Astralpool Fan Cowl 40274 - Notos 3 HP and Notos Three-Phase Pool Pump Motors

Astralpool Fan Cowl 40274 - Notos 3 HP and Notos Three-Phase Pool Pump Motors

This is the genuine Astralpool Fan Cowl, part number 40274, for the Notos 3 HP motor and all Notos three-phase motors. Fluidra describes it as the Fan Cowl 3HP All 3 Phase Notos. It covers the Notos 3 HP and three-phase cooling fan 40275. The 750W to 1500W single phase Notos motors take a different cowl, 40283. One cowl per pump.

• Physically Stocked, unlike most "drop-shipping" websites.
• Shipped from VIC, NSW, WA, QLD

Confirmed Compatibility

Fluidra's description ties this cowl to the motor, not the pump: the Notos 3 HP motor and every Notos three-phase motor. Astralpool's pumps manual H0717800 gives these 3 HP and three-phase motor numbers for the XP. The lists do not say which of these motors are Notos motors, so confirm your motor before ordering.

Astralpool's 2014 CTX and BX spare parts lists also include the 2200W motor 71331 (the 3 HP motor in Astralpool's pumps manual), which dealers list for the CTX 610, BX 3.0 and XP 3.0. Those 2014 lists, and the 2017 CX list, describe 71331 as beige, while Fluidra now supplies 71331 as a black 2200W motor, and Fluidra lists a separate cowl, 40262, for its Fasco 2400W 3 HP motor. A 3 HP pump can therefore have more than one type of motor, so check the motor before ordering.

Not this cowl: the 750W, 1100W and 1500W single phase motors take 40283 (black Notos) or 40257 (beige Fasco). The Viron pumps take 70600. The Fasco 2400W 3 HP motor takes 40262.

Ask first: any 3 HP motor that is beige, and any motor you are unsure of. Send us a photo of the motor, its data plate and the old cowl.

Dimensions and Specifications

The Notos 3 HP Cowl Rule (rev. N3C-1.0)

Confirm this cowl by the motor:

1. 3 HP or three-phase? Read the data plate. A Notos 3 HP motor, or any Notos three-phase motor, takes this cowl and the fan 40275. Astralpool's XP motor numbers are 71331 (3 HP) and 71320, 71335 and 71338 (three-phase).
2. Beige 3 HP motor? Ask first. Astralpool's 2014 CTX and BX lists describe 71331 as beige, Fluidra now supplies it black, and Fluidra lists cowl 40262 for its Fasco 2400W 3 HP motor. Send us a photo before ordering.
3. 750W to 1500W? Different cowl. Black Notos 750W, 1100W and 1500W motors take 40283, and beige Fasco motors of those sizes take 40257.
4. Viron? Different cowl. Viron XT and Viron eVo pumps take 70600.

What the Fan Cowl Does

These pump motors are air cooled. The fan on the rear of the motor shaft draws air in through the cowl and pushes it along the motor body, and the cowl guides that air and keeps fingers and debris away from the spinning fan. Astralpool's Viron XT installation manual says the pump must have proper ventilation to prevent the motor overheating, that overheating due to lack of cooling voids the warranty, and lists poor airflow over the motor as a cause of the HI T over temperature fault. A single speed pump has no display to warn you that it is running hot.

The same manual says to check the surroundings for leaves and debris and, with the power off, to spray a surface insecticide around the control every three months, because ants and some insects are attracted to the warm, dry environment inside the enclosure.

Astralpool Motor Fan, Cowl and Clip Chart

Part numbers and descriptions are from Astralpool's pump spare parts lists, Fluidra's electric motor spare parts list and part descriptions, and Astralpool dealer listings (40263 and the 40284 560W description). "None listed" means no separate clip appears on those lists. "Ask us" means the lists do not show the part; send us a photo of the motor data plate and the old part.

Fitting Notes

Isolate the pump at the power point or switchboard before removing the cowl. Astralpool's pump manuals say the pump must be installed and serviced by a licensed electrician in accordance with AS/NZS 3000.

1. Remove the old cowl from the rear of the motor, noting how it locates.
2. While it is off, check the fan and its clip, and replace them if they are cracked, chipped or loose.
3. Fit the new cowl the same way round, make sure it is fully seated, and turn the fan by hand to check it does not touch the cowl.

When to Replace

Astralpool's maintenance schedules give no service interval for the fan cowl. Replace it when it is cracked, broken, distorted or missing, or when the fan has been hitting it.

Frequently Asked Questions

Which motors does the 40274 cowl fit?
The Notos 3 HP motor and all Notos three-phase motors, per Fluidra's description. Astralpool's pumps manual gives the XP motors as 71331 (3 HP single phase), 71320 (1 HP three-phase), 71335 (2 HP and 3 HP three-phase) and 71338 (4 HP three-phase), but does not say which are Notos motors. Check the motor first, because some 3 HP pumps were built with a beige motor.

Does it fit the CTX 610 or BX 3.0?
Only if the motor is a Notos 3 HP motor, which the parts lists do not confirm for these pumps. Dealers list the 2200W motor 71331 for the CTX 610, BX 3.0 and XP 3.0. Astralpool's 2014 CTX and BX lists describe 71331 as beige, so if your motor is beige, send us a photo first. Fluidra lists cowl 40262 for its Fasco 2400W 3 HP motor.

Is the fan included?
No. The fan is 40275, sold separately.

Does it fit a 1500W motor?
No. Black Notos 750W, 1100W and 1500W motors take 40283, and beige Fasco motors of those sizes take 40257.

Is this a genuine Astralpool part?
Yes. Heater and Spa Parts is an authorised Fluidra (Astralpool and Zodiac) dealer and warranty agent, and 40274 is the genuine Astralpool part, barcode 9343609059132.

Can I fit it myself?
Isolate the pump from power first. Astralpool's pump manuals say the pump must be installed and serviced by a licensed electrician in accordance with AS/NZS 3000. As with all of our products, it must be diagnosed and fitted by a qualified and experienced person.
