For to prevent flicker impressions during the start of the compressor (technical process)following installation
conditions do apply.
1 ASH-28AT will be connected only to a supply with the relevant system impedance no
more than Zmax=0.267
2The power connection for the air conditioner has to be done at the main power distribution. This distribution has to
be of an low impedance. Normally the required impedance is eached at a 32A fusing point.
3 No other equipment has to be connected to this power line.
4For detailed installation acceptance please refer to your contract with the power supplier, if restrictions do apply
far products like washing machines air conditioners or electrical ovens.
5For power details of the air conditioner refer to the rating plate of the product.
6For any question contact your local seller.
7 This product must not be disposed together with the domestic waste.
This product has to be disposed at an authorized place for recycling
of electrical and electronic appliances.
8 The fuse indoor: T5AL, AC250V, outdoor: T3.15AL, AC250V.

Working voltage:50Hz 230V
Installation precaution:
To prevent possible hazards due to insulation failure,the unit must be grounded.
Provide a power outlet to be used exclusively for each unit,and a power supply disconnect and circuit breaker and
current fuse protector should be provide in the exclusive line.
Each wiring connection must be done in accordance with the wiring system diagram.Wrong wiring may cause the unit
to misoperate or become damage.
Please cut off power supply when unit will not be used for a long time.
Functions
Dehumidifying in rainy or humid season
Without reducing room temp.,air conditioner can
dehumidify and make room air dry and comfortable.
Heating in winter (heat pump type)
In cold winter,air conditioner can supply warm air to
rise room temp.

Cooling in summer
In hot summer,air conditioner can cool room air by
transfering heat out.
Operating automatically
According to room temp. change,microcomputer can
automaticlly set COOL or HEAT or FAN operation mode,
so as for best effect.
Working temperature range

Operation mechanism
Cooling cycle
Connected with pipes,indoor unit and outdoor unit form a refrigeration system.With power,compressor takes in
low temp.and low pressure refrigerant vapour from evaporator of indoor unit,presses it into high temp.and high
pressure gas,then discharges it into condenser of outdoor unit.By help of axialflow fan,heat is removed to outdoor
air from the gas which then condenses into liquid.After capillary tube throtting,the liquid drops temp.and pressure,
flows into evaporator.There,by help of cross-flow fan,the liquid absorbs heat from room air,evaporates and
becomes low pressure vapour which then flows into compressor again,beginning next cooling cycle.Therefore,
heat is transfered from indoor to outdoor,and room gets cool.
Ventilation cycle
Ventilation cycle divides into indoor and outdoor two parts.With suction of cross-flow fan,room air flows through
filters,exchanges heat in evaporator,then returns to room.In this way,room air can be cool and dehumidified.At
the same time,pumped by axial-flow fan,outdoor air flows through condenser and exchanges heat.
Heating cycle
Heat pump type air conditioner uses a commutator (4-way electromagnetic valve) to change refrigerant flow
direction.When heating,refrigerant firstly enters indoor heat-exchanger,releasing heat and condensing.Then it
enters outdoor heat-exchanger,absorbing heat and evaporating.Because consumption power changes into heat
which is discharged in room,heating efficiency is very good.

All above should be changed without notice. There are latest and accurate specification
on the nameplate of your air conditioner.

Smell
Sometimes there is some smell out
of indoor unit,as does not mean any
machine failure,but because of
suction air mixed with smell of
furniture or smoking etc.
Important notices
Do not cut or pull strongly power
lines and connecting lines.
Close doors and windows
(better using contains)while
operating air conditioner,to
avoid cool or heat leakage
which affects air condition.
If room air is quite turbid,you
should open a door or
window a little for a
moment to get some outdoor
fresh air.
It is only specific technician who can operate the stop valve of outdoor unit,otherwise it is possible to make refrigerant leak
out and compressor breakdown.
Air Conditioner should be
operated with stable voltage
in range of 198-253V1Ph,
otherwise, compressor
would vibrate terribly to
damage refrigeration
system.
Do not insert any foreign
materials into the air inlet
or air outlet, it is very
dangerous.
Delay operation
To avoid action of overload protector
or other security devices,we design a
delay for 3 4 minutes before starting
cooling or heating or dehumidifying
cycle in following situations:
To start again immediatelly after
stopping;
To adjust operation mode.
Electric circuit
Must use special electric circuit,do
not use longer power lines,do not
share a same socket with other
electric appliances to avoid fire etc.
