PHP A-4, 6, 8 & 9 Instruction Manual / General
1 General
1.1 Tender text
PHP for lossless storage of the expansion volume and for
pressure maintenance in closed heating, climate and cooling
systems. Designed and manufactured acc. to regulations of
EN 12828 and SWKI 93-1.
The PHP device is a nicely shaped, self-contained unit
with a pleasing design. It is designed for a modular
combination with external expansion vessels (max. 0.5 bar).
The connections for suction pipe and overflow pipe are
situated at the back of the device.
The control unit is built very compact with one resp.
two low-noise pressure maintenance pump(s) which are
executed as multistage centrifugal pump(s) with high
quality floating-ring type shaft seal. Also the PHP hydraulics
includes one resp. two continuously regulating, mechanically
set overflow valve of the expansion flow. High-precision
measuring of the plant pressure. Hydraulic connections and
necessary shut off devices for on-site piping are factory
provided on the left side of the control unit (possibility for
rebuilding to the right side of the control unit). Temperature
monitoring of the media streaming into the vessel.
Prepared connection point for mounting a makeup module
for a per litre accurate measuring. Combinable with an
option for water softening for standardized makeup water.
Prepared connection point for mounting a degassing module
for automatic and economic low pressure degassing, based
on the principle of pressure drop. The connection and the
necessary shut off device for the degassing pipe is situated
at the back of the control unit.
All operations are controlled by the microprocessor electronics.
The operator panel is situated ergonomically and contains an
illuminated 4-line text display. The handling is thought-out and
a lot of languages are supported. The measure and control
unit is executed in a closed electrical cabinet. Four potential-
free signalling contacts (fault, warning, makeup in operation,
device operation enabled).
For more signals two additional expansion modules
can be installed easily in prepared mounting positions.
Remote monitoring can be done also via PHP SMS module
or PHP bus module. External temperature monitoring
via an optional temperature sensor at the connection point
is prepared too.
Max. operation temperature of the plant: 110 °C
(with cooling vessel)
Max. temperature at the connection point: 70 °C

PHP A-4, 6, 8 & 9 Instruction Manual / Mounting
2 Mounting
2.1 Installing the device
The PHP device must be installed on a horizontal and solid
floor and it must be set up vertically by using the adjustable
stands (1). The four holes on side of the socket can be
used to transport the device (for example by inserting
2 pipes, max. 1”).
The implementation into the system return must be executed
acc. to the hydraulic diagrams in Chapter 3 “Hydraulic
diagrams”.
PHP series devices can be used in plants with max.
temperature of 70 °C at the connection point. If the max.
temperature at the connection point exceeds 70 °C,
cooling vessels must be installed.
The implementation into the system return must be done
at a position where no external pressure can occur.
External pressures could affect the trouble-free operation
of the pressure maintenance device.
2.2 Degassing module PHP EMAE-1,
makeup module PHP EMCF-1 V
(Model EMCF-1 V included when
break tank fitted).
PHP series devices factory provided are delivered without
degassing module EMAE-1. The mounting of these modules
is done acc. to the assembly instruction which is delivered
with the module.

13
Commissioning procedure:
STEP 1
Determine the upper working pressure. This upper working
pressure is also the set pressure of the overflow valve.
STEP 2
Shut all connections from/to system return (expansion
overflow pipe, expansion pressure pipe, makeup water).
CAUTION: Do NOT shut suction pipe and overflow pipe
at PHP series.
STEP 3
Fill and ventilate the system to the upper working pressure
as determined in Step 1.
STEP 4
Check the correctness of all hydraulic and electric
connections, especially the expansion pipe.
NOTE
Steps 1-3 must be completed on site in preparation for
the commissioning.
Figure 3: determination of the upper and lower working pressure
10m wc (meter water
column) ~ 1 bar
NOTE
Commissioning by an authorized partner and training
of the operating personnel is required.
STEP 5
Open the makeup water connection to EMCF-1 V
makeup module and set the pressure reducing valve
to 1,5 bar - max. 2,0 bar.
Loosen the screw (1) at the pressure reducing valve and
set the scale to 1,5 bar - max. 2,0 bar.
To fix the setting, the screw must be tightened again.
STEP 6
Switch on power supply and check if the red control lamp
beside the key ”0” glows. If not, deactivate the device by
pressing the key ”0” and following confirmation by pressing
the key ”F1” (red control lamp beside the key ”0” must glow).
5.1

STEP 7
Fill and ventilate the pressure maintenance pump(s) and
the piping.
• The Shut off devices at the intake side of the pump(s)
must be opened completely and the regulating valve
at the pumps outlet side must be closed completely.
• Open the ventilating valve at the pump(s).
• If an EMCF-1 V makeup module is installed, go to manual
mode (user level 3), see instruction manual PHP A-1,
chapter 5.7, ”user level 3”.
• Switch on the output ”makeup valve Y1” (”output: on”)
and fill the vessel until a continuous water jet leaks from
the ventilation valve at the pressure maintenance pump.
After this set the output ”makeup valve Y1” to automatic
mode (”output: auto”).
PHP A-4, 6, 8 & 9 Instruction Manual / Commissioning PHP A-4, 6, 8 & 9
14
Figure 5: ventilation of the pressure maintenance pump(s)
• If a EMCF-1 V makeup module is not installed, you have
to fill the vessel (e.g. via the emptying at the connection
of the overflow pipe - see figure 5, detail B) until
a continuous water jet leaks from the ventilation valve
(detail A) at the pressure maintenance pump.
• To ensure a complete ventilation of the pump start and
stop the pump in manual mode (”output: Test”, operate
with ”F1”) several times.
• In the course of these pump starts you have to check the
direction of the rotation of the pump motor. The fan wheel
must rotate according to the sticker on top of the motor
cover. You can see the fan wheel through the holes of the
pump cover.
• If the fan wheel doesn‘t rotate in the right direction, you
have to change 2 of the 3 phases to weaken the rotating
field and the direction of the rotation.
• Close the ventilation valve of the pressure maintenance pump.
• At devices with 2 pressure maintenance pumps (system
Duo and Maxi) repeat the above steps for the second
pump (pump 1 = left side, pump 2 = right side).

NOTE
Take care to select the right operating mode of
the degassing function. If the selection happened
incorrectly degassing can‘t work correctly.

PHP A-4, 6, 8 & 9 Instruction Manual / Commissioning PHP A-4, 6, 8 & 9
STEP 9
Enable the device by pressing the key “I” in main display and
confirm it by pressing the key ”F1” (Yes) (green control lamp
beside the key „I” must glow.)
STEP 10
Adjust the pressure maintenance pump(s)
Due to the necessary working pressure the pump(s) must
be adjusted on the output side. This adjustment must be
done because the delivery rate of the pump(s) (acc. to their
characteristic curve) rises at low pressures.
A hint for a necessary adjustment could be:
After pump stop the overflow valve doesn‘t close completely
before approx. 0,5 bar under the upper working pressure.
The setting (1) of the regulating valve(s) must be notated at
the plant- resp. commissioning record.
setting regulating valve pump 1:
setting regulating valve pump 2:
STEP 11
Set the working pressure.
• Open the shut off devices from/to system return
(expansion pipe, makeup). If a EMAE-1 degassing module
is installed, the ball valve at its intake side must be closed.
Due to the size of the system the setting of the working
pressure can take up a lot of time because the pressure
has to extend into the entire connected system to be
stable for the setting.
• Go to user level 3 (see step 9).
NOTE
The adjustment of the pressure maintenance pump(s)
must be done before the setting of the working
pressure. After this neither the working pressure nor
the adjustment must be changed. If the adjustment
was done subsequently the working pressure must
be set anew.
• Select “settings” “pressure maintenance” “working
pressure”
• The display shows the current settings (complies with the
last set working pressure, e.g. default value ex factory)
CAUTION: Independent to the displayed values the
working pressure must be set again in the course of
commissioning.
• Press the key “F1” (change) to start the pump.
• Set the overflow valve to the upper working pressure
(determined in step 1), the current pressure is shown at
the display. The setting of the setpoint at the overflow
valve via
(a) black hand wheel,
(b) hexagonal nut at the spring cap
(c) set point adjustment
(depends on the used type of the overflow valve).
• Do not confirm the set upper working pressure until the
desired pressure is not stable for a few minutes. (confirm
with “F1” (apply)
• Enter the hysteresis (default value: 0,5 bar). Difference
between the set upper working pressure (set at the
overflow valve) and the start-up pressure of the pump
(=lower working pressure).
• In devices with 2 overflow valves (system Twin), both
valves must be set one by one. One of these valves must
be shut off, at the other one the upper working pressure
can be set. Then the set valve must be shut off and the
other one can be set - repeat the above steps (set both
valves to the same pressure.)
NOTE
In Twin devices only one overflow valve must be in
operation, the other one must be shut off at its intake
side. If both valves are in operation at the same time,
the control behaviour can be influenced negatively
(e.g. too big hysteresis). Therefore this must be avoided.

PHP A-4, 6, 8 & 9 Instruction Manual / Commissioning PHP A-4, 6, 8 & 9
STEP 12
If a EMCF-1 V makeup module is installed, the operating
mode must be selected. The operating mode is depending
on several criteria such as size of the system, age of the
system, possible known leakage and so on.
If there are known and regular leakages (e.g. a known
makeup amount within a known period) we recommend
to use the operating mode ”time-controlled”.
For a description of the different operating modes see
instruction manual PHP, chapter 5.7 - “user level 3”.
STEP 13
If a EMAE-1 degassing module is installed, the operating
mode ”degassing module” must be selected. If the selection
happened incorrectly, degassing can‘t work correctly.
Adjustment of the degassing module:
• Shut off the regulating valve and the ball valve at the
degassing module.
• Go to manual mode (user level 3) (see instruction manual
PHP A-1, chapter 5.7 “user level 3”) and switch on the
output ”degassing valve” (”output: on”)
• Wait until the motor valve opened completely (ca. 35 sec.;
the scale resp., the red axis at the electric actuator must
not rotate anymore).
• Open the ball valve at the intake side.
• Open the regulating valve slowly until you hear a flow
(ca. 1/4 turn). The plant pressure decreases, the pressure
maintenance pump starts.
• Look for the plant pressure shown at the display.
• The regulating valve is set correctly, if pump 1 is able to
increase the plant pressure and stops. If the pump can‘t
increase the plant pressure resp. the second pump starts,
the regulating valve is set incorrectly (opened too much).
• After this, the output ”degassing valve” must be set
to ”Auto” again.
• The setting (1) of the regulating valve must be notated
at the plant- resp. commissioning record.
Setting regulating valve EMAE-1:_______________________
STEP 14
The device is now ready for operation.
All shut off devices from/to system return must be secured
against unintended closing (e.g. by dismantling the
handle,...)
Further settings (e.g. water treatment, operating modes etc.)
must be done in menu ”settings” (see instruction manual
PHP A-1).
