For

adequate

control

of

microbial

contamination

and

scale

buildup

as

well

as

routine

maintenance,

each

of

the

above

procedures

must

be

performed

at

the

re—

quired

frequency.

To

prevent

bacterial

growth,

test

and

adjust

the

chlorine

level

daily.

Cleaning

should

always

be

followed

by

sanitizing;

field

studies

indicate

that

performing

one

procedure

without

the

other

may

actually

increase

bacteria

levels.

Without

routine

cleaning

and

sanitization,

excessive

biofilrn

may

form,

requiring

a

prolonged

decontamination

procedure.

The

descaling

procedure

reduces

hard

water

deposits

from

affecting

the

operating

efficiency

and

safety

of

the

unit.
