1.3 INTENDED USE

The DDS –DCS –DVS –DOS units are dehumidifiers for small swimming pools with exposed, on technical room and false ceiling

installation, designed for use in all environments in which failure to control humidity can cause damage to the structure.

It is intended for use in swimming pools treated with chlorine, not for use in salt swimming pools.

Its use is recommended within the operating limits indicated in this manual.

Position the unit in environments where there is no danger of explosion, fire, where there are

vibrations or electromagnetic fields. It is also prohibited to operate in any way other than that

stipulated or disregard required safety operations.

The units are designed for use on swimming pools or places with the high presence of chlorine and

other corrosive substances. It is extremely important to leave the unit always on in order to avoid

the depositing of corrosive substances and therefore its probable damage.

-The unit set to OFF from the display on the machine, after 180 minutes will be reactivated in STAND BY operating mode (no

air treatment, ventilation at minimum speed).

-The unit with dehumidification and inactive heating is factory set to keep the ventilation to a minimum.

-The unit will be switched off and disconnected necessarily for ordinary and extraordinary maintenance; it is good practice

to perform maintenance, to power it up and to turn it back on as soon as possible.

-Do not stop the unit for seasonal breaks.

All these indications are used to prevent the formation of chlorine deposits that could damage the

unit.

The normal process of air dehumidification inevitably leads to heating of the same. It is advisable

to take it into consideration the temperature of the pool environment.

1.4 RESIDUAL RISK AREAS

In some areas of the unit there are residual risks that could not be eliminated at the time of

design or delimited with guards given the particular functionality of the unit. Each operator

must be aware of the residual risks present in this unit in order to prevent accidents.

Residual risk areas:

-risk of short circuit and fire caused by short circuit;

-risk of explosion due to the presence of pressurised circuits and risk of pollution due to the presence of refrigerant in the

circuit;

-risk of burns due to the presence of very hot pipes:

-risk of shearing.

1.5 INTERVENTION AND MAINTENANCE

It is important to remember that the user manual can never replace adequate user experience. This manual represents a reminder

of the main activities to be performed by operators who have received specific training, for example by attending training courses

held by the manufacturer, with reference to particular maintenance operations.

Carefully read the following recommendations:

- constant and precise preventive maintenance always guarantees the high operational safety of the unit. If there are some

necessary maintenance interventions, do not delay them and make reference only to qualified operators and original spare-parts;

- schedule each task with care;

- The operators’ working space should be clean and free in order to grant the necessary movements without dangers.

- Operators should avoid clumsy operations, in uncomfortable conditions which can compromise their balance.

- Operators must pay attention to the risk of clothing and/or hair being caught or entangled in moving parts. A cap should be worn

to keep long hair in place.

- The use of chains, bracelets and rings can also be dangerous.

- Even the use of necklaces, bracelets and rings can be a danger. The working place should be correctly lighted; insufficient or

excessive lights can be a danger;

- wait about 30 minutes after switching the unit off before performing any maintenance in order to prevent burns;

- do not repair high pressure pipes with welds;

- pressure liquids on the refrigerant circuits and electrical components presence can be dangerous

during installation and maintenance operations;

- reduce as far as possible the time of opening for the refrigerant circuit. Oil exposition to air causes the absorb of high quantity of

humidity and this leads to the creation of weak acids;

- only qualified personnel may perform work on the unit;

- before performing any kind of work or maintenance on the unit, make sure it has been disconnected from the power supply;

- make sure that safety devices work properly and that there are no doubts about their functioning; if not do not start the unit;

- use only tools prescribed by the unit manufacturer. In order to avoid personal injury, do not use worn or damaged, low quality or

improvised tools;

once the unit has been cleaned, the operator must check that there are no worn or damaged

parts or parts that are not firmly secured; where these are found, request the intervention of the

maintenance technician;

- always keep the area in which the unit is kept clean and tidy. Oil and grease stains, broken tools or broken pieces are harmful to

persons as they can cause slips or falls;

- it is prohibited to use flammable fluids to clean the unit.

Do not use diesel, petroleum or solvents to clean the unit as they leave an oily film that encourages dust to settle, while solvents

(even if weak) damage the paintwork and encourage the formation of rust. If a jet of water penetrates the electrical equipment, the

contacts oxidise and the unit may malfunction. Therefore, do not use jets of water or steam on the sensors, connectors or any

electrical part.

Make sure that the pressurised pipes, or other components subject to wear, are intact. Also make sure there are no leaking fluids or

hazardous substances.

Should there be a leak, the operator must not restart the unit before having resolved the problem.
