3. Features
3.1 Wide application
The Sinclair small outdoor unit is a highly efficient solution for small commercial buildings requiring heating
and cooling of up to 7 zones with one outdoor unit. Such as villa, restaurant, school etc.
Sinclair offers a variety indoor unit, more than 40 models of 7 types. Capacity ranges are from 2.2kW to 16
kW. It is full compliance with residential and light commercial place. Our systems can operate up to 130% of
capacity which allows any system to be designed to the customers and applications needs.

Features

Compressor
(Twin Rotary) structure
3.2 High efficient DC inverter compressor
Sinclair small outdoor units adopt highly intelligent inverter-driven compressor. This advanced technology enables the output of
the outdoor unit to be modulated by the real heat load demands. This advanced system ensures precise temperature
regulation and highly efficient energy usage, making a significant contribution to the limiting the impact on the
environment.
3.3 High performance heat exchanger
The new designed window fins enlarge the heat-exchanging area,
which decrease the air resistance, save more power and enhance heat
exchange performance.
Hydrophilic film fins and inner-threaded copper pipes optimize heat
exchange efficiency.
3.4 Low-operating sound design
Optimally design fan shape and new designed discharge air grille and air deflector, making higher air volume
and lower operation sound.
3.5 Quick warm-up & cool-down design and less temperature fluctuation
Utilizing the inverter compressor benefits,
the system can reach full load quickly and
shorten warm-up or cool-down time for an
immediate comfortable air solution.
Less temperature fluctuation will create a
better living environment. Used across entire range of models.
Efficiency improvement by up to 45% especially at low speed.

3.6 Wide operation temperature range
No matter in extremely cold winter when outdoor
temperature gets as low as -15°C or in hot summer
when temperature is up to 48°C, the small outdoor
unit will keep stable performance.
3.7 Flexible piping design
3.8 Flexible indoor unit’s connection
Small outdoor unit with intelligent control gives you independent zoning control with maximum flexibility. A
single outdoor unit supports up to nine indoor units, freeing up considerable space outside. Use your
backyard more wisely with much more space available created by less number of outdoor units.
 Max. 9 indoor units for a 18kW outdoor unit installation
3.9 Simple signal line connection
Installation is much easier as the communication wiring between indoor & outdoor units can be shared.
It’s easy for the user to retrofit the existing system with a centralized control by simply connecting to
outdoor units.
3.10 Auto address setting function
The addresses of indoor units can be set automatically by outdoor unit.
Wired controller and wireless controller can enquire and modify the address of each indoor unit.

Features

3.11 Easy piping connection
Offering four directions to connect pipes and wirings
to meet various installation requests.
3.12 Easy installation
The small outdoor unit can be transported by elevator
which makes installation dramatically easy, and effectively
reduces time and labor thanks to the small size.
3.13 Easy maintenance
Forced cooling button makes outdoor unit run in cooling mode at
any condition, so it is very easy for you to charge refrigerant to the
system when it needs to be done. The self-diagnosis function
detects malfunctions in major locations in the system and displays
the type of malfunction and location. This allows service and maintenance
to be performed more efficiently.
3.14 Space saving
The small outdoor units are more compact, resulting in significant savings in installation space. It is
particularly suitable for small offices, villas, shops, etc.

4. Notes
If ODU connect only one IDU, the capacity of IDU should be not more than ODU.
If ODU connect more than one IDU, the capacity of each IDU should be not more than 8kW for refrigerant uniform distribution.
Due to continuous improvement, specifications are subject to change without prior notice.

Notes:
1. The cooling conditions: indoor temp.: 27℃DB (80.6℉), 19℃WB (60℉) outdoor temp.: 35℃DB (95℉) equivalent pipe length:
5m drop length: 0m.
2. The heating conditions: indoor temp.: 20℃DB (68℉), 15℃WB (44.6℉) outdoor temp.: 7℃DB (42.8℉) equivalent pipe length:
5m drop length: 0m.
3. Sound level: Anechoic chamber conversion value, measured at a point 1 m in front of the unit at a height of *m(0.9m for
80model, 1m for 105 model,1.2m for 120~180 model). During actual operation, these values are normally somewhat higher as a
result of ambient conditions.
4. The aboved datas may be changed without notice for future improvement on quality and performance.
