General Terms and Conditions

Installation and commissioning should be undertaken by an MCS Certified

Solar Installer Company.

General terms and conditions of warranty state that all installations must completed by a MCS certified and qualified solar installer company who is currently on the live MCS register of installers.

All installer companies should work to the Building

Regulations in force at the time of installation..

The manufacturer’s warranty will only apply if these installation instructions are followed. The warranty does not cover any damage caused by non- observance of this manual.

The correct functionality of the system is only guaranteed if the installation instructions are followed.

The end client should be informed at system handover that system should be checked visually once pre year and the heat exchange fluid changed once every four years.

This document is part of the warranty and should be kept in a safe place and handed over to the end user client on completion of works.

Instructions for installation and transport

Mint Solar Collectors kits are delivered on pallets.

Never store outside in water logged conditions.

Always store on a flat surface with glass facing upwards maximum 8 collectors per stack., or vertical with glass facing outwards.

The use of a carrying strap is recommended for transporting the collector. The collector must not be lifted at the connections.

Avoid impacts and mechanical actions on the solar collector.

Mint Solar Collectors should only be used in professionally designed systems with all system components and materials being appropriately rated for use in solar water heating systems and properly installed .

Structure

The collectors may only be mounted on sufficiently loadbearing roof surfaces and substructures. The structural load- bearing capacity of the roof and the substructure must be assessed on- site, by a suitably experienced professional before mounting the collectors.

Particular attention should be paid to the quality of the timber substructure in terms of the stability of the screw joints necessary for installing the collectors.

In particular, it is essential to have the entire collector structure verified at the installation site by a qualified engineer in regions with high wind speeds.

The assessment should also take into account any special features of the particular site that could lead to increased loads (high wind speeds, snow loads etc).

Lightning protection / Potential bonding of the building

It is not necessary to connect collector arrays to the lightning protection of the building (please observe the specific electrical regulations). For installations on metal substructures at the installation site, authorised lightning protection specialists must be consulted.

The metal tubes of the solar circuit must be connected to the main potential equalization bus by means of a conductor

(green/yellow) with a cross- section of at least

16mm² CU (H07V- U or R). It is possible to ground the collectors to a ground rod. The grounding line must be laid outside the house. The ground rod must also be connected to the main potential equalization bus by a line with the same crosssection as above.

Connections (compression connection fittings)

Connect the collectors using the certified solar compression connections supplied with your kit.

Precautions must be taken to protect the connection pipes against temperature fluctuations caused by heat expansion

(expansion bends/flexible piping). In this case, no more than

6 collectors may be connected in series.

Larger collector arrays must be assembled with expansion bends or flexible members inserted in the links

(IMPORTANT: check the pump design). When tightening the connections, always apply counter pressure with a wrench or another spanner to prevent damage to the manifold connections.

Collector inclination / General notes

The collector is suitable for installation at an angle of between 15° - 75° Steps must be taken to ensure that water and other contaminants such as dust, etc. are prevented from getting into the collector connections and ventilation holes.

Warranty

Warranty claims can only be made if an appropriate specification of antifreeze is used and maintenance is carried out correctly.

Ladder and scaffolding assembly

Safety Precautions

Before commencing mounting work on roofs, it must be ensured in all cases that the non personal fall protection and fall- arrest systems required by DIN 18338 (Roof Covering and

Roof Sealing Works) and DIN 18451

(Scaffolding Works) are in place. See also

Builders’ Protection Ordinance

If non- personal fall protection or fall- arrest systems cannot be installed for technical reasons, all personnel must be secured by means of suitable safety harnesses!

Only use safety harnesses (safety belts, lanyards and straps, shock absorbers, fall arresters) that were tested and certified by authorized testing bodies.

If non- personal fall protection or fall- arrest systems are not provided, working without the use of suitable safety harnesses may lead to falls from heights and therefore cause serious or lethal injuries!

Ladders not properly secured against sinking in, sliding or falling over may lead to danger- ous falls!

Whenever you are near live overhead electric cables where contact is possible, only work if:

- it is ensured that they are voltage- free and this is secured for the duration of work.

The live parts are secured by the ESB by covering them or cordoning them off. And are deemed safe by ESB transmission supervisor. Or advised safety distances are maintained.

Voltage radius:

1m with .......................voltages up to 1000V 3m with ........voltages from 1000V to 11000V 4m with

......voltages from 11000V to 22000V 5m with

......voltages from 22000V to 38000V

> 5m in case of unknown voltages

The manufacturer hereby guarantees to take back products identified with an eco- label and to recycle the materials used.

Only the heat transfer medium specified may be used!

Safety harnesses should be fixed above the users whenever possible. Safety harnesses should only be fastened to sufficiently load bearing structures or fixing points!

Never use damaged ladders (e.g., wooden ladders with split runners or rungs, or bent or buckled metal ladders). Never try to repair broken runners, rungs or steps on wooden Ladders!

Ensure that ladders are put up safely. Ob- serve the correct leaning angle (68° - 75°).

Prevent ladders from sliding, falling over or sinking into the ground (e.g. using wider feet, feet suited to the ground or hooking devices).

Only lean ladders against secure points. Secure ladders in traffic areas by suitable Cordoning.

Contact with live electric overhead cables can be lethal.

Wear protective goggles when drilling and handling solar collectors evacuated tube collectors have a danger if damaged of implosion !

Wear safety shoes when carrying out installa- tion

Work!

Wear cut- proof safety gloves when mounting collectors and handling evacuated tube collectors

(danger of implosion)!

Wear a helmet

Prior to installation

Check the proposed collector siting is suitable. The collector is suitable for flat roof, tiled roof, cement and concrete roof structures. The installation should be carried out by able and qualified persons only. Its is the responsibility of the end user to adhere to local planning and conservation regulations.

The collectors must be fixed only to a load bearing roof structure and substructures. A structural survey may be required to calculate the permitted load. Do not mount the collector if you are unsure the structure will carry the load.

The location of the collector should be positioned at least 1 meter from any edge or ridge. A pre assessment of the location should take into account any additional factors that could lead to additional loads, ie, wind, air jets and snow. The collector arrays must be mounted in a way as to avoid snow piles reaching the collectors.

Use the correct mountings. The collector can be sup- plied with the correct fixings for both slopping roof and flat roof types. Not using the recommended fixings as outlined in this manual will invalidate any warranty. Please note - metal straps are not a recommended method of fixing.

Lightening protection

Non metal structures

Lightening protection is not required for collector arrays mounted to non metal structures, although it is recommended that protection diodes for the temperature sensors are installed. Lightening protection diodes protect the control unit from over voltage in the event of a lightening strike.

Metal structures

For installations mounted and fixed to metal structures a lightening protection specialist must be consulted.

Connection of collectors in series

The collector manifold inlet and outlet is 3/4” male.

Soldering onto the collector manifold is not permitted and will invalidate any warranty claim.

Connections can be of either copper tube or flexible metal pipe. When using copper tube precautions must be taken to account for temperature fluctuations caused by heat expansion. Do not connect more than 6 collectors

(SZ10-20) or 4 collectors (SZ30) in series without the use of expansion connectors.

Transport and Handling

All Micoe SZ series collectors are packed in cartons, are easy to assemble and can be transported to the site before any assembly is required.

Extreme caution should be adhered to when transporting evacuated tubes. Tubes are made from very strong glass, but will break if handled incorrectly.

All cartons must be stored on a flat level surface.

Cartons must not be stacked more than 5 high.

Cartons must not be stored upright. Due to their weight and fragile nature two people are required to lift all cartons. Please dispose of all packaging sensibly. Cardboard can be recycled.

System

Free standing planning prior to deciding

Filling the system

It is advisable to fill and flush the system prior to installing the evacuated tubes. If this is not possible cover over the tubes to block out the sunlight.

The system should be filled with a glycol based antifreeze with anti corrosion inhibitors. Tap water must not be used. The system can be filled with a hand fill pump or a pressure fill pump and must be bled to eradicate any air bubbles from the solar circuit.

Do not operate the air vent if the system is hot. There is a high risk of scalding. Only bleed the system if the temperature of the heat transfer fluid is less than 55°c

Operating pressure

Operating pressure 1.5bar cold.

The maximum operating pressure is 6 bar.

The maximum test pressure must not exceed 10 bar.

Good tube

Silver base. Vacuum present.

Problem

Cause

Heat transfer media

The system must be filled with a glycol based antifreeze with added corrosion inhibitors. The fluid must be checked once in every two years in respect to its antifreeze and ph value. Antifreeze is to be checked with a tester. The target value to be -20°c. If the target level is not reached, replace the heat transfer fluid. Ph levels are to be checked with a pH indicator rod. The target value to be pH7.5. If the target level is not reached, replace the heat transfer fluid.

Temperature sensor

The collector has a built in sensor sleeve. If there are two or more collectors mounted in series the sensor is to be inserted into the collector sleeve nearest the return flow back to the hot water store. Optimal contact can be achieved between the manifold and sensor by way of smearing the sensor with heat paste prior to insertion.

An optional lightening protection device can be istalled to protect the sensor from over voltage.

Maintenance

The collector and arrays must be checked periodically. An annual close up inspection must be performed to check for damage, leaks, contamination and tube failures.

Remedy

Wind load on roofs can create suction forces on the solar collectors. In order to minimize suction forces, the mounting frame must be installed as follows.

The subsurface must be sufficiently sustainable and appropriate for the weights to be installed. Upon it is therefore important to verify in advance that the roof structure is suitable to withstand the distributed load.

If the mounting frame will not be connected with the subsurface (structure, roof sub-construction), a loading of at least 200 kg per collector is required

(see fig 1). Additionally, the mounting frame can be connected with wire ropes at fixed hold points.

Support elements and fasteners must be provided by the installer. Moreover, in order to avoid wind noise to a large extent, the mounting frame must be installed at least 1 m from the roof edge. In areas with high wind speed or high construction heights, the loading must be calculated by a structural engineer.

Please refer to lightning protection and bonding to the structure.

Low working performance from heat pipe solar collector a) less solar isolation in you b) solar collector is shaded from sunlight.

Calculate correct collector size & adjust accordingly, or install additional heat source. i.e.

Gas boiler.

Where possible re- move source of shade or relocate collector.

Installation of the mounting frame on large open surfaces of galvanised or trapezoidal sheet roofs.

This types of installation should be specified only by a qualified structural engineer in accordance with current building regulations for such roofs.

c) Failed vacuum tube

Replace failed vac- uum tube with new.

d) Poorly installed heat pipe

Refit the heat pipe. Apply heat paste to condenser surface.

The frame can be bolted through these roof structures using oversized washers and rubber grommets to seal the roof however the sheets must be loaded with pebbles or substrate to equivalent weight.

e) Incorrect instal- lation angle

Reposition collector to an angle 51°

+/- 10% (UK only) f) High heat loss due to poorly insulated pipe lines.

Fig 1 Loading per collector

The collector field can be mounted at different angles according to individual applications.

For example larger systems used for heating support require a 60 degree angle in winter time

, to maximise solar gain, this reduces the system efficiency in sum- mer when the system is not required for heating.

Systems that require all year coverage such as hot water require 45 degree angle to maximise summer winter gain.

Systems that are predominantly used in summer are most efficient at 30 degree angle.

Install the profile rails in the in the pre drilled holes in the hypotenuse of the bracket insert the clamp and hanger brackets on the lower and upper profile rails mount the collector on the hanger brackets and clamp down each collector one at a time connecting the compression fittings to each collector as you install the next collector.

General

Installing the temperature sensor

The solar collector temperature sensor should be installed in the sensor sleeve nearest to the collector array flow. To ensure optimal contact between the temperature sensor and the surrounding environment, the gap between the sensor sleeve and the sensor element should be filled with a suitable conducting compound. All materials used for installing temperature sensors

(sensor element, conducting compound, cables, sealing and insulating materials ) must be suitably temperature resistant (up to

250 o c).

Operating pressure

The maximum operating pressure is 10 bar.

Removal of air from the system (bleeding)

The system should be properly bled at commissioning to remove as much air as possible from the system. We would recommend that after 2 to 4 weeks of operation the system is bled again .

Warning! -

When bleeding the system there is a risk of scalding due to steam and hot transfer fluid and appropriate care must be taken.

Only operate the bleeding valve if the temperature of the heat transfer fluid is below 60 o c. When bleeding the system the collectors must not be hot! Cover the collectors and, if possible, bleed the system in the morning.

Checking heat transfer fluid

The heat transfer fluid must be checked at least every four years with regard to its antifreeze content and pH value.

Check the antifreeze with an antifreeze tester and replace or refill if necessary. We would recommend a target protection of -25 o c.

Check the pH value with a pH indicator rod. If the limit pH value is less than 7.0 then replace the heat transfer fluid.

Collector maintenance

The solar collectors should be inspected visually, once a year, for any signs of damage, leaks or contamination.
