8.5 Pool Surface Pumps
8.5.1 Placement and Foundation
CAUTION – This pump is for use with
permanently-installed pools. Do not use
with storable/temporary pools.
CAUTION – The drain hole/pipe on the
bottom between pump housing and motor
must never be clogged or sealed. Blocking
the drain hole will result in an internal
build-up of water which will damage the
motor! Ensure that any drainage cannot
cause consequential damage! If necessary
provide a suitable drip pan.
CAUTION – If the pump is installed in a
humid area, effective ventilation and
aeration must be provided, in order to
prevent condensation.
CAUTION – The pump must be mounted
in horizontal position.
WARNING – The pump might heat up in
operation. The pump must not be installed
on combustible surfaces. Strong
incombustible surfaces should be used,
e.g. cement or stone surfaces.
Rain and weather protection – The pump is equipped
with IPX4-type motor protection. If it is installed outside, the
pump must be protected from rain and direct sunlight. This
will increase the durability of your pump.
Foundation – Installing the pump on a concrete founda-
tion is recommended. The foundation must be completely
even and level. Its purpose is to absorb vibration and strain
in addition to preventing stress on pipe flanges.
Connecting the pump to the foundation – Fastening
the pump to the foundation should be done exclusively by
means of M8 bolts or threads (dowels) in order to avoid any
movement of the pump unit.
