Installation Instructions

WARNING: Installation must be carried out by a qualified person.

1. Pre-Requirements

Needed equipment includes:

• Suitable power supply cable (usually 12-2+Ground) protected by flexible conduit.
• A by-pass kit (3-way valve), PVC pipe and fittings, pipe cleaner/primer, medium-bodied glue.
• Electrical tools and a multimeter.
• A service disconnect or timer within 6 feet of the heater.
• An equipment pad (16” x 32” x 4” thick) or two concrete blocks (16” x 16” x 4” each).

2. Location

Follow these rules for heat pump location:

• Do not install directly below roof drains, gutters, or eaves.
• Ensure the heater does not submerge in water during heavy rain.
• Install drain adapters and attach a hose to direct condensation water. The unit produces gallons of water daily.
• Confirm the unit is in a well-ventilated area; the fan discharge grill must not be blocked.
• Maintain at least 12 inches of clearance on the two short sides and the long radiator side.
• Maintain at least 3 feet of clearance on the fan side.
• Keep the unit away from children's reach and within 25 feet of the pool.

Free space requirement for the horizontal heat pump:

Diagram shows required clearances: 12 inches on sides, not less than 24 inches on top, and 36 inches for air outlet. Service panel access is also indicated.

DRAIN ADAPTERS

Install drain adapters beneath the heater. A 5/8" hose can be added to direct condensation water.

Images show the installation of drain adapters.

PLUMBING

• For typical installations with small pumps (½, ¼ hp) and 1 1/2" pipes, connect pipes from bottom and exit through top.
• For stronger systems (1.0 Hp and larger pumps) and 2-inch plumbing, a bypass system is recommended.
• If connecting to a filtration circuit with a bypass valve, partially open (throttle) the bypass valve while opening others completely. Start with 50% bypass and adjust to achieve optimal water flow without error messages (EE-3, PL, EE1).
• The new FibroPool bypass valve uses a single valve, simplifying adjustment compared to older systems with three valves.

Images show the installation and adjustment of a bypass valve.

PIPE CONNECTIONS

• The FH 270 features 1 1/2" SAE machine threads. Use the included unionized fittings with o-rings (no thread tape) or conical hose adapters with thread tape.
• Use 1 1/2” Sch 40 PVC pipe for all fittings and pipes.
• Tighten fittings by hand. For threaded hose adapters, use pliers for an additional ¼ turn after hand-tightening to avoid cracking fittings.
• Ensure a minimum of 6 inches of straight pipe before any elbows or fittings.
• Support pipes in the air to prevent bending or breaking due to gravity.
• Ensure flexible hoses are securely clamped.
• Check and glue fittings properly using pipe cleaner and medium-bodied glue.
• Heaters have heat exchanger coils that increase back pressure.
• If your pool pump is larger than 1 horsepower, use a bypass valve (3-way valve and a Tee) to maintain original water flow.
• For 2-inch plumbing, use a 2-inch bypass valve and Tee, then reducers to 1 1/2" pipe for connection to the heater.
• Ensure the WATER IN pipe is connected to the bottom and the WATER OUT pipe is on top. Reversal will cause flow error codes.

ELECTRICAL CONNECTIONS

Power Supply Wires Size

WARNING: Disconnect power supply before any operation.

• Step 1: Detach the front panel with a screwdriver.
• Step 2: Insert the cable into the heat pump's electrical connector port (designed for outdoor SO cords). If using flexible conduit, remove the adapter and install a conduit adapter.
• Step 3: Connect the power supply cable to the terminal block according to the diagram.

Diagrams show the terminal block connections (L1, L2, G) and the power supply (208-246 VAC, 60Hz).

Important Notes:

• The FH 270 does NOT have a NEUTRAL connection. Do NOT use a GFCI breaker.
• The FH 270 requires equipotential bonding. Connect an #8 AWG bare copper wire to a ground rod for safety and corrosion prevention.

Images show the electrical box, internal wiring, and grounding connection.

Running Test

Inspection Before Running Test

1. Check electrical connectors and terminal screws for tightness.
2. Verify power supply voltage is 208-240 volts.
3. Check the tightness and attachment of the bonding wire to the ground rod.
4. Check plumbing connections; ensure they are glued, tight, and correctly connected (IN from BOTTOM, OUT from TOP).

Turn on the pump

Wait about 1 minute for air to purge from the system.

Turn on the heater

Push the ON/OFF button. Ensure the SUNSHINE sign is illuminated. Allow approximately 5 minutes for the fan to start blowing cold air and condensate water to begin dripping. This indicates the heater is working.

If all is well, leave the heater running. The heater operates only when the pump is ON. In and out temperatures may be close, depending on pump flow rate. Cold air and condensation are the primary indicators of heating.

COMMON QUESTIONS ASKED

POOL NOT HEATING:

• In and out difference too small: May indicate low air humidity or excessive pool pump flow. A difference of 0-4 degrees is accepted; higher humidity allows for a greater difference.
• Initial heating takes time: Allow several days for heating, running the pump and heater 24/7, and keeping the pool covered.
• Heater is not working: Indicators of operation include blowing cold air, compressor pressure increase (approx. 0.5 MPA), and dripping condensation water after 10-15 minutes. If these occur, the heater is functioning.
• Heater is not leaking water from the bottom: Condensation is normal and drains from the bottom.
• The air is too dry: Optimize heat pump performance by installing micron misters near the coils to add moisture to the incoming air.
• Pool pump's timer setting is too short: Ensure the pool pump runs long enough for the heater to operate effectively. Adjust timer settings or remove the timer.
• Fan not coming on, pressure not rising: If the fan doesn't start within 4 minutes and the compressor doesn't engage within 45 seconds, there might be a mechanical issue or an error message on the screen. Contact Fibropool Co.
• Pool is too big for the heater: Consider adding a second heater.
• Air is too cold: Heat pumps perform poorly below 60°F. Wait for warmer weather.

HEATER IS GIVING WATER FLOW ERROR (PL):

• Pool pump is OFF.
• Pool pump is weak.
• Pool filter is dirty.
• Plumbing is connected backwards (water IN at top).
• Bypass valve is set incorrectly.

HEATER IS VIBRATING/ SHAKING HEAVILY:

• Loose or broken fan blade.

NO DISPLAY:

• Digital controller is damaged (protective cover broken/missing).
• Incoming power is not 208-240 volts.
• Motherboard's fuse is blown.

MAINTENANCE

• Leave the heater on continuously during the season, adjusting only the temperature. Keep electronic circuits dry and warm.
