Which manual covers your EcoFry model
EcoFry provides separate manuals for its Hop Air Fryer and Spriz Speed Oven series. The installation and operation manuals for the Spriz 12" non-ventless speed oven (model EFE12B) cover that unit, and the same series principles apply to the 16" models (EFE16B and EFE16VB), though the 16" models have different electrical requirements (23.75 A, 30 A breaker).
For the Hop Air Fryers, the operation manual for the EFE35SPVB (3.5 lbs capacity ventless) covers that model, while the EFE475PRO (Hop Air Pro) has its own operation manual.
Installation requirements and clearances
All installation and extraordinary maintenance must be performed by qualified personnel authorized by the manufacturer, in accordance with local codes. The room must be indoors and well ventilated: the Spriz manual asks for +5°C to +35°C with non-condensing humidity, and the Hop Air manuals for +5°C to +45°C (41°F to 113°F) with humidity below 70%. The support surface must be non-flammable, level, and capable of bearing the appliance's full weight.
For Spriz speed ovens, the installation manual (EFE12B) says to maintain at least 50 cm on the sides and 70 cm at the back from other high-temperature equipment, or interpose an insulating wall. The oven is not suitable for recessed installation and must not be placed near flammable materials. For Hop Air Fryers, the EFE35SPVB and EFE475PRO manuals specify minimum clearances: 100 mm from non-combustible walls on the sides and back, and 500 mm from combustible walls on the sides and 700 mm on the back. Always use the supplied feet to ensure proper airflow for cooling electrical components.
Electrical connections must be made by a qualified electrician. The supply voltage must not differ by more than +/-10% from the nameplate value. The EFE475PRO comes with a NEMA LP6-30 plug; other models may require hardwiring according to the connection diagram on the appliance. For Hop Air Fryers that require a water connection (such as the EFE35SPVB), the operation manual specifies cold drinking water with free chlorine less than 0.1 ppm, hardness 60–90 ppm, chloride below 30 ppm, pH above 7.5, silica below 12 ppm, total dissolved solids 50–125 ppm, and pressure between 150 kPa and 200 kPa. A shut-off valve must be installed, and the drain line must have a minimum 5% slope with a siphon to prevent odours. Spriz ovens do not use a water connection; they exhaust fumes through a rear chimney that can be vented outdoors or used with an optional condensation hood.
Daily operation and control panel overview
The Spriz speed ovens (EFE12B operating manual) feature a digital control panel with buttons for ON/OFF, MENU, temperature, time, fan speed, temperature holding, phase/cycle, start/stop, and shortcut programs. You can set a manual cooking temperature between 30°C and 260°C, time, and fan speed (five levels). Preheating can be configured through parameter P20 (modes 0–4). The oven stores up to 99 recipes, each with up to four cooking phases. Special cycles include rapid cooling and a multi-timer for managing different products simultaneously.
The Hop Air Fryer EFE35SPVB uses a 2.4" LCD display with dedicated buttons for temperature, time, fan speed, V-Dry (steam removal), basket rotation, temperature holding, and phases. It can store up to 100 programs with up to four phases (or six with a fixed preheat). Basket rotation modes range from 0 (stationary) to 4/4 (always rotating), with intermediate settings like 1/4 (3 seconds on, 27 off). The EFE475PRO Hop Air Pro has a simpler LED control panel with buttons for temperature (30–300°C preheat, 260°C cooking), time (up to 120 minutes or infinite), drum rotation (0 to 4), and cooking stages. Both models automatically realign the basket or drum at startup and after each cycle; do not open the door during realignment.
To start a manual cook on any model, press the ON/OFF button, set the desired temperature and time using the respective buttons and the plus/minus keys, then press START/STOP. For stored recipes, navigate to the recipe list menu, select the program, and start. Always ensure the basket or drum is properly seated and free to rotate before beginning a cycle.
Cleaning and routine care
Before any cleaning, disconnect the appliance from the power supply and allow it to cool completely. Wear appropriate personal protective equipment such as gloves. The Spriz installation and maintenance manual (EFE12B) instructs users to clean the door, interior glass, cooking chamber, and external surfaces with non-abrasive products, avoiding scrapers or aggressive chemicals. For first use, remove all protective film and clean the interior thoroughly.
For Hop Air Fryers, the EFE35SPVB operation manual recommends a first cleaning by heating the empty appliance to 204°C for 30 minutes to eliminate manufacturing odours, then wiping the chamber with hot water and soap. Routine cleaning involves washing the cooking chamber, basket, and tray. The EFE475PRO manual adds steps for removing the removable drum, internal drum, and front deflector for separate cleaning. Ventless models (Hop Air Pro) also require periodic cleaning of the air filter and replacement of the active carbon filter, as detailed in that manual. Always rinse away all detergent residue to prevent corrosion, and never use acidic or abrasive cleaners on stainless steel surfaces.
Troubleshooting common issues
On the Spriz, a camera (chamber) probe failure means the probe is shorted, interrupted or out of range; it stops any cooking in progress and resets itself once the cause is removed. The safety thermostat alarm means the maximum operating temperature was exceeded: check that the cooling fan filters are clean and the installation distances respected, then, with the oven cooled and the door open, remove the cap on the back and press the red button. If it trips repeatedly, wait for a technician rather than resetting it again. After a power cut of less than a minute, a cooking cycle resumes where it stopped with an alarm; after longer, it does not restart on its own.
On the Hop Air Pro, alarms flash on the upper display with a beep that any key silences, and clear once the cause is gone. Er1 means the chamber temperature probe is faulty or disconnected, and Er2 a fault in the motor that turns the drum; both are for a skilled technician. To reset its safety thermostat, let the oven cool completely, unscrew the protective cap on the back and press the button until it clicks; the manual advises doing this with a qualified technician, and replacing the part if it trips often. Its fault table adds: water from the cooking chamber (check the discharge pipe), steam from the carbon filter cartridge (clear the air vents or have the condensation system cleaned) and strong cooking smells (replace a worn carbon filter or put it back in place).
When to call for service
All extraordinary maintenance, component replacement, and repairs must be carried out by an authorized service centre. The user is responsible only for routine cleaning. If the equipment malfunctions or shows structural or functional anomalies, disconnect it from the power supply and contact a service centre authorized by the manufacturer. Norpex does not provide installation or repair services; for service, refer to the manufacturer's authorized network. For questions about a specific model, ask Norpex.
Common questions
What are the clearance requirements for EcoFry Hop Air Fryers?
- For non-combustible walls, allow 100 mm on the sides and back; for combustible walls, allow 500 mm on the sides and 700 mm on the back, as stated in the operation manuals for EFE35SPVB and EFE475PRO.
How do I clean the cooking chamber of a Spriz speed oven?
- Disconnect power, let the oven cool, and wear protective gloves. Clean the interior with a soft cloth and non-abrasive detergent, then rinse thoroughly. Avoid abrasive tools or aggressive chemicals, as per the Spriz installation and maintenance manual.
Can I operate the EcoFry air fryer without the basket rotating?
- Yes. On the EFE35SPVB the basket rotation can be set from 0, always stationary, up to 4/4, always rotating, with intermediate settings such as 1/4, which turns for 3 seconds and pauses for 27. The basket realigns itself at start-up and after each cycle.
What should I do if my EcoFry oven displays an error or alarm?
- Read the alarm on the display. A probe alarm needs a technician; a tripped safety thermostat is reset by hand at the back of the oven once it has cooled, and if it keeps tripping a technician should check it. If the problem persists, disconnect power and contact an authorized service centre.
Do I need a water connection for my EcoFry air fryer?
- Some Hop Air Fryer models, like the EFE35SPVB, require a water inlet connection with specific water quality (hardness 60–90 ppm, pressure 150–200 kPa) and a drain connection. The Spriz speed ovens do not require a water connection; they use a fumes exhaust chimney that can be vented or condensed with an optional hood. Check your model's manual for exact requirements.
