Introduction
The L75 is a variable-displacement, oil fog type lubricator. The
L75 is designed to atomize lubricant into the air stream directly
before point of use. The rate of lubrication is automatically
proportioned to air flow, eliminating re-adjustment. Follow these
instructions when installing, operating, or servicing the product.
Application Limits
These products are intended for use with compressed air in
industrial applications. For other applications, consult factory

Installation
All FRL components are individually tapped (NPT or BSPP) to
allow direct mounting to piping. Also, each component comes
equipped with the necessary screws and O-rings to enable
connection to other components of the same series without
the need for pipe nipples or special adaptors. Before installing,
blow out pipe line to remove scale and other foreign matter. This
unit has DRYSEAL pipe threads; use pipe compound or tape
sparingly to male threads only. Install units in pipe line so that
flow is in direction indicated by arrows on faces of body. Install
as near as possible to equipment serviced.
Lubricant
For average conditions, the use of high quality SAE #10 (S.U.V.
150-200 SEC @ 100°F) oil is recommended. Other lubricants, as
specified by the maker of the equipment to be lubricated, may be
used if not heavier than SAE #40 (S.U.V. 800 SEC @100°F).

CAUTION
Polyurethane bowls, sight glass and sight domes on these units may be
attacked by certain chemicals. Never use solvents like carbon tetrachloride,
trichlorethylene, acetone, or paint thinner to clean any parts. These elements
can cause crazing or failure of the plastic parts. The polyurethane resin parts
are compatible with most hydrocarbon based synthetic lubricants but, before
using, check with the manufacturer of the lubricant or oil for compatibility
with polyurethane resin.
TO CLEAN POLYURETHANE BOWLS USE MILD SOAP AND WATER
ONLY!
