Operation And Performance - EAS Electric VRV EVR Series Instruction Manual

2.1 Short-circuit ratio statement
This equipment complies with IEC 61000-3-12 provided that the short-
circuit power Ssc is greater than or equal to 6280232W or 6401472W
at the interface point between the user's supply and the public system.
It is the responsibility of the installer or user of the equipment to
ensure, by consultation with the distribution network operator if
necessary, that the equipment is connected only to a supply with a

Indicatior Lights.
The protection equipment may be activated in following conditions:
■ Cooling Operation
The air inlet or air outlet of outdoor unit is blocked.
Strong wind is Continuously blowing to the air outlet of the
outdoor unit.
Heating Operation
■
Too much dust and rubbish adhere to the dust filter in the indoor
unit
The air outlet of indoor unit is choked
When the protection equipment starts, please shut down the
manual power switch, and restart operation after problem is
solved.
3.2 About power cut
If power is cut during operation, stop all the operation
immediately.

flashes. And then 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.
3.3 Heating capacity
The heating operation is a heat-pump process that heat will be
absorbed from outdoor air and released in doors. Once the
outdoor temperature is decreased, heating capacity decreased
corredpindingly.

NOTE
Other heating equipment is suggested to be used together
when outdoor temperature is too low.
In some extreme cold upland that buy another inddoor unit
equipped electrical heater will obtain better performance.
(Refer to indoor unit owner's manual for details)
1. The motor in Indoor Unit will continue running for 20~30
seconds for to remove residual heat when the Indoor Unit
recoeiving OFF command during heating operation.
2. If the air conditioner malfunction occurs because of disturb,
pleasereconnect the air conditioner to power, then turn on it
again.
3.4 Five-minute protection feature
A protection feature prevents the air conditioner from
being activated for approximately 5 minutes when it
restarts immediately after operation.
3.5 Cooling and heating operation
The indoor unit of the intelligent inverter centralized air
conditioner can be controlled solely, but the indoor unit in the
same system can not run cooling and heating at the same
time.
When the Cooling and Heating operation confront with each
other, the Indoor Unit which are running on Cooling Mode
would stop and there will be Standby or No Priority displayed
in the Control Panel. Those Indoor Units which are running on
Heating Mode will run continuously.
If the Air Conditioner Administrator has set running mode,
then the air conditioner can not run on modes other than the
presetted.Standby or No Priority will be displayed in the
Control Panel.
3.6 Features of heating operation
Warm air will not be blown out 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 blows out warm air.
During operation, the fan motor in the outdoor unit may stop
running under high temperature.
During Fan Operation, if other Indoor Units are running on
Heating Mode, the fan may stop in order to prevent sending
heat wind.
3.7 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.
