of

elements:

Caused

by

water

voids

when

power

is

on.

All

air

must

be

purged

from

system

before

any

heater

start-up.

It

is

especially

important

to

purge

all

air

after

cleaning

or

changing

a

cartridge

filter.

Since

the

filter

casement

acts

as

an

air

reservoir

during

this

procedure,

the

circulation

system

must

be

on

for

at

least

five

minutes

to

purge

and

bleed

all

air

from

the

system

before

turning

on

power

to

the

heater.

A

dry

-fired

element

(soft

annealed

or

blistered

and/or

completely

burned

off)

is

not

a

warranty

failure.

If

heater

does

not

heat:

1.

Check

filter

pressure

and

cleanliness.

2.

Turn

pump

on.

3.

Turn

Use

of

chlorinators

an

d

chemical

feeders:

AWARNING:

Chlorinators

and

feeders

that

are

misadjusted

may

cause

severe

and

rapid

corrosion

to

the

heater

heat

exchanger.

This

damage

is

not

covered

under

the

manufacturer's

warranty.

Chemicals

must

be

completely

diluted

into

the

pool

/spa

water

before

circulation

through

the

heater.

Check

the

following

conditions.

A.

B.

C.

D.

Chlorine

tablets

or

bromine

sticks

should

not

be

placed

in

the

skimmer.

Do

not

use

non

-stable

chemicals.

Chlorinator

must

be

installed

downstream

from

heater,

have

a

check

valve

to

prevent

chemical

back-up,

or

be

wired

in

such

a

manner

that

chlorinator

shuts

off

with

the

filter

pump.

Tether

"floaters"

such

that

they

will

not

be

drawn

to

the

skimmer.

Contactor

failures

or

chattering

contactors:

Principally

caused

by

dirty

filters

and

by

mar-

ginal

water

flow

conditions.

Filters

must

be

back

-

washed

and

the

water

flow

must

be

maintained

as

per

manufacturer's

installation

instructions.

In

addition,

contactor

failures

may

be

caused

by

undersized

field

wiring

creating

a

high

electrical

resistance,

and

low

voltage.

Contactor

failures

under

these

conditions

are

not

warranty

problems.

Lack

of,

or

insufficient

cleaning

and

back

-

washing

filter

skimmer

baskets

can

result

in

contactor

failure.

This

is

not

covered

under

the

certificate

of

warranty.

Winterization/Freezing:

If

your

heater

is

to

be

shut

off

and

exposed

to

freezing

temperature,

it

must

be

drained.

Water,

when

frozen,

will

expand,

damaging

your

tank.

Shut

off

or

disconnect

your

electrical

supply

to

the

heater

before

draining.

Follow

the

startup

instruc-

tions

before

you

restore

your

electrical

supply.

Freeze

damage

is

not

covered

by

the

limited

warranty.

Chemical

vapors:

Spa

maintenance

chemicals

may

produce

vapors

harmful

to

your

C

-SPA

-XI.

Never

store

chemicals

or

any

flammables

near

your

spa

heater.

Destruction

of

the

heater

by

corrosion

or

a

fire

can

result.

High

limit:

In

case

of

overheating,

your

C

-SPA

-XI

heater

will

shut

itself

off.

This

is

accomplished

by

the

use

of

a

manual

reset

high

limit.

To

place

the

heater

back

In

operation,

reset

the

limit

per

the

label

instructions

on

the

heater.

Water

flow:

Your

C

-SPA

-XI

must

have

an

adequate

flow

of

water

for

proper

operation.

(See

installation

and

start

up

procedures.)

Adequate

water

flow

removes

the

heat

produced

by

the

heater,

transfers

the

heat

to

the

spa

and

prevents

overheating.

Low

water

flow

usually

results

from

a

dirty

filter

or

improperly

adjusted

manual

by-pass.

Manual

by-pass

valves

should

be

set

so

that

the

outlet

thermometer

reads

6-8°F

above

the

spa

water

after

five

(5)

minutes

of

heater

operation.

The

recommended

minimum

flow

through

the

heater

is

12

GPM

(gallons

per

minute)

up

to

a

maximum

flow

of

60

GPM.

If

flow

exceeds

60

GPM,

refer

to

figure

3

and

install

external

by-pass.
