Useful Tips - Toyotomi NTN-928R32 User Manual

Refrigerant leakage contributes to climate change. Refrigerant with lower
global warming potential (GWP) would contribute less to global warming than
a refrigerant with higher GWP if leaked to the atmosphere. This appliance
contains a refrigerant fluid with a GWP equal to [675]. This means that if 1 kg
of this refrigerant fluid would be leaked to the atmosphere the impact on global
warming would be [675] times higher than 1 kg of CO2 over a period of 100
years. Never try to interfere with the refrigerant circuit yourself or disassemble
the product yourself. These tasks should be carried only by licensed
authorized technician.
Ensure no following objects are under the indoor unit:
 Microwaves, ovens and other hot objects.
 Computers and other high electrostatic appliances.
 Sockets that plug frequently.
The joints between indoor and outdoor unit shall not be reused, unless after re-flaring the
pipe.
The specifications of the fuse are printed on the circuit board, such as: 3.15A/250V AC, etc.
If your air conditioner is not fitted with a supply cord and a plug, an anti-explosion all-pole
switch must be installed in the fixed wiring and the distance between contacts should be no
less than 2.5 mm.
If your air conditioner is permanently connected to the fixed wiring, an anti-explosion
residual current device (RCD) having rated residual operating current not exceeding 30 mA
should be installed in the fixed wiring.
Power supply circuit should have leakage protector and air switch of which the capacity
should be more than 1.5 times of the maximum current.

USEFUL TIPS

Conditions where the Air Conditioner might not run normally
Cooling
Heating

When temperature is too high, the air conditioner may activate the automatic protection device, so that the air
conditioner could be shut down.
When temperature is too low, heat exchanger of the air conditioner may freeze, leading to water dripping or another

malfunction.
In long-term cooling or dehumidification with a relative humidity of above 80% (doors and windows open), there might

be water condenses or dripping near the air outlet.
T1 and T3 refer to ISO 5151.

NOTES FOR HEATING
The fan of indoor unit will not start running immediately after the heating is started to avoid blowing out cold air.
