3 Introduction
Study the instructions carefully and pay special attention to the warnings!
3.1 Introduction and general description
This instruction manual has been prepared as a guide for the persons who will be operating/handling the HLSD-2 Circular
Access Tank Covers.
Warning: The service personnel must be acquainted with the content of these instructions in order to avoid operating errors.
Incorrect use can be of danger to the user or a third party and can cause damage to objects and/or people.
You will find the information contained in this manual simple to follow, but should you require further assistance, our Technical
Sales Support Department and worldwide net of sales offices are pleased to help you.
NOTE
The illustrations and specifications contained in this manual were effective at the date of printing. However, as continuous
improvements are our policy, we reserve the right to alter or modify any unit specification on any product without prior notice or
any obligation.
The English version of the instruction manual is the original manual. We make reservations in regard to possible mistranslations in
language versions of the instruction manual. In case of doubt, the English version of the instruction manual applies.
3.2 Intended use
The end-user should verify:
- that the tank cover is in conformity with respect to tank, vessel or container size in which it is used.
- that the construction materials (both metallic and nonmetallic) are compatibility with product, flushing media, cleaning
media, temperatures and pressure under the intended use.
Alfa Laval covers are suitable for different applications (e.g.: filling, emptying, access for cleaning or inspection, general access
opening etc.).
Clients must specify the detailed version of each cover required. The client must determine the intended purpose of the cover
from the technical data of the whole container/vessel (including details such as working/design pressures and temperatures etc.).
6

4 Installation
Study the instructions carefully and pay special attention to the warnings!
4.1 Application
Outward opening manhole cover type HLSD-2 is used on top of pressurized tanks and containers where closeable means
of access to the interior of the vessel is required. HLSD-2 is approved and can be used on pressure vessels according to
PED 97/23/EC.
4.2 Working principle
HLSD-2 is secured in the closed position by swingbolts, which, together with the seal in the cover, ensure complete tightness.
The cover is attached to the frame by a rigid hinge, giving exact location of the cover in the closed position and designed to
stop the cover at an angle of 20-30° beyond the vertical position when opening.
7

5Operation
Study the instructions carefully and pay special attention to the warnings!
5.1 Safety regulations
Warning: All operators must be trained / certified to work in the area of the container operation and must abide by the site
safety regulations.
All work on the cover must be carried out by competent staff with knowledge of the relevant rules of operation
of container and pressure container.
When the removal of protection equipment is necessary for cleaning or maintenance purpose, assembly and
examination of protection equipment has to follow immediately!
Before opening the cover, check the pressure of the container. Only open the cover when the container is not
under pressure.
Conditions are not allowed to exceed pressure and temperature specified. The Pressure (PS) and Temperature
(TS) are written on each cover.
When filling and emptying the container, the regulations regarding contact of the liquid or content (e.g. foodstuff)
must be kept.
National rules regarding use and test frequency must be followed.
5.2 Components
Depending of the detailed version of the cover, specified by the customer, components are attached accordingly.
Typical components according to drawing:
- Screws complete (number according to description)
- Hinge / swivelling feature
- Screwed sight glass / circular sight glass
- Spring assist
- Limit switch
-Lockingbolt
- Safety grill
- Safety valve
- Etc. for other special items agreed
5.3 Weld into position
To tack in, frame and vessel wall have to be adjusted carefully.
By applying the tack weld, the weld crack has to be small. Short distances between the tack welds prevent deformation.
During the welding of the neck to the container, it is preferable to have the cover lid closed and the operational seal removed (to
be replaced by a temporary seal / spacer). This will give added rigidity to the neck when welding in and avoid heat transfer
damage to the seal.
After welding, gasket seating has to be checked against circular and plane. If there is a difference of more than 1 mm, gasket
seating has to be put in right form.
8

5Operation
Study the instructions carefully and pay special attention to the warnings!
5.4 Assembly
When surface treatment is completed (ground, pickled, polished, shot-blasted etc), all components have to be assembled
carefully.
Screws / Swing-pins must be assembled completely (i.e. securing the bolts with the safety cir-clips, clamp sleeve, washer and
nut / handle to be correctly assembled to the screws / swing-pins).
Before starting a process or putting the container under pressure / temperature, all equipment must be checked to ensure correct
functionality; (hinge, gasket seating, screws/swing-pins including all safety cir-clips assembled, locking bolt, nuts/handles etc.)
5.5 Material lifetime
As the customer selects the material by order, no warranty in relation to material lifetime is offered by Alfa Laval Kolding A/S. It
is the responsibility of the operator to make sure, that product coming in contact with the cover or seal, are suitable and the
materials and seal are sufficiently resistant to the product / conditions.
5.6 Closure of cover
The operator is responsible for the safe closure of the cover. Ensure before closing that the container is not occupied by
persons, animals or inadmissible objects.
Ensure before closing the cover that the sealing surface is free from any obstructions (i.e. body parts or equipment) as injury or
damage can occur.
Al parts relevant to security and pressure has to be checked visually before closing the cover. (e.g. gasket, gasket seating,
screws).
Cover has to be closed carefully without force. Look after good centralisation. Ensure seal is positioned correctly and
that contact area is clean.
Lid and neck should have a little lateral clearance, so that the gasket seating does not have metal contact.
Centre of lid flange has to enclose the gasket seating of the neck perfectly.
Screws/swing-pins are to be put in the correct position, so that the machined face of sleeves clings to the outside groove of
the lid flange.
The bolting arrangement must be tightened evenly and to a set torque when using a max allowable torque procedure in
several steps as follows:
A. 50% torque
B. 80% torque
C. Max. torque
Cross tightening of the bolting arrangement should be used when applying torque to the nut / handle (e.g. North, South, East,
West where appropriate).
The maximum torque for the screws is 40 Nm for M12 Screws and 60 Nm for M16 Screws.

5Operation
Study the instructions carefully and pay special attention to the warnings!
5.7 Opening of cover
The operator is responsible for the safe opening of the cover. Before opening the cover, ensure the container is checked to be
free from pressure, heat and chemical vapours.
If necessary, protective clothing and protective eyewear have to be used especially for high temperatures, for caustic or
toxic liquid applications etc.
Like with closing, all nuts / handles should be opened symmetrically. Cross opening of the bolting arrangement should be used
when opening the cover (e.g. North, South, East, West where appropriate).
Opened lid to be set down securely / carefully, to avoid damage to lid / seal (if possible use a spring loaded locking pin) and to
prevent lid falling downwards accidentally causing injury.
5.8 Cleaning
The complete cover has to be cleaned as per the recommendations of the manufacturer of the container.
It is the responsible of the operator to ensure that all cleaning agents used do not have an adverse affect on the cover materials
and the seal. Cleaning agents should be thoroughly removed after use.
During C.I.P., it is imperative that the temperature does not rise above the recommended temperature of the cover/seal causing
damage.
10

6 Maintenance
Study the instructions carefully and pay special attention to the warnings!
6.1 Maintenance
Cover has to be checked regularly for damage (e.g. gasket, gasket seating, nut / screw and complete swing assembly, hinge,
spring, etc. - Only Alfa Laval recommended spare parts to be used).
We recommend inspection of each cover at least annually against mechanical damage, corrosion and tightness.
