Intended purpose

-Z are fixed/loose flange steel constructions suitable

for sealing structures with tanking membranes or thick coating (black

tank) with DIN 18195/DIN 18533/DIN 18535. All models are

suitable for installation on the wall/ceiling/floor. -Z

gasket inserts are used to safely seal the annular space between the

core bore/casing and the medium pipe/cable/smooth-walled cable

conduit to be installed.

Please note

• G asket inserts are not secure points or support bearings; they are

only used for elastic sealing of pipes/cables.

• Before installation, clean the core bore/casing and pipe/cable

carefully. Smooth out uneven points in the surface. We also rec-

ommend sealing the core bore with Aquagard (Curaflex accesso-

ry), especially in cases where water pressure is a consideration.

• Distances to other components, such as building edges and

channels, wall connection, can be found in DIN 18533.

• The relevant FHRK standard (minimum seal width) can be found

on the product label.

• When installing the sealing system, the applicable accident pre-

vention regulations, VDE rules, the applicable national health and

safety regulations, and the rules and policies of your company

must all be observed.

• The applicable national regulations governing the laying and

filling of pipes and cables must be observed.

Installation conditions

• B reakouts, cracks and/or cavities in waterproof concrete core

bores should be smoothed in advance.

• Casings must be rigid enough to withstand the compressive

forces from the gasket insert and must have a smooth, circular

inner surface. If casings are damaged they must be tested in

advance for usability.

• The conduit (cable or pipe) to be sealed must be cleaned in

advance and must not have any axial depressions or elevations in

or around the sealing area.

• Compress the substrate and pipe substructure well before laying

the pipe/cable, so that no sinking is possible.

• In addition to the usual standard tool, you also need the following

tools and equipment in order to properly install the gasket insert:

Tools:

1 torque spanner

1 extension

1 hexagon socket

(size see installation steps)

Equipment:

Lubricant

Cleaning agent (solvent-free)

Calliper gauge

Cleaning cloth

• Sealing components for the medium pipe/cable/cable conduit

must be installed in a waterproof concrete core bore or a pre-

installed casing.

• T here must be no cracks or breakouts on the wall surface around

the fixed flange.

• The fixed and loose flange must be clean and free of dust and

grease.

• In the case of flange designs under DIN 18195/DIN 18533, distan-

ces should generally be arranged as follows:

Outer edge of flange to outer edge of flange or to other com-

ponents, such as building edges and channels, wall connections,

at least 150 mm for non-pressing water and at least 300 mm for

pressing water.

In the case of expansion joints, distances of at least 300 mm for

non-pressing water and at least 500 mm for pressing water must

be observed, unless greater distances are required for processing

reasons.

Reduced torque may be necessary for thin plastic pipes, in order to prevent damage to the pipe. After installation

visually inspect the installation to ensure that the gasket insert is touching the pipe and the core bore on all sides.

Swapping the screws makes it possible to change the

tightening side of the gasket insert (switching the tight-

ening option from the ‘water side’ to the ‘dry side’ and

vice versa). HKD DOMO-NW-Z or HKD DOMO-DW-Z

(option A) changes to HKD DOMO-NW-Z-K or HKD

DOMO-DW-Z-K (option B) when swapped.

Place the gasket insert into the casing/core bore and

lightly secure by tightening the nuts (A). Drill dowel

holes through the component (10 mm Ø, min. 70 mm

deep). Insert the dowels and hexagonal socket screws.

Tighten the hexagonal socket screws (B). Smooth out

the transition from the fixed flange to the wall with

grout (C). Loosen the nuts (A) again.

Minimum drill hole depth d ≥ 70 mm.

Dowel length h = 50 mm.

Drill hole diameter dB = 10 mm.

Cut the membrane (A) and necessary packings (B), if

any, for loosely laid membranes in accordance with

the membrane manufacturer’s specifications (use

loose flange as template). Position the packings and

membrane on the fixed flange (C). When cutting the

membrane, ensure that its surface is not damaged in

the process. Use a punch to create the holes for the bolts

(M12 = 16 mm, M20 = 24 mm). Alternatively, apply

ready-to-use Curaflex

1775 packings (not included in

scope of delivery) to both sides of the membrane(s).

Position the packings and membrane on the fixed

flange. Important: the membrane must not have any

kinks, folds, bumps, sticky points or similar in the area

around the fixed and loose flange. Place both halves

of the loose flange with the face towards the packing/

membrane. Mount the washers and nuts.

Tighten the nuts, alternating cross-wise with several

turns each. Torques can be found in DIN 18533 or the

membrane manufacturer’s information.
