Locate compressed air and gas filters at the points of lowest
operating temperatures to ensure that water and oil will not
condense downstream of the filter.
Filters should be installed close to the point of use to
minimize the risk of pipe scale, dirt, etc. recontaminating the
compressed air or gas. This is particularly important when
installing new filters in an existing installation which has not
had proper filtration.
Protect filters from reverse flow conditions. Do not install
filters downstream of quick opening valves.
Before installing filter, check ambient and operating tem-
perature and pressure conditions to verify that they are
within the specified ranges. (See Table 1). Also verify that
system flow rate corresponds to the rated capacity of the
filter. (See table 4). Operating filter at flows above rated
capacity will result in increased pressure drop. Do not use
reducers to match filter inlet size. The resulting restriction will
cause high pressure drop.
Install filter in vertical position. Provide required minimum
clearance above filter to allow for replacement of elements.
(See Table 3).
Install inlet and outlet shutoff valves to facilitate replacement
of elements. By-pass piping is recommended.
Check labels on filter housing, and connect piping so that air
flows through inlet and outlet ports as indicated. Make sure
that air flow through filter element is correct. Improper flow
direction can minimize filter performance. (See Table 2).
Install differential pressure gauge (optional) on filter housing
using instructions provided with gauge kit. Differential
pressure is used to monitor element life (except grade RD)
and indicates when an element change is required.
Insert 1" NPT close nipples into 1" NPT couplings in vessel
and tighten securely. Screw 1" NPT manual valves onto 1"
close nipples and tighten securely. (See Figure 1).

DO NOT REMOVE, REPAIR OR REPLACE ANY ITEM ON VESSEL WHILE IT IS UNDER PRESSURE.
DO NOT OPERATE IF THERE IS A LEAK IN VESSEL. TAKE VESSEL OUT OF SERVICE IMMEDIATELY AND NOTIFY YOUR
CERTIFYING AUTHORITY.
DO NOT OPERATE ABOVE MAXIMUM WORKING PRESSURE (MWP) AT MAXIMUM OPERATING TEMPERATURE (°F)
SHOWN ON ASME NAMEPLATE.
THIS ASME CODE VESSEL MUST BE PROTECTED BY A PRESSURE RELIEF VALVE. Refer to OSHA 1910.169 Par b, Sub
Par (3) and ASME Boiler and Pressure Vessel Code, Section VIII, Div 1 UG-125, Par (1). Also check government regulations,
state and local codes.
DO NOT WELD, GRIND OR SAND VESSEL. IT WILL NOT BE SAFE TO OPERATE.
DO NOT OPERATE VESSEL IF THERE HAS BEEN A FIRE. TAKE VESSEL OUT OF SERVICE IMMEDIATELY AND NOTIFY
YOUR CERTIFYING AUTHORITY.
ANY DAMAGE TO VESSEL CAN MAKE IT UNSAFE. INSPECT OUTSIDE AND INSIDE OF VESSEL REGULARLY FOR
CORROSION OR ANY DAMAGE (i.e., DENTS, GOUGES OR BULGES). IF DAMAGED OR CORRODED TAKE OUT OF
SERVICE IMMEDIATELY AND NOTIFY YOUR CERTIFYING AUTHORITY.
USE THE PROPER RULES FOR THE GAS BEING PROCESSED.
