GENERAL

These instructions are intended for the installer of this Level/Temperature Monitoring or control unit. Please

follow them carefully. Failure to install the equipment as recommended could invalidate the warranty provided

by AquaTech‐Pressmain to the buyer.

1.2

ADDITIONAL WARNINGS AND CAUTIONS

1.2.1

READ GENERAL SAFETY INFORMATION 0.0, WARNINGS 0.1 and CAUTIONS 0.2, 0.3 & 0.4

1.2.2

Installation of this equipment assumes prior correct and safe installation of the tank(s) and that you

are aware of all safety practices and hazards involved with the tank(s).

1.2.3

When installing sensors if you are unsure of any aspect you must seek the advice of the tank

manufacturer before commencing any modifications/alterations to the tank in order not to

compromise its performance.

1.2.4

Level sensors must not be subjected to more than 1.5 times the rating of the sensor; otherwise

irreversible damage may be done.

1.2.5

Temperature sensors must remain submerged at all times.

1.2.6

When chlorination of a tank is carried out, ensure that any residual chlorine is removed by thorough

flushing as detailed in the HSE approved code of practice L8, to avoid damaging the submersible

sensors. The normal level of chlorination is up to 2 parts per million (ppm), but shock dosing for

sterilization purposes, at 25‐50 ppm for 24‐48 hours is acceptable as long as all chlorine is removed

once the process is complete.

PROCEDURE

1.3.1 SENSORS

Sensors are available in standard form for attaching externally to the side of the tank, or submersible

form for suspending in the tank contents.

1.3.1.1 Standard Sensors ‐ externally mounted

Standard Level Sensor for monitoring liquid level:

A standard Level Sensor is fitted to the side of the tank via an isolating valve and 1/4" BSP parallel

female connection and wired to wall mounted connection box, or direct to the monitoring unit, within

5m (see Fig 1a.).

The depth of water displayed is that measured from the lowest point of the Level sensor.

Position the sensor at the minimum liquid level.

Standard Temperature Sensor:

A standard Temperature Sensor is fitted to the side of the tank in a 1/2" BSP parallel fitting, or

optionally into a sealed pocket (see Fig 1a.) and wired to wall mounted connection box or direct to the

monitoring unit, within 5m (see Fig 1a.). Position the Temperature sensor so that it is submerged at all

times.

1.3.1.2 Submersible Sensors

Submersible sensors are suspended in the liquid from a connection box on top of the tank as shown in

Fig 1b. They are restrained by a weighted guide wire or by a stilling tube to avoid turbulence damaging

the sensor.

Drilling the tank lid to take the flange (where supplied) see Fig 2

Select a suitable area of the tank, away from turbulence, for the sensors to be fitted.

Cut 80mm diameter hole taking care to prevent any swarf falling into the tank. Equally spaced about

this hole, mark 4 holes as shown in Fig 2, drill and tap M5 or fit clench nuts if required.
