Plumbing up the system:
This system will work if the pump draws or discharges water through the heater. Minimum water flow required is 25 GPM. Minimum
plumbing size required is 1.5 inch. This system is equipped with M7 Technology (no pressure switch). There are dual sensors installed
on the heater to measure the water temperature flowing through the heater. No need to mount any sensors or flow switches. The heater has
standard 2.0 inch plumbing fittings. If the spa plumbing is 1.5 inch, use reducers to connect to the heater 2.0 inch heater tailpieces. If re
plumbing is necessary, use PVC Glue with primer to connect the plumbing. When installing an In Line Filter System, either install it
before the heat pump and controller or after the heat pump and controller. Never install the filter system in between the heat pump and
controller. Make sure to create a water flow bypass plumbing around the filter for sufficient water flow. For systems installed near or
above the water level, and more than 5 feet from the tub, install the In Line Filter System after the heat pump and controller with a water
flow bypass plumbing. A water flow bypass plumbing allows half the water to go through the filter and half the water to go around the
filter. This way water flow is not restricted. We recommend NSF rated flexible PVC for simpler connections. Go to this link for more

Wiring Instructions:
*220V Power Supply, 60Hz
*Minimum 60A Power Supply is required. Use Copper Conductors Only. See wiring diagram for more information.
Please note that this Installation requires 4 dedicated wire connections to the power terminal block (TB1) on the Circuit Board. These
include Line 1, Line 2, Neutral and Ground. Connect Line 1 wire to Line 1 terminal. Connect Line 2 wire to Line 2 terminal. Connect
Neutral wire to Neutral terminal. If a dedicated Neutral wire is not connected, the heater will never come on and/or the system will not
operate properly. Lastly, connect Ground to the Grounding Bar located on the side of the controller box. Since this system is not equipped
with a GFCI, it is REQUIRED by the National Electric Code to install an external GFCI for safety and protection. Any mis wiring or
improper installation will void the warranty and could cause personal injury, death, fire or property damage.
Do Not follow the color of the original power wires, Black, Red, White and Green. DON'T ASSUME THESE WIRES ARE WIRED
ACCORDING TO LOCAL CODES. Some original wirings can have the wires mixed up. Get a voltage meter and verify each wire to
make sure which colored wire is Line 1, Neutral, and Ground. Failure to do so will cause major electrical damage to the controller and/or
other equipment, and void the warranty.
DO NOT POWER UP THE SPA UNLESS THE SYSTEM IS COMPLETELY INSTALLED AND THE SPA IS COMPLETELY FILLED
UP WITH WATER. Doing so can cause a dry fire, which can damage the heater and controller, and will void the warranty.

Circulation Pump Circuit: This system is not setup to operate a circulation pump as the heat pump (unless it was specified over the
phone at the time of order). If a small circulation pump is connected to the system and being used as the heat pump, make sure to follow
the wiring diagram to setup the correct voltage output for the circulation pump. Also setup the dip switches on the circuit board so that the
system works properly with the circulation pump. Minimum water flow is 25 GPM with minimum 1.5 inch plumbing. This system
will NOT work with a Low- lo Circulation Pump.
Circulation Pump wiring: The circulation pump cord will have 3 wires (cord is not included, sold separately). The Black wire is for Line
1. The White wire is for Common connection, and the Green wire is for ground. Connect the circulation pump cord in the Circulation
Pump location (J47) on the circuit board. The plug will only fit one way. Make sure the clip on the plug latches to ensure tight connection.
Only connect the circulation pump cord if it is being used. (See notes above regard the circulation pump circuit and using a
circulation pump with this system)
Dip Switch Settings: The dip switches on the circuit board (as known as Switch Bank A, red in color with white switches) should have
already been configured for the correct setting based on your order. If a different setup is made in the field and/or a circulation pump is
added, the dip switches need to be reconfigured. If so, please follow the dip switch settings based on the new setup by using the wiring
diagram as a reference.
Topside Panel Installation: A hole cut out of 8.5 inch x 2.375 inch is required for the SpaGuts Topside Panel, P/N 50286. A topside cover
plate (not included) can be used if the existing hole cut out is larger than the topside panel. Clean the surface area before installation of the
new topside panel. Position the topside panel in the direction for operational purpose as desired. Then carefully insert the topside cable
through the hole cut out. Remove the protective label from the sticky gasket on the back of the topside panel. Then apply the topside
panel above the hole cut out or cover plate. Silicone can be used under the lip of the topside panel for additional water leak protection
prior to installation of the topside panel. Connect the topside cable plug into J1 connector on the circuit board. The clip on the topside
cable plug should snap in place to ensure a secure connection. The J2 connector is for an auxiliary topside panel, which can be purchased
separately. If a longer topside cable is needed, DO NOT splice the cable or disconnect the cable from the back of the topside panel to
install a longer cable. Doing so will affect the proper functionality of the topside panel and completely void the topside warranty.
Available at www.spaguts.com is P/N 30311 for the 10ft extension cable, and P/N 22639 for the 25ft extension cable. Maximum cable
length is 50ft in order for the topside panel to work properly.
Light wiring: The light harness is 8ft long with 2 wires. One end of the light harness has a 2 prong amp plug, and the other end has a
light socket that fits a 12V 12W light bulb or a ColorGlo Led Light (http://www.spaguts.com/Products/colorglo led lights 47.aspx).
Connect the 2 prong amp plug in location (J20) on the circuit board. The plug will only fit one way. Make sure the clip on the plug latches
to ensure tight connection. Insert the light bulb into the light socket. Then insert the light socket with light bulb into the existing light
housing on the spa. The white light reflector can also be used if it fits in the existing light housing. If a light housing is not installed, it can
be purchased by going to this link: http://www.spaguts.com/Products/thru shell light lense kit 88.aspx. Only connect the light harness if it
is being used.
Audio Video wiring (A/V): The A/V circuit is normally setup for 110V (unless it was specified over the phone at the time of order for
220V output). This circuit is a constant voltage output normally used for a stereo, radio, CD or TV systems. The A/V cord will have 3
wires (cord is not included, sold separately). The Black wire is for Line 1. The White wire is for Common connection, and the Green wire
is for ground. Connect the A/V cord in the A/V location (J50) on the circuit board. The plug will only fit one way. Make sure the clip on
the plug latches to ensure tight connection. Only connect the A/V cord if it is being used.
DO NOT POWER UP THE SPA UNLESS THE SYSTEM IS COMPLETELY INSTALLED AND THE SPA IS COMPLETELY
ILLED UP WITH WATER. Doing so can cause a dry fire, which can damage the heater and controller, and will void the
warranty.
After installation is complete, completely fill the spa with water to the required level. Refer to the Spa Owners Manual for the required
water level. We recommend using the “Pure Fill Spa Pre Filter” for fresh clean water. DO NOT OVERFILL. Overflowing the spa will
cause water to infiltrate the system and other electrical parts. Damages caused by water infiltration will not be covered under warranty.
Once the spa is completely filled to the required level, then power up the spa and purge the water lines to help remove air from the lines.
The “Pr” message will appear on the topside panel which indicates water purging is required or is in progress. If the pump is not running,
press on the Jets key to activate the pump on high speed. You may also bleed air out of the plumbing by loosening the plumbing fittings a
bit, and then run the pump high speed on/off until all the air is out. Once there is constant strong water pressure from the jets, you can
now proceed with normal operations. Make sure all plumbing fittings are tighten and to fix any leak.
System Maintenance: It is recommended to monitor the spa equipment every month. Check out for water leaks, internally and externally,
and for abnormal operations. Get it repaired right away if there is a problem. Don't allow the problem to get worst. It is recommended to
inspect for any loose connections and for any damaged cables every 3 6 months (especially on the power terminal block, component cord,
and sensors). Loose connections will cause improper operation and overheat the wires. Damaged cables are mostly cause by rodents.

Spa Maintenance: Refer to the Spaaaahhhhhh: Owners Guide to Hot Tubs (http://www.spaguts.com/Products/spaaaahhhhhh owners
guide to hot tubs 10.aspx) for proper water maintenance. Use ONLY Spa rated chemicals. We recommend using ozone, Mineral
Cartridges and a small amount of chemical to treat the water. Ozone and Mineral Cartridges reduces maintenance and decreases the use of
chemicals up to 90%. We also recommend to test the spa water every single day, and treat the spa water as needed.
