10.0 Determining the Cold Fill Pressure
The Cold Fill Pressure is critical to the correct operation of any Pressurisation Unit and associated system. This pressure
needs to be calculated from the Static Pressure of the system (measured height in metres from the base of Pressurisation Unit
to the top of the highest part of the heating system, divided by 10 to convert to bar pressure), and an allowance for venting and
vapour pressure.
Therefore the Cold Fill Pressure, for a system with a maximum operating temperature up to 90ºC, can be calculated as per
the example below:
Static Pressure
0.8 bar
(Height of 8.0metres, divided by10)
Venting Allowance
0.3 bar
(Allowance from Tablebelow)
Vapour Pressure
0.0 bar

11.0 First Filling
Before attempting to FILL THE SYSTEM, Section 11.1, please ensure that the following checks have been completed;
1) Check the Heating / Chilled Water system expansion vessel air charge. This vessel charge should be equal to the
calculated Cold Fill Pressure (+/- 0.2 bar) when the vessel is empty of water. See Section 10.0.
2) The Quarter Turn Isolation Valve on the underside of the Break Tank is in the CLOSEDposition.
3) The Quarter Turn Isolation Valve on the Water Outlet (on the end of the flexible pipe) is in the CLOSED position.
4) The Mains Water Supply has been connected, vented, and the appliance Break Tank has been filled with clean
water. Any foreign bodies/debris are to be removed before the appliance is set to work.
5) The Electrical Supply has been connected and tested for correct polarity.
Power should not be applied to the appliance at thisstage.
6) The Heating / Chilled Water system has been fully flooded and vented as detailed in Section 11.1below.
On completion of the above checks the unit is ready to be Set Up to the system requirements, and the following procedure shall
be followed.
To Prevent duplication of setting activities, it is advisable to undertake the testing/setting of the High and Low Pressure
Alarm Switches prior to setting the Cold Fill Pressure. To Prevent potential over pressurizing or loss of water treatment, the
following test shall be undertaken with the outlet value of the appliance CLOSED.

11.1
Filling the System
Before attempting to FILL THE SYSTEM, please ensure that the procedure in Section 11.0 has been fully completed.
The Microprocessor of the Minifill (Electronic) has a FILL function, which utilizes the internal pumps to introduce water into the
Heating / Chilled Water System. This function negates the need for a separate filling method such as a Fill Loop, Fluid
Category 3 (C-3) In-House; or a Reduced Pressure Zone (RPZ) Valve, Fluid Category 4 (C-4) Other Than In-House.
The FILL function will introduce water into the Heating / Chilled water system for up to 6 hours, or until the Cold Fill Pressure
of 1.8bar (Factory Default Setting) has been achieved.
To Fill the Heating / Chilled water System, the following procedure shall be followed;
1) Ensure that the Cold Water Supply has been cleaned of any air or installation debris. Turn ON the Mains Cold
Water Supply to the appliance. Remove any debris from the Water Tank, and check the Ball Float Valve for correct
operation.
2) Open the Quarter Turn Isolation Valve on the underside of the BreakTank.
3) Vent The Pump. Located on the top of the center pipe connection of the pump assembly, is a vent valve. Undo
this vent valve with a vent Key and release any air. When all the air has been released, securely close the vent
valve.
4) Ensure that all drain valves, bleed points, etc, on the Heating / Chilled Water System are FULLY CLOSED, andthat
there are not any open ended pipes.
5) Open the Quarter Turn Isolation Valve on the Water Outlet (on the end of the flexiblepipe).
6) To activate the FILL function, the MAINTENANCE MENU of the Microprocessor must be accessed, this can be
done by Pressing & Holding the UP program button, and turning ON the POWER SUPPLY to theunit.
After a few seconds the LCD will display AUTO / Fault Code.
Using the DOWN program button, scroll through the settings until the word FILL appear on the LCD display. Press
the ENTER button to activate the FILL function. (The unit may operate upon power application if the sensed
pressure is below the set point of the unit. The FILL function should be used to prevent incorrect alarm activation.)
7) The PUMP will now operate and introduce water into the Heating / Chilled Water System.
8) Check the operation of the Ball Float Valve, and that the Main Cold Water Supply is suitably replenishing the water
into the Water Tank.
If the Mains Cold Water Supply cannot replenish the water sufficiently, then the LOW WATER SWITCH fitted to the
Water Tank will fall to OPEN, and the PUMP will turnOFF.
When the water level has risen the LOW WATER SWITCH will rise to CLOSE, and the PUMP will turn ON again.
9) The PUMP will introduce water into the system until the COLD FILL PRESSURE of 1.8bar (Factory Setting) is
achieved, 6 HOURS has been exceeded, or the LOW WATER SWITCH on the Water Tank falls toOPEN.
10) To terminate the Fill function press ANY BUTTON, and turn OFF the POWER Supply until the unit has been fully
commissioned, as detailed in Section 14.0
PLEASE NOTE:
Great Care should be observed when using the FILL function to ensure that all water joints
etc are sound and leek-free. MHS Boilers cannot be held responsible for any damage that
may result from water leaks. To terminate the FILL function turn OFF the POWERSupply.

11.2
Introduction of Water Treatment
The Mains Cold Water Supply pipework MUST be thoroughly cleaned and flushed to remove debris, flux residues, etc.
before opening the isolation valve and flooding the Pisces Minifill pressurisation manager.
After the Heating / Chilled Water system has been filled, flushed, and cleaned in accordance with BS 7593:1992, the
system will need to be treated with a suitable Water Treatment for the prevention of corrosion, scale formation and micro-
biological growth.
Some Water Treatments are supplied in a concentrated liquid form; it is therefore recommended that the treatment be
added to the water in the Water Tank in small doses. Drain an amount of water from the system (at a position some distance
from the Pisces Minifill pressurisation manager), so that the system pressure drops and the Treated Water in the Water Tank
is introduced to thesystem.
As the Water Tank is replenished with fresh water, gradually add the water treatment (at the correct concentration) until the
appliance turns off. Repeat this process until the entire water treatment chemical has been fully introduced. Let the system
circulate for a minimum of 1 hour, and then undertake a water analysis to ensure the correct dosage level has been obtained.
