Please pay attention to the following:
• Please check the equipment with your check list after receiving the unit.
• Please keep the unit horizontal and balanced before hanging up the unit.
• Please ensure proper equipment (e.g., fork lift, hoist, sling, etc.) is used when handling the unit.
• Please remove all packaging material after installation.
If there are any problems or the unit is damaged, please contact authorized dealer.
1. Indoor Unit Installation
Carefully plan the installation location with the following considerations:
• Easy distribution of air ducts.
• Space for connection of refrigerant pipes, wirings and water pipes.
• Ceiling/structure is strong enough to support the unit.
• For noise consideration, always install unit away from air conditioned area.
• Always allow sufcient space for servicing and maintenance as shown in the following diagram:
• Use the hanging rods to hang the unit through the holes provided. Strength of hanging rods must be
able to support the total weight of the unit.
• During operation of the unit, there will be plenty of condensate water that needs to be discharged. In order to
prevent overow of condensate water, the water must be drained through condensate water pipe.
Please ensure a gradient is maintained as shown in the following diagram.
Unit should be installed by qualied technicians. Installation should adhere to local code and regulations.
• To reduce noise transmission through hanging rod, it is recommended to install rubber dampers or isolators.
• Mufer can be used to reduce noise transmission through air duct if the unit needs to be installed near
air conditioned area.

Sakura Air-cooled Split Ducted Air Conditioner

Condensate drain pipe installation:
• For easy drainage of condensate water, drain pipe must be sloped
downward at least at a gradient of 1:100.
• The drain pipe must have a U-bend.
• Drain pipe that runs under the ceiling or within the air conditioned
space should be insulated to prevent condensation of water.
Choice of insulation material can be PE, PU or other appropriate
insulation material.
Air Ducting Installation
• There are two types of discharge air-duct, namely rectangular and round ducts.
• Rectangular ducts can be connected to the discharge of the indoor unit directly. Refer to the dimension
drawing of the unit to see the dimensions of the discharge.
• Flexible connection must be installed between air ducts and indoor unit to ensure quiet operation.
• A reducer is necessary to connect the round duct to the discharge of the unit.
• Design of supply and return air duct should strictly adhere to the maximum static pressure that can be
delivered by the unit to avoid unsatisfactory unit performance and overload of fan motors.
2. Outdoor Unit Installation
To ensure the unit operates at optimum performance level and to maintain long life-span of components, the
choice of location of unit and installation recommendations as listed below should be followed:
• The discharge air and intake air direction of outdoor unit should not be blocked to ensure there is no
short circuiting of hot air.
• If there is more than 1 unit being installed at the same location, make sure that the discharge of one unit
does not face the air intake of another.
• The location of installation should be well ventilated and avoid direct sunlight.
• Location of installation should be able to drain rain water or condensation water.
• Ensure the location of installation does not face strong wind and is free from dust.
• Do not connect duct to the outdoor fan discharge.
• Do not install the unit at location that is near corrosive materials or chemicals.
• Avoid installing the outdoor unit under the window.
• Ensure the discharge of air and noise generated during operation do not affect the surrounding neighbors.
Note:
A U-bend must be installed along the
drain pipe. The recommendation is as
following:
100mm<h<150mm and x>h/2

Installation Clearance
To provide sufcient service clearance and to ensure good air intake and discharge, please refer to the
recommendation as follows:
Refrigerant Piping
Long refrigerant piping will affect the performance of the unit and shorten the lifespan of compressor. In the
worst-case scenario, it will cause the compressor to break down. Special precaution needs to be taken to
make sure that the maximum length of the piping strictly adheres to the recommended maximum pipe
length and elevation in the following tables:

Vacuuming and Refrigerant Charging
Vacuuming is necessary to eliminate all moisture and air from the system.
Vacuuming
After the system piping is properly connected, vacuum the air conditioner system to at least 500 microns Hg.
Charging
Before charging, the vacuum must be held at 500 microns Hg for at least 15 minutes. After charging, operate
the unit for 15 minutes, ensuring that refrigerant charges is of correct quantity by monitoring running
current and suction and liquid line pressures. Suction and discharge pipe pressures should be in the region
of 75 psig and 275 psig. After ensuring the system is correctly charged, remove exible hose from charging
nipples and replace with caps.
Attention:
Outdoor unit is not factory pre-charged with refrigerant.

Servicing and Maintenance
Indoor Unit
• Air Filter
The lter must be cleaned regularly and the frequency of cleaning is to be determined by the degree of
pollution of the environment of application. When washing the lter, rst tap it gently to remove larger particle,
and then rinse the lter in detergent and warm water. The lter must be dried before it is used. The lter is
recommended to be installed before the air grille or the indoor coil.
• Motor
It is not necessary to lubricate the motor for servicing and maintenance.
• Heat Exchanger
After in use for a while, the surface of the coil may collect dust, dirt or other undesirable substances. It is
recommended to clean the aluminum ns of the coil using a nylon brush or vacuum cleaner. If compressed
air is available, it can be used to clean the coil by direct blowing.
However, care must be taken not to damage the ns.
• Drain Pipe
Check the drain pipe regularly to prevent blockages by alien substances.
Outdoor Unit
Under normal operating conditions, outdoor unit should be checked quarterly and the coil surface should
be washed. If the outdoor unit is installed at location which is oily, smoky and dusty, regular service should be
done by a technician to make sure that the heat exchanger is always in optimum condition.
Warning
Do not use oxygen, acetylene, poisonous gas or any other gas that will cause explosion under high
temperatures and pressure for leak checking. Instead, use nitrogen or R22 for air leakage test.
