The Bosch AQOK kit itself does not have operational controls. Its function is to provide a protective environment for the AquaStar 2700ES water heater, allowing it to operate safely outdoors. Once the kit is installed and the water heater is properly connected and started according to its own manual, the water heater will function as intended within its protective enclosure.
Ensure the enclosure doors or access panels are securely closed after any maintenance or inspection to maintain weather protection.
7. Maintenance
Regular maintenance of the AQOK kit ensures its longevity and continued protection for your water heater.
- Annual Inspection: Annually inspect the enclosure for any signs of wear, corrosion, or damage. Check seals around doors and utility penetrations for integrity.
- Cleaning: Keep the exterior of the enclosure clean from debris, leaves, and dirt to prevent blockage of vents and maintain appearance.
- Fasteners: Periodically check all mounting fasteners and enclosure assembly screws to ensure they remain tight.
- Pest Control: Ensure no pests (insects, rodents) have made nests inside the enclosure, which could obstruct ventilation or damage components.
