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

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

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.

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.
