Notes Nominal cooling capacities are based on: indoor temperature: 27°CDB/19°CWB, outdoor temperature:
35°CDB, equivalent refrigerant piping: 7.5m, level difference: 0m
Nominal heating capacities are based on: indoor temperature: 20°CDB, outdoor temperature: 7°CDB/
6°CWB, equivalent refrigerant piping: 7.5m, level difference: 0m
Sound pressure level is a relative value, depending on the distance and acoustic environment. For more
details, please refer to the sound level drawings
Sound values are measured in a semi-anechoic room.

Notes RLA is based on following conditions: indoor temperature: 27°CDB/19°CWB, outdoor temperature:
35°CDB
Voltage range: units are suitable for use on electrical systems where voltage supplied to unit terminal is
not below or above listed range limits
Maximum allowable voltage range variation between phases is 2%.
Select wire size based on the value of MCA
Instead of fuse, use circuit breaker. MFA is used to select circuit breaker and the ground fault circuit
interrupter (earth leakage circuit breaker).
MSC means the maximum current during start up of the compressor
EN/IEC 61000-3-12: European/international technical standard setting the limits for harmonic currents
produced by equipment connected to public low-voltage system with input current > 16A and <= 75A per
phase
SSC means short-circuit power

4 Integrated heating capacity coefficient
3TW30402-1
Integrated heating capacity coefficient
The heating capacity tables do not take account of the reduction in capacity, when frost has accumulated or while the defrosting operation is in progress.
The capacity values, which take these factors into account, in other words, the integrated heating capacity values, can be calculated as follows
Formula:
Integrated heating capacity = A
Value given in table of capacity characteristics = B
Integrating correction factor for frost accumulation (kW) = C
A=BxC
Correction factor for finding integrated heating capacity
ERQ-AV1
Inlet port temperature of heat exchanger (°C/RH 85%) -7 -5 -3 0 3 5 7
Integrating correction factor for frost accumulation 0,88 0,86 0,8 0,75 0,76 0,82 1,0
Please note that, when there is an accumulation of snow against the outside surface of the outdoor unit heat
exchanger, there will always be a temporary redusion in capacity, although this will of course vary in degree in
accordance with a number of other factors, such as the outdoor temperature (°CDB), relative humidity (RH) and
the amount of frosting which occurs.
Note:
1. The figure shows that the integrated heating capacity
expresses the integrated capacity for a single cycle (from
defrost operation to defrost operation) in terms of time.
