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

air flow through filter element is correct. Improper flow direc-

tion can minimize filter performance.

(See Table 2).

Install differential pressure gauge (optional) on filter housing

using instructions provided with gauge kit. Differential pres-

sure is used to monitor element life (except grade RD) and

indicates when an element change is required.

(See Table 6).

Locate compressed air and gas filters at the point of lowest

operating temperatures to ensure that water and oil vapor will

not condense downstream of the filter.

Filters should be installed close to the point of use to mini-

mize the risk of pipe scale, dirt, etc. recontaminating the

compressed air or gas. This is particularly important when

installing new filters on 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 tempera-

ture 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 below filter to allow for replacement of elements.

(See Table 3).

WARNINGS

INSTALLATION (PART 1 FILTER HOUSING)

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, i.e.,

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 COR-

ROSION 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.

Insert close nipple in threaded hole on bottom blind flange

and tighten securely. Screw manual drain valve on close

nipple and tighten.

(See Figure 2). When automatic draining

is required, a motorized ball valve or solenoid type is recom-

mended.

NOTE

Vessel models F101-500 thru

F101-2000 are equipped with a

single long flange bolt to permit

rotating of blind flange for access

to elements.
