Installation Instructions
WARNING: Installation must be performed by a qualified person
This section is provided for information purposes only and may vary depending on your
location, regulations, and available space for installation
1. Pre-Requirements
Required equipment for installation of heat pump:
Suitable power outlet, 110-125 volts, GFCI protected outlet
PVC pipe and fittings OR Corrugated filter connection hoses and necessary adapters, Pipe
cleaner/ primer, Medium Bodied Glue
Electrical tools, and a multi-meter
An equipment pad, 16” x 32” x 4” thick or 2 pieces of concrete blocks, 16 x 16 x 4 inches each
2. Location
Please consider the following when choosing a location for the heat pump:
1 Make sure the heater is not directly below roof drains, such as a gutter drain, or eaves
2 Be sure that the heater does not submerge in water in heavy rain
3 Be sure to install the drain adapters into the heater and attach the hose to direct the
condensation water Heater will produce gallons of water from condensation daily
4 Confirm the unit is in well-ventilated conditions and that the fan discharge grill vent is not
blocked (fan blows outwards )
5 Keep at least 12 inches of clearance on the two short sides and the long radiator side
6 Keep at least 3 feet of clearance on the fan side of the heater
7 Keep the unit as far as possible out of the reach of children and within 25 feet of the pool
V.23.02 FIBROPOOL USA

DRAIN ADAPTERS
Please install the drain adapters beneath the heater prior to installation You can attach 5/8” hose
to the adapters to direct the condensation water
PLUMBING
·On a typical installation on a pool with a small pump, such as ½, ¾ hp pump with 1 1/2”
PVC or flexible hoses, only the plumbing IN from the BOTTOM and OUT from the TOP pipe
connection is necessary
·For stronger systems (those with 1 5 HP and larger pumps and 2 inch plumbing systems) a
bypass system should be installed
·** A BYPASS SYSTEM IS NOT NECESSARY FOR ABOVE GROUND POOLS****
·If the heat pump is connected to a filtration circuit with a by-pass valve: We suggest to open
the bypass 50% then adjust down to achieve the lowest flow rate into the heater without
triggering error messages (EE-3, PL, EE1) This will give enough water to the heater without
restricting the flow The IN and OUT difference should be 1-5° Fahrenheit If the difference
is too great, increase the water flow through the heater for optimal heating
·The old system BYPASS path usually consists of 3 valves The New FIBROPOOL BYPASS
VALVE is just 1 valve This makes it possible to adjust water flow passing through the heat
pump

PIPE C NNECTI NS
1. FH 135 Features 1 1/2” SAE machine threads They are NOT the typical pipe threads You
can use the included unionized fittings with o-rings WITHOUT thread tape, or you can use
the conical hose adapters WITH thread tape
2. All fittings and pipes used must be 1 1/2” Sch 40 (Schedule 40) PVC pipe If using
corrugated flexible filter hoses, try to use the 1 ½” diameter hoses
3. Tighten all fittings by hand only If using the threaded hose adapters with thread tape, give
a ¼ turn with pliers after hand tight Excessive tightening will crack fittings
4. A minimum of 6 inches of straight pipe must be used before any elbows/fittings etc
5. Please support the pipes in the air, as gravity will eventually bend and break the fittings
6. If using flexible hoses, be sure to tighten the clamps well
7. Be sure to check your fittings and glue them properly, using pipe cleaner and a good grade
Medium bodied glue
8. Heaters have heat exchanger coils, therefore they increase back pressure
9. If your pool pump is larger than 1 horsepower, you should use a bypass valve This will help
water flow of your system to continue as original plumbing You simply need a 3 way valve,
and a Tee Refer to diagrams for the bypass set up
10. If you have 2 inch plumbing, use our 2 inch bypass valve and a 2 inch TEE, then use
reducers to 1 1/2” pipe to connect to the heater This way you will not compromise the water
flow
11. Be sure that WATER IN pipe is connected to the BOTTOM, and WATER OUT pipe is on
TOP Reversal will result in flow error code PL

➢Step 1: Remove the 8 screws that are holding down the top lid of the heater ( yellow
stickers pointing to them). All adapters etc are inside the heater contained in a bag.
➢Step 2: Remove the bag and reinstall the lids 8 screws hand tight.
➢Step 3: Plug in the power cord of the heater and reset the GFCI by pushing the TEST
and RESET buttons.
➢FH 135 requires equipotential bonding. Please connect an #8 AWG bare copper wire to a
ground rod. This is required for safety and corrosion prevention of the heater’s metal
chassis.
V.23.02 FIBROPOOL USA

Running Test
Inspection Before Running Test
1. Check electrical connectors terminal screws. Be sure all are tight
2. Check voltage at the power supply 110-125 volts range must be observed on the outlet
3. Check Bonding wire's tightness and attachment to the ground rod.
4. Check plumbing connections make sure all glued tight and IN from BOTTOM OUT from
TOP
Turn on the pump………………….
………………………..Wait about 1 minute for all the air to purge from the system
Turn on the heater
Push the ON/OFF button on the heater Making sure the SUNSHINE sign is on top……………...
……………….ALLOW ABOUT 5 MINUTES FOR THE FAN TO START BLOWING COLD AIR AND
CONDENSATION TO START DRIPPING.
These indicate the heater is running. Another indication of the heater operating properly is the
pressure gauge on its side will climb up.
If all is well leave your heater running. Your heater will only be on while your pump is ON
In and out temperatures maybe very close or even the same but this depends on many
factors including a strong pump pushing the water too fast to register.
The primary indicators of heating are cold air and condensation.
The Pressure gauge is oil filled with an air bubble. Do not mistake it for an oil or water leak.

WE DO NOT RECOMMEND CHANGING FACTORY SETTINGS. THERE IS NO FACTORY
SETTINGS- RESET BUTTON. THE ONLY OPTION IS TO REPROGRAM THESE FUNCTIONS
INDIVIDUALLY OR REPLACE THE MOTHERBOARD. IN MOST CASES THE ERROR/
PROBLEM WILL GO AWAY BY RESTARTING THE SYSTEM. TURN OFF THE BREAKER FOR
45 SECONDS AND TURN IT BACK ON. THIS WILL ERASE THE SENSORS' MEMORY.
V.23.02 FIBROPOOL USA

BELOW ARE COMMON QUESTIONS ASKED
To resolve a problem, we nee to i entify whether it is a mechanical problem, or performance.
POOL NOT HEATING:
•In and out difference too small: Either the air humidity is too low, or the pool pump is
pushing too hard Difference 0-4 degrees accepted Higher humidity (80% or higher)
equates to higher difference
•Initial heating takes time Allow a few days for the water to heat up, leaving the pool pump
and heater on 24-7 Covering the pool can dramatically speed up heating
•Heater is not working: There are 3 basic indicators of the heater’s operation: 1- heater
blowing cold air 2- compressor pressure goes up by about 0 5 MPa 3- heater dripping water
from the condensation lines after 10-15 minutes If any of these conditions are observed,
the heater is working
•Heater is not leaking water from the bottom: Heat pumps will create quite a bit
condensation, which will drain from the bottom of the heater
•The air is too dry: Pool heat pumps are optimized for 80% humidity If the humidity is
significantly lower, we recommend installing a set of micron misters A set can be purchased
for about 20-30 dollars from hardware stores These sets typically screw into a garden hose
and spray mist Place the heads near the coils in order to increase the available moisture for
the system, boosting performance
•Pool pump's timer setting is too short: Pool heaters are fed by the pool pump’s
circulation A shorter pump timer will result in a shorter heating period Please adjust the
timer settings on your pump or remove the timer when heating
•The fan is not coming on the pressure is not going up on the pressure gauge: When
the thermostat calls for heat, the fan will come on within 4 minutes, and within 45 seconds,
the compressor will kick in If this doesn’t happen, and the pool water temperature is much
lower than the desired temperature, there is a mechanical issue of an error message on the
screen Be sure that there is no error messages on the screen This may require a phone
call to us at Fibropool Co 1 228 313 7874
•Pool is too big for the heater or for your climate zone: There is not much can be done,
except adding a second heater into the system
•Air is too cold: Heat pumps absorb heat from the air If the air too cold-below 60°F-
performance will be extremely weak This is often a sign that the swimming season in your
area is over
HEATER IS GIVING WATER FLOW ERROR (PL)
•Pool pump is OFF
•Pool pump is very weak
•Pool filter is dirty
•Plumbing is connected backwards, cold water is connected to top
•Bypass valve is set incorrectly, and water is not being allowed through the heater.
•Flow switch is malfunctioning.
HEATER IS VIBRATING/ SHAKING HEAVILY
•Loose or broken Fan blade
NO DISPLAY
•igital display is damaged. This happens most frequently if the protective cover is broken or missing,
making the controller NOT weather proof.
•The incoming power is not 220 volts. Reading between L1 and L2 should be between 208-240 volts.
•Motherboard's fuse is blown.

MAINTENANCE
•For best performance, we recommend setting the temperature and allowing your heater to
run as much as possible Electronic circuits should stay dry and warm with electricity
• Clean your pool's filtration system regularly to avoid damage to the unit due to a dirty or
clogged filter
• Winterize properly by making sure no water remains in the heater’s tank If possible,
bring the unit inside during winter to minimize risks
• After the unit is winterized, it is ideal to cover the unit with the special winter heat pump
cover
• Please keep the coils clean, by using “Foaming air conditioner coil cleaner”, available at
hardware stores
•Winterization: If the unit is not running during winter months, please disconnect
power supply and pipes, and let out drain water from unit by tilting the heater toward the
water inlet side by 45 degrees A shop vac can also be used for this
•Winterization: if you want to move the unit indoors, just disconnect everything and
take it into your garage
