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.

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.

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.

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.
