NOTE

24

Never expose little children, plants or animals directly to 

the air flow. 

Adverse influence to little children, animals and plants may 

result.

Do not allow a child to mount on the outdoor unit or 

avoid placing any object on it.

Falling or tumbling may result in injury.

Do not operate the heat pump when using a room 

fumigation - type insecticide. 

Failure to observe could cause the chemicals to become 

deposited in the unit, which could endanger the health of 

those who are hypersensitive to chemicals.

Do not place appliances which produce open fire in 

places exposed to the air flow from the unit or under the 

indoor unit.

It may cause incomplete combuston or deformation of the unit 

due to the heat.

Do not install the heat pump at any place where 

flammable gas may leak out. 

If the gas leaks out and stays around the heat pump, a fire 

may break out. 

The appliance is not intended for use by young children 

or infirm persons without supervision.

Young children should be supervised to ensure that they 

do not play with the appliance

.

The outdoor unit window-shades should be periodic 

cleaning in case of being jammed.

This window-shapes is heat dissipation outlet of components, 

if being jammed will cause the components shorten their 

service life spans because of overheated for a long time.

The temperature of refrigerant circuit will be high, please 

keep the interconnection cable away from the copper 

tube.

13  OPERATION AND PERFORMANCE

13.1 Protection Equipment

The protection equipment may be activated in following conditions:

The air inlet or air outlet of outdoor unit is blocked.

● Strong wind is Continuously blowing to the air outlet of the

outdoor unit.

Too much  rubbish adhere to the  filter in the water system

The air outlet of indoor unit is choked

Cooling Operation

Heating Operation

This Protection Equipment will enable the Heat Pump  to stop

when the Heat Pump is to be directed running compulsively.

When the protection equipment starts, please shut down the 

manual power switch, and restart operation after problem is

solved.

13.2 About power cut

   If power is cut during operation, stop all the operation immediately

.

Power comes again. If the auto-restant function is set on,then the unit 

  will auto-restart.

● Mishandling in operation:

If mishandling happens because of lighting or mobile wireless,

please shut off the manual power switch, and turn on again, then

push the ON/OFF button.

13.3 Heating capacity

The heating operation is a heat-pump process that heat will be 

absorbed from outdoor air and released to indoor water. Once

the outdoor temperature is decreased, heating capacity 

decreased corredpindingly.
Other heating equipment is suggested to be used together when 

outdoor temperature is too low.
In some extreme cold upland that buy the indoor unit equipped

with electrical heater will obtain better performance.( Refer  to 

indoor unit owner’s manual for details)

If the heat pump malfunction occurs because of disturb, 

please reconnect the heat pump to power, then turn on it 

again.

1.

2.

A protection feature prevents the heat pump from being 

activated for approximately several minuites when it restarts 

immediately after operation.

The  the indoor unit in the same system can not run cooling 

and heating at the same time.

13.6 Features of heating operation

Water will not become hot immediately at the beginning of 

the heating operation, 3~5 minutes ago (depends on the indoor 

and outdoor temperature), until the indoor heat exchanger 

become hot, then becomes hot.

During operation, the fan motor in the outdoor unit may stop 

running under high temperature.

13.7 Defrost in the heating operation

During heating operation, outdoor unit sometimes will frost. To 

increase efficiency, the unit will start defrosting automatically 

(about 2~10 minutes), and then water will be drained out from

outdoor unit.

During defrosting,  the fan motors in the outdoor unit  will 

stop running.

If  the Heat Pump Administrator has set running mode, then 

the heat pump  can not run on modes other than the presetted.

Standby or No Priority will be displayed in the Control Panel.

13.4 Compressor protection feature

13.5 Cooling and heating operation

The motor in outdoor Unit will continue running for 60 

seconds for to remove residual heat when the outdoor 

Unit recoeiving OFF command during heating operation.
