Operation and assembly instructions
for the hand operated pump
Model No.: 356010
1. Preparation
The hand pump should be positioned close to the cistern and mounted on a cement base with
a recess to accommodate the hose. Please note: A maximum 6 m suction height may not be
exceeded. When planning and laying the suction hose it ought to be clear that as few 90°
bends as possible should occur and if feasible, no 90° bends at all.
If the installation of an electrical pump is also intended, then it is important to ensure that this
has been planned with its own separate suction system. If the two pump systems are both
connected to one suction system, then there is the probability that air will be drawn through
the pump that is not in operation and this will lead to a loss of performance.
2. Installation of the pump
-
Secure the pump stand to the cement base by means of the 4 fixing holes at the bottom.
-
Draw the hose of the suction system through the empty conduit and up through the pump
stand.
-
Screw the connection nipple onto the pump body
(Teflon tape must be used. Attention: When using
Teflon tape around a thread, then even the smallest
counter-clockwise (screwing out) movement will
damage the seal, if this occurs then the old tape
must be removed and new tape applied).
-
To connect the hose correctly to the connection
nipple, a 1 ¼“ hose connection (Type.-Nr. 330014)
should be used.
-
Note: The hose should not be cut too short as this
will make the connecting through the pump stand
more difficult.
-
The hose is then secured using a hose clamp.
-
Attention: Before the suction hose is secured to the
hose connection it is necessary to fill the suction
hose with water (primed).
-
When this has been completed the pump body can be mounted and secured to the pump
stand using the 4 fixing screws.
3. Service
If after a period of years the pump no longer delivers its full performance then it may be
necessary to replace the seals (Type.-Nr. 356502).
To prevent frost damage during the winter months, it is necessary to dismount the complete
pump body and store in a frost-free environment.
Don’t forget: When re-mounting the pump the following spring that the suction hose must be
re-filled with water (primed).
