4.4 Adjustment of cable length for float

switch

The difference in level between start and stop

can be adjusted by changing the free cable

length between the float switch and the pump

handle.

• An increased free cable length will result in

fewer starts and stops and a large difference

in level.

• A reduced free cable length will result in

more frequent starts and stops and a small

difference in level.

The free cable length must be a minimum of 4

in. (100 mm) and a maximum of 14 in. (355 mm).

The stop level must be above the inlet strainer to

prevent the pump from taking in air.

Fig. 5 Start and stop levels

The start and stop levels vary according to the

cable length.

Manual operation can be achieved in one of two

ways:

• Unplug both the pump and the float switch

from the wall socket. Insert the pump plug

into the wall socket.

• Keep the float switch in a high position by

attaching it to the outlet pipe/hose.

4.5 Electrical connection

The electrical connection must be carried out in

accordance with local regulations and follow the

National Electrical Code (USA) and the

Canadian Electrical Code. The pump must be

grounded. The operating voltage and frequency

are marked on the nameplate. Make sure that

1. Garantie limitée

Les produits fabriqués par Grundfos Pumps Cor-

poration (Grundfos) sont garantis, uniquement

pour l'utilisateur initial, exempts de défauts de

matériaux et de fabrication pour une période de

24 mois à compter de la date d'installation, mais

au plus 30 mois à compter de la date de fabrica-

tion. Dans le cadre de cette garantie, la respon-

sabilité de Grundfos se limite à la réparation ou

au remplacement, à la convenance de

Grundfos, sans frais, FOB de l'usine Grundfos

ou d'un atelier de maintenance autorisé, de tout

produit de fabrication Grundfos. Grundfos

n'assume aucune responsabilité quant aux frais

de dépose, d'installation, de transport ou pour

toute autre charge pouvant survenir en relation

avec une réclamation au titre de la garantie.

Les produits vendus mais non fabriqués par

Grundfos sont couverts par la garantie fournie

par le fabricant des dits produits et non par la

garantie de Grundfos.

Grundfos n'est responsable ni des dommages ni

de l'usure des produits causés par des condi-

tions d'exploitation anormales, un accident, un

abus, une mauvaise utilisation, une altération ou

une réparation non autorisée ou par une installa-

tion du produit non conforme aux notices d'ins-

tallation et de fonctionnement imprimées de

Grundfos ainsi qu'aux codes de bonnes pra-

tiques communément acceptés. La garantie ne

couvre pas l'usure normale.

Pour bénéficier de la garantie, il faut renvoyer le

produit défectueux au distributeur ou au reven-

deur de produits Grundfos chez qui il a été

acheté, accompagné de la preuve d'achat, de la

date d'installation, de la date du dysfonctionne-

ment ainsi que des données concernant l'instal-

lation. Sauf disposition contraire, le distributeur

ou le revendeur contactera Grundfos ou un ate-

lier de maintenance autorisé, pour obtenir des

instructions. Tout produit défectueux renvoyé à

Grundfos ou à un atelier de maintenance doit

être expédié port payé ; la documentation rela-

tive à la déclaration de sinistre et à une autorisa-

tion de retour de matériel éventuelle doit être

jointe, si elle est demandée.

Grundfos n'assume aucune responsabilité en

cas de dommages indirects ou consécutifs, de

pertes ou de dépenses résultant de l'installation,

de l'utilisation ou de toute autre cause. Il n'existe

aucune garantie, explicite ni implicite, y compris

la qualité marchande ou l'adéquation pour un

usage particulier, en dehors des garanties

décrites ou mentionnées ci-dessus. Certaines

juridictions n'autorisent pas l'exclusion ou la

limitation des dommages indirects ou consécu-

tifs, et certaines juridictions ne permettent pas

de limiter la durée des garanties implicites. Il se

peut donc que les limitations ou exclusions men-

tionnées ci-dessus ne soient pas applicables

dans votre cas. Cette garantie vous donne des

droits légaux spécifiques. Il se peut que vous

ayez également d'autres droits qui varient d'une

juridiction à l'autre.

Les produits qui sont réparés ou remplacés par

Grundfos ou par atelier de maintenance auto-

risé, en vertu des dispositions de ces conditions

de garantie limitée, continueront à être couverts

par la garantie Grundfos uniquement pendant le

reste de la période de garantie initialement fixée

à la date d'achat d'origine.

4.1 Raccordement de la tuyauterie

Les conduits en acier fileté ou en plastique

rigide peuvent être vissés directement dans l'ori-

fice de refoulement 1,5" NPT. Pour une installa-

tion fixe, il est conseillé d'installer un raccord, un

clapet de non-retour et un clapet d'isolement

dans le conduit de refoulement.

Autres recommandations :

• Pour les installations temporaires ou

mobiles, un conduit de refoulement en plas-

tique peut être utilisé avec un raccord vissé

ou un raccord pour flexible adapté.

• Sceller les filetages à l'aide de ruban adhésif

4.2 Espace restreint

Une fois la pompe installée dans un équipement

fixe avec interrupteur à flotteur, et la longueur de

câble réglée à la valeur minimale de 4 po (100

mm), les dimensions minimales du puisard, du

bassin ou de la fosse doivent être celles indi-

quées en fig. 2.

En outre, le puisard, la fosse ou le bassin doit

être dimensionné en fonction du rapport entre le

débit d'eau du puisard, du bassin ou de la fosse

et la performance de la pompe.

Fig. 2 Dimensions d'installation minimales

4.3 Lieu d'installation

La pompe peut être utilisée verticalement ou

horizontalement avec la sortie d'évacuation

comme point le plus haut de la pompe. Voir fig.

pine d'aspiration ne risque pas d'être bouchée

par de la boue ou des matériaux similaires.

Pour les installations fixes, le site d'installation

doit être débarrassé de la boue, des cailloux,

etc., avant l''installation de la pompe.

Il est recommandé de placer la pompe sur une

fondation solide. Voir fig. 4.
