Common Installation Faults
For optimum performance, this unit must be correctly sized to match the heat loss requirements of the space it is required to
heat, and the heating system must be correctly designed to provide adequate flow of hot water to the unit (refer to section
2). If the recommendations in section 2 are not followed, problems may arise as detailed below.
Problem | Possible Causes | |
Poor heating performance | Unit incorrectly sized for heat loss of room | |
(Heater model only) | ||
| ||
| Boiler thermostat set too low | |
Heating Mode | Lack of flow to fan convector - | |
(Heater model only) | ||
| ||
poor heating | Pump set on low setting | |
performance and/or | Isolating valves not fully open | |
unit cycles on | ||
water sensor | System incorrectly balanced with unit starved of hot water flow | |
| ||
| Pipe sizing to unit too small |

13.0 Maintenance
Before undertaking any maintenance activity isolate the electrical supply.
Maintenance should be restricted to occasional removal of dust and lint around the unit. The outer surface may be wiped over
with warm water and mild detergent taking care to avoid water entering the grille areas.
