FibroPool FH235-I 35,000 BTU Full Inverter Heat Pump

WARNING
Risk of electric shock!

• A faulty electrical installation or excessively high voltage can lead to electric shock.
• Installation of heat pumps should only be performed by an authorized technician.
• Always disconnect the power supply before opening the heat pump for maintenance or repairs.
• Do not connect the heat pump if the incoming voltage does not match the required voltage on the unit’s information plate.
• Do not operate the heat pump if there is visible damage to the incoming wiring.
• Repairs should only be performed by a qualified technician unless otherwise instructed. Liability and warranty claims are excluded in the event of improper repairs.
• Keep children away from the heat pump.
• Ensure that the heat pump’s wiring is properly grounded or bonded before operating.

ATTENTION

• The manufacturer is not responsible for damage caused by people, foreign objects, or inappropriate installation against these guidelines.
• Always provide proper ventilation and install it away from any fire risks.
• Do not disconnect or attempt repairs on any lines containing refrigerant. Refrigerant repairs should not be performed in any confined space.
• It is vital to follow proper winterization procedures when the risk of hard freeze approaches, or the titanium heat exchanger risks being cracked or damaged. Such damage is not covered under the warranty and repairs will be the owner’s responsibility.

Included Parts and Accessories

Each unit includes the following accessories

The heat pump requires the following components:

NOTE

The exact amount and setup of the plumbing, valves, filter equipment, sterilizing equipment, etc. vary from one pool to another. At a minimum, a pool pump and filter are required. It is not recommended to install auxiliary electric heaters in the system. If absolutely necessary, auxiliary heaters must be installed and operated by qualified technicians. Fibropool cannot provide support for auxiliary heating systems.

Heat Pump Overview

Safety Information

Required Operating Conditions:

1. Power supply: 208-230V 50/60Hz.
2. Air temperature: 35°F-105°F
3. Water temperature range:
4. 45°F-104°F in Heating Mode
5. 45°F-82°F in Cooling Mode

NOTE: Operating heat pumps at near-freezing temperatures risks damage to the heat exchanger. Heat pumps must be empty of water at freezing temperatures. See winterization guidelines for more details.

• Verify the ground connection before operation. Improper grounding increases the risk electric shock and death.

Grounding protects both swimmers and technicians from electric shock. It is absolutely necessary to properly ground the unit.

• Heat pumps should be installed outdoors when possible. If necessary, indoor installations must have adequate ventilation and clearance.
• Keep children away from the heat pump. The lock function can be used to prevent improper operation.
• Keep fingers and other objects away from the fan. Fan blades are extremely sharp and can cut or damage objects put inside.
• If you notice any unusual sounds, burning smell, electrical shorts, etc., please immediately disconnect the heat pump and contact Fibropool support.
• Do not install the unit near any combustible objects or materials.
• Install the heat pump such that the base rests on a solid, level foundation.
•  When cleaning the unit, the heat pump should be off and disconnected from any power source.

Initial Operation

Attention

• When first connected, allow water to flow through to purge air from lines.
• Always inspect electrical connections before operation. Verify that the grounding lug is attached to a grounding rod or pool bonding according to local electrical codes.

Preparation Before Adjustment

• Ensure the system is installed correctly according to these guidelines.
• Check that water connections are secure and in the correct positions.
• Verify supply voltage is sufficient for heat pump operation.
• Verify adequate ventilation around the unit

Operating Instructions

To ensure proper operation, frequently inspect water and electrical connections. Follow the guidelines below when performing maintenance or repairs:

• Always disconnect the incoming power from the breaker or a shutoff switch before opening the unit.
• Unless necessary or instructed by Fibropool, most default settings do not need to be adjusted.
• Frequently inspect electrical connections for loose or damaged wiring and components.
• Evaporator fins should be cleaned when dirty or every six months. An air compressor can safely remove most dirt and debris. A damp cloth can be used, but use caution as the fins are sharp and may tear the cloth and cut skin.
• After long periods of inactivity (after winterization, for example): inspect and clean all equipment, flush plumbing, inspect the pool pump, and recheck and tighten all electrical connections.
• Aftermarket replacement parts are not recommended and cannot be supported by Fibropool. Visit www.fibropool.com for replacement parts or contact technical support for assistance.

Draining Heat Exchange
When not installed for prolonged periods of time or in anticipation of a hard freeze, the heat pump should be completely drained by tilting the outlet at least 45°. A shop vac is recommended to remove any remaining water. Plug the water inlet and outlet before storage to prevent insects and rodents from entering the tank.
Warning: A heat exchange cracked due to freezing is not covered under the warranty for this product. It is the homeowner’s responsibility to observe proper winterization procedures. See section XI: Maintenance and Winterization for more details.

Maintenance

Maintenance and Winterization

• For best performance, we recommend setting the temperature and allowing your heater to run as often as possible.
• Clean your pool’s filtration system regularly to avoid damage to the unit due to a dirty or clogged filter.
• Keep the coils clean by using a foaming air conditioner coil cleaner or pressurized air from an air compressor or air duster.
• Winterization: If the unit is not running during winter months, disconnect the power supply and water connections, and drain water from the unit by tilting the heater toward the water inlet side at a 45-degree angle. A shop vac can also be used.
• Winterization: If possible, store the unit indoors after disconnecting to minimize risks of freeze damage or excessive wear due to winter conditions.
• After the unit is winterized, it is ideal to cover the unit with a tarp or similar cover.

Warning: A heat exchange cracked due to freezing is not covered under the warranty for this product. It is the homeowner’s responsibility to observe the proper winterization procedure
