IV Installation & Piping 

General:

 

 

a.

 

All

 

plumbing

 

must

 

be

 

in

 

accordance

 

with

 

the

 

requirements

 

of

 

the

 

authority

 

having

 

jurisdic on.

 

b.

 

Use

 

both

 

thread

 

tape

 

and

 

pipe

 

dope

 

on

 

all

 

mechanical

 

connec ons.

 

c.

 

Zone

 

valve

 

(if

 

used)

 

and

 

circulator

 

must

 

be

 

sized

 

to

 

provide

 

minimum

and

 

heat

 

exchanger.

 

See

 

the

 

tables

 

on

 

Fric on

 

Loss.

 

Point

 

of

 

emphasis:

 

using

 

a

 

zone

 

valve

 

without

 

a

 

full

 

bore

 

may

 

cause

 

high

 

pressure

 

drop

 

which

 

will

 

adversely

 

a

ect

 

performance.

 

Use

 

extreme

 

care

 

when

 

selec ng

 

zone

 

valve.

 

d.

 

All

 

piping

 

must

 

be

 

adequately

 

supported.

 

e.

 

Allow

 

for

 

thermal

 

expansion.

 

f.

 

Dielectric

 

Unions

 

(recommended)

 ‐

used

 

to

 

electrically

 

isolate

 

the

 

Techtanium

 

tank

 

from

 

the
