Installation Instructions
WARNING: Installation must be carried out by a qualified person
This section is provided for information purpose only and may vary depending on your location/
regulations/ availabl spac for installation
1. Pr -R quir m nts
Needed equipment for installation of heat pump:
Suitable power supply cable for unit’s power 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 2 pieces of concrete blocks, 16 x 16 x 4 inches each
2. Location
Please comply with the following rules about heat pump location choosing
1 Make sure the heater is not directly below the roof drains, such as 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 heaters, and attach the hose to direct the
condensation water Heater will produce gallons of water from condensation, every day
4 Confirm the unit is under well-ventilated conditions; 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 away from children's reach and within 25 feet of the pool
V-2105 Fibropool Co LLC, Ms USA

DRAIN ADAPTERS
Please install the darin adapters beneath the heater prior to installation You can add 5/8 hose to
the adapters to direct the condensation water
PLUMBING
·A typical installation on a pool with a small pump, such as ½, ¾ hp pump with 1 1/2” pvc or
flexible pipes, just requires pipes to go in from the bottom and exit thru top
·For stronger systems, with 1 0 Hp and larger pumps, and 2 inch plumbing systems, a bypass
system should be installed
·If The heat pump is connected to a filtration circuit with a by-pass valve; The bypass valve
should be partially opened (throttled), while all the other valves should be completely
opened We suggest to open bypass 50% then adjust until the lowest volume of water going
through the heater, but no error messages ( EE-3, PL, EE1) are present This will give
enough water to the heater, and not restrict your flow
·The old system BYPASS path usually consists of 3 valves The New FIBROPOOL BY PASS
VALVE is just 1 valve That makes it possible to adjust water flow which passes through heat
pump

PIPE C NNECTI NS
1. FH 270 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
3. Tighten all fittings by hand only If using the threaded hose adapters, 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 continueas original plumbing You simply need to get 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 codes

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 diff r nc too small: Either the air humidity is too low, or the pool pump is
pushing too hard Difference 0-4 degrees accepted Higher the humidity ( 80% or higher),
higher the difference
•initial h ating tak s tim Allow a few days for the water to heat up, while leaving the pool
pump and heater on 24-7 And cover the pool with any type of cover
•H at r is not working: there are 3 basic indicators of the heaters 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 The problem is performance, not functionality
•H at r is not l aking wat r from th bottom: Heat pumps will create quite a bit
condensation, which will drain from the bottom of the heater
•Th air is too dry: Pool heat pumps are optimized for 80% humidity If the humidity is much
less, best thing is to install a set of micron misters A set can be purchased for about 20-30
dollars from hardware stores Which screws into the garden hose and sprays mist Place
the heads near the coils, this way the incoming air will draw moisture into the heater coils
and heat exchange rate will increase, thus resuting in better output
•Pool pump's tim r s tting is too short: Pool heaters need pool pumps circulation If the
pump doesnt run long enough, neither will the heater Please adjust the timer settings on
your pump or remove the timer for heating
•Th fan is not coming on, th pr ssur is not going up on th pr ssur gaug : 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 doesnt 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 th h at r, for your climat zon : 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 60F, the
performance will be very little Your only option is to wait for warmer weather
HEATER IS GIVING WATER FLOW ERROR (PL)
•Pool pump is OFF
•Pool pump is really weak
•Pool filter is dirty
•Plumbing is connected backwards, cold water is connected to top
•By pass valve is set incorrectly, not allowing water to flow thru the heater.
HEATER IS VIBRATING/ SHAKING HEAVILY
•Loose or broken Fan blade
NO DISPLAY
•igital display is damaged. This happens mostly 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
•You should leave the heater on all the time, during the season Just adjust the temperature
and leave it on Electronic circuits should stay dry and warm with electricity
• Clean your pool's filtration system regularly to avoid the damage of the unit because of a
dirty or clogged filter
• Winterize properly by making sure there’s no water left in the heaters tank Or take it
indoors in the winter
• After the unit is conditioned in winter season, it is preferred 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
•Wint rization: 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 on the pipes
side by 45 degrees, or using a shop vac
•Wint rization: if you want to move the unit indoors, just disconnect everything and
take it into your garage
