Installation Details - Marco ECOBOILER T20-3 Instructions

S AFETY:
 This appliance must be earthed. If the moulded plug supplied is not used then ensure that
the green/yellow cable is connected to a suitable earth.
 Risk of flooding. The hose supplied with this unit is non-toxic food quality tested to 190psi.
However, a hose is not a permanent connection. It is, therefore, advisable to switch off
boiler and close the stopcock valve when boiler is not in use, e.g. overnight, weekends etc.
 Risk of scalding. Beware of accidentally operating the water drawoff tap or push button
especially when cleaning the front of the boiler.
 The utmost care has been taken in the manufacture and testing of this unit. Failure to
install, maintain and / or operate this boiler according to the manufacturer's instructions
may result in conditions that can cause injury or damage to property. If in any doubt about
the serviceability of the boiler always contact the manufacturer or your own supplier for
advice.

INSTALLATION DETAILS:

Electrical installation:
 Electrical specification:
o (T20-3) 2.8kW-230V - A moulded 13A plug is factory fitted. A suitable 13A outlet is all
that is required.
o (T20-6, T30) 5.6kW/230V - This needs to be connected to a 30A isolator outlet. A
qualified electrician should do this.
Plumbing installation procedure:
 Mains water pressure required (limits): 5-50psi (35-345kPa)
 Fit a stop Valve on a cold water line and attach a 3/4" BSP male fitting,
 (e.g. 3/4" x 1/2" 311 or washing machine type stop valve).
 Connect straight tailpiece of the hose to the stop valve fitting. Make sure that the pre-attached
sealing washer is fitted.
 Turn on the water to flush any impurities, dust etc from the inlet hose and water pipe. Allow
several gallons through.
 Connect right-angled tailpiece of the hose to the inlet valve of the boiler (again 3/4" BSP).
Make sure the sealing washer is fitted here also.
 Turn on water and check for leaks.
Operating boiler for the first time:
 Check that all installation procedures have been carried out.
 Ensure water valve is on.
 Switch the machine on by pressing the power button on the front of the machine marked
'Power'. Refer to Figure 1.
 The "power on" light will glow green and the machine will fill to a safe level, above the
elements, before heating.
 The "Ready/Status" light will cycle two red flashes while the machine is filling to the safe level.
 After this amount of water has heated to about 96ºC the boiler will draw more water in until the
temperature drops by 1 or 2 degrees. The boiler will then heat again. This heat fill cycle
continues until the boiler is full.
 Whilst the machine is above the safe level and filling, the "Ready/Status" light will remain
blank.
 The "Ready/Status" light will glow green when the machine up to normal operating
temperature.
 The boiler is now ready for use.
