Section A

: Installation, Start-up and Maintenance

Introduction

1.1 This manual is a valuable tool covering the circulator

you have purchased.

1.2 Do not proceed with installation or operation until you

have read and understand this manual.

1.3 Following is a step-by-step approach covering instal-

lation, start-up, operation and maintenance of the

circulator.

1.4 Familiarize yourself with and refer to the circulator

drawing (Section B). Item numbers referred to in this

manual can be found on this drawing. Order specific

drawings can be found in Appendix 1.

1.5 The circulator purchased includes only the kit options

shown on these drawings. Additional kits are available

as described in Section C.

Installation

2.1 Location

2.1.1 Circulator location and ambient temperature

extremes must be taken into account. All inter-

connecting piping/tubing must be thermally

protected to insure a continuous flow of barrier

fluid.

2.1.2 Shading the circulator from direct sunlight is

recommended.

2.1.3 Installation must take place during a time when

ambient temperatures are above freezing or

with all fluid lines protected from damage.

2.1.4 Follow notes listed on the circulator order

drawings, in Appendix 1, covering utility require-

ments and control component points.

2.2 Lifting/uncrating

2.2.1 Remove the crating carefully to avoid damag-

ing components.

2.2.2 The circulator must be lifted only from the bottom

or by the lifting lugs when provided. Lift carefully

to avoid damaging circulator components.

2.3 Foundation/placement

2.3.1 The foundation (customer steel base or con-

crete pad) for the circulator should be flat and

level, with anchor bolts set firmly in place.

A foundation weight of not less than 3 times

the weight of the circulator (when filled with

barrier fluid) is recommended as a minimum

for concrete foundations. Steel baseplates

shall have sufficient rigidity to prevent distort-

ing the circulator after bolt down.

2.3.2 The foundation must be free of all debris prior

to placement of the circulator.

2.3.3 The circulator reservoir is fabricated such that

the top is level. Gently lower the circulator

onto the foundation and check to see if the

level is maintained. If required, shim mounting

feet level before bolting the circulator down.

Mounting bolts should be torqued per manu-

facturer’s specifications.

2.4 Interconnecting piping/tubing

2.4.1 Definition: Interconnecting piping/tubing is all

fluid piping/tubing between the circulator and

the process equipment.

2.4.2 Piping/tubing should be installed to meet local

codes or other applicable standards.

2.4.3 The interconnecting piping/tubing system

should be sized and constructed to minimize

pressure losses and should not be less

than the corresponding pipe/tube size and

schedule as contained in the circulator (refer

to the piping and instrumentation diagram of

pipe size, schedule and material).

2.4.4 The interconnecting piping/tubing system,

both to and from the seal, should be construct-

ed of similar material as the circulator.

2.4.5 Piping/tubing must not be supported by the

circulator.

2.4.6 Before installing, the piping/tubing system

should be checked for freedom from contami-

nation. If not completely free of contaminants,

clean and flush the entire interconnecting

piping/tubing system before connecting the cir-

culator. Once you are sure the piping/tubing

system is free of contamination, drain the

flushing media and air blow dry.
