IMPORTANT SAFETY RULES
Horizon Ventures PO Box 513, Deerfield, IL 60015
www.horizonreels.net [email protected]

•Carefully read and adhere to all CAUTION and NOTE notices located throughout this
manual. Failure to comply with these instructions can cause personal injury or damage to
the unit.
• Do NOT allow children to operate this Product.
•Always turn the filter system off when installing or working on the sunCOIL.
•Install this product away from the pool to prevent children from using the sunCOIL as a
way to access the pool.
• NEVER service this unit with the pool pump running.
•Do not use any petroleum based lubricant. Petroleum based products will destroy plastic
parts. Use silicone lubricants only.
•The sunCOIL is to be installed between the Filter and the pool water return fitting, AFTER
the water is filtered The sunCOIL must come after the Filter to prevent dirt & debris from
cloging the hose of the sunCOIL.
•Before loosening any threaded connections on filter, pump or pool, be sure the return
fitting & skimmer are closed or blocked at the pool to prevent water flowing out of the pool.
The sunCOIL you just purchased for your aboveground pool is simple to install and effortless to
operate once connected. The installation instructions included in this manual are based on a few
assumptions:
1) you have an existing above ground pool that is completely set up and filled with water,
2) your above ground pool is equipped with a pump-operated water filtering system, and
3) you have the necessary hoses needed to feed water in and out of your pool and filter system.
！WARNING
GENERAL INFORMATION
These assumptions are necessary as the sunCOIL(s), once installed, will be completely dependent upon
your pool’s filter pump to push water in and through the heater’s solar coils.
How It Works
When properly installed, the sunCOIL will be connected to your filter and your pool by two hose
connections: One hose will feed cold, filtered pool water from your filter system into one port of the
sunCOIL.The other hose will return sun-warmed water from the other port of the sunCOIL to your pool via
the pool return fitting in your pool.
As cold water is fed into the sunCOIL, it travels through the solar coils where it is heated by the sun before it is
delivered back into your swimming pool.
Know Your Pool
Before you begin installation it is a good idea to know certain specifications of your pool:
How big is your pool?
How many gallons does it hold?
What size hose does it use? (i.e.1¼” dia or 1½” dia) (USE THE BLACK HOSE)
How big is your Filter Pump?
sunCOIL can be used on Filter Pumps from 1/4 (.25) H.P up to 1 1/2 (1.50) H.P only.
Do not use sunCOIL on pumps over 1 1/2 (1.50) H.P.
sunCOIL Location
Your sunCOIL needs to be located on a hard level surface. You will need to position the heater
lower than the pool's water level and at a safe distance away from the pool.
Your sunCOIL must be positioned for maximum exposure to the sun. PAGE 2

STEP 2: INSTALLATION INSTRUCTIONS - OVERVIEW
sunCOIL – Filter – Pool Layout
The system layouts below will help you install the sunCOIL(S) to your aboveground pool.
NOTE: The connections in Fig. 3 & 4 show the water flowing into the sunCOIL through
the side connector and out through the center connector located on the underside of the
sunCOIL. This diagram is for reference only as the flow may be reversed if you choose.
The FLOW REDUCER must put into the elbow closest to the filter.
The sunCOIL must be intalled with Diverter Valve Kit. Operating the filter system
withouth a Diverter Valve Kit in place might cause damage to filter, pump and sunCOIL.

WARNING: In order to use other outlet water features such as fountains,
the solarDOME's Diverter Valve must be in the Bypass mode (Positon 3) !

NOTE: Turn off the pool pump before connecting the sunCOIL. Block water flow at the Pool
Return & Skimmer.
WARNING: The Flow Reducer must be installed on the filter side of the sunCOIL.
(When more than one sunCOIL is connected, the Flow Reducer must be installed in the sunCOIL
on the side that is the nearest to the Filter. There is no need to install a Flow Reducer on the other
solarDOMES.) Installing the Flow Reducer properly will put less water pressure on the sunCOIL &
extend it's service life.
Reminder: Do not forget to unblock the Pool Return & Skimmer before turning on the pump.
sunCOIL - Pool Connections
1. Filter to Diverter Valve Connection
A. Wrap the threads of the 3 Hose Adaptors
with Teflon tape (provided). Twist these
adaptors into the 3 ports at the Diverter Valve
B. Position the Diverter Valve exactly as shown
in the diagram on Page 4 (see Fig 3).
The valve must be installed correctly for the
sunCOIL to work. Failure to position the Valve
correctly will reduce the sunCOIL 's ability to
heat the pool water.
C. After blocking the return fitting & Skimmer at
the pool to prevent water from flowing out of
the pool, remove the hose at the pool wall that
runs from the Filter System to the return fitting.
D. Connect this hose to the common port of
the Diverter Valve (at Position 4) & secure with
a stainless steel clamp.
2.Diverter Valve to sunCOIL Connections
A. Put the orange Flow Reducer into the
Elbow Connecter to be installed where clean
water from the Filter System enters the
sunCOIL.
B. If you are using the 1 1/2" diameter black
hose (provided), you must place the 1 1/4" - 1
1/2" rubber Elbow Sleeve on the Elbow
Connector. (If using 1 1/4" diameter hose the
Elbow Sleeve is not required.)
C. Put the hose on the Elbow Connector &
secure it with a stainless steel hose clamp.
(If necessary the provided hoses may be cut at
the cuff.)
D. Apply a small amount of silicone lubricant to
the O-ring & put the O-ring in the grove on the
short side of the Elbow Connector.
E. Insert the Elbow Connector into a port on
the underside of the sunCOIL & twist to lock it
in place.
F. Connect a hose from the Elbow to the
Diverter Valve (see Fig. 3 & 4).

TROUBLESHOOTING
Issue Possibilities / Solutions
Does not appear to
be heating the pool
Check to make sure water is flowing through the tubes. Check the flow
strength at the pool inlet.
Has it been sunny? Addtional sunCOIL(s) may be needed.
There could be a clog in the tubing. Try to purge out the clog
Leaking heater Check the connection seals and replace or repair if defective.
Bubbles continue to flow
out of the pool water
inlet well after the pump
has been turned on
Check the connections for a suction leak.
There could be a break in the tubing.
There could be a clog in the tubing.
Try to purge out the clog.
Check to make sure the flow rate is normal.

3."T" Connector Installation
A. The "T" Connector must be positioned exactly as shown in Figures 3 & 4. Failure to position the "T"
Connector correctly will reduce the effectiveness of the sunCOIL.
B. Attach the second Elbow Connector to the remaining port on the underside of the sunCOIL in the same
way as the first Elbow Connector. No Flow Reducer is used here.
C. Attach a hose from the Elbow to the "T" Connector & secure the hose at both ends with stainless steel
hose clamps.
D. Attach a hose from the Diverter Valve to the "T" Connector & secure both ends with a stainless steel hose
clamp.
E. Attach a hose from the "T" Connector to the return fitting on the pool wall and secure the hose at both
ends with a stainless steel hose clamp.
F. Unblock the Skimmer & Return Fitting & allow water to flow into the system.
Check for leaks & tighten the hose clamps if necessary.
How to use the Diverter Valve (see Fig. 7)
4.
Do not use sunCOIL on a Pump larger than 1 1/2
(1.5) H.P. This will overload the sunCOIL and
cause damage.
A. Position the Nose on the front of the Diverter Valve
Handle to the correct Position Number below based on
the size of your pump.
B. To BYPASS the sunCOIL & divert all water
directly back to the Pool, place the Nose of the
Valve Handle in "Position 3".
Pumps 1/4 (.25) H.P. - Use Position 1:
Directs all water to sunCOIL. (Only used by small pumps.)
Using any other positions on this size pump will not heat water.
Pumps 3/4 (.75) up to 1 1/2 (1.5) H.P. - Use Position 2:
Directs 1/2 water through sunCOIL & 1/2 to bypass.
Bypass - Use Position 3:
All water bypasses sunCOIL an no heating takes place. Use when
no heating is required. You may use other water features when
Diverter Valve is in Position 3.
Not Used - Position 4: This position is never used.
Using this position will damage Pump and Filter.
Pumps 1/2 (.5) H.P. - Use Position 5:
Directs 3/4 of water through sunCOIL & 1/4 is bypassed.
