A divertor valve (supplied loose) is included with East/West Electromax Solar models.
The Electromax Solar, divertor valve and the solar collectors are connected as follows:
• The Electromax Solar return is connected to the divertor valve connection marked AB.
• Divertor valve connection marked A is connected to the East collector return.
• Divertor valve connection marked B is connected to the West collector return.
• The Electromax Solar flow is connected to both the East and West collector flows.
Connection to the divertor valve is made be 22mm compression fittings. 22mm copper tube
or stainless steel flexible tube may be used. Adaptors to connect 22mm compression fittings
to stainless steel flexible tube are available (accessory code 5122238).
The solar expansion vessel should be connected to the Electromax solar return before the
