1.4 Product features
Adopt the much friendlier refrigerant R410a
The air conditioner system adopts the greatly friendly refrigerant R410a, which is protective for the
ozone layer and is good to avoid the earth getting warmer. Benefit for the environment.
Universal outdoor unit
The outdoor unit has been uniformed which can be connected with different type indoor units with
identical capacity such as cassette type, duct type, convertible type etc..
High efficiency filter
Multi-mode for installation
Auto–restart function (optional)
All indoor units have auto-restart function. When the power supply cut off suddenly, the unit will
automatically recover the previous running mode once the power supply is on.
Group control function (with a group controller YR-E12)
Central control function, if connected with a central controller
YCZ-A001
Weekly timing function, if connected with a weekly timer YCS-A001
The unit adopts G3 grade filter, can efficiently filter the dirt etc, and improve the room air quality, at
the same time, the filter can pull out from downside, convenient for maintenance and cleaning.
The indoor unit can be installed with an air return duct or without an air return duct according to
the installation need.
PAM control
PAM adjusts the form of the current wave so that it becomes close to that of the supply voltage wave.
High harmonice are reduced and 99% of the electricity is utilized.

1.5 New friendly refrigerant R410A introduction:
■R410A
The working pressure of R410A is approximately 1.6 times higher than R22. Because the oil in the
refrigerant is different, please do not mix them.
Refrigerant R22 (single) R410A (mixed) R407C (mixed)
Oil Mineral oil (SONTEX 200LT) Synthetic oil (POE oil) Synthetic oil (POE oil)
Pressure ratio 1 Approx. 1.6 Approx. 1.1
■Operation flow
1. Calculate the refrigerant additional charging
amount, and charge a suitable amount.
1. Air purging by refrigerant is prohibited seriously
2. Use a special vacuum pump with reverse check
mechanism
1. Charge the nitrogen to the set pressure
2. 24 hours later,check if the pressure in the pipe
has reduced
1. Do not connect the power supply
1. Use piping material of the specified thickness
2. Do not use dirty pipe
3. Always flow nitrogen during welding work

■Piping material
1. Use the correct refrigerant piping and materials for R410A
2. For the pipe wall thickness, see the table below:
Pipe diameter Φ6.35 Φ9.52 Φ12.7 Φ15.88 Φ19.1
Pipe wall thickness 0.8 0.8 0.8 1.0 1.2
Note: Always observe and comply with the local regulations when installing the refrigerant piping.
■Tools
R410A work requires a number of special tools (* symbol). Since the tools used in R22 work
cannot be used for R410A, provide the tools separately.
Tool name Process and application
Pipe cutter Piping cutting
*Flaring tool Pipe flaring work
*Torque wrench Flare nut connection
Expander Expansion at pipe connection
Pipe bender Pipe bending work

■Work precautions
Refrigerant check: Before work, check the used refrigerant and prepare materials matched to the
refrigerant.
Refrigerant piping: Observe the basics of refrigerant piping to avoid the unnecessary problems. In
addition, when performing the welding work, seal in the nitrogen gas to the pipes, and prevent it
from the oxidation.
Leak pressure detection: Perform seal detection and make sure there is no refrigerant leakage.
Vacuum drying: If the vacuum pump has not the reverse flow check mechanism, use the pump
together with a reverse flow check adapter.
Additional refrigerant: Charge a suitable amount of refrigerant with a special R410A gauge
manifold and charging hose.

Air-conditioner can't be installed in
the environment with inflammable
gases because the inflammable gases
near to air-conditioner may cause fire
hazard.
Connect earthing wire.
Use discharge pipe correctly to ensure
efficient discharge.
Earthing wire should not be con-
nected to the gas pipe, water pipe,
lightning rod or phone line, in-correct
earthing may cause shock.
Incorrect pipe use may cause water
leaking.

Incorrect installation may cause water
leak, electrical shock and fire hazard.
Call the dealer to take measures to
prevent the refrigerant from leaking.
If conditioner is installed in a small
room be sure to take every measure in
order to prevent suffocation accident
even in case of refrigerant leakage.
When conditioner is removed or
reinstalled, dealer should be responsible
for them.
Incorrect installation may cause water
leaking, electrical shock and fire hazard.
Nothing or nobody is permitted to
placed on or stand on outdoor unit.
The falling of goods and people may
cause accidents.
Don't operate the air-conditioner with
damp hands.
Otherwise will be shocked.
Only use correctly-typed fuse.
May not use wire or any other materials
replacing fuse, other-wise may cause
faults or fire accidents.
