4. Installation for the first time
Air and moisture in the refrigerant system have undesirable effects as below:
● Pressure in the system rises.
● Operating current rises.
● Cooling or heating efficiency drops.
● Moisture in the refrigerant circuit may freeze and block capillary tubing.
● Water may lead to corrosion of parts in the refrigerant system.
Therefore, the indoor units and the pipes between indoor and outdoor units must be leak tested and
evacuated to remove gas and moisture from the system.
Gas leak check (Soap water method):
Apply soap water or a liquid neutral detergent on the indoor unit connections or outdoor unit
connections by a soft brush to check for leakage of the connecting points of the piping. If bubbles come out,
the pipes have leakage.
4.1. Air purging with vacuum pump
1) Completely tighten the flare nuts of the indoor and outdoor units, confirm that both the 2-way and 3-way
valves are set to the closed position.
2) Connect the charge hose with the push pin of handle lo to the 3-way valves gas service port..
3) Connect the charge hose of handle hi connection to the vacuum pump.
4) Fully open the handle Lo of the manifold valve.
5) Operate the vacuum pump to evacuate.
6) Make evacuation for 30 minutes and check whether the compound meter indicates -0.1Mpa. If
the meter does not indicate -0.1Mpa after pumping 30 minutes, it should be pumped 20 minutes more. If the
pressure can’t achieve -0.1Mpa after pumping 50 minutes, please check if there are some leakage points.
Fully close the handle Lo valve of the manifold valve and stop the operation of the vacuum pump. Confirm
that the gauge needle does not move (approximately 5 minutes after turning off the vacuum pump).
7) Turn the flare nut of the 3-way valves about 45° counterclockwise for 6 or 7seconds after the gas

controller, the buzzer will emit a sound and this indicates the follow me function is initiated. But when the
indoor PCB receives signal which sent from remote controller every 3 minutes, the buzzer will not
respond. When the unit is running with follow-me function, the PCB will control the unit according to the
temperature from follow-me signal, and the temperature collection function of room temperature sensor
will be shielded.
2) When the follow-me function is available, the PCB will not respond according to the setting temperature
from follow-me signal every 3 minutes.
Page 91
Electrical Control Function
90 Electrical Control System
3) The PCB will take action to the mode change information from remote controller signal, and the
follow-me function will be turned off. (if the wired remote controller does not initiate follow me function).
4) When the unit is running with follow-me function, if the PCB doesn’t receive any signal from remote
controller for 7 minutes or pressing FOLLOW ME button again, the follow-me function will be turned off
automatically, and the temperature collection function of room temperature sensor will be available, the
PCB will control the unit according to the room temperature detected from its own room temperature
sensor and setting temperature.
5) When the indoor PCB receives the follow-me signal from wired remote controller, the control is the
same as that from wireless remote controller, but buzzer will not respond. When the PCB receives
turning-off follow-me signal from wired remote controller, the unit will quit follow-me function at once.
The follow-me function controlled by wired remote controller prevails that by wireless remote controller.
1.3.13 8℃ Heating(optional)
