Safety Information, Installation and Maintenance

For full details see the Installation and Maintenance Instructions (IM-P144-02) supplied with the product.

Installation note: The CA14 must be installed with the direction of flow as indicated on the body, and with the float arm in a horizontal plane so that it rises and falls vertically.

Disposal

If a product which contains a Viton component has been subjected to a temperature approaching 315 °C or higher, then it may have decomposed and formed hydrofluoric acid. Avoid skin contact and inhalation of any fumes as the acid will cause deep skin burns and damage to the respiratory system. Viton must be disposed of in a recognised manner as stated in the Installation and Maintenance Instructions. No other ecological hazard is anticipated with the disposal of this product providing due care is taken.

How to Order

Example: 1 off Spirax Sarco ½" CA14 having screwed BSP T Rp (ISO 7-1) connections with SG iron body and cover.
