F-4600 With LCD Flow Meter Manual 06/18 - 2020-3 / 35874 Page 7

1.4 WORKING ENVIRONMENT

The F-4600 with optional LCD display was designed for installation and use indoors or outdoors

in protected spaces, or in residential, commercial and light industrial environments that are free

of corrosive liquids and fumes, temperature extremes and excess vibration.

The operating ambient air temperature range is -13°F to 131°F. The electrical power should be

relatively clean, free of excess high frequency noise and large voltage transients.

1.5 SERIAL NUMBER

The serial number of your F-4600 is located on the side of the enclosure. The serial number

is a unique identier for the product. Please have this number available when contacting

ONICON for assistance.

F-4600 With LCD Flow Meter Manual 06/18 - 2020-3 / 35874 Page 8

SECTION 3.0: INSTALLATION

The F-4600 Flow Meter should be installed by experienced plumbers, electricians, and others with

related knowledge and experience in the heating, cooling, and uid metering elds. ONICON technical

support personnel are available via telephone or e-mail to provide technical assistance before, during

and after installation. On-site eld engineering, installation, and service are also available at an

additional cost. The installer should use good trade practices and must adhere to all state and local

building, or other, applicable codes.

Before you begin, clean the external surfaces of all pipes at the installation site so that it is free of

debris, foreign matter, solids, leak inhibitors, and chemically aggressive substances. Flush the entire

system so that it is free of ux, solder, pipe and tube cuttings and any other free moving debris.

3.1 SITE SELECTION

Careful attention to the site selection for the meter will help the installers with the initial

installation, reduce start-up problems, and make future maintenance easier. For example, do not

install the meter where it will be difcult for personnel to perform periodic maintenance. When

selecting a site, consider the criteria under Section 1.4: WORKING ENVIRONMENT, as well as

the information below.

The following limitations apply to the installation of the meter:

• The ow meter must be correctly oriented with respect to the direction of ow in the pipe.

Meters installed with reversed ow will not function.

• The F-4600 is provided with a 4.9 ft (1.5 m) cable for the detachable enclosure. Do not alter

this cable length. Doing so will void the calibration and may invalidate the warranty.

• The maximum operating pressure for the ow meter is 400 psi.

• At uid temperatures above 212°F, the enclosure should be remote mounted.

• Do not install the meter in close proximity to strong sources of electromagnetic interference

(e.g. electric motors, VFD’s, uorescent light xtures, etc.)

3.2 INSTALLING THE FLOW SENSOR

Before you install the meter, the entire piping system should be ushed and free of debris. Please

refer to the diagrams on the following page when selecting the installation location. Upstream

straight unobstructed pipe requirements vary considerably based on nature of the upstream

obstructions. As a general rule, ONICON recommends a minimum of 10 diameters of straight

unobstructed pipe whenever possible; keeping in mind that it is always recommended that the

meter be located with as much straight pipe upstream as possible. Recommended minimum

straight run requirements are provided on the following page.

11451 Belcher Road South, Largo, FL 33773 • USA • Tel +1 (727) 447-6140 • Fax +1 (727) 442-5699 • [email protected]

F-4600 With LCD Flow Meter Manual 06/18 - 2020-3 / 35874 Page 9

A. This is a recommended position for the ow sensor.

B. Avoid installation locations where air can become trapped in the piping system.

C. This is an acceptable installation location for closed loop pressurized systems.

D. Do not install the sensor downstream of modulating valves or partially open valves.

Fully open isolation valves (e.g. ball valves) are OK.

E. Do not install the ow sensor at the inlet of a pump. To prevent cavitation, the

minimum operating pressure at the inlet of the meter must always exceed the pressure

drop across the meter. Refer to Appendix A-3 for calculating pressure the drop at

different ow rates.

F. Avoid installing the meter downstream of multiple bends out of plane with each other

where there are less than 10 diameters of straight unobstructed pipe between bends.

INSTALLING METER COUPLINGS

• Inspect seating surfaces on the meter’s body and tail piece prior to assembly. Surfaces should be

clean and free of any burs or markings.

• Install the gasket in tail piece. Thread union onto meter’s body, by hand, until gasket and mating

surfaces make rst contact. Mark coupling nut and tail piece.

• Place a corresponding mark on the coupling nut, # of degrees (based on table above) counter

clockwise. Hold meter body while rotating coupling nut clockwise until marks line up. DO NOT

over-tighten.

• Repeat process on opposite side of ow meter body.

NOTE: Torque setting is not an accurate means of gaging compression on gasket due to the lack of

resilience in the gasket material.

• Pressurize system and check for leaks. If any leak is present, DO NOT over-tighten. Relieve pressure

and loosen coupling nuts. Remove and inspect the gasket for damage. Repeat installation process.
