air
temperature does not exceed maximum 45°C constantly.
● allow enough room around the unit for air intake/exhaust and
possible maintenance. (Fig. 2-5)
● use lug bolts or equal to bolt down unit, reducing vibration
and noise.
● If cooling operation is to be used when the outdoor air
temperature is –5°C or below, install a duct on the outdoor
unit.
