3.4.2 Temperature
The storage temperature should not exceed 25 °C
(77 °F) and should not. Drop below -10 °C (14 °F)
[Neoprene +12 °C (53.6 °F)]. Adhesives and
solutions should not be stored below 0 °C (32 °F).
Not keeping these limits will result in detoriation and
affect the service life.
The effects of low temperature are not permanently
deleterious, but care should be taken to avoid
destroying them during handling. When articles are
taken from low temperature storage for immediate
use, their temperature should be raised to about 20
°C (68 °F) throughout.
3.4.3 Humidity
Moist condition should be avoided; storage
conditions should be such that condensation does
not occur. Favorable humidity should be about 65
per cent.
3.4.4 Light
The articles should be protected from light, in
particular direct sunlight and strong artificial light with
a high ultra-violet content. Unless the articles are
packing in opaque containers, it is advisable to
cover the windows of storage rooms with a red or
orange coating or screen.
3.4.5 Oxygen and Ozone
As ozone is particularly deleterious, storage rooms
should not contain equipment that is capable of
generating ozone, such as electrical equipment,
electric motors or other equipment which may give
rise to electric sparks or silent electrical discharges.
Combustion gases and organic vapors should be
excluded, as they may give rise to ozone via
petrochemical processes. Solvents, fuels, lubricants,
chemicals, acid, etc. should not be stored in this
room.
3.4.6 Deformation
The articles should be stored in a relaxed condition
free from tension, compression or other deformation.
(O-rings should not be stored hanging up on a
hook).
4 INSTALLATION
Equipment operated in hazardous locations
must comply with the relevant explosion protection
regulations. See section 1.6.4, Products used in
potentially explosive atmospheres.
All equipment must be grounded.
4.1 Location
Fulfill the following requirements:
•
Accessibility for operation and inspection and
space for maintenance
• Simple piping layout, no pipe bends immediately
preceding suction nozzle
•
Suction line as short as possible for minimum
suction losses
•
Ample headroom to lift components for
maintenance
4.2 Foundation
There are many methods of installing
pump units to their foundations. The correct method
depends on the size of the pump unit, its location
and noise vibration limitations. Non-compliance with
the provision of correct foundation and installation
may lead to failure of the pump and, as such, would
be outside the terms of the warranty.
The base plate should be mounted onto a firm
foundation, either an appropriate thickness of quality
concrete or sturdy steel framework. It should NOT
be distorted or pulled down onto the surface of the
foundation, but should be supported to maintain the
original alignment.
Anchor bolts must be in accordance with the foot
bolt holes. Use anchor bolts of accepted standards
and sufficient to ensure a secure fitting in the
foundation. Particularly, this applies to individual
plates where the anchor bolts have to withstand the
driving torque.
