1 Introduction
Condensing units manufactured by Copeland are equipped with fan(s).
Various fan models are and were used.
That is to say that today, it is possible to meet various fan(s) on the after-sales market.
2 General
information
Condensing units can be equipped with 1, 2 or 4 fans.
The complete fan consists of an external rotor motor with the fan blades permanently fixed to the rotor and the fan
guard. The grid has 4 feet to mount it on the condenser.
Fan motors are protected by a thermostatic switch. A single-pole bimetallic-element switch protects the motor
against damage from:
Motor overload
Over-voltage and under-voltage
Electrical and mechanical blockages
Inadequate cooling.
The fans protection is IP 54 and its insulation class is "F".
Most fans can be equipped with a speed controller connected to the condensing pressure.

Fans for Copeland Scroll and DWM Copeland semi-hermetic condensing units
The fan is positioned in order to blow the air from the condenser to the compressor, so the compressor additional
fan is not necessary any more.
NOTE
: After connecting the condensing unit electrically, check the rotational direction.
The fan must blow from
the condenser to the compressor.
NOTE
: All fans presently used on condensing units are
single-phase
fans.
3.1 Single-phase
fans
Single-phase fans are used since January 2003.
