WPL Installation Manual for Rainwater Harvester Packages Garden System 1. HEALTH AND SAFETY 1.1. United Kingdom Health and Safety at Work Act 1974 Section 6a of this act requires manufacturers to advise their customers on the safety and the handling precautions to be observed when operating, maintaining and servicing their products. The user's attention is drawn to the following: All the sections of this manual must be read before working on the equipment. Suitably trained and qualified personnel must carry out installation. Normal safety precautions must be taken and appropriate procedures observed to avoid accidents. Refer to WPL Ltd for any further technical advice or product information. 2. PRE INSTALLATION CONSIDERATIONS This section of the manual is intended as a guide and as such does not cater for every situation that may be experienced during installation. WPL Ltd assumes that the installer/end user has ensured that all necessary permissions have been sought and granted and that the installation procedures will be carried out observing the requirements of the Health & Safety at Work Act and will involve good building and sound civil engineering practice. Please ensure that due consideration has been given to and appropriate action taken with regard to the following: • Planning permissions & Building Regulations and other regulating or interested parties. • Environmental regulator’s consent to discharge. • The legal responsibility for the plant as far as operation and maintenance and ongoing discharge is concerned. • Costs, legal implications and siting in consideration to shared systems. • The whereabouts of other services, pipes, cables, ducts, etc. • Local ground conditions. Is specialist knowledge of civil engineering required to cater for unusual soil conditions such as underground rivers, running sand, chemicals in the soil, etc? • The water table at the time of installation. Specialist knowledge is required when installing in an excavation that allows water to enter. • The water table in winter. Special consideration should be given to installations that will be subject to high water table pressure or flood conditions. The Rainwater Harvesting system will need to be installed so that it cannot “float” out of the ground. NOTE – In areas with high water tables the correct type of tank is required. If you are unsure please contact WPL Ltd prior to proceeding. • Siting. Advice from building control should be sought. NOTE – When using a suction pump the maximum distance from the tank should not exceed 8 METERS • Electrical supply. Only a qualified electrician should undertake electrical installation. A safe and reliable power supply is required at all times. DO NOT REMOVE ANY SUPPLIED PLUGS OR FITTINGS. • Before carrying out any work, electrical equipment must be securely isolated • Temporary barriers and warning signs should be erected around any excavations, open covers or manholes, in particular warning of deep water in the tanks. • Any visiting personnel must report to site office or householder on arrival and fully acquaint themselves with safety regulations applicable. 3. INTRODUCTION Rainwater Harvesting Systems: Garden Package: The home package consists of 3 main components:- 1. The tank: This is a polyethylene tank pre-sized based on the customers information and come complete unless pre-specified. The turret and lid should be assembled as per tank installation instruction. 2. The filter: the filter system is supplied as components and the enclosed instructions should be followed. 3. The pump and control module is made up of a submersible pump, delivery hose and garden spigot set. 4. DELIVERY 4.1 Off-loading Off-loading will only be at the nearest roadway to site that is suitable for heavy goods vehicles. If there are electrical cables overhead, ensure that there is adequate clearance or that the power is turned off. For off-loading from a lorry mounted with a crane, there needs to be a firm area for the stabilisers, the total width being a minimum of 4.6m (15 feet). If the nearest road access for a heavy goods vehicle is not adjacent to the site, it is the responsibility of the purchaser to arrange transport from the road to the site. If in doubt, contact WPL as soon as possible with any queries. Inspect the unit for any damage before placing on the ground. The unit should only be placed on level ground with no sharp stones, bricks, etc as they may damage the unit. All electrical equipment must be stored in dry, condensation free conditions until required. 4.2 Extent of supply a. See the delivery note for full details Ensure all components are free of damage before accepting delivery 4.3 Lifting and moving a. DO NOT attempt to lift the unit if it contains water. b. When moving across rough ground, great care should be taken to avoid increased loads due to sudden movement of the unit. 5 INSTALLATION 5.1 Introduction All installation procedures should be carried out observing the requirements of the Health and Safety at Work Act and involve good building practice. Tank and Pump Installation instructions Appendix 1. General arrangement Appendix 2. APPENDIX 1  General Notes 1.1 Safety The relevant accident prevention regulations must be observed during all work. Particularly when walking on the tanks, a 2nd person is required to secure the tank. The relevant regulations and standards must additionally be taken into consideration during installation, assembly, servicing, repair, etc. The system or individual parts of the system must be installed by qualified specialists. During all work on the system or parts of the system, the entire system must always be rendered inoperable and secured to prevent unauthorised reactivation. Except in the event of work carried out in the tank, the cover of the tank must always be kept sealed, as this otherwise constitutes a maximum risk of accident. Only original GRAF covers or covers approved in writing by GRAF must be used. GRAF offers an extensive range of accessories, all of which are designed to match each other and which can be extended to form complete systems. The use of other accessories may lead to impediments to the system's functional capability, therefore invalidating liability for resulting damage. 1.2 Identification obligation All service water pipes and outlets must be identified in writing with the words "Not drinking water" or in the form of images in order to avoid inadvertent connection with the drinking water mains even after a number of years. Mix-ups, e.g. by children, may still occur even in the case of correct identification. All service water extraction points must therefore be installed with valves with child-proof locks.          USE INSTRUCTIONS WARNING The motor-driven pump is supplied with this manual, ready for installation. Before installing and using the pump, carefully read the instructions provided here below. SIX TEAM srl declines all responsibility for accidents or damages originating from negligence, from the failure to follow the instructions of this manual or from uses other than those specified on the nameplate. The manufacturer declines also all responsibility for damages originating from an improper use of the motor-driven pump. IN@OUT motor-driven pumps are not designed to be used in swimming pools if bathers are present. The power cable of the motor-driven pump cannot be replaced. Motor-driven pumps with faulty power cables should be dismantled. Never use the power cable to support or move motor-driven pumps. Safety of people or property Carefully follow the sections highlighted with the following symbols.  ATTENTION: before installing the pump, carefully read this manual. Damages originating from the failure to follow the instructions provided are not covered by the warranty. PRELIMINARY INSPECTIONS Remove the IN@OUT motor-driven pump from the packing and check that are no faults. Immediately report all visible damage to the reseller/retailer.    Water head below 12 meters. The motor-driven pump must be connected to the power supply by means of an adequate line equipped with a differential current device with a maximum operating current of 30mA. No ventilation space is required for the motor, as this is water-cooled. ATTENTION: during installation, it is necessary to comply with all the safety provisions specified by competent authorities and by good practices. The motor-driven pump should never be installed in presence of children or young people under 18. PIPES Before connecting the pipes, verify that they are perfectly clean. In fixed installations, it is necessary to fix the pipes on their supports to prevent them from transmitting vibrations or stress to the pump. Verify that the pipes are fitted to the inlets of the pump with a torque that ensures sufficient sealing: excessively tightened pipes may damage the pump. Only use Teflon or fittings with "OR" rings for hydraulic connections. Inlet: verify that the diameter of the pipes never exceeds the dimensions of the pump mouths. When installing an IN@OUT motor-driven pump with an inlet pipe with a length above 10 meters, always use a pipe with an internal diameter greater than the pump mouth. Always check that the inlet pipe is perfectly sealed. In temporary installations with flexible pipes, always make sure that the inlet pipe has a reinforcement spiral in order to avoid restrictions due to the vacuum caused by the pump. Install a gate if the level of the sucked water is above that of the motor-driven pump. Water head below 12 meters. The motor-driven pump must be connected to the power supply by means of an adequate line equipped with a differential current device with a maximum operating current of 30mA. No ventilation space is required for the motor, as this is water-cooled. It is always advisable to use an inlet filter to prevent the entrance of foreign particles in the pump body.    SELF-PRIMING Recommendations to improve the self-priming of the IN@OUT motor-driven pump: 1) The inlet pipe should be equipped with perfectly sealed fittings and completely immersed in the fluid to be sucked; 2) The delivery pipe on the outlet of the pump should have a vertical section of at least 60 cm or with a flexible pipe, which must be placed vertically for temporary installations; 3) The pump body must be completely filled with fluid before it is started. The IN@OUT motor-driven pump has a check valve on the inlet mouth that maintains the water inside the pump body for the next start, thus preventing a siphon effect. To thoroughly fill the pump body and facilitate self-priming, in temporary installations with flexible pipe and without check valve, it is necessary to position the pipe next to the pump, making sure that it is lifted above the inlet mouth. Fig. 5 To eject water from the delivery mouth at the maximum suction height, it is necessary to restart the pump several times after the enabling of the device that prevents the pump from running without fluids. ADJUSTING THE WATER FLOW The IN@OUT motor-driven pump can generate noise, both in fixed and temporary installations, if the required water flow is too high; i.e. if the discharge pressure is below the minimum one specified on the nameplate. To reduce or eliminate noise, it is necessary to adjust the delivery gate. Attention: do not run the IN@OUT motor-driven pump manually for more than five minutes if the supplies to which it is connected are closed. A prolonged operation of the pump without water replacement may dangerously increase the temperature and pressure. If the water inside the pump is overheated due to a prolonged operation with low flow, it is necessary to stop the pump before opening the gate. Wait for the pump to cool down before restarting or refilling it.
