10.3.3 EXPANSION VESSEL SIZING
The following information is based on an inlet pressure of 3.5 bar. If a different inlet pressure is to be used, please
consult
BS6700.
V V = S V * e
0.45
Where:
V V
= Vessel Volume
S V = System Volume
e = Coefficient of Expansion (See Table 10.1)

TABLE 11.1 ELECTRICAL SUPPLY REQUIREMENTS
WARNING: THIS APPLIANCE MUST BE EARTHED
A suitably competent person MUST check wiring. Normal supply required is 230 volts AC, single phase,
50 Hz. An isolator with a contact separation of at least 3mm in all poles should be sited close to the
equipment and must only serve that equipment. The double pole switch must be readily accessible under
all conditions.
11.1 EXTERNAL CONTROLS
The Lochinvar EcoShield is compatible with the following control and safety systems:
 Gas pressure switch (e.g. gas booster under pressure/over pressure safety switch)
 Auxiliary safety system proving switch (e.g. fan dilution system proving switch)
In addition to this, the Lochinvar EcoShield can give the following signals:
 Volt-free “burner on” (runtime) signal
 Volt-free “lock-out” (alarm) signal

24VAC auxiliary device enable signal (e.g. to start fan dilution system)
11.1.1 REMOTE ENABLING
When remote control of an EcoShield water heater is required and controlled using a Building Management
System (B.M.S.) the factory fitted wiring between the low-voltage connection strip and the tank temperature sensor
