Setting And Adjustment; Selecting The Power Supply Of The Fans - Trane MERCURY EDAB 1105A Technical Manual

To shut down the unit carry out the following procedure:
WA R N I N G ! D u r i n g p ro l o n g e d b re a ks a
spontaneous migration of the refrigerant may
occur in the casing of the compressor, which
may cause foaming of the oil and consequent
damage because of the lack of lubrification. It is
recommended that the main switch is not turned
off during weekly breaks.
• on the first screen of the user terminal, press keys A5
or A7 until the SWITCH OFF UNIT screen appears;
• press the ENTER key to confirm;

SETTING AND ADJUSTMENT

Selecting the power supply of the fans

WARNING! Before establishing the electrical
connection, make sure that the power supply
is off. Also ensure that it is not possible to
reconnect the power during the operation.
WARNING! In the case of a unit with ducts, the
load loss from the exhaust duct must be less
than 100 Pa.
In the following table the voltage levels for each model
working in the standard version are given.

HOW TO ADJUST FAN SPEED
In the ED*B and EU*B units, the speed of the fan rotation can be
varied by using the ATR transformer (F1).
To obtain the required prevalence of the implant, it is possible
to vary the voltage by selecting one of the following levels:
Models 0511-0611
140V -160V -180V -190 - 200V -210V -220V -230V
Models 0721-1822
230V - 250V - 260V - 270V - 280V - 290V - 300V - 310V - 320V -
340V - 360V - 380V - 400V.
Models 2222 - 2242 - 2522 - 2542 - 2842 - 3342 : 150V - 180V
- 200V - 230V - 240V - 260V - 280V - 300V - 320V - 340V - 360V
- 380V - 400V.
In the following table the maximum pressure available (expressed in
Pa) for each voltage level of the transformer is indicated. The values
are given for the maximum air flow (expressed in m3/h).
