1. GENERAL
The DS air-conditioners include two separate units - Indoor and Outdoor Unit. The two units are
interconnected by two refrigerant tubes and an electric cable. The DS indoor units can be supplied with right
or left hand access for service and tube connection. Right/left hand sides are defined when looking at the unit
from behind it (filter side). Unit functions are controlled by a Display Control Unit and a wireless Remote
Control (or optional wired Remote Control). For outline dimensions -see Figure 1.
WARNING
The air conditioner must be installed by authorized technicians, according to company specifications and
using company standard tubing, electric cables and proper installation tools. Failure to comply with the above
may invalidate your warranty!
2. UNIT LOCATION CRITERIA
In selecting proper location, the following criteria must be considered:
a) The outdoor unit and the indoor unit must be installed as close to each other as possible. For
tubing length and diameters - see Table No.1. If longer tubing is required consult your dealer.
b) Outdoor unit installation should provide for:
•Easy service access.
•Minimum disturbance to the owner and nearby neighbors.
•A minimum distance of 200 mm from the wall, as shown in Figure 6.
•If installed in a closed place (balcony, attic, etc.), outdoor air vent must be provided to prevent hot/cold
air from recirculating through the outdoor unit.
•If several outdoor units are installed in the same area, make sure that the hot air outlet from one
outdoor unit does not enter another outdoor unit.
•Verify that any wall on which the outdoor unit is installed is capable of carrying the unit’s weight. Do not
install on a light unstable structure susceptible to vibration.
•When installing on a balcony above the first floor, make sure that the outdoor unit location allows easy
access for removal of the top cover and/or the entire unit, if necessary
•If the outdoor unit is installed in a non-accessible location, long and flexible refrigerant tubing and
electrical cable must be installed to allow the unit to be moved for servicing.
•Do not install the unit in a highly polluted area in which the air is contaminated by oil mist, salt or
sulfuric gas.

4. INDOOR INSTALLATION
4.1 Indoor Unit Location (See Figure 3)
The indoor unit is designed for installation on a false ceiling or other compartment, where
there is no influence from outdoor conditions.
While selecting the location, the following conditions must be assured:
a) The location should assure free flow of the return air into the unit without
interference.
b) The unit should not be installed close to rooms where noise should be avoided
(bedrooms, children rooms, etc.).
The location should allow good air circulation.

Where the unit must be installed in an attic space or outside, the following conditions must be
assured:
a) The unit must be protected from rain, heat and radiation by an additional layer of 1”
thick thermal insulation.
b) The return-air duct should be as short as possible, with a minimum dimension of
700x300 mm (or similar cross section) with full acoustical lining inside, and no more
than two long-radius elbows. The cross section at the duct connection to the unit shall
be equal to that of the unit.
c) The distance between the return air grille and the air intake on the unit must be as
short as possible. A minimum free passage of 0.3 m is necessary along the entire
return-air path.
d) The installation should be designed to withstand the weight of the unit and avoid
resonance vibrations. Use serrated rubber mounting under the unit and flexible joints
for the air duct.
Design and prepare in advance easy access for servicing as follows: (See Figure 3)
e) The minimum height clearance for the installation is 470 mm.
f) Allow the access to the electrical control box to facilitate its easy removal by opening
the cover (fastened by 3 screws). Allow also the access to the 700 mm long cable
which is tied inside the unit to enable relocation of the control box.
g) A distance of 200 mm must be kept between the rear side of the unit and any near-by
wall, to allow free air passage.
h) A distance of 300 mm must be kept to allow free air intake and convenient access to
air filters. Allow the access to service panels from opposite sides (right and left) for
the maintenance of fan and motor.

4.2 Floor Mounting - for DS Series Only
(See Figure 4)
Place two layers of serrated 60x60 mm rubber pa at the four
corners under the unit base. Insert a 1.5 mm thick sheet metal
between the two rubber pads and between the bottom pad and
the concrete surface.

4.3 Ceiling Mounting
The indoor unit can be mounted using spring or serrated rubber
isolators.
a. Spring isolators mounting
Insert four 3/8” stu in the ceiling according to the
dimensions of the spring-type isolators. Mount four spring
type isolators as shown in Figure 5. Attach indoor unit to
the spring-type isolators and level it, using the leveling
nuts. Secure in place by tightening the fastening nuts.

b. Serrated Rubber Mounting
In sites where the spring isolators assemblies
cannot be installed, mount the unit as show in
Figure 6. Insert four 3/8” studs in the ceiling
according to the dimensions of the suspension
angle frame mounted on the unit. Prepare two
30x30 mm, 1.5 mm thick galvanized sheet metal for
each stud and assemble according to Figure 6. The
rubber pa may be substituted by springs suitable for
this type of installation.

5. OUTDOOR UNIT INSTALLATION
Installation on flat surface (roof, ground, etc.)
Install outdoor unit support in a position elevated at least
100 mm on a concrete pad, concrete block or wooden beams,
in order to allow free water flow underneath (See Figure 7).
