introduction

OVSOL System

This manual provides installation instructions for OVSOL System for solar domestic hot water heating. The OVSOL solar energy system described in this manual, when properly installed and maintained, meets the minimum standards established by the SRCC.

This certication does not imply endorsement or warranty of this product by the SRCC.

Planning before the installation and use of the solar collector array should include:

l Solar hot water system design.

l Properly sized solar storage tank.

l Properly sized and insulated solar loop (plumbing circuit).

l An air bleed valve at the highest point in the collector circuit located for convenient access.

l Roof penetrations for piping to and from the collector.

l System components for closed loop solar systems—tank, heat exchanger, solar loop circulator,

pressure relief valve, solar controller, expansion tank, ll and drain valves, pressure and temperature

gauges.

l Propylene glycol (antifreeze) to provide protection from frost and high idle mode temperatures of

375 °F.

Requirements for each installation should be fully detailed by a system schematic and specications.

The assembly and installation instructions described in this manual have been carefully prepared. It is very

important to read these instructions thoroughly before proceeding with the collector installation. An effort has

been made to conform procedures in this manual to the specications of various governmental and agency solar

programs. Also, many programs allow substitution of manufacturers’ standards for program standards. If this is the case, the enclosed manual can be used to comply with program standards. Cases where it is unclear whether the enclosed manufacturers’ standards can be substituted for program standards should be brought to

the attention of the particular program administrator or to Oventrop Corporation for clarication.

Be certain to follow all applicable building and safety codes for installations of solar thermal collectors. Compliance with local codes is essential. Local code requirements must be met for penetrating structural

members and re-rated assemblies. Collectors and piping must be installed in such a way that the performance of any structural member or re-rated assembly is not reduced. Be especially aware of safety regulations when

working upon rooftops. It is the buyer’s responsibility to secure all permits and approvals before purchasing and attempting the installation of this equipment.

Specications are subject to change without notice.

Guidelines and Precautions

Installing Collector Arrays

It is not recommended to install more than three 16-tube collectors in a series (64 tubes). Larger

installations will require parallel piping for balanced ow through each array. Balancing valves should

be installed on multiple arrays. One roof mounting kit is needed for each single collector module. Each additional collector will require an expansion kit.

Closed Loop and Drainback

OVSOL collectors can be installed for both closed loop and drainback solar heating applications.

Freeze Tolerance Limits

Freeze tolerance limits are based upon the freeze and burst protection of the antifreeze used in the solar closed loop, or the mixture of the glycol-to-water ratio. Oventrop NT-40 is a 40% glycol-to-water mix with freeze protection to -6o F and burst protection to -60o F. Oventrop NT-50 is a 50% glycol-to-water mix with freeze protection to -30o F and burst protection to -60o F. For additional protection, the Regusol 130 EL control has an antifreeze function (“OCF”) that can be programmed to enable the circulator to protect the antifreeze from freezing or thickening.

Shedding Snow

In regions of snow accumulation, evacuated tube collector tilt angles above 50° will shed snow from collectors even after severe storms. Therefore, in heavy snow areas, it is critical that collectors be sloped to

at least a 50° tilt angle. If collectors are installed on a at roof in an area that receives heavy snowfall, the

lower end of the units should be at least 18” above the roof level to minimize chances of snow build-up on the bottom of the collectors.

Transport of Collector

The collector should be transported to the roof in parts and then assembled together on the rooftop.

Lightning Protection

In areas of high incidence of lightning, one lightning rod should be considered. If there is a ready-made lightning protection device, please connect it with the collector.

Minimum Inclination Angle of Collector (for Evacuated tube collectors only)

In order to ensure heat pipe delivery, a minimum inclination angle of 25° is necessary for OV SOL-5 collectors. If the tilt angle of the roof is not above 25°, please build necessary roof mounting racks.

Precautions

Temperatures in excess of 390 °F are possible in the condenser (top metal protruding bulb) when exposed to bright sunlight or diffused insolation. DO NOT TOUCH the condenser. Store the tubes in a safe location, away from the sun, during the installation of the roof mounting rack. Tubes are installed as the last step. Oventrop Corporation will not be liable for burns or personal injury due to the touching of a hot condenser. Handle the tubes with care to avoid accidental bending of the heat pipe at the condenser which may cause damage to the heat pipe or the vacuum seal.

The maximum solar loop operating pressure is 87 psi. The pressure relief valve must be set to open below 87 psi. A 75 psi pressure relief valve is suggested. Normal operating pressures for a solar closed loop are 25 to 35 psi.

Solar thermal system design guidelines

Solar hot water systems are simple in principal but complicated in practice. This guide is designed to describe and explain the process for designing a solar hot water system. There are many ways to design a solar hot water system to achieve the same end result. The two system types that Oventrop uses are external heat exchanger systems (i.e. the Regusol X) and Immersed coil heat exchangers (i.e. internal coil tanks). All of Oventrop’s systems are based on one of these two variants.

Solar Design Basics Incoming solar radiation at the earth’s surface on a perfectly clear day is approximately 300 BTU/H

per square foot. With that said, solar collector performance depends on several factors. These factors include, but are not limited to: ambient temperature at the location of the solar collector,

required operating temperature of the working uid in the collector, incoming solar radiation

(energy), geographical location of the collector, shading of the collector, and inclination angle of the collector.

The difference in temperature between the working uid and the ambient temperature drives the heat loss of the solar collector. This temperature difference has the greatest inuence on the solar collector’s thermal efciency. This efciency measures the solar collector’s ability to convert incoming solar radiation to usable heat in the form of a hot working uid. This hot working uid can

be used for any application. The availability of solar radiation (energy) is dependent on weather, time of year, site shading, and collector inclination angle. Throughout the year, the distance of the sun from the horizon will

change from the longest on the rst day of summer to the shortest on the rst day of winter. This

translates to a 47-degree change in the sun’s angle with respect to the collector throughout the year. The optimal inclination angle to minimize this change and maximize year-round performance is equivalent to the latitude at which the collector is located. Shading at the collector site determines the amount of available solar radiation to which the collector is exposed. Understanding that all of the above factors affect the performance of the solar thermal collector, one cannot make a location independent generalization of collector performance. Design conditions are calculated as the maximum instantaneous solar radiation, in other words, the most energy the system can handle at any given time. For design conditions we assume the collector

is at an operating efciency of 75%, on a clear day, facing south, with no shading. Due to this efciency the maximum output of the solar collector at design is rated at 225 BTU/H per square foot. This value is in no

way a guarantee or estimate of any Oventrop collector’s performance. The table below shows the design

BTU/H

rating of each Oventrop solar collector.

Collector Type Design Conditions BTU/H rating

OV 5-16 Evacuated tube collector 6,277 BTU/H OVF-21 Flat plate collector 4,230 BTU/H OVF-32 Flat plate collector 6,615 BTU/H OVF-40 Flat plate collector 8,280 BTU/H

Table 2, below, shows the design ow rates for each Oventrop collector type.

Collector Type Design Flow Rate per collector

OV 5-16 Evacuated tube collector 0.75 GPM

OVF-21 Flat plate collector 0.525 GPM OVF-32 Flat plate collector 0.80 GPM OVF-40 Flat plate collector 1.0 GPM

082809

Page 7

These ow rates were chosen based on the collection area of each solar collector and the incoming solar radiation at design conditions. The ow rates allow the collectors to achieve an 18 degree Fahrenheit temperature

rise across the solar loop.

‘The sun is the source, the system is the battery.’

Solar energy is only available for a limited time during each day. It is because of this that the energy must be captured and stored for later use. The amount of energy stored is related to the system operating temperature

(i.e. radiant oor heat at 100F or fan coil units at 180F), the storage volume, and to the maximum temperature in the storage vessel. Maximum energy storage [BTU’s] is calculated using equation 1, below.

Maximum Stored Energy = 8.33 x Storage volume [Gal] x (Max. tank temp. – System operating temp.)

Where, Storage volume is in gallons and all temperatures are in Fahrenheit. Optimization of this equation has determined the design number of gallons per collector. The table below shows the number of gallons of storage recommended per collector.

Collector Type Gallons of Storage per Collector

OV 5-16 Evacuated tube collector 66 Gallons OVF-21 Flat plate collector 27 Gallons OVF-32 Flat plate collector 41 Gallons OVF-40 Flat plate collector 53 Gallons

These storage values are calculated for a national average. Since daily solar radiation varies signicantly from the

South to the North, these storage values are not required, only recommended. Less storage can be used in the northern latitudes and more storage can be used in the southern latitudes. The storage values should only vary plus or minus 5% from the recommended values listed above. Another way to think of solar storage is as the fuel tank of the system. It is used to store energy that can be used over the entire day. In this way the daily load is matched to the daily collector output. Oventrop solar hot water systems are designed to optimize the transfer of energy from the collectors to the solar storage vessel.

Small systems

Internal coil tanks are used for Oventrop smaller systems. This allows for the ease of installation for system packages. Oventrop has pre-packaged solar domestic hot water systems for daily loads of 80 and 115 gallons. Depending on location these packaged systems will provide between 30 and 70 percent of the annual domestic hot water load.

Using a similar conguration as the pre-packaged systems, larger domestic hot water loads can be accommodated.

Variations of small systems are sized by tank size and can be arranged for up to 160 gallons and 230 gallons of daily usage. These small systems are comfortably in the design range of the Regusol EL 130 solar pumping station. This

pumping station is designed for a maximum ow rate of four (4) gallons per minute. Because the Regusol EL 130 is constructed in ¾”, the maximum ow rate is based on the maximum trouble free ow through ¾” pipe.

Medium systems

Medium systems are above the ow range established for the Regusol EL 130 and have increasingly larger storage

requirements. It is for these reasons that the Regusol-X pumping station with heat exchanger was developed.

External heat exchangers provide exibility of design and reduce cost when considering larger storage volume and

collector arrays. The Regusol-X is designed to be used with any storage vessel that is built for hot water storage; it does not require internal heat exchangers.

082809

The design limits for the Regusol-X are based on the pressure drop through the heat exchanger, the pump capacity, and the maximum output of the heat exchanger. The table below lists the maximum number of collectors allowed to be used with each Regusol-X.

Collector Layout, Orientation, and Siting

Place the collector where it will receive the maximum amount of sunlight available in your location. OVSOL collectors may be installed on a roof, against a south facing wall, or on the ground.

Orientation

Orientation and tilt are critical to performance. The OVSOL collectors should be oriented (faced) as close to true south as practical, although they may be faced as much as 20° east or west of true south with less

than 5% loss in capacity. Because the earth’s magnetic eld is not aligned parallel to the earth’s north-

south axis, there are some parts of the United States where the needle of a magnetic compass can point as much as 20° east or west of true north. There are several ways to determine true south in your area. You

can consult a local surveyor, a plot map in your

local tax ofce, or a recent isogonic chart of the

United States published by the U.S. Coast and Geodetic Survey. Adjust your magnetic compass reading according to the meridian nearest to you. Do not use old charts, as there are annual variations in the readings. When using a magnetic compass, beware of standing near large metallic objects or power lines because they will affect the compass readings.

Shading

Trees, chimneys, dormers, other buildings,

new construction, and even fences may shade the collector array, especially in the winter when sun angles

are low and shadows are long. Be sure the collectors are placed where they will be not shaded by these

obstructions. As a rule, no more than 5% of the collector area should be shaded between the hours of 9:00 a.m. and 3:00 p.m. It is highly advised to make use of a solar site selector while determining suitability for a collector site.

Angle of Inclination or Tilt Angle

For domestic water, use an optimum tilt of the site’s latitude plus 5°, although the slope may be 10° greater or less with a capacity loss of under 5% for the system. For a solar space heating system, a steeper tilt angle is important for optimal winter performance. The steeper tilt will favor winter system operations when the sun is low in the sky. Therefore, for space heating systems chose a tilt of latitude plus 15°. The variation of 10° either way will not seriously affect the total annual performance of the system, all other things being equal.

The following chart will help you determine the tilt angle of roof pitches. For space heating systems, always

082809

Page 11

have collectors sloped at optimal tilt for winter performance. Install a collector rack for tilt angle support whenever necessary.

Roof Pitch Tilt Angle

4/12 18° 6/12 26° 10/12 39°

Integrating with Building Architecture

Maintaining a pleasing appearance to the building’s architecture is important for adding solar collectors to a roof or on the ground. Most homes are not oriented well for solar gain, so getting the collectors at just the right orientation and tilt may not integrate well with the roof lines.

Roof Pitch Tilt Angle

12/12 45° 14/12 49°

22/12 61°

With domestic hot water systems, there may be greater variations to tilt and orientation without large annual

losses, and in some cases may justify  ush-mounting collectors. Space heating systems must have a

steep slope and be oriented within 30° of true south. For these larger space heating systems, the layout

should integrate into the roo ine. For new construction, integrating OVSOL collectors into the building’s

roof system should be addressed by the solar designer to the architect.

Shedding Snow

A tilt angle of 50° or more is necessary in regions of heavy snowfall and accumulation. Tilt angles of 50° and above will shed snow from OVSOL evacuated tube collectors even after severe storms. It is critical in

heavy snow areas that the collectors be sloped to at least a 50° tilt angle. If collectors are installed on a  at

roof in an area which receives heavy snowfalls, the lower end of the units should be at least 18” above the roof level to minimize chances of snow build-up on the bottom end of the collectors.

Shading

To avoid shading by collectors on each other, the front to front dimension must be 2.5 times the highest point of the front collector.

Shingle Roof Kit (540 00 28-FM)

Mounting of Collector Feet

Collector feet may be lag bolted into the roof rafters. Since most roof trusses or rafters are built on 16-inch centers, locate the comers so that the width dimension falls on the 16-inch center. To locate the nearest

rafters, use a stud nder. Once the rafter is located, drill a small diameter pilot hole to verify the rafter’s center line. Be sure to lift the upper shingle and predrill into the underlying (covered) row to prevent water

leaks. Lift shingles carefully to avoid tearing. Always seal pilot holes not being used.

8 tube: 16” - 25”

16 tube: 48” - 66”

Roof Hooks

Mark the pilot hole for the center line of the roof rafter or truss. Next, pre-drill two holes for each collector foot into the center line of the rafter using a drill bit smaller in diameter than the lag bolt supplied. Apply a generous amount of polyurethane sealant around and within the pre-drilled hole. Screw the collector feet in place. Avoid over-tightening and stripping the lag bolts. You may apply a small amount of sealant to the lag bolt heads to prevent water leakage. The important thing is to locate the collector feet atop roof joists so that the weight of the collector is supported. Select rafters so that two tubes will overhang to the right and left for an 8-tube module. For a 16-tube module, you may allow up to four tubes to overhang to the left and right of the rafters. The overhangs are necessary for better weight distribution.

Installing the collector feet and ashing

No need to remove any shingles to install the ashing. Base plate is rst screwed into a roof rafter or block and ashing is slided under the roof shingle covering the

installed base plate.

Tools Required:

- Cordless drill with #2 square drive bits

- Tape measure, stud nder, chalk line

1. Locate the rafters and snap horizontal and vertical lines to mark the installa-tion position for each upper mounting foot. Blocks, installed in the attic, may have to be positioned between the rafters to make sure the base plate has a structural member to screw into.

Sealant must be applied to

any penetration of the roof

2. Install the base plate with the square drive screws. Mark the screw locations and apply polyurethane sealant at

the penetrations. The baseplate must be securely at-

tached atop the roof and into the roofs structural member.

3. Install ashing by sliding it into place under then next row of shingles. cover base plate with the ashing pocket .

4. Install the collector foot onto the ashing using

neoprene-bonded washer and stainless locking nut.

Flush Mounting on Tile Roofs Tile Roof Kit (540 00 28-TK)

Mounting of Collector Feet

On a tiled roof, it is generally easy to locate the rafters by simply lifting out individual tiles at the desired foot placement. You will see the where the sheeting has been nailed into the roof rafters below. This is your visual

indicator for the rafters. Predrill small pilot holes to nd

the center line of the rafters.

Install four collector feet by lag bolting feet into roof rafter.

If necessary, use perforated plates to extend the tile roof hooks from the roof rafters, or lag bolt into spanners or blocks between the rafters, to get the width needed between collector feet.

Place the feet vertically so that the rst angle on the roof

hook clears the top edge of the tile resting below.

Apply a generous amount of polyurethane sealant in and around the lag bolt holes before tightening bolts into place. Seal any other test holes made for pre-siting rafters.

The collector feet must be aligned vertically and horizontally.

Perforated plate

Reinstall tiles around the collector feet.

Mounting of Collector Feet

For each collector support rail, attach the rectangular

blocks in the hole fourth from the top and rst from the

bottom as shown by the image below.

On the top end in holes 1 and 3, using the square nuts, attach the manifold bracket.

Secure the rails to the seams of the roof as seen in the illustrations. Select seams so that two tubes will overhang to the right and left for an 8-tube module. For a 16-tube module, you may allow up to four tubes to overhang to the left and right of the seams. The overhangs are necessary for better weight distribution.

Once the rails are secured to the roof seams, the tube support rail should be bolted into the second holes from the bottom.

After installing the tube support rail, slide the manifold through the manifold brackets at the top of the collector.

Insert the two outer tubes and check for square lines.

Insert remaining tubes from one side to the other.

The bracket is to be fastened to the metal seam clamp through

the hole closest to the vertical.

Page 21

Assembling the Collector Frame

Place the collector rail on the collector top and bottom feet and install rail where it can be lined up with the collector feet bolt holes. If possible, choose the fourth hole from the top of the verticle frame to set the bolt into the top collector foot. Tighten bolts.

Attach the manifold support into the rst and third holes of the vertical collector frame. Bolt the manifold support

into the collector frame with square nuts.

Bolt the bottom tube support with square nuts on the

second hole from the bottom of the vertical collector frame; tighten bolts to avoid the bottom support from slipping. Line up the collector clips at the bottom tube

support rail to the manifold dry well ttings for the

evacuated tubes to line up square. There may need to be a verticle adjustment, so don’t tighten the bolt

completely until a tube has been pre-t.

Install one vacuum tube on either end. Using corner-tocorner measurements, ensure the collector assembly is squared.

Install each vacuum tube from one end to the other.

Connect Piping to the Manifold

With each roof mounting kit, there are adapters to pipe to the manifold. Included are:

l Two compression tees to attach to the supply and return

terminations on each collector manifold or collector array;

l Two copper pipe adapters that adapt from 22mm copper

pipe size (at compression tee) to 3/4” copper pipe. Also

included in some roof kits are two stainless steel exible

hoses and additional compression couplings for copper pipe adapters.

NOTE: Use 1/2” copper supply and return for collectors with up to 24 tubes (one 8- and one 16-tube collector) and 3/4” copper for collectors with a 4- to 16-tube collector array. Preferably use Type L. Do not use PEX plastic tubing.

PEX tubing cannot withstand temperatures above 200°F and will fail. Always insulate outdoor tubing with high

temperature Insultube and weather proong against UV

degradation. Use insulation with a wall thickness of at least 3/4”.

Thermowell must

be soldered in

place.

Install compression tees at supply and return on collector manifold. Make sure the compression ring is well onto the copper pipe terminating the manifold so that the compression ring will not slide off the pipe as the compression nut is tightened.

Install the Thermowell, which is for the collector sensor, on the return outlet tee. Solder the threaded Thermowell into the tee before installing the compression tee to the header. Smear some heat transmission paste on the sensor and insert the sensor into the Thermowell. Lock sensor into place with set screw on the Thermowell.

Install the manual air vent on the manifold’s supply inlet tee. If the piping rises above the collector on a closed loop system, add an additional manual air vent at the highest point of the loop.

Use an angle nder tool to set the desired collector tilt angle during installation.

Table 1 below is to help you nd distances between the front and rear feet (B), and

the cut length for the rack leg (A) at various collector tilt angles.

The table is for collector tilt angle from a horizontal plane, such as for a at roof or for ground mounting. (gure 1)

When mounting on a pitched roof (gure 2) the table can be used by subtracting the roof pitch (angle) from the collector tilt angle to nd the remaining angle for Table 1. With this method the collector legs will be perpendicular with the roof pitch (gure 2).

Mounting Hardware and Installation

The adjustable rack installation hardware is specially designed to speed collector installation. This hardware consists of four Quick-Lock collector clamps for the rear top hinge, two Quick-Lock collector clamps with locking screws for the front bottom hinge, four triangle brackets (collector feet), two aluminum square tube strut for collector legs, bolts, nuts and washers. (See page 33).

After locating the mounting points for the collector feet, the base plate and

 ashing should be installed (See page 38).

Install the triangle brackets on top of the  ashing using the neoprene-

bonded washer and stainless locking nut.

The rear struts should be cut and drilled to the desired length from Table 1.

Attach two Quick-Lock collector clamps with locking screws to bottom of the collector. Keep the locking screws loose. Secure the bottom Quick-Lock clamps on the collector and drop the clamp into the triangle bracket using the bolt, washer, and nut provided. Tighten locking screws after collector is set on the triangle brackets. See diagram 1.

Attach the four Quick-Lock collector clamps to the top of the collector. Using two Quick-Lock clamps per collector leg, bolt the collector leg (mounting strut) to the top of the collector. Attach both collector legs.

Raise the collector and bolt the bottom of the collector legs to the collector foot with the bolt, washer, and nut provided. See diagram 2.

Square up the collector legs and tighten all the nuts and bolts at the collector feet and the rear collector hinge.

Flat Plate Collector Piping

The piping of the system should be considered before a nal decision is made

on how the collectors are mounted. Piping should be made of copper tube of

the type meeting local codes, insulated with Armaex or similar, and painted

or wrapped with aluminum tape where exposed to ultraviolet radiation. Care should be taken in the spacing of collectors as attachment of piping is easiest with properly aligned collectors. The collectors and piping to the storage tank should be slightly sloped downward (3” in 8 feet) to allow draining in case of freezing conditions. A manual air vent should be installed at the top of the collector on the outlet. Soldered connections should be made with 95/5 solder.

The outlets of the collector are 1” copper pipe nipples. The copper union makes attachment of piping to collector

easy. Teon tape or high temperature, high quality pipe

sealant should be used when making threaded connections. The collector inlets should be piped similarly but without the air vent.

Sensor Mounting at Collector

The controller heat sensor is mounted to the nipple outlet of the collector (Figure 14). A stainless steel screw clamp should be used. The entire nipple should be wrapped thoroughly with insulating tape so that the sensor is isolated from the outside air.

COLLECTOR FOOT MUST BE ATTACHED TO THE BASE PLATE

USING THE CENTER HOLE.

No need to remove any shingles to install the ashing. Base plate is rst screwed into roof rafter or block and ashing is slided under the roof shingle covering the

installed base plate.

Tools Required:

- Cordless drill with #2 square drive bits

- Tape measure, stud nder, chalk line

1. Locate the front feet locations on rafters and snap horizontal and vertical lines

to mark the installation position for each lower mounting foot. Blocks, installed in

the attic, may have to be positioned between the rafters to make sure the base plate has a structural member to screw into.

3. Install ashing by sliding it into place under then next row of shingles. Cover the base plate with the ashing pocket .

4. Install the collector foot as shown below using neoprene-bonded washer and stainless locking nut. The collector foot must be tightened fully to restrict unwanted movement.

Piping the Solar Tank with Integrated Back-up as a One Tank System

Use 3/4” copper pipe for plumbing the tanks. To prevent heat loss through the copper tubing, insulate all tubing with at least 1/2” wall tube insulation. This should include the cold water feed to the solar storage tank up to 6 feet from the tank. A check valve should be installed on the cold water feed line to the mixing valve to prevent hot water migration into the cold water piping.

The solar tank should include valves and piping for service. A domestic hot water expansion tank can be installed on the cold water feed to the tanks. The expansion tank

should be installed downstream from a back ow preventer, for cold water feed to the tanks.

Service Valves and Instructions for Emergency

To isolate or service the hot water system in an emergency, turn system isolation valve #1 off.

To leave the system in an unoccupied house when hot water will not be drawn, the solar system should be drained of antifreeze and the controller turned to “off” or unplugged. You may also turn the system isolation

valve #1 off if no hot water ow to the xtures is desired.

Piping the Solar Tank and the Auxiliary Hot Water Service for Two Tank System

The solar tank should include valves and piping for service. In addition, the back-up water heater can have valves installed for solar hot water bypass.

A domestic hot water expansion tank can be installed on the cold water feed to the tanks. The expansion tank

should be installed downstream from a back ow preventer, for cold water feed to the tanks.

Service Valves and Instructions for Emergency

To isolate or service the hot water system in an emergency, turn system isolation valve #1 off.

To isolate the solar tank from the auxiliary water heater, the normally open solar bypass valves #2 and #4 are shut off, isolating the solar tank from the supply of water. The normally closed valve #3 is then opened for bypass. Under no circumstances are valves number 1, 2 & 3 to be left open during solar operation.

valve #1 off if no hot water ow to the xtures is desired.

Piping and Insulating the Solar Loop

When piping collectors, use 3/4” copper for one to four 16-tube collector arrays. Preferably use type L.

Never use PEX plastic tubing. PEX tubing cannot withstand temperatures above 200°F, and fail in solar loops.

Always insulate solar loops with at least a high temperature elastomeric insulation. This exible rubber foam

insulation may be protected against UV degradation with a mastic or a 15-year latex paint applied to the

surface. High temperature berglass, urethane, and isocyanurates are also used on solar loops and have

jackets that enclose and protect the insulation. Use insulation with at least a 3/4” wall thickness for all outdoor

piping. Always insulate completely around pipe ttings and at the collector ttings. Pay particular attention

to insulation detail at the collector sensor. Copper pipework must be supported by pipe hangers, split ring hangers or Unistrut clamps. Check your local codes for pipe sizes and support distances for vertical and horizontal runs. The supports must not hold onto and compress the insulation. Pipe support hangers should be secured directly to the pipe.

Collector Flush, Leak Check, and Fill Procedure

Before proceeding with the instructions outlined in this section, the solar storage tank should be

lled with water. The collector loop then should be leak checked, ushed, and lled. A Regusol “ll and ush” valve should be installed for system charge-up. Filling or “charging up” a solar

closed loop incorporates a 1/2 HP utility pump available through most Oventrop dealers.

Leak Check and Flush

1. To ensure there are no leaks, air test the system to approximately 60 PSI. Check and repair

any leaks. When the solar loop is leak-free, release air and ush system with tap water.

2. Before lling the collector loop with antifreeze solution, it must be ushed free of any ux, copper lings, or debris. Straight tap water may be used for this purpose.

3. To perform this step, hook up a hose from tap faucet to the ll port and run another hose from the drain port to a drain or outdoors. Close center ball valve on “ush and ll.” Open water tap to begin ushing. Flush the system with tap water for approximately 10 minutes to assure there is no solder, ux, or debris left within the collector loop piping. This step may also be used to cool the collectors before lling the system with propylene glycol.

Fill Procedure

Charging the collector loop will require approximately 3

- 8 gallons of Oventrop NT40 antifreeze (provided). It is a premixed waterpropylene glycol solution of 40% propylene glycol to 60% water and will provide freeze protection to -6 oF.

No mixing is necessary.

Oventrop

Solar Collector

Array

If collector loop is to be charged during the sunlight hours, collectors should be covered for at least one hour before beginning; or the collector may be cooled with water using procedure in step 3 (above).

Connect pressure side of charge pump with washing

machine hoses to the ll

port. From suction side of charge pump, attach another hose to the bucket of the propylene glycol solution. Attach another hose from the drain port to an empty bucket. If the system was

just ushed with water, drain down the water pressure to prime the charge pump. Drain water

pressure into empty buckets.

Set up for lling with solar heat transfer uid. Turn center ball valve of “Regusol ll and ush” perpendicular to have propylene glycol ow throughout solar closed loop.

082809

Page 73

Turn on ll rig and pump propylene glycol. If pumping out water, have an empty bucket on the

drain port hose to collect water until the color of antifreeze returns. Then put drain port hose into antifreeze bucket for circulating antifreeze. Run the charge pump until no air bubbles are seen returning to the bucket. Periodically close drain port to allow pressure to build, then reopen to purge any air that may be trapped. Watch for air escape. Repeat this procedure until

air is no longer returning to the ll rig pail.

To complete system ll and charge, close the drain port and ll system to pressure of 30 to 35 psi. Close ll port and turn off charge pump. Turn center ball valve of “Regusol ll and ush” parallel to direction of ow to have propylene glycol ow throughout solar closed loop installation with the system pump in operation. Cover ll and drain ports with hose caps.

Open air vent atop solar collector to eliminate any air trapped at the high point of the system. Next open the air vent to remove air from the deaerator at the Regusol 130 EL.

Commissioning the System

Before activating system the following checks should be made:

System lled with water (tank).

Appropriate cold and hot water bypass valves are set for series water ow through tank(s).

Collector and tank sensors connected.

Regusol is wired and solar loop is air-tested for leaks.

The collector loop can now be lled with the recommended anti-freeze. Once the solar loop is lled, place Regusol thermometer handles in the fully open position and the ll and ush valve in fully open position.

Plug in the Regusol controller for operation.

Controller will start and be in automatic mode of operation. Digital display and indicator light should illuminate. If the collector temperature is above the tank temperature by 12º F, the circulator should start and run. Flow meter will indicate circulation. If there is noise of air circulating through the pump, the system must be recharged to remove air bubbles. Solar closed loops must be free of air bubbles.

If the collector temperature is below the tank temperature, circulator should not run. If circulator is not running, set the controller to the “On” position (see Operation and Control-

ling the Regusol Controller) to check circulator operation and indication of ow. Remember to

leave the solar controller set in the “Auto” mode of operation when completed.

If circulator fails to operate, refer to Troubleshooting checks on the following pages.

It is unlikely that system malfunctions will develop within the Regusol. Should they occur, however, the following procedures will prove helpful. Several of the procedures indicated require the use of test equipment, such as a volt-ohmeter with 10K scale. If this equipment is not available to you, contact your authorized Oventrop dealer or distributor for service.

Sensor Test

Use an Ohm meter to measure the resistance of the sensor circuit. If an open circuit or a short circuit situation is detected, then inspect the sensor wiring before suspecting the sensor. Measure the sensor resistance without the interconnecting wire before removing the sensor. The resistance should match the chart for a given temperature.

Maintenance Procedures

Cleaning. The solar collectors will not require cleaning in a climate in which there is periodic rainfall. A light coating of dust will not seriously affect performance. In dry, dusty climates, collectors should be cleaned occasionally.

Circulators and Controller. No scheduled maintenance is required for the uid lubricated circulators or controller system. In the event of a circulator or controller malfunction, refer to troubleshooting Checks.

Collector Loop Fluid. Collector loop uid must be changed in order to maintain adequate freeze and corrosion protection. Antifeeze checks should be performed annually. Collector loop uid should be replaced

every 5 - 7 years. To prevent elevated temperatures from developing at the collectors, do not turn the system off while absent from premises for extended periods.

Solar Storage Tank. Periodically drain a small amount of water from the bottom of tank to prevent sludge or sediment buildup in the solar storage tank.

Scaling. If your water supply contains a large percentage of minerals (hard water), we strongly recommend that a water softening device be installed to protect not only the stainless steel solar storage tank and coils but also the existing hot water heater and its plumbing as well.
