HANDLING REFRIGERANT

WHAT TO DO IF REFRIGERANT LEAKS

If refrigerant leaks and touches the skin, it can cause frostbite.

▶ In case of a refrigerant leak, never touch any part of the ground source

heat pump.

▶ Avoid skin or eye contact with refrigerant.

▶ Seek medical attention if you get refrigerant on your skin or in your

eyes.

▶ If the refrigerant leaks please contact your installer immediately.

2BENCHMARK

Benchmark places responsibilities on both manufacturers and

installers. The purpose is to ensure that customers are provided with the

correct equipment for their needs, that it is installed, commissioned and

serviced in accordance with the manufacturer's instructions by

competent persons and that it meets the requirements of the

appropriate Building Regulations. The Benchmark Checklist can be used

to demonstrate compliance with Building Regulations and should be

provided to the customer for future reference.

Installers are required to carry out installation, commissioning and

servicing work in accordance with the Benchmark Code of Practice

which is available from the Heating and Hotwater Industry Council who

manage and promote the scheme. Visit www.centralheating.co.uk for

more information.

triangle printed against a grey background.

Keywords at the start of a warning indicate the type and

seriousness of the ensuing risk if measures to prevent

the risk are not taken.
