ELECTRICAL REQUIREMENTS
An individual wiring diagram for the boiler is located with the control panel. When referring to the
electrical specification of the boiler, the wiring diagram number should be quoted.
The power ratings and requirements are given in
Appendix A - TI-115-EP-18-72 Dimensions &
Specification
. The boiler contains all necessary electrical protection.
An electrical isolator should be fitted on a wall as close as possible to the boiler.
It is recommended that the electrical supply to the boiler is located through the rear of the unit
below the boiler blowdown valve as shown in
Figure. 3
(ensure the cable is not rubbing against
areas capable of damaging it). The cable should be routed from this point and secured in a gland
nut (not supplied) fitted in the bulkhead at the base of the electrical panel.
Care should be taken to ensure the supply cable is the correct size and installed in accordance
with local regulations.
WARNING
The control circuit live light is derived from a single phase.
It is possible that with the control phase down or a defective bulb the other phase could be live.
Always isolate the supply before investigating any fault.
!
The quality of the water used in the boiler will affect the life and performance of the boiler and
elements.
Feedwater contains solids and dissolved gases, these may promote encrustations of scale;
foaming, priming, surging; corrosion and pitting; or caustic embrittlement. To prevent this
happening it is strongly recommended that a reputable water treatment concern is consulted prior
to commissioning the boiler.
Note: See Appendix A - TI-139-Recommended Water Conditions.
Note:
Elements damaged due to adverse water conditions cannot be replaced under guarantee. Should chemical
dosage of the boiler feedwater be required a connection point and a water sampling point are provided at the rear
of the boiler.
