HRS Hevac Ltd AquaModule AMB

Installation, Operating & Instruction Manual

1 General information

HRS Hevac AquaModule AMB is a compact tap water system product including a brazed heat exchanger,

motorised control valve and managed primary and secondary pumps, as per versions.

It is equipped with a control box including a dedicated PCB and communicant temperature controller.

Piping is made of specially designed brass parts sealed by flat gaskets for easy maintenance.

AMB has been tested hydraulically and electrically at the factory.

The AMB must be connected to a primary heating source, like a boiler or a heat exchanger. The secondary

side is connected to cold water inlet and to domestic hot water network, see flowcharts for more details.

The tap water module is designed for indoor installation, for example in a plant room. The ambient

temperature in the room must be min 0°C and max 40°C, max humidity 85% without condensation.

Pump Type: S-Single Primary

D-Double Primary

SS -Single Primary / Single Secondary

DS-Double Primary / Single Secondary

Available pressure on primary side : at least 5 kPa on all models. This pressure results from the difference

between the primary pump head and all the pressure drops (heat exchanger, control valve and piping).

If pressure drop between AMB and heating source is higher than 5 kPa, use either a transfer pump of the

same flow rate as primary pump or a mixing bottle. Please refer to flowcharts in this manual.

AquaModule AMB S & D AquaModule AMB SS & DS

The primary water enters the 3-port modulating valve (1) and leaves through the fitting (2).

Cold water enters at bottom connection (3) and leaves at the required temperature at top connection (4).

The secondary circuit should be equipped with a recirculation or a charging pump,

Modules suitable for 230V 1 phase / 50 Hz + Earth,

Make sure power supply in the field corresponds to the above voltage,

A fuse protection or MCB should be provided on site.

Relays: Volt Free Contacts (VFCs), 2 Amps max, each under 230 V.

Installation, Operating & Instruction Manual

3Installation

The installation work must be carried out by an authorized installation contractor.

The temperature and the pressure of the water are very high. Only qualified technicians

are allowed to work with the Aqua0RGXOH$0%. Incorrect operation may cause serious

personal injury and result in damage to the building.

Minimum pressure/temperature on primary side: 1.0 bar/ 2°C, 1.5 bar / 110°C

Maximum pressure/temperature on primary side :10 bar /110°C

Maximum pressure on secondary side: 10 bar/ 100°C

3.1 Unpacking/Preparation/Mounting

xRinse the pipes, before connecting them to the tap water module.

Pipe works may contain solid particles that could block or prevent the modulating valve to

operate correctly.

xPipe the primary and the secondary of the module.

xFill-up both sides progressively with water.

xPurge air at high parts.

xPurge all the pump bodies.

xSwitch the power on.

xCheck controller setting and enable the required functions.

3.2 Commissioning

Before installation this manual must be read.

The controller has been set at the factory. If any function needs tuning, values can be changed with

reference to this manual for parameter setting. Initially, the commissioning process should be

carried out with the factory settings.
