Installation manual

GENERAL WARNINGS:

he solar system should never be left with water in and not fully commissioned. If

commissioning can not take place, the unit should be left with no water content or the

collectors covered.

Both circuits contain unvented systems. Please ensure all relevant relief valves and

associated expansion equipment are fitted. This includes any equipment not supplied by

Andrews Water Heaters. The installation should only be carried out by a competent person

as per the Building Regulations.

Solar collectors are both high temperature water and steam generators. Therefore high

pressures and temperatures can be generated. The collectors and associated equipment

have been designed for these conditions. However the collectors should be treated with

precautions associated with high temperature/pressure systems.

Full Health and Safety regulations should be followed for all aspects of installation.

IMPORTANT INSTALLATIONS NOTES

1. ENSURE THE INSTALLATION IS CARRIED OUT AS PER THE APPROPRIATE

SYSTEM SCHEMATIC AND THAT ALL EQUIPMENT IS INCLUDED AND

INSTALLED CORRECTLY.

2. COLLECTORS ARE INSTALLED AT THEIR OPTIMUM ORIENTATION AND

ANGLE TO MAXIMISE SOLAR CONTRIBUTION. SEE TECHNICAL

SPECIFICATION SECTION.

3. ENSURE PIPE-WORK IS AN APPROPRIATE SIZE FOR FLOW RATES.

4. FOR COPPER PIPE-WORK ONLY BRAZED OR COMPRESSION/SCREWED

CONNECTIONS SHOULD BE USED, APPROPRIATE FOR THE HIGH

TEMPERATURES >215°C.

5. APPROPRIATE EXPANSION VESSELS AND RELIEF VALVES SHOULD BE

INSTALLED ON BOTH SOLAR AND DOMESTIC HOT WATER SIDES OF THE

SYSTEM.

6. THE SOLAR SYSTEM SHOULD ONLY BE FILLED USING THE SUPPLIED

GLYCOL/WATER MIX. IT IS RECOMMENDED THAT THIS IS USED FOR TEST

FILLS DUE TO THE DIFFICULTIES IN DRAINING DOWN THE ENTIRE WATER

CONTENT IN THE COLLECTORS.

7. THE ANDREWS SOLARflo SYSTEM REQUIRES 230V, 4AMP (OTHER

SYSTEMS MAY REQUIRE MORE). THE POWER SUPPLY TO THE

CONTROLLER MUST BE ABLE TO BE ISOLATED CLOSE TO THE UNIT. A

SEPERATE 230V PLUG SOCKET MUST ALSO BE AVAILABLE FOR

COMMISSIONING.
