8. First start
CTC EcoZenith i360 can be installed and started before the ground source
or air-to-water heat pump is put into operation. In order to use the product
as electric boiler before a heat pump is installed, the installation engineer
must connect the pipes to and from the heat pump (see the pipe installation
section). The product can also be started without a room sensor being fitted
as the curve which has been set then regulates the heating. The sensor can,
however, always be fitted for the alarm LED function.
Before fi rst start
1. Check that the product and system are full of water and have been
bled. (CTC EcoZenith i360 is bled manually with a safety valve on the
top cover of the product, activate the automatic bleeder as well for the
first three months).
2. For installation with a heat pump, follow the instructions in the heat
pump manual.
3. Check that all connections are tight.
4. Check that the sensor and radiator pump are connected to the power
source. Check that the connections behind the insulation cap remains
tight. Remove both insulation caps by pulling carefully on the points
marked.
5. The backup heating thermostat is factory-set to OFF (off position
when it is turned anticlockwise as far as it will go, at which point
the screwdriver slot is vertical). Recommended mode is = Frost
protection setting, approx. +7 °C. The backup heating thermostat is in
the electrical switchboard behind the front panel. See the image on the
right for what the antifreeze setting looks like.
At the end of the installation, check the connections of any current
sensors. At this point it is important that you have switched off any
major electricity-consuming appliances in the house. Also make sure
that the backup heating thermostat is turned off.
NB: The product has an automatic bleeding sequence for the DHW
system, which runs in the background. The sequence takes approx.
15 minutes and does not affect other functions.
