Introduction
Congratulations on purchasing the most advanced high efficiency,
microprocessor-controlled pool and spa heat pump available. Your heater has
been manufactured with the best state-of-the-art quality control equipment
available today to ensure the highest quality product delivered to your door. A
heat pump pool heater is a highly efficient, cost effective method of pool
heating. Proper operation and care will result in many years of swimming
enjoyment and pleasure.
Your new pool heater is a self-contained unit designed specifically for
swimming pool and spa heating. It utilizes the sun’s free energy by extracting
heat from the sun-warmed air and transferring it efficiently to the pool water.
Because your pool heater moves the free heat from the outside air to the pool,
rather than create heat, as a fossil fuel or electric resistance heater does, it
can heat your swimming pool or spa for up to 80% less cost than these other
less efficient methods.
As with all pool heating methods, you are advised to utilize a pool cover at
night and when the pool is not in use. The pool cover should be used if the
night temperature is 15˚F (8˚C) less than the desired pool temperature. This
will keep evaporation, the greatest source of heat loss, to a minimum, greatly
reducing the overall pool heating costs. During warmer weather, the pool
cover may not be required.
Your pool and spa heater combines simplicity with trouble-free performance.
As with most appliances, an understanding of proper operation of the heater
is important. Proper installation and operation increases efficiency and reduces
heating costs. Your pool heater is designed with features that make it simple
to operate, maintain and service. This manual will provide you with the
information needed to properly operate and maintain your heater.
ATTENTION:
Register your warranty at www.gulfstreamheatpump.com
Or be sure to complete and mail in the Warranty Registration Card
that is provided in the package with your heater.
Registration provides us with your information in case you need service.
Also, please take a moment and jot down the following information. If you
should ever need to call us for service or a question, we will need this

WATER CHEMISTRY MAINTENANCE
Not only is the water chemistry of your pool or spa important to the
health of you and your family, it also directly affects the life of your
heater. This is the most important item in the maintenance of the
heater. If the water chemistry is improperly maintained or if the
chemicals are improperly introduced into the water, this may damage
the heater’s internal components and could eventually cause a leak,
rendering the heater inoperable.
WARNING:
Do not store corrosive pool chemicals near the heater!
Following is the table for water quality readings, which should be maintained:
PH Level
7.4 to 7.8
1 time per week
Chlorine Concentration
1.0 to 3 PPM
1 time every 2 to 3
days
Total Alkalinity
80 to 120 PPM
1 time every 2 to 3
weeks
Total Dissolved Solids
Below 2400 PPM
1 time per month
Calcium Hardness
200 to 300 PPM
1 time per month
The location of the chemicals’ introduction to your system is also critical
to the heater’s life. If an automatic in-line Chlorinator is used (including
salt systems), it must be located downstream of the heater. A Trap/
Check Valve may also be installed between the chlorinator and the
heater to prevent chlorine return into the heater.
WARNING:
Never add chemicals into the pool skimmer.
Never leave any type of solid chlorine in the pool skimmer. This will cause a
high concentration of chlorine to enter your pool equipment, causing
premature corrosion.
Description Normal Range Verify
WARNING:
Make sure that there are NO SPRINKLER HEADS that spray near or
directly on the heater. This will cause expedited corrosion of the unit.

6
LOCATION OF HEATER
The unit is designed for outdoor installation and shall not be placed in a totally
enclosed area such as shed or garage. This will cause recirculation of cold
discharge air back into the evaporator coil and will greatly reduce heating
capacity and efficiency of the unit. This may void the compressor warranty
since it is over working the compressor.
If the unit is installed at the edge of a roofline, make sure the roof
has a rain gutter to prevent water from the roof pouring into the
heater.
The heater should be located as close to the existing pool pump and filter to
minimize water-piping length to reduce pool water head loss.
Your heater features an up-flow fan for quite operation. Air is pulled through
the evaporator coil and discharges through the top of the grill. At least 4 feet
clearance should be allowed above the unit for unrestricted air
discharge. The unit must not be installed under a porch or any kind of
overhang this will also cause cold air recirculation.
All sides of the heater should have at least 12 inches of clearance to
allow enough air to flow through the evaporator coil for optimal
heating. Restricting one side of the evaporation coil is permitted, however it
will cause a decrease in efficiency.
The unit should be mounted on a flat surface, preferably on a concrete or
fabricated pad. The surface should have a slight grade so condensation will
drain off the pad. The unit should be completely isolated from the building
foundation or wall; this will prevent the possibility of vibration sound
transmitting into the building.
INSTALLATION
Initial Installation Programming
Upon initial powering up of the unit, “LANGUAGE SELECT” will appear on the
display. Select your desired language using the up and down arrows and then
press “MODE”, select °F/°C in the “TEMP SCALE” selection. This install menu
will be on the display for 30 Seconds then the display will change to the
Operation Menu. From the Operation Menu you can adjust the set point. If the
30 seconds finished and you still need to adjust Language or Temp Scale, cut
the power off to the board and turn back on. The board will display the
“LANGUAGE SELECT” screen again for another 30 seconds. The factory settings
are English and ˚F.

7
TIE DOWN STRAPS
The base of the unit may be used to fasten
the unit in accordance with your local
building code. Attach two tie straps on
opposite sides of unit (See diagram HS1) and
anchor to the deck.
Diagram HS1
Installations Below Pool Level
When installing a heater below the pool level (and some solar installs),
adjustment to the pressure switch must be completed or the manufacturer may
require an external flow switch. This is to prevent the pressure switch from
falsely indicating water flow due to high head pressure of the water. Failure to
use an external flow switch may cause
the unit to activate without water
flow. The unit may go into “WATER
FLOW LOCKOUT”. You may install
the flow switch on the inlet or outlet
side of the plumbing. Wire the flow
switch into the space marked WPS
located on the bottom right corner of
the board. (See Diagram FS1).
Whitwires from the Water Pessure
Diagram FS1
Sub-Menu Access
To access the programming sub-menu (remote t-stat, solar, heat/cool,
calibration, load defaults etc) press and hold the up arrow and down arrow
at the same time until the board displays ”remote t-stat”. Use the MODE
button to scroll through the options and use the arrows to change settings.
If there are issues with the operation of the board, we suggest that
you “Load Defaults” to return to factory settings.
Pool Spa Automation (Remote Controls)
Attach the low voltage lines to the heater control board at the terminals
marked “Water Temp Sensor” (See diagram FS1 below). Access the sub-
menu by holding the UP Arrow and Down Arrow at the same time until the
board reads “Remote Thermostat Disabled”. Press the UP Arrow so that the
display reads “Enabled”. If left alone, the board will return to the main menu
and your remote system is now in control of your heat pump. We are unable
to assist with programming of your remote systems.

Solar Heat-pump Hybrid System Install
Instructions
This option will allow the Heat Pump to monitor the performance of the pool’s
solar heating system, and will automatically divert the water away from the solar
to prevent overheating or cooling of the water.
Installing the Solar after the Heat Pump: (Factory Recommended)
This form of the Hybrid System is the recommended installation from the factory.
Plumbing the Solar system after the heat pump will prevent from having flow
issues and from getting an incorrect current water temperature.
Installing the Solar before the Heat Pump:
(Not Recommended)
If you choose to install the solar before the heat pump you need to make sure
that you install a water temperature sensor on the water line after the filter and
before the solar. Otherwise you will not get the current water temperature on
the display screen. This can cause the heat pump to shut off before it reaches
the desired set point. The new sensor must be attached to the board on the
spades where the current WTS is attached.
Enabling the Solar Control:
Press and hold the UP and the DOWN arrows till the service menu appears. Use
the “MODE” button & scroll, when you see “SOLAR CONTROL”, Press the UP or
DOWN arrow to “ENABLE”, Do not touch anything else. The board will return to
the main screen.
Setting Temperature for Heat pump, and Solar:
To set the temperature, press “Mode” button until “Pool- Solar Heat” displays
on screen. Press the UP arrow until “POOL TEMPERATURE SETPOINT” displays
on screen. Once you set the desired pool temperature, then press the “Mode”
button so that the screen reads “POOL SOLAR SETPOINT”, set the temperature
desired for the solar. The temperature set point for the heater can be lower than
solar, but cannot be set higher; the heat pump will run until the set point for
the heater is satisfied and then allow the solar to continue to operate.
WARNING:
If you are installing heater to an exsiting solar system, please check the
condition of the low voltage wires and make sure the actuator switch is in the
“ON” position.

9
To install actuators, run wires from the actuators into control box of the unit. Then
connect the wires to the Pool/Spa valves terminals on top of the board (See Diagram
MVA1). Make sure you cam the valves
correctly before running water through the
system. The valves will automatically turn
When the spa mode in activated.
There are two ways you can operate the
GPS automation:
1. Use the MODE button on the unit to
switch from Pool to Spa.
2. Wire an external switch to the T-Stat
Pool/Spa terminal on top right hand corner
of board (See Diagram MVA1). There is no
programming. Activating the external
switch will change the mode and valves
from Pool to Spa. This can also be activated by a network communicating switch via
an App on your mobile device. Additional wiring required. Call service more additional
wiring and details of this feature.

Plumbing Sequence
The piping sequence is: pool pump – filter – heater – solar - chlorination system(s) – pool.
Rigid PVC piping is recommended and all joints secured with PVC glue. Installation MUST
conform to all local codes. Make sure water-flow is correct as indicated on back of heater.
Again, try to keep piping away from areas that may be tripped over or stepped on when
operating heater or servicing. Try to keep elbows and piping to a minimum to avoid
excessive pressure drop. We use a full-flow heat exchanger so no external bypass is
needed up to 70 GPM.

Heat Pump Features Continued
EASY ACCESS
The heater was designed for quick and easy access for installation and
diagnosis. The service panel is removed with four screws and access
to all service connections are right up front and easy to reach. This
allows the installation and service to be done quickly and efficiently –
so valuable time is not wasted.
EVEN-HEAT (Additional wiring required)
the GPS feature. (page 15)
This feature allows the heater to periodically turn pool circulation pump
on and test water temp. If temp is below the set point programmed on
board, the heater will run the pool pump until it reaches set point, then
it will shut the unit and the circulation pump back off. This feature can
be set to run in one-hour increments. This feature is after paired with
SOLAR CONTROL (Additional wiring required)
The board can be set to run and monitor your pool solar system. There
is no need to have a second and separate control system. (page 8)
MOTORIZED VALVE CONTROL (Additional wiring required)
The Board now has terminals for your motorized valves; this will allow
your heater to switch the valve from pool to spa by just pressing the
“MODE” button. (page 9)
HEAT PUMP OPERATION
POWER OFF
In order to shut Heat pump off, press the “MODE” button until it reads,
“POWER OFF” , while in “POWER OFF” the unit will not run. To get out
of “POWER OFF” , press the “MODE” button, that will lead you to the
“POOL - HEAT” screen where you can continue normal operation. Solar
control will not operate in “OFF” mode.
CAUTION:
When the control is in the “OFF” mode, there is still high voltage to
the unit. If you want to turn the unit off for long periods of time,
shut the main power off to the unit at the main or service
disconnect.

12
POOL/SPA MODES
The control is equipped with two independent thermostats, one for
pool temperature and one for spa temperature. This is to allow user
to preset a temperature of their choice and switch between the two
settings with the “MODE” button located on the control. When water is
flowing through the unit and the water temperature meets the
specified set point condition, the control will turn off the heater.
If you do not have a spa, you can use the spa thermostat as a second
temperature setting if you do not want to maintain full temperature all
the time. For instance, if you swim on the weekends only, you can set
the temperature back during the week to save costs but maintain a
warmer temperature for a shorter recovery time for the weekend.
The display on the control will show the thermostat being used and the
operating mode on the top line and the current water temperature on
the bottom line. The Standard mode displays are:
“POOL – HEAT”, “SPA – HEAT”, ”POWER OFF”.
“POOL-COOL”, “POOL- HEAT/COOL”, “POOL SOLAR HEAT” will also be
available if enabled in the service menu. Addition programming and
wiring may be required for these features to be activated.
CHANGING SET POINT TEMPERATURE
To change the set point temperature, press either the “Up” or “Down”
arrow buttons on the control. The display will then show “POOL or SPA
TEMPERATURE SET POINT” on the top line and the current set point
temperature in numbers on the bottom line. After adjusting to the
desired temperature setting, the display will revert to “POOL or SPA –
HEAT” on the top line and the pool temperature in numbers with
“DEGREES” on the bottom line. After 5 seconds of inactivity and the
new set point will be stored in memory. The default factory setting for
Pool temperature is 85˚ Fahrenheit (F).
ATTENTION:
There is a 120 Second time delay upon initiation of a heating cycle.
This is to ensure that the critical components do not fail due to
short cycling of the heater. A count down will be provided on the
display.

13
HEATER RUNNING TIME
The owner is responsible for determining the necessary length of
operating time for the pump and heater based upon users particular
requirements. Most units are sized to operate during the pool filtering
cycle time of 8 to 10 hours daily, providing an even, steady flow of
heat. On warmer days the heater will run less because there will be
less heat loss from your pool. The heater is capable of running 24
hours per day if necessary. When you first run your heater, it may
need to run continuously for 24 to 48 hours to get the pool up to the
desired temperature. The heater operates most efficiently when
operated during the warmest hours of the day.
KEYPAD LOCKOUT
While in any mode the user can lockout the keypad by pressing and
holding the “MODE ” button for 6 seconds. When the keypad “LOCKED”
has been enabled all buttons are disabled and the control will operate
in whatever mode it was in when the lockout occurred. Any button
push while in “LOCKED” will cause the display to show “LOCKED” for 5
seconds. To unlock the Keypad, press and hold the “MODE” button for
6 seconds. The display will show “UNLOCKED” for 5 seconds.
DEFROST CYCLE
The heater is designed to enter the defrost cycle at ambient air
temperatures below 48˚ Fahrenheit. During this cycle, the unit may
shut down and the control will display “DEFROSTING” until the ambient
air temperature rises above frosting conditions. Hot Gas Defrost in
certain models is available – Allows unit to operate in the mid 30’s˚F.
This feature must be enabled in the service menu. Unit will not operate
below 35˚F.
CONDENSATE DRAINAGE
It is normal for water to be draining from your heater. This occurs
because the evaporator coil condenses the water from the air. The
water drains into the base of the unit and out the holes that are located
on each side of the heater at the bottom. Your heater can produce
up to 3 gallons of water per hour. The water created from the
condensation will dry up when the heater is shut off.

14
POOL SOLAR HEAT OPERATION
Once the Solar Control is enabled in the Hidden Menu, and 20
seconds of inactivity, the Screen will return to display “POOL–HEAT ”

CARE & MAINTENANCE
CLEANING
There is not much maintenance that needs to be done on your heater.
Making sure there is good airflow through the evaporator and proper
drainage are the two main tasks. A garden hose with low-pressure
water flow can be used to clean the evaporator coil, DO NOT spray the
control box. Keep all shrubs trimmed back away from the unit to allow
sufficient airflow. Clean the coil as needed. If located near the ocean,
cleaning will need to be done regularly to remove salt and sand. Use
a very soft brush so as not to bend the coil fins with soapy water to
remove any build up.
Keep the drain holes in the base free of debris to assure proper
condensation drainage.
Your heat pump’s cabinet is made from a maintenance-free, rust-free
plastic that is UV-resistant. It will last for years and any dirt or dust
may be wiped away with a cloth or sprayed off with a water hose. Only
use products designed for cleaning plastics.
WINTERIZING
In areas where freezing condition is not prevalent and winterizing of
pools is not common, allow water to flow through the heater even
when not in use.
CAUTION:
Make sure all power is disconnected to the heater prior to washing.
WARNING:
DO NOT USE CLEANERS THAT CONTAIN ALCOHOL.
Alcohol based cleaners may damage the plastic.
ATTENTION:
In freezing areas, it is MANDATORY that the water be
completely drained from the heater and disconnected from
the piping. The heat exchanger must be blown out with air
to ensure no water is left in the heat exchanger.

17
TROULESHOOTING
A simple test to verify that your heater is functioning is to place your
hand above the unit. There should be cool air blowing out the top after
time delay has expired. The return water to the pool should be a few
degrees warmer than water entering the heater. After about 15
minutes of run time, there should be water draining out of the base of
the unit. If you have reason to believe your heater is not functioning
properly, follow the troubleshooting guide below, If the unit is still
having issues, please call for service.
Unit has a blank display:
Check Breakers, Disconnect or Transformer
Try to reset the breaker by flipping it off and then back on, if
you still do not get display on board, you may need to have an
electrician to make sure the breaker or transformer is still in
working condition.
Unit has water coming out of bottom of unit:
Turn the Heater off, but allow the Pool Pump to continue to run.
Come back after about 1 hour, if the water stopped coming
out of bottom of unit, it is normal condensation.
If water still coming out of the bottom of the unit, then you
may have a water leak inside of the unit. Also, a pool test strip
can detect chlorine if a water leak is suspected.
Heater is heating slowly or not getting up to temperature:
Low or restricted water flow through the heater
You may need to clean or replace the filter.
Check the pool pump to make sure you are getting about 40-
50 GPM through the unit. Variable speed pumps should
provide 40-50 GPM (rpm’s will vary between brand –
commonly we see 2400 rpm as sufficient)
Air leak in pool system
Repair any air leaks in plumbing
Pool Pump Run Time
Make sure you are allowing the pool pump to run long enough,
try to allow unit to run longer.
Strong winds in pool area
This may cause water to lose a large portion of heat from the
wind. Install some type of windbreak around the pool
Use of a pool blanket will greatly cut down the amount of heat
loss you experience and save you money.
I see a countdown on my display and my unit is not kicking on:
Delay is a 2-minute waiting period to allow the unit pressures to
balance out. Once the count-down reaches zero, the unit should kick
on. If not, the unit may require a new contactor.

18
Unit Displays No Flow or Water Flow HP:
Check to make sure the Pool Pump is on and primed
If pump is off, or not primed it will not send any water through
the system.
Check any bypass valves
Make sure they are not redirecting the water away from the
unit you want to make sure that you are getting anywhere
from 30 GPM to 70 GPM through the unit.
Check the pool filter to make sure it is clean
If filter is dirty then the unit will not receive the correct
amount of water. Make sure that the filter is being cleaned or
replaced when is necessary.
Unit Displays Water Flow Lockout:
Once the unit has had a Water Flow HP 3 times the unit will lockout
Check the same flow issues for No Flow and Water Flow HP
Backflow from solar or pool heater below water level
Water backflow once the circulation pump stops can activate
the pressure switch. Adjust pressure switch as needed or
install a flow switch.
If flow issues have been addressed the hold the down arrow
for 5 seconds to reset the lockout.
Unit Displays Low Refrigerant Pressure:
Unit low-pressure switch was activated
Call For service.
Unit Displays Max Water Temperature:
Check to make sure you do not have a secondary source of heat
feeding hot water into the unit
If no secondary source of heat call for service.
Unit Displays Water/ Evap Sensor Malfunction:
Unit Water or Evaporator Sensor needs service
Call for Service.
Unit Displays Solar Sensor Malfunction:
Check to see if you have a solar system.
If so, then you need to have the sensor on the roof serviced.
If not, then someone has enabled this feature in your board.
Load Defaults or Call Office for Service.
Unit Displays Even Heat Lockout:
Even Heat is a feature the requires additional wiring and installation of
a secondary contactor
If you have a the Even Heat Feature, the signal has an
interruption and needs to be checked out prior to having
service on the heater.
If not, then someone has enabled this feature in your board.
Call Office for Service.
Unit is Making a Loud Noise:
Check to see if the sound stops after running for a few minutes.
If it stops making noise after while it may be because of the
starting position of the compressor. This can occur sometimes,
may not need service as long as it corrects itself.
Look to see if the fan is hitting anything.
If noise does not stop call office for Service.
