Instruction manual
Instructions for use and important information.
Important information about function. Failure to heed
can impair function.
▪ Legal information.
▪ Personnel requirements
Prior to starting work, the fitter must read, under-
stand and heed these installation and operating
instructions.
P HKV-D manifolds for underfloor heating may only
be installed, adjusted and maintained by trained
specialists. Trainees may only work on the product
under the supervision of an experienced person.
Only if the above instructions have been adhered to
will the manufacturer accept any liability in line with
statutory provisions. Every instruction contained in
these installation and operating instructions is to be
heeded when using the P HKV-D manifolds.
Correct use
P HKV-D manifolds are used for distributing and regu-
lating the volume of flow in low temperature under-
floor heating systems and underfloor cooling systems
inside buildings. The installation of P HKV-D manifolds
must take place inside buildings, sheltered from
weather conditions.
P HKV-D manifolds are to be operated using heating
water as per VDI 2035. In the case of systems, the
heating water of which contains corrosive particles or
other contaminants, dirt traps or filters with a mesh
size of no more than 0.8 mm are to be fitted in order to
protect the measuring and control devices.
The max. permissible continuous operating pressure is
6 bar. The max. permissible test pressure is 9 bar.
Using the manifolds for any purpose other than that
set out in these instructions constitutes improper use.
The manufacturer accepts no liability for damage
resulting from improper use of the manifolds. For
safety and guarantee reasons, no conversion or modi-
fication is permitted.
The manufacturer accepts no liability if connections
and accessories made by other manufac-turers are
used.
Installation / Commissioning
Installation in manifold cabinet
The manifold headers are fitted to the sliding C profile
rails, using the supplied bolts. Please heed the relevant
installation instructions.
Hydraulic connections
P HKV-D manifolds are supplied with a 1" ball valve set
plus a flush-and-fill unit.
The manifold headers each have a G 1" male thread for
fitting the ball valve and the flush-and-fill unit, with
flat joints. Tighten the compression nut with an SW 27
open-ended spanner/ring spanner, holding the mani-
fold. When connecting pipes to connections, please
see our pipe installation instructions.
Flushing and filling the heating circuits
Hoses with 3/4" connections tubes are screwed to the
hose of the feed taps to fill the heating circuit mani-
fold. Slowly open and close the valves connections to
operate the flush-and-fill unit.
▪ During the filling and flushing process, the 1" ball
valves on the flow and return headers must remain
closed, otherwise the high water pressure might
damage the heating system or might acti-vate the
safety valve. Only fill and flush the manifold in the
direction of flow! Please avoid high differential pres-
sure (> 1 bar) and pressure shocks.
▪ If a mixing unit (art. 218138-001 or 218139-001)
with or without high temperature breaks is installed
at the manifold, you must remove the brackets on
which the manifold is installed and use the collars
provided in the packaging of the mixing unit, in
order to get the right interaxle spacing.
