1.3 USES

DDS – DCS units are dehumidifiers for small swimming pools, thought for all the environments where the non-control of the humidity may cause damages to the structure.

Its use is recommended within the functioning limitations indicated in this manual.

Place the unit where there are not explosion or fire dangers, neither in vibrating areas or in presence of electro-magnetical fields. Furthermore, do not operate in ways which differ from those indicated and do not underestimate safety operations.

DDS-DCS units are projected for the use in swimming pools, that is to say in places with high concentration of chlorine and / or other corrosives. It is very important to leave the unit on as much as possible, in order to avoid the depositing of corrosives and, as consequences, the

probable damaging of the unit itself.

- The unit in stand-by (with dehumidification and heating non-active) is set by default to grant the ventilation at its

minimum; it is possible to change this set and make the ventilation stop when the unit is in stand-by. It is recommended not to change this set.

- The unit will be turned off necessarily for the ordinary and extra-ordinary maintenance; after the maintenance operations,

it is recommended to turn the unit on again as soon as possible.

- Do not stop the unit during seasonal pauses.

All these information are useful in order to prevent the depositing of chlorine which could damage the unit.

1.4 RESIDUAL RISK AREAS

Due to the peculiar functionality of the unit, in some areas of it, there are residual risks which was not possible to elude during the project neither to reduce. Each operator should be aware of the residual risks in this unit, in order to avoid accidents.

Residual risk areas:

- Short circuit or fire caused by short circuit risk;

- Explosion danger because of the presence of under pressure circuits or pollution due to the refrigerant gas in the circuit;

1.5 INTERVENTION AND MAINTENANCE

It is useful to remember that the manual can not substitute the suitable experience of the user; for some maintenance operations, the manual represents a reminder of the main activities for competent operators, who have attended, for instance, instructive courses promoted by the manufacturer.

Please, read carefully the following suggestions:

- a preventive and constant maintenance grants the high safety standard. Do not postpone the required reparations and make sure they will be done by qualified staff and by using exclusively original spare parts;

- schedule carefully each intervention;

- operators workplace should be clean and free from objects which could limit their movements;

- operators should avoid inaccurate operations and positions, in order not to compromise their balance;

- operators should pay attention to risks of trapping or cloths/hair entangling in moving parts; the use of a cap is strongly recommended for people with long hair;

- necklaces, bracelets and rings could be dangerous;

- the place should be suitably lit up; an inadequate lighting can be dangerous;

- wait approximately half an hour after the turning off of the machine, before intervene for any maintenance, in order to avoid burns;

- do not repair high pressure damaged pipes with welding;

- during installation and maintenance, fluids in the refrigerant circuit and electric parts, can generate dangerous situations;

- reduce, as much as possible, the opening time of the refrigerant circuit: this because, even for a short time, the air exposition of oil causes the absorption of high humidity quantities and this leads to the creation of weak acids;

- each intervention on the unit should be made by qualified staff;

- before starting a maintenance intervention, make sure the power supply has been turned off;

- make sure the safety devices work correctly; if not, do not turn on the unit;

- use only equipment suggested by the manufacturer of the unit, in order to reduce the possibility of accidents due to low quality equipment;

-after the cleaning of the unit, the operator should verify that there are not damaged parts; in case he finds out something wrong, he should ask for the intervention of a maintenance technician;

- the place should always be clean and properly tidied up, because smearing of oil or grease could cause sliding or fallings;

- the use of inflammable fluids during cleaning operations is forbidden.

During the cleaning operations, do not use gas oil, oil or solvent because while the first leaves an oily patina, which leads to dust attraction, the latter can damage the paint and leads to the creation of rust. If some water seeps into the electrical devices, it will produce oxidation, which can cause the dysfunction of the unit. You should not use water or steam spout on sensors, connectors and other electrical parts.

Please pay attention to the integrity of pipes and other devices, which could wear out. Check that there are not leaks of fluids and other dangerous substances. If something like this occurs, the operator should not turn on the unit before the reparation.

7.3 HYDRAULIC AND ELECTRICAL CONNECTIONS

7.3.1 HYDRAULIC CONNECTIONS

When preparing the hydraulic connection, it is compulsory to follow the indications below and to follow the National dispositions.

Do not twist the unit connections. With a key, block the connection and, with another key, fix the connecter.

Fix the pipes with flexible curves in order to avoid the transmission of vibrations and to compensate the thermal dilatations. It is recommended to install the following components on the pipes:

- zone valve (if not required as options);

- temperature and pressure indicators for the ordinary maintenance and control of the group. The pressure control allow to evaluate the correct functioning of the expansion vase and to highlight in advance eventual water losses in the plant;

- interception valves to insulate the unit from the hydraulic circuit in case of maintenance;

- metal filter (incoming pipe) crossed with strict meshes (less than 1 mm) to protect the exchanger from the impurities of the pipes. This phase is necessary overall for the first starting of the unit;

- escape valves, to place in the higher zones of the hydraulic circuit, in order to allow the purging of air. On the internal pipes there are manual escape valves for the purging on board; this operation should take place when the tension is off;

- discharge tap and, if necessary, drain tank to allow the empty of the plant during maintenace processes;

- in case of process applications, it is recommended to install an decupling exchanger, in order to avoid the possible dirtying of the exchangers.

It is fundamental that the water income occurs where signalled by the label “water income”. If not, the counter-current circuit is not respected and the risk of misfunctioning, blockage or broken-up of the unit is real.

Dimensions and positioning of the hydraulic connections are indicated on the dimensionals drawings.

The hydraulic circuit should be realized in order to grant a constant water flow (+/-15%) in every functioning conditions.

7.3.2 DRAIN CONDENSATION CONNECTION

Use a flexible rubber with an internal diameter of 16 mm.

The inclination of the drain pipe should permit the water down flow outside. If not, the bulb collection will fill up and there will be water loss.

of the plant. Clean contact, no supplying.

Clamps 103 - 104 are for the connection of a zone valv, a water valve or a water pump (max 1A) to manage the water supplying to the unit. For equipment with consumption over 1A, interpose a contactor or a power-relai. The drive is in 230V.

Clamps 105 - 106 are for the on/off at distance; connect a contact from a switch or from a board for the management of the unit turning on at distance Connect only a clean contact.

Clamps 107 - 108 are for the dehumidification on/off; connect a contact from a switch or from a board for the management of the dehumidification at distance. Connect only a clean contact.

Clamps 109 - 110 are for the heating on/off; connect a contact from a switch or from a board for the management of the dehumidification at distance.

The contact functions only if the option hot water coil with valve or electrical heaters has been bought.

Connect only a clean contact.

On/off contacts (at distance – dehumidification – heating) have to be set on the board during the first start; please make reference to the dedicated chapter.

ESAMPLES:

- The user ask to turn on / turn off the unit from a on-wall switch: I decide to use the on/off at distance, connect the 2

cables of the switch to the clamps 105 -106 and during the first start of the unit activate the on/off at distance.

- I have a drive board from the thermo-regulation of the plant with a clean contact for the dehumidificaion and a clean

contact for the heating: I decide to use the dehumidification on/off contact and the heating on/off contact, connect the contact to the drive board for the activation of the heating on the clamps 109 – 110 and during the first start activate the contact for dehumidification an heating.

1. Recirculation: OFF, MIN, MEDIUM or MAX

2. Dehumidification: MEDIUM or MAX

3. Heating: (if present): MEDIUM or MAX, connected to the speed in dehumidification

It is recommended not to set the recirculation speed on OFF, because each time the unit goes in stand-by, it turns off the ventilation and the chlorine present in the swimming pool could damage the components of the unit .

The screen 2 of the installer menu allows to modify the timer which signals the filter cleaning.

On the left you see the screen 3 of the installer menu, which allows to modify the differentials that manage the request for dehumidification.

On the left you see screen 4 of the installer menu, which allows to modify the differentials that manage the request for heating.
