Frost-free
ƒ
Take immediate countermeasures if there is a build-up of toxic or asphyxiating
gases!
ƒ
Work must always be carried out by two persons.
ƒ
Install lifting equipment: even surface, clean, firm base. Warehouse and installation
location must be easily accessible.
ƒ
Attach the chain or wire rope to the attachment points with a shackle. Only use lift-
ing gear that has been technically approved.
ƒ
Do not stay within the swivel range of the hoisting gear.
ƒ
Provide threading strip for the installation of the connection cables.
ƒ
Installation of switchgear: Observe information in the manufacturer's instructions (IP
class, overflow-proof, potentially explosive atmospheres)!
The lifting unit can be installed on various constructions (concrete, steel, etc.). Select
the fixation material which is suitable for the relevant construction. For correct installa-
tion, observe the following instructions for the fixation material:
ƒ
Avoid tearing or chipping of the construction surface, observe the minimum edge
distances.
ƒ
Ensure tight and secure installation, adhere to the prescribed borehole depth.
ƒ
Drilling dust impairs holding strength, always blow out or vacuum out the bore-
hole.
ƒ
Only use components (e.g. screws, anchors, mortar cartridges) which are in perfect
condition.
The pipework is subjected to different pressures during operation. Pressure peaks can
also occur (e.g. when closing the swing check valve) which may be several times higher
than the pump pressure, depending on the operating conditions. These different pres-
sures put a strain on the piping and the pipe adaptors. In order to ensure safe and fault-
less operation, the piping and pipe adaptors must be checked based on the following
parameters and designed according to the requirements:
ƒ
Pipes are self-supporting.
No tensile or compressive forces may act on the lifting unit.
ƒ
Pressure resistance of pipework and pipe adaptors
ƒ
Tensile strength of the pipe adaptors (= longitudinal force fit connection)
ƒ
Connect the pipes free of stress and vibrations.
ƒ
Provide a gate valve in the inlet and the pressure pipe on-site!
The pump chamber is installed in the following steps:
