Extra

 

attention

 

must

 

be

 

made

 

to

 

filters

 

in

 

pool

 

environments

 

due

 

to

 

high

 

levels

 

of

 

moisture

 

and

 

chlorine.

  

Increased

 

replacement

 

frequency

 

is

 

often

 

required

 

and

 

can

 

only

 

be

 

determined

 

on

 

an

 

individual

 

basis.

  

Check

 

filters

 

weekly

 

to

 

establish

 

a

 

replacement

 

schedule.

 

 

Warning:

 

Failure

 

to

 

maintain

 

filter

 

quality

 

may

 

cause

 

building

 

damage,

 

injury

 

or

 

death,

 

poor

 

air

 

quality

 

or

 

other

 

problems.

 

 

 

Units

 

that

 

operate

 

with

 

high

 

levels

 

of

 

outside

 

air

 

should

 

have

 

filters

 

removed

 

(or

 

moved

 

to

 

winter

 

filter

 

location

 

if

 

available)

 

during

 

the

 

winter

 

months

 

in

 

areas

 

that

 

have

 

heavy

 

frost

 

or

 

snow.

  

 

Plugged

 

or

 

excessively

 

dirty

 

filters

 

can

 

cause

 

damage

 

to

 

the

 

equipment.

 

See

 

submittal

 

record

 

for

 

filter

 

quantities,

 

sizes

 

and

 

types.

 

Use

 

same

 

size

 

and

 

type

 

for

 

replacement.

 

 

High

 

Velocity

 

Permanent:

 

 

It

 

is

 

important

 

that

 

the

 

filters

 

be

 

checked

 

and

 

cleaned

 

regularly

 

during

 

the

 

period

 

immediately

 

following

 

installation,

 

in

 

order

 

to

 

determine

 

the

 

best

 

service

 

interval.

 

To

 

clean,

 

rinse

 

with

 

water.

 

Shake

 

off

 

excess

 

water

 

and

 

re

install.

 

These

 

filters

 

do

 

not

 

require

 

an

 

oil

 

adhesive.

  

 

Pleated

 

Throwaway

 

and/or

 

Replaceable

 

Media

 

(Cartridge,

 

Bag):

 

 

Replacement

 

filters

 

can

 

be

 

obtained

 

from

 

any

 

Engineered

 

Air

 

representative.

  

 

In

 

some

 

applications

 

the

 

used

 

filters/media

 

may

 

contain

 

chemical

 

or

 

biological

 

hazards.

  

All

 

local,

 

regional

 

and

 

national

 

regulations

 

for

 

safety

 

and

 

disposal

 

should

 

always

 

be

 

followed.

 

CONTROLS

 

 

Annually

 

clean

 

and

 

recalibrate

 

all

 

controls,

 

check

 

for

 

proper

 

operation,

 

and

 

repair

 

or

 

replace

 

any

 

faulty

 

controls.

 

Check

 

all

 

damper

 

hardware

 

settings

 

every

 

three

 

months.

 

Replace

 

blown

 

fuses

 

with

 

equivalent

 

size

 

and

 

type

 

fuse.

 

Failure
