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
5. Manufacturers Recommendations
Regular maintenance will ensure your SAI HVAC 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 Controllers
Clean the wall controllers with a dry cloth. Do not use a spray detergent or water.
IMPORTANT
: Neon signage will interfere with the operation of SAI HVAC controllers. Do not have neon lights
near SAI HVAC Navigators or Room controllers as the Electromagnetic field (EMF) will disrupt the operation of
the controllers.
The control circuits for the indoor and outdoor units carry voltages > 240 VAC which can cause serious injury or
death.
