The air conditioning plant and control system contains no user serviceable parts. Installation, service and maintenance of these
components should be carried out by a suitably qualified technician.
4. Manufacturers Recommendations
The following information is a guide to efficient use of your new Sygnal system. Following these tips will
contribute to the long life of the unit and could save you money.
4.1 Essential Operating Guidelines
The Filters must be in place to run the unit. Never operate the unit without the filters.
4.2 Tips for saving energy
For optimum unit efficiency, cost benefit and comfort levels we recommend setting the temperature
between 20°C and 24°C for both heating and cooling.
By covering windows with blinds or curtains you increase the cooling (heating) efficiency.
Dirty air filters cause inefficient operation and reduce unit efficiency. Clean monthly by either vacuum
or hand wash in mild detergent.
Turn the system off at the circuit breaker (located near the outdoor unit) prior to going on holidays to
ensure timer programs don’t cause unnecessary operation.
4.3 Power Failures
Your new Sygnal system has a memory function that automatically stores settings in the event of a power
failure. After power is restored the unit will automatically re-start with the same settings active before the
power failure and in accordance with any timer setting. This feature covers all operating settings.
5. Maintenance
Regular maintenance will ensure your Sygnal system operates at maximum efficiency.
5.1 Return Air filter cleaning
Cleaning the filter in the return air grille is recommended every month. Filters may be cleaned by either
vacuum or hand wash in mild detergent. Never operate the air conditioner without the filter. Ensure the filter
is in good condition, if not contact your installer for a replacement filter (a charge will apply)
5.2 Outdoor Unit
Do not place any object in front of the condenser. Keep free of grass, leaves and any other form of debris. This
will allow for proper air flow and ensure unit efficiency.
5.3 Vents & Return Air Grill
Regular cleaning of the return air grill and air vents is recommended. This will prevent build-up of dust and
dirt.
5.4 Controller
Clean the wall control with a dry cloth. Do not use a spray detergent or water.
The control circuits for the indoor and outdoor units carry voltages > 240 VAC which can cause serious injury or death.
