THE 6 ESSENTIAL POINTS

Control

the

delivery:

before

any

handling,

to

check

the

state

of

the

heat

pump

after

having

removed

the

packing

of

protection.

Any

degradation

transport

will

have

to

be

announced

on

the

form

of

transport

and

by

Letter

Registered

AR

under

48

hours

to

the

conveyor.

Importance

of

this

note:

it

is

essential

that

it

is

given

to

the

fitter.

We

advise

to

read

and

follow

with

attention

the

entirety

of

the

instructions

appearing

there.

Preserve

this

note

for

being

able

to

consult

it

constantly.

Standards

of

installation:

the

installation

must

be

carried

out

in

accordance

with

the

standards

in

force

for

this

type

of

apparatus,

and

by

respecting

the

instructions

of

the

manufacturer,

a

person

qualified

in

the

handling

of thermodynamic

machines

or

air-conditioning.

The

person

must

have

the

lawful

material

and

guarantee

of

a

training

of

approved

refrigeration

technician.

Any

defect

in

the

installation

can

cause

damage

on

the

individuals,

the

animals or

the

objects.

On

no

account,

the

importer

of

this

apparatus

could

not

be

made

responsible

for

this

damage.

Use

of

the

heat

pump:

this

heat

pump

is

intended

exclusively

with

use

for

which

it

was

conceived.

Any

other

use

non

in

conformity

and

random

will

be

regarded

as

dangerous

and

unsuitable.

Maximum

temperature

of

the

water

of

swimming

pool:

It

is

essential

to

maintain

the

temperature

of

water

below

the

value

recommended

by

the

manufacturer

of

the

swimming

pool,

in

order

not

to

deteriorate

its

lining

(liner

PVC).

Breakdown:

not

consider

any

attempt

at

breakdown

service;

any

even

inopportune

breakdown

will

have

to

be

announced

to

your

retailer

or

your

fitter.

Wintering,

maintenance:

instructions

appear

in

this

note,

it

is

essential

to

conform

to

it;

before

these

operations,

the

power

supply

of

the

heat

pump

must

be

cut.

Maintenance:

To

perpetuate

and

guarantee

the

performances

of

the

heat

pump,

it

is

necessary

to

make

carry

out

a

regular maintenance;

to

refer

for

that

to

the

instructions

of

maintenance.

In

the

event

of

resale

with

a

third,

it

is

imperative

that

this

note

is

included

with

the

material

if

the

new

owner

or

the



fitter

wishes

to

consult

it.

Any wrong handling can cause an important risk

being able to result in death

Any wrong handling can cause serious damage to

the user and the machine

TO NOT DO

To follow attentively

To be sure of the electric connections

To be sure of the disconnection of the plug

Never climb, rest on or put on something on the unit

Caution DANGER: electrocution risk

Do not put hands, do not touch

4

CAUTION

Do

not

climb

on

the

unit

or

try

to

move

it

when

installed.

Keep

out

of

the

reach

of

children

do

not

let

us

playing

near

the

unit.

Never

introduce

a

stick,

your

finger

or

others

in

the

air

inlet/outlet.

The

ventilator

runs

at

high

speed:

that

would

cause

a

very

serious

incident.

Important:

Well

clean

the

plug

If

dirtiness

adheres

to

the

plug

or

if

it

is

badly

inserted:

that

can

cause

a

fire

or

electric

shocks.

If

an

abnormality

(smell

of

burning

…

)

occurs,

stop

the

unit,

unplug

or

switch

off

the

electricity.

Do

not

clean

the

appliance

with

water.

Water

will

go

into

the

unit

and

will

destroy

the

insulation.

Do

not

connect

/

unconnected

the

unit

when

running

;

press

before

all

the

button

OFF.

Do

not

draw

on

the

power

supply

cable.

Well

have

in

hand

the

plug

to

disconnect

it.

Fire

hazard

could

occur due

to

the

wrenching

of

the

electric

cable.

Do

not

touch

the

plug

with

wet

hands.

It

will

caused

an

electric

shock.

By

stormy

weather,

cut

off

the

pump

to

avoid

the

damaged

caused

by

the

lightning.

First

off

all

the

heat

pump

is

stopped,

put

out

leaves

or

others

little

particles

blocking

the

air

inlet

vanes.

Verify

the

compatibility

of

the

network

with

the

data

written

on

the

heat

pump

before

beginning

the

installation.

The

other

disinfection

systems

such

as

electrolysis,

chemical…

are

not

recommended

for

a

good

running

of

the

pump.

The

pump

must

be

ready

before

these

systems.

For

an

optimal

running

of

the

heating

pump,

many

rules

must

been

respected:

A.

Use

-

The

appliance

must

be

able

to

be

watch

on

especially

so

that

children

do

not

play

around.

Attention:

When install pipeline for heat pump, user need to install an additional pressure reducing valve

(working pressure is less or equal to 3bar) in the water inlet pipe, for pressure reduction

and pressure stabilizing in the water supply system.

BEFORE

THE

STARTUP

OF

IT

IS

SIGNIFICANT

TO

INCLUDE/UNDERSTAND

THE

OPERATING

AND

THE

SETTINGS

OF

WHICH

YOU

WILL

TAKE

NOTE

IN

THE

FOLLOWING

PARAGRAPHS

3-4 Running of reversible heat pump :

By

using

the

free

energy

contained

in

the

ambient

air,

the

heat

pump

enables

to

heat

the

water

of

the

water

in

a

very

economic

way.

Your

heat

pump

is

a

heat

machine

that

can

transfer

the

heat

from

a

low

temperature

place

(ambient

air)

to

a

higher

temperature

place.

Running in heating mode :

The

heat

of

the

air

is

absorbed

by

the

cold,

liquid

refrigerant,

through

the

evaporator

(radiator

with

wings),

in

which

it’s

vaporized;

then

the

compressor

increases

the

pressure

and

the

temperature,

and

sends

it

into

the

condenser

(exchanger)

where

it

loses

its

heat

by

transmitting

it

to

the

water

and

it

comes

back

in

the

liquid

state;

it

loses

its

pressure

and

cools

again

into

the

pressure

reducer

before

returning

to

the

evaporator

for

a

new

cycle.

Running in cooling mode or defrosting mode

:

4

way

valve

enables

to

reverse

the

cycle

of

the

refrigerant

;

the

liquid

fluid

is

vaporized

into

the

exchanger

(that

becomes

the

evaporator)

by

taking

the

heat

of

the

water

of

the

water,

passes

into

the

compressor

which

heats

it

then

into

the

radiator

(which

becomes

the

condenser)

where

it

comes

back

at

the

liquid

state.

The fitter has to read the following notice and explain the instructions to the user.

5-1 Devices of control and safety:

The

heat

pump

is

equipped

with:

2

control

devices:



A

defrost

temperature

probe

located

on

the

evaporator,

starts

the

sequence.



A

thermal

located

on

the

5-2 Defrost operation:

1.

Defrost:

The

system

begins

to

defrost

if

the

following

three

terms

are

met

in

the

same

time:

a.

T4

5

minutes

c.

Compressor

runs

accumulative

total

for

45

minutes(the

interval

between

two

While

the

system

begin

to

compressor

and

fan

motor

stop

at

first

and

four

way

valve1

is

on

after

1

minutes

and

begins

to

work,

compressor

restarts

after

it

stop

for

3

minutes.

If

the

sensor

for

T4

is

damaged,

the

system

begins

defrosting

after

compressor

runs

continuously

for

45

minutes.

2.

Terms

exiting:



When

reach

3

minutes

and

T4

reaches

10

reaches

8

minutes,

defrost

exits

and

enter

stop

for

1

Compress

restart

after
