Unpacking and installing Schenk ZHF filter blocks.
Upon delivery in the presence of the freight forwarder, make sure to inspect packaging for signs of damage, any damage to packaging or equipment should be reported immediately to the Freight Company, insurance company and TT Filtration.
The filter and associated parts will usually arrive in seaworthy wooden crates, if not opened immediately they should be stored in dry, dirt and dust free environment, protected from moisture and aggressive gases.
Storage instruction form Pall and its sub suppliers should be followed.
Unpacking:
The filter is usually in a horizontal position, the box needs to be broken down and the filter lifted out horizontally (make sure the filter is free of any tie down and packaging residue before lifting it out of the box). For lifting use the lifting points on the top and one of the legs.
The filter is usually brought in horizontally and raised vertical once it reaches it final position, it is lifted by the 3 lifting eyes in the lid.
Mounting:
Lift the filter over the 3 floors anchor plates, once the filter is positioned, use thin stainless shims under the intermediate support plate to assure the filter is absolutely vertical prior to s[pt welding the intermediate plate to the floor anchor plates.
(Use a machined horizontal surface on the vessel and a mechanics level to assure the level mounting).
Once the filter is sitting level and all 3 feet have been spot welded to the floor plates, processed to solidity weld the intermediate plates on all 4 sides to the floor plates, checking level as you go to assure against pull from the welds.
Assembly:
Once the filter is secured, insertion of internal elements and piping can proceed.
My recommendation is to the install the internals first, which requires removal of the filter lid (that way the elements will be out of the way and protected in the filter).
Open the clamps and remove the lid (either using the lift integrated with the filter, or with external crane, better, as the lid will have to be stored away from the filter), remember to support the lid on wood blocks, up from the floor.
Bring in the element boxes and open to sort out what pieces go in first.
(There is a bottom support ring, scavenge elements, separation element, main elements and a top compression spider, in that sequence).
Once the elements are in, the lid can be clamped down and general piping works proceed.
The transportation plug should be exchanged for the vent plug in the filter gear drive at this point.
The filter position is the base for positioning all additional equipment.
The main parts next would be the dry DE discharge tank which has flat none adjusting foot plates that needs to be fastened with bolts to the floor (high horizontal forces when receiving discharge from filter).
(The tanks will come in separate boxes, horizontal or vertical, pending on the general shape of the tank. Piping and small equipment will arrive in several smaller boxes).
The remaining equipment will have on the floor surface support plates and adjustable legs.
Large pipes should be laid out horizontally to prevent low spots and attached to anchored equipment to allow correct placement of light piping, wiring and additional equipment.
All of this work should be standard piping and wiring work and should follow the site rules for this work.
