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/ available space for installation

Pre-Requirements

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

Location

Please comply with the following rules about heat pump location choosing.

Make sure the heater is not directly below the roof drains, such as gutter drain, or
Be sure that the heater does not submerge in water in heavy
Be sure to install the drain adapters into the heaters, and attach the hose to direct the condensation Heater will produce gallons of water from condensation, every day.
Confirm the unit is under well-ventilated conditions; fan discharge grill vent is not blocked ( Fan blows )
Keep at least 12 inches of clearance on the two short sides and the long radiator
Keep at least 3 feet of clearance on the fan side of the
Keep the unit as far as possible away from children’s reach and within 25 feet of the pool

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 .

Installation of a Single Heater Parallel Installation for 2 Units

PIPE CONNECTIONS

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.
All fittings and pipes used must be 1 1/2” Sch 40 ( Schedule 40) PVC pipe
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.
A minimum of 6 inches of straight pipe must be used before any elbows/ fittings etc.
Please support the pipes in the air, as gravity will eventually bend and break the fittings.
If using flexible hoses, be sure to tighten the clamps well.
Be sure to check your fittings and glue them properly, using pipe cleaner and a good grade Medium bodied glue.
Heaters have heat exchanger coils, therefore they increase back pressure.
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.
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.
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.

ELECTRICAL CONNECTIONS

WARNING: Power supply of heat pump must be disconnected before any operation.

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

FH 270 does NOT have a NEUTRAL connection Therefore, Do NOT use a GFCI breaker.
FH 270 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 heaters metal chassis.

Running Test

Inspection Before Running Test

Check electrical connecors, terminal screws. Be sure all are tight
Check voltage at the power supply, 208-240 volts must be observed.
Check Bonding wire’s tightness and attachment to the ground rod.
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, CONDENSATE WATER TO START DRIPPING.
This is the indication of the heater working.If all is well, leave your heater running. Your heater will only be on while your pump is ONIn 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. Real indication of heating is cold air and condensation.

***************************************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. JUST TURN OFF THE BREAKER FOR 45 SEONDS AND TURN IT BACK ON. THIS WILL ERASE THE SENSORS’ MEMORIES.*************************************************************

To resolve a problem, we need to identify 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 the humidity ( 80% or higher), higher the difference.
initial heating takes time. 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.
Heater 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
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 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 timer setting 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.
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 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 the heater, 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 60F, the performance will be very little. Your only option is to wait for warmer weather.
