Shearing Hazard
DO NOT put fingers or hands etc. into the suction or discharge outlets.
Keep the protection covers in place until removal is necessary for
installation. Always replace the covers after inspection.
4.1
Initial Inspection for Damage
If any damage is found on receipt, notify the carrier and SPP Pumps Limited.
as soon as possible. Do not use the pump until cleared to do so by SPP
Pumps Limited.
Before installation carefully check that the pump was not damaged during
delivery or storage.
4.2
Oil Circuit Preparation
Make sure the entire oil circuit is perfectly clean and free from moisture and
foreign matter. The motor and bearings are designed for working in clean oil
only. Any contact with contaminants will cause serious damage.
To achieve the necessary cleanliness requirements and to remove any
particle contamination, NEW oil must be filtered into the system and flushed
through the circuit to waste. A witness filter can be fitted to the waste outlet
to determine when the system is clean. The oil in the system must conform
and be maintained to the cleanliness requirements of ISO 4406 level 17/13
for contamination.
4.3
Preparation for Mounting
Before installation, check that the pump mounting location is suitable for
accepting the pump unit, if in doubt refer to installation drawings. Ensure
that the equipment to which the pump is mounted can safely withstand all
static and dynamic loads.
4.4
Pump Preparation
Measure the electrical resistance of the insulation between the motor
windings and the frame. If the reading is under one megohm, dry out the
motor in a warm, dry, clean atmosphere, with a maximum temperature of
110
o
C.
Do not exceed 110
o
C or damage may occur to the insulation. Take care
that no damage occurs to the bearings or any other part of the pump
because of the drying process.
