Forced Ventilation
Forced ventilation is required for compressors with a 20 hp motor or greater. To determine the required
intake opening and exhaust flow refer to the following table:

Electrical Installation
4.2.2.3.1
Electric Drive
When making the electrical connections to the system, the following instructions are mandatory:
• Comply with all local, state and federal regulations concerning electrical installation.
• Arrange for the electrical connections to be made by a certified electrician only.
• Ensure that the motor voltage, control unit voltage, and frequency conform with the main voltage and
frequency. Do not connect the compressor unit to a voltage other than the one specified on the name-
plate.
• Provide all necessary cables and main fuses and a master disconnect switch. The fusing of the
compressor must be carried out in compliance with local, state and national electrical regulations.
4.2.2.3.2
Electrical Supply
The machine is factory wired according to order. If the voltage is to be changed, consult the factory for
instructions and necessary parts.
For standard models the only customer wiring necessary is from the customer supplied disconnect
switch to the compressor unit’s electrical enclosures All wiring should be done by a licensed electrician
familiar with national, state and local electrical codes.

The intake sizes given in the above table are for a cooling air velocity of 1000 ft./min. BAUER recommends that the cooling air velocity be in the range of 600 ft./
min. to 2000 ft./min.
V = 1750 ft³ h = 8 ft
V = 3500 ft³ h = 10 ft
V = 7000 ft³ h = 13 ft
