1.3.5 IDENTIFYING MiniPack “Standard/Basic” -B or “Enhanced” -E UNITS
1.3.5.1 The control panel fascia will state the “Model” and the “Serial Number” e.g.
WN12345 or SN0654321
. In
addition to this: -
1.3.5.2 A “standard/basic” –B pressurisation unit controller has a 2 digit
display: -

a 2 line by 20 or 24 character display: -
1.3.6 ELECTRICAL
READ GENERAL SAFETY INFORMATION 0.0, WARNINGS 0.1 and CAUTIONS 0.2, 0.3 & 0.4
1.3.6.1 All wiring must comply with the latest addition of local wiring Regulations.
1.3.6.2
Wear anti-static wrist strap at all times
to avoid static discharge causing problems with the built in
electronic program.
1.3.6.3 Connect incoming electrical mains supply to isolating switch & Earth stud in panel (see fig.1.6). Ensure
voltages and frequency indicated on the motor nameplates and wiring diagrams correspond with supply
mains data and that the supply fuse ratings are correct for the total current rating of the equipment.
Refer to wiring diagram supplied with the unit or AquaTech-Pressmain.
1.3.6.4 For standard controller units: Connect boiler/chiller to plug/socket terminal on pcb card in series with the
boiler/chiller control circuits so that in the event of a fault condition occurring the boiler/chillers shut
down and remain inoperative until the fault condition is rectified. (See fig 1.6b). Boiler relay is energised
for normal condition and releases to a high or low-pressure alarm fault condition.
1.3.6.5 For Enhanced controller units: Make any BMS connections required to terminals A-Z on Interface pcb
card inside control panel. Connect boiler/chiller terminals nos. X,Y,Z on interface card in series with the
boiler/chiller control circuits so that in the event of a fault condition occurring the boiler/chillers shut
down and remain inoperative until the fault condition is rectified. (See fig 1.7). Boiler relay is energised for
normal condition and releases to a high or low-pressure alarm fault condition.
1.3.6.5 Complete any required earth bonding.
Note: To aid access to the controls, switch off the power, remove outer cover, undo the two control shelf retaining
screws (Fig 1.5a), the control shelf will now hinge forward (Fig 1.5b). When complete reverse the above sequence
ensuring the two control shelf retaining screws are refitted correctly to ensure the keypad & display line up with the
holes in the outer cover. DO NOT trap any wires!
