Product Components
The choosmo Variable Speed Pool Pump package includes the following items:
- choosmo Variable Speed Pool Pump (1.5HP)
- 2 x 2" Adapters
- Instruction Manual

The pump comes with 4 adapters (2 male threaded, 2 female threaded) and O-rings to ensure secure, leak-free connections to 1.5-inch plumbing tubes.
Setup and Installation
1. Placement
Position the pump on a firm, level surface as close to the pool as possible to minimize friction loss in the suction line. Ensure adequate drainage and ventilation around the pump.
2. Plumbing Connections
Connect the pump to your pool's plumbing system using the provided 2-inch adapters. Ensure all connections are tight and sealed with appropriate thread sealant to prevent leaks. The pump is compatible with both sand and cartridge filter systems.

3. Electrical Wiring
The pump supports dual voltage operation (115V/230V). Ensure the pump is wired correctly for your electrical supply. This procedure should only be performed by a qualified electrician. The pump includes a 6-foot power cord.

4. Priming the Pump
Before starting the pump for the first time, or after cleaning the filter basket, it is crucial to prime the pump. Remove the clear lid of the filter basket and fill the basket with water until it reaches the suction pipe level. Replace the lid securely. This ensures the pump does not run dry, which can cause damage.

Maintenance
Regular maintenance ensures the longevity and efficient operation of your choosmo pool pump.
1. Filter Basket Cleaning
The extra-large filter basket collects leaves and debris, preventing them from entering the pump impeller. Regularly check the transparent lid to see when the basket needs cleaning. A clogged basket reduces pump efficiency.
- Turn off the pump and disconnect power.
- Rotate the clear lid counter-clockwise to remove it. The lid has hand grips for easy removal.
- Lift out the filter basket.
- Empty all debris from the basket and rinse it thoroughly with water.
- Inspect the O-ring on the lid for cracks or wear. Replace if necessary.
- Place the clean basket back into the pump housing.
- Fill the basket with water to prime the pump.
- Replace the lid, ensuring the O-ring is properly seated, and tighten clockwise until secure. Do not overtighten.
- Reconnect power and restart the pump.

2. General Cleaning
Wipe down the exterior of the pump with a damp cloth as needed to keep it free from dirt and dust. Avoid using harsh chemicals or abrasive cleaners.
3. Winterization
In areas subject to freezing temperatures, the pump must be properly winterized to prevent damage. Consult a pool professional for specific winterization procedures for your region.
