HELIOCOL RESIDENTIAL INSTALLATION MANUAL 2
INTRODUCTION
Heliocol solar collectors are manufactured utilizing state-of-the-art solar technology and the
most advanced production techniques. Heliocol collectors are sleek and simple, yet the patented
over-molded design makes Heliocol durable enough to last a lifetime. However, a professional
installation is very important to the overall success of a system. Installed properly, a Heliocol
System will be virtually maintenance free as it captures free, abundant, and reliable energy from
the sun year after year.
Take time to read through this manual. It will guide you through the most ecient way to
correctly install a Heliocol solar system. By following this step-by-step guide, your system will
meet the installation standards recommended by the factory (see disclaimer on front page). In
addition, because we have included techniques and tips gathered from experienced Heliocol
contractors throughout the country, using this installation will save you time and eort.
PRE-INSTALLATION NOTES
BEFORE YOU START YOUR INSTALLATION, HERE ARE A FEW IMPORTANT TIPS:
1. CAUTION: SAFETY COMES FIRST! There is no substitute for safety. Always exercise extreme
caution, care, and good judgment when working on or around the roof and/or pool.
•Please take care to avoid hazards such as overhead electrical wires or loose shingles.
•Be sure to secure ladders so they will not slip or fall.
•Wear shoes with proper tread to prevent slipping on the ladder or sloped roof areas.
•We recommend utilizing fall-protection equipment whenever working on a roof.
(Refer to OSHA for requirements.)
•Do not allow extension cords to lie in the pool or in standing water.
•Disconnect all power to the pool equipment when installing an automatic control system.
2. Check with your local building department to determine permitting and code
requirements in your area. A licensed engineer may need to provide plans
for the installation of Heliocol collectors.

PRE-INSTALLATION NOTES (CONTINUED)
3. While this manual explains how to install Heliocol solar collectors properly in typical
situations, it cannot possibly address all the unique or individual circumstances possible. If
you have any installation questions, contact your Heliocol representative for assistance.
4. Before starting any work, determine the location of your system and prepare a schematic
drawing of the installation area. Include the location of the feed and the return lines in this
drawing. Roof areas often appear larger than they really are, so be sure to measure the
available area before making your schematic. Be sure that the layout of the collectors will
allow the collectors to automatically drain when the pool pump shuts o.
5. Familiarize yourself with all the Heliocol components and
plumbing materials that you will need to complete the installation.
6. Do not take shortcuts. Whenever possible, collectors should be installed so they are accessible
without being walked on. Walking on the collectors should only take place when necessary.
7. Depending upon your specic job, you will need various plumbing items and materials.
Be sure to use quality products that will withstand direct sunlight year after year. All
components should meet minimum standards set forth by the local building code.
•PVC Pipe - Use PVC Schedule 40 or 80 pressure-rated pipe (Conforming to ASTM D 1785).
CPVC pipe is allowable. Do not use ABS pipe or metallic piping.
• PVC Fittings - Use PVC pressure-rated ttings to match your PVC pipe (Conforming to
ASTM D 2466). DO NOT USE - “Plumber’s” ttings or DWV ttings (drain, waste, vent).
•PVC Cleaner and Cement - It is important to both clean and cement each PVC joint.
When gluing CPVC ttings to PVC pipe, such as the CPVC pipe connector, it is necessary
to use a “multi-purpose” cement designed for use on both PVC & CPVC components.
Standard cement used for PVC joints will not work for CPVC ttings or pipe.

SYSTEM DESIGN & SIZING
For pool heating applications the design and sizing of systems is relatively simple and
is a function of several factors including pool size, location, and orientation. What follows
is a walkthrough of the design and sizing process for solar pool heating systems.
SYSTEM SIZING
For most pool heating applications, the optimal system size will be 75-100% of the pool surface
area. This can be achieved using one or multiple collector sizes and will vary based on usage,
location, and roof orientation, among other things. The optimal system size must be balanced
with the available roof area and ow rate through the pool’s ltration system.
Systems larger than 100% of the pool’s surface area may be required for optimal heating for
pools that are heavily shaded or indoors. Systems smaller than 75% will still add heat to the
pool but may not function as well as system closer to the size of the pool.
ROOF ASPECTS
Host roofs used for mounting solar pool heating systems must simultaneously be large
enough, strong enough, and oriented in a way that will facilitate the best performance
possible. Ideally, collectors should be located on a south-facing, pitched roof. Western and
eastern orientations are also acceptable with east-facing systems producing more in the
morning and west-facing systems the afternoon. Collectors should never be installed facing
north in the northern hemisphere.
Most residential roofs are perfectly capable of supporting solar pool heating systems and the
water that runs through them. At minimum, a roof is normally built to withstand a 20 PSF live
load (for people walking on a roof) and Heliocol systems only exert a 1 PSF gravity load while
operating.
When deciding on a location for the solar pool heating system the roof area must be large
enough for the collectors, mounting hardware, and piping while still allowing for proper
setbacks from ridges, valleys, edges, and vents. Proper planning is critical to make sure
the roof area is suciently larger enough for the system being installed.
Installations on low-slope roofs and ground-based structures are also allowable but require
special consideration. In these cases, please contact your Heliocol representative for assistance.

COLLECTOR CONFIGURATIONS
There are many ways to congure a solar pool heating system using Heliocol collectors. The
most common and preferred method is in a single, continuous row, or bank of collectors.
Bank sizing is limited by the size and quantity of Heliocol collectors used to achieve even ow
throughout the bank. This is based on an ideal, maximum ow rate of 40 GPM to any bank of
collectors. Below is a table displaying each model of Heliocol collector and the maximum bank
size. (See Table 1)
Banks of collectors may exceed the maximum limit provided so long as adequate pumping
power and a means of ow balancing (ball valves) exist within the solar loop. The maximum
bank sizes should never be exceeded by more than (2) collectors for pool heating applications.

SYSTEM DESIGN & SIZING (CONTINUED)
For larger systems or where the roof design presents a challenge multiple banks may be used.
For more information on this please see the section Collector Layout & Plumbing later in this
manual. Roof obstacles like vents, stacks, or skylights may also require multiple banks to be
used. In certain situations, banks may be separated but still connected as a single bank to get
around these obstacles. For more information on this please see the section Roof Obstacles
later in this manual.
SYSTEM PLUMBING
It is critical that you use the proper size piping for the size of the solar pool heating system.
Under sizing the pipe will cause high amounts friction head loss leading to low ow rates,
more load on the pump, and reduced pool performance from the solar pool heating system.
Below (Table 3) lists out total system ow rates and the minimum Sch. 40 PVC pipe size to use.
For larger systems, the main supply and return piping may be larger than the piping
directly connected to each bank on collectors. It is recommended that 2” Sch. 40 PVC
be used to connect directly to the collector banks.
Plumbing runs should be as short as possible and the return pipe to the pool should have the
shortest run to reduce the potential heat loss. Horizontal pipes should be supported with a pipe
clamp at least every 4 ft. to prevent sagging or “snaking”. Piping runs should always be designed
to handle thermal deformation (expansion and contraction) and pipe supports used must allow
for this. Pipe supports used to secure piping to a wall should be installed every 10’ at minimum.

HELIOCOL RESIDENTIAL INSTALLATION MANUAL 9
SYSTEM DESIGN & SIZING (CONTINUED)
PUMP & FLOW RATE
Many solar pool heating systems will employ the existing pool ltration pump to supply ow to
the solar collectors via a manual or motorized diverter valve. In these congurations the water
will ow through the solar collectors after exiting the lter before returning to the pool instead
of going to the pool directly. It is important that the pump have enough power to produce
adequate ow to solar pool heating system while maintaining the required turnover for health
and safety purposes. A solar pool heating system is an additional load on the pump and must be
factored in when designing the system.
The optimal ow rate for the solar pool heating system is a function of the size & quantity of
collectors being installed and how they will be plumbed. This ow rate should be compared to
the existing ltration system ow rate and should be equal to, or less than, the pool’s current
ow rate. If the ow rate is greater than the pool’s current ow rate, then series-parallel
plumbing or alternate connection to the pool may be employed. For more information see the
sections The Solar Collector and Collector Layout & Plumbing later in this manual.
AUTOMATIC DRAINDOWN & FREEZE PROTECTION
The collectors & piping should be installed in a manner that allows them to drain down by
gravity when the pool pump shuts o. This is especially important in areas of the country where
freezing conditions occur.
Like most plumbing components, Heliocol collectors will be damaged if water is left to freeze
inside them. While Heliocol collectors can handle freezing temperatures they cannot withstand,
nor are they warrantied against, water freezing within them. If, as a result of a unique roof
design or adverse pool equipment locations, it is not possible to achieve complete automatic
draindown, manual drain down valves should be installed in appropriate places in the plumbing
or at the end of the bottom (feed) manifold. These valves should be opened when shutting
down the system for the winter months or when freezing conditions are possible. Your Heliocol
representative can assist you with the parts necessary for manual draindown installations. Water
should never be trapped anywhere in the solar pool heating system when not in operation.

HELIOCOL RESIDENTIAL INSTALLATION MANUAL 10
THE SOLAR COLLECTOR
Heliocol collectors are comprised of two manifolds overmolded onto a quantity of separate riser
tubes held in place by spacer bars on the underside of the collector. Each riser tube represents
a full ow path for water from one manifold to the other. As a nished unit Heliocol collectors
have the ability to accept and heat a large volume of water eciently with very little head loss.
Heliocol collectors are light and durable with functional lifespans exceeding (15) years in many
cases. The open riser tube design allows wind to pass through the collectors which reduces
wind loads imposed on the roof and how many anchor points are required to penetrate the
roof. Collectors can be mounted on pitched and low-slope roofs as well as on ground-based
structures oering a large amount of exibility with system design. Proprietary mounting
hardware is used to mount the collectors to a variety of roof types and other structures.
Heliocol collectors come in a variety of sizes and are congured into one or multiple collector
banks to form a solar pool heating system. The size, quantity, and arrangement of the collectors
is used to determine the proper ow rate for the system. The optimal ow rate through any
collector is based on 0.1 GPM/ft2of collector area.

HELIOCOL RESIDENTIAL INSTALLATION MANUAL 14
COLLECTOR LAYOUT & PLUMBING
Collectors can be installed in a multitude of congurations and methods,
but systems should adhere to a few key rules for optimal performance.
1. Systems that are pitched should be installed with the feed line(s) entering the collector bank(s)
on the lower manifold and the return lines exiting the banks(s) on the opposite, upper
manifold end. Systems that are on low slope roofs or otherwise “at” surfaces may should
still ensure that the feed and return on are opposite manifold ends from each other.
2. Systems should be plumbed in a reverse-return fashion whenever possible. This means
that the return to the pool occurs as high up and/or as far away from the feed as possible
to ensure even, full ow through the system. If reverse-return plumbing is not feasible it
is important to use balancing valves through the system to ensure balanced ow to all
collectors and avoid short-circuiting any point in the system.
3. Systems should always have a means to drain down from the roof, preferably automatically
by gravity when the pump shuts o. For systems that cannot automatically drain a means of
manual drainage should be installed as required. Never create a situation where water can
be trapped in the system. Large diameter piping (2” and above) will drain even if perfectly
horizontal so there is no need to further slope horizontal piping runs.
4. Vacuum relief valves should be installed on all systems to facilitate proper drainage.
Vacuum relief valves allow air into the system as water exits to equalize pressure with
the atmosphere. The valves may be placed on the supply line at least 6 ft. above the pool
equipment or near the top of the system at the collectors. Failure to install vacuum relief
valves can cause damage to due freezing water and/or collapsed piping.

CONNECTING COLLECTORS TOGETHER
1. Place two collectors next to each other. The spacer bars that hold the individual
riser tubes together should be facing down. Lay a plastic collector clamp top,
bottom, gasket, and latch where the two manifolds meet. (Fig. 3-A)
2. Clean the groove of both manifolds.
3. Spray the gasket with silicone and insert it into the groove of one of the manifolds.
Make sure that the gasket is fully seated into the manifold groove by pushing rmly
with your thumb all the way around the gasket. (Fig. 3-B)
4. Place the bottom half of the plastic collector clamp under the collector manifold
with the hook portion of the collector clamp facing toward the riser tubes. (Fig. 3-C)

CONNECTING COLLECTORS TOGETHER (CONTINUED)
5. Seat both manifolds together by inserting the gasket into the opposite manifold groove and
placing the ends of both manifolds into the open space in the collector clamp bottom. (Fig. 3-D)
6. Interlock the top half of the collector clamp with the hook on the bottom half. Swing top half
over top of collector manifolds. Squeeze the top and bottom portions of the collector clamp
together using channel lock pliers and lock both halves of the clamp together using the latch.
(Fig. 3 - E & F)
NOTE: Slide large end of locking clip over small end of plastic collector clamp assembly.
7. Use channel lock pliers to tighten the clip grip by squeezing it with reasonable force
until it seats ush or even slightly farther so it cannot slide out of its position. (Fig. 3-G)
8. Insert locking clip into slots on latch. (Fig. 3-H)
9. Use this same procedure to connect both top and bottom manifolds of the collectors.

COLLECTOR ROOF MOUNTING – SHINGLE ROOFS
NOTE: A secure, permanent connection to the roof is important to the performance and
longevity of the Heliocol system. Even more important, however, is to ensure no harm is done
to the structural integrity or weatherproong of the host roof. It is highly recommended that
approved roof sealants and ashings be used when making any roof penetrations.

COLLECTOR ROOF MOUNTING – SHINGLE ROOFS
(CONTINUED)
The vast majority of residential roong in the US is asphalt shingle roong. For the purposes
of this manual only installations for asphalt shingle roofs will be detailed in depth.
1. Snap a chalk line across the roof or rack where you
want the top edge of the collectors to be located.
2. Locate and mark the locations of the roof trusses along the rst chalk line made.
3. Position the rst Top Gator Clamp on the chalk line and centered over a roof truss.
No matter the truss location a minimum of (2) mounts are required at the top and bottom
manifold of each collector (four in total).
4. Subsequent Top Gator Clamps should be spaced out evenly along the chalk line
where roof trusses occur. Each Top Gator Clamp can be located anywhere along the top
manifold to match up to the spacing of the roof trusses as long as there is a 2” space between
the edge of the Top Gator Clamp and the ribs on the collector manifold that exist every one
foot. This allows for horizontal expansion and contraction (thermal deformation).
5. Direct mounting application:
NOTE: While direct mounting Gator Clamps to the roof has been common practice
and is a structurally sound method of mounting it does create a risk for roof leaks
if not done perfectly. Current building codes call for all roof penetrations to be
sealed & ashed using approved products. If ashings are required, then skip
to Step 6 detailing the use of RoofTech RT-Mini Mounts.
a. Apply ample sealant to both the bottom and top of the anchor hole on the bottom
portion of the Gator Clamp. (Fig. 5-A). Position the bottom portion of the Gator Clamp
perpendicular to the chalk line with the lower hole being placed right on the chalk line.
Anchor the Gator Clamp to the roof through the lower hole using a 1/4” lag bolt. The
length of the lag bolt used is based on how much embedment into the truss is required.
Typically, this is 2” of embedment but the engineering plans will specify this.
b. The bottom of the Gator Clamp is designed to grip the roof’s surface to avoid rotation
back and forth. A second hole is present if more than one anchor bolt is required.
