„ GENERAL REQUIREMENTS
The piping, fittings, air receiver tank, etc. must be certified safe for at least
the maximum working pressure of the unit. Use hard-welded or threaded
steel or copper pipes and cast iron fittings that are certified safe for the
unit's discharge pressure and temperature. DO NOT USE PVC PLASTIC. Use
pipe thread sealant on all threads, and make up joints tightly to prevent air
leaks.
„ DRIVE OPTIONS
• DIRECT DRIVE
A 1100 series flange is available to direct drive the GD 70. The following
guidelines should be followed:
• Compressor shaft and PTO shaft should be parallel within 2 degrees.
• Maximum compound drive angle must be no greater than 11 degrees.
• Install a "U" bolt hanger for safety in case of a driveshaft failure.
• HYDRUALIC DRIVE
If the unit is to be driven by hydraulic motor, the shafts must be aligned as
follows:
• Shaft offset of no more than 0.015".
• Shafts parallel within 1 degree.

„ COMPRESSOR LUBRICATION
CAUTION
Do not operate without lubricant or with inadequate lubricant.
Gardner Denver is not responsible for compressor failure caused
by inadequate lubrication.
„ SYNTHETIC COMPRESSOR LUBRICANT
We recommend AEON AC-SY compressor lubricant from start-up. See the
WARRANTY section for extended warranty information.
„ ALTERNATE LUBRICANTS
You may use AEON AC-HC or a comparable petroleum-based lubricant that
is premium quality, does not contain detergents, contains only anti-rust,
anti-oxidation, and anti-foam agents as additives, has a flashpoint of 440°F
(227°C) or higher, and has an auto-ignition point of 650°F (343°C) or higher.
See the petroleum lubricant viscosity table below. The table is intended
as a general guide only. Heavy duty operating conditions require heavier
viscosities. Refer specific operating conditions to Gardner Denver for
recommendations.
