F. WATER PRESSURE TEST
• It is IMPORTANT that a pressure check is carried out.
• Low and high pressure can result in either damage to, or failure of the unit.
• If daytime static water pressure* exceeds 3.5 bar (50psi) a 5 bar pressure limiter
should be fitted. *50psi daytime pressure can reach nearly 100psi at night!
• Minimum dynamic pressure must exceed 1.5 bar.
• If in any doubt please call us on
