Operation and Performance

*Heating Performance

*Microcomputer-controlled Automatic Defrosting

Heat-pump air conditioners heat your entire room by recirculating air throughout the room, with the result that some time may be required after first starting the air conditioner until the room is heated.

This air conditioner operates on the heat-pump principle, absorbing heat from outdoor air and transferring that heat indoors. As a result, the operating performance is reduced as outdoor air temperature drops. If you feel that insufficient heating perfomance is being produced, we recommend you use this air conditioner in conjunction with another kind of heating appliance.

Instructions relating to heating (*) are applicable to HSFL 411, 531 XMR Indoor Units.

When using the Heating mode under conditions of low outdoor air temperature high humidity, frost may form on the outdoor unit, resulting in reduced operating performance.

In order to prevent this kind of reduced performance, this unit is equipped with a Microcomputer-controlled Automatic Defrosting function. If frost forms, the air conditioner will temporarily stop, and the defrosting circuit will operate briefly (for about 7 to 15 minutes).

1. Electric wiring Note:

The air conditioner must use special circuit , and wiring by the qualified electrician according to the wiring rules specified in national standard. The grounding wire and the neutral wire shall be strictly separated. Connect the neutral wire with grounding wire is incorrect. The electric leakage breaker must be installed. All the electric wire must be copper wire.When wiring,there shall keep a proper distance between the power line and communication wire to avoid twist together. Otherwise,signal disturbance will occur,and the air conditioner can not operate normally. Power supply: 1PH, 220-230V~, 50Hz. The wiring method of power line is Y connection. If the power line is damaged, in order to avoid risk of electric shock, it must be replaced by the manufacturer or its repair center or other similar qualified person.The connecting cable must be shielded. Fuse: T3.15A 250VAC T25A 250VAC (Please check with the outdoor unit wiring diagram.) Please check the circuit diagram about the fuse replaced.

3.5 Electric heater (crankcase) control

If compressor has not run for a long time, the refrigerant will deposit on the bottom of compressor and mix with the refrigerant oil. When re-startup, because low pressure reduces, refrigerant will be segregated

from the refrigerant oil and cause soam in the oil, which will make compressor exhaust a lot of oil.

Therefore please stop heating the compressor bottom to ensure the low pressure in startup period should

not go down greatly.

 Ambient temp. TA≤27degree, when compressor stops, the electric heater will be electrified.  When TA≥32degree, or compressor running, the electric heater will be off.

3.10 High pressure protection When the input signal of pressure switch is high level: 1, that shows there is no protection.

When the input signal of pressure switch is low level: 0 for 1 minute, that shows high pressure protection

works. At this time, compressor stops, outdoor will send the alarm signal. The alarm can be resumable. If

in 60 minutes, the failure occurs 3 times, the failure can be confirmed and send failure code to indoor.

Meanwhile, by controling the max. condensate temp. Tc (cooling) or TmAVE (heating), please confirm as

follow:

In nominal cooling/dry/heating mode, high pressure can be controlled by limiting the max. frequency.

3.11 Low pressure protection

(1) When compressor is running, if output signal of low pressure switch is low level: 0 for 1 minute

continously, compressor will stop, outdoor alarms. The alarm can be resumable. If in 60 minutes, the

failure occurs 3 times, the failure can be confirmed and send failure code to indoor.

(2) When compressor no running, if output signal of low pressure switch is low level: 0 for 30 seconds

continously, alarm will occur.

·When unit stops, the reason that system still checks the low pressure: in a long time stop, make

protection for the compressor on the condition of great refrigerant leakage.

·The reason that low pressure switch action time is 30 seconds: when compressor stops, low pressure

does not change, so it will be shorter than the set time in operation.

(3) When compressor starts up, in 8 minutes, low pressure switch signal will be shielded.

(4) In defrosting, low pressure switch will be shielded.

(5) In oil return procedure, low pressure switch will be shielded.

(6) In the refrigerant discharging procedure after the oil return in cooling is over, low pressure switch will

be shielded.

In addition, the system will control low pressure through the evaporator temp. TE to realize the low

pressure protection function.

Keep for 5 seconds, stop to alarm, after 3-minute standby, the unit can re-startup. In 3 minutes it occurs 3 times continously,

unit will stop to alarm and the failure can be resumed after being

electrified again.

Press ON/OFF button (from OFF mode to ON mode), the times of SLEEP button to be pressed is the set

unit number, then press ON/OFF button to quit unit number setting state, at this time, indoor unit is at OFF

state, the display panel will display this unit number. For example, press SLEEP button once, it is No. 1

unit; press twice, it is No. 2 unit, and so on.

3) Quit method

In OFF state, press emergency switch until 15 seconds later, the buzzer sounds 5 times, the display

panel will display this unit number and you can check if there are repeated numbers.

21. Setting method of temperature compensation Tcomp

A. On wired control type unit YR-E12, this function is not available.

B. Remote control type unit:

In cooling or heating mode, there is always with the temp. compensation. In heating mode: In 24°C heating mode, press SLEEP (or SWING) button 7 times continuously within 5

seconds, indoor buzzer sounds twice, that shows temp. compensation works. Switch on the unit in

heating mode by the remote controller, press TEMP button to set the set temp., so temperature compensation=the current set temp. - 24°C. For example, if the set temp. is 24°C, the temp. compensation is 0°C; if the set temp. is 25°C, the temp. compensation is 1°C. The max. compensation temp. is 6°C (the set temp. is 30°C). If you want to cancel it, set the temp. as 24°C. In cooling mode: In 24°C cooling mode, press SLEEP (or SWING) button 7 times continuously within 5

seconds, indoor buzzer sounds twice, that shows temp. compensation works. Switch on the unit in

heating mode by the remote controller, press TEMP button to set the set temp., so temperature compensation=24°C - the current set temperature . For example, if the set temperature is 24°C, the temp. compensation is 0°C; if the set temp. is 23°C, the temp. compensation is -1°C. The max. compensation temp. is -8°C (the set temp. is 16°C). If you want to cancel it, set the temp. as 24°C. So the temp. compensation range is +8°C - 6°C.

22. Anti-freezed protection

When compressor has run for over 5 minutes, to prevent indoor evaporator freezing (in cooling/dry mode),

if indoor mid-coil temp. is below -1 degree for over 5 minutes, indoor EEV will close, and compressor will stop. When indoor mid-coil temp. is over about 10 degrees, the unit will be normal.

23. Overload protection in heating mode

It is valid only in heating mode, if indoor mid-coil temp. is over about 65 degrees continuously for 10 seconds, indoor will stop; while when indoor mid-coil temp. is below 52 degrees for 3 seconds, indoor will

resume.

Followings are not problems

Sound of water flowing is not a problem.

Sound of cracking is heard.

Smell are generated.

During operation, white fog or steam comes out from the indoor unit.

No outlet air or fan speed can't be changed in dry mode.

In cooling operation, unit switches to blowing operation.

Won't start?

In heating operation, water or steam are blown out of outdoor unit.

In heating operation, indoor fan won't stop even if unit is stopped.

During unit operation or at stop, a swishing or gurgling noise may be heard. This noise is generated by refrigerant flowing in the system.

Unit will not restart after stop.

During unit operation, a cracking noise may be heard. This noise is generated by the casing expanding or shrinking because of temperature changes.

This is because the system circulates smells from the interior air such as the smell of cigarettes or the painting on the furniture.

When unit is running at places like restaurant, etc. where dense edible oil fumes always exist, this will happen.

To prevent frost from accumulating on indoor heat exchanger, unit will switch to blowing operation for a while then resume cooling operation.

Though ON/OFF button is set to ON, unit won't resume cooling, dry or heating operation in 3 min after it is stopped, this is because of 3-min-delay protection circuit.

Please wait 3 minutes

Unit will reduce fan speed repeatedly and automatically if room temp. is too low in dry operation.

This occurs when frost accumulated on the outdoor unit is removed. (during defrosting operation)

After unit stop, indoor fan will go on running until indoor unit cools down.

Apparent abnormalities

-82-

Before ask for services, please first check your unit against the following.

Air conditioner won't start.

Poor cooling or heating

Is power supply switch turned on?

Power supply switch is not set at ON.

Is city power supply normal? Is leakage current breaker

activated?

This is very dangerous, please disconnect power supply immediately and contact your dealer.

Are operation control adjusted correctly as specified?

Is air filter too dirty?

Are there any obstacles in inlet or outlet grill?

Are horizontal louvers at up position (in heating mode)?

Any doors or windows left open?

Is there any direct sunlight in the room?

If there are unexpected heat sources in the room?

Too many people in the room?

Poor cooling

Is air conditioner in standby condition in heating mode?

Cold air blows out (in heating mode)

If your unit still can't work properly after above mentioned checks, or following problems occur, please stop it immediately and contact your dealer. Fuses or circuit breakers often blow out. W ater comes out in cooling/dry operation. Operation is abnormal or sound is heard.

CAUTION

Before cleaning the air conditioner ,be sure to turn it off and disconnect the Power Supply Cord. Be sure the Intake Grill is installed securely. When removing and replacing the air filters, be sure not to touch the heat exchanger, as personal injury may result.

Cleaning the Air Filter

Open the Intake Grill

1. Pull out both sides and the center of the Intake Grill.

2. Pull the Air Filters upward to remove them.

3. Clean the Air Filters.

5. Push in both sides and the center of the Intake Grill.

4. Re-attach the Air Filters to the Intake Grill.

Push the Air Filter handles away from the Intake Grille in direction as illustrated, then pull out Air Filters.

Remove the dust from the Air Filters by vacuum cleaner or washing them. After washing, allow the Air Filters to dry thoroughly in an area protected from sunlight.

The Filters fit onto the inside of the intake Grill. (figure 1) The bottom edges of the Air Filters should fit into the filter brackets. (figure 1) The Air Filters should be pushed down so that their top edges fit under the projections at the top of the Intake Grill. (figure 2)

Dust can be cleaned from the Air Filter either with a vacuum cleaner, or by washing the filter in a solution of mild detergent and warm water. If you wash the filter, be sure to allow it to dry thoroughly in a shady place before reinstalling. If dirt is allowed to accumulate on the Air Filter, air flow will be reduced, lowering operating efficiency and increasing noise. During periods of normal use, the Air Filters should be cleaned every two weeks.
