Safety information, installation and maintenance

For full details see the Installation and Maintenance Instructions

supplied with the product, which gives full wiring, commissioning

and operating instructions.

Warning:

This product contains materials including PTFE which can give

off toxic fumes if exposed to excessive heat.

Installation note:

Do not install the probe outdoors without additional weather

protection.

300 mm and 500 mm probes can be installed vertically or horizontally.

CAUTION: 1000 mm probes must be installed vertically only.

The probe must be installed in a position where it can sense the

conductivity of the boiler water, away from the feedwater inlet if

possible.

The CP32 contains no user serviceable components, and periodic

cleaning is all that is required. Any attempt to dismantle the probe

will result in permanent damage.

Spare parts

There are no available spare parts for this product.

How to specify

TDS conductivity probes shall be Spirax Sarco type CP32 with

nickel alloy sensor tips and built-in temperature sensor. They must

incorporate a patented facility to check the sensor tips for scaling.

When used in conjunction with an appropriate Spirax Sarco

controller, they must also be able to automatically initiate a patented

probe cleaning feature, which, if unable to clean the probe, will

activate a warning on the controllers display panel and/or a remote

alarm. The system must also be able to automatically compensate

for any polarisation effects at the sensors. They must be suitable

for boiler pressures up to 32 bar g and a maximum working

temperature of 239°C. They must be available in 300 mm, 500 mm

and 1000 mm lengths, and have a " BSPT or 1⁄2" NPT boiler

connection.
