INSTALLATION

• The pump must be installed and serviced by a suitably qualified person to avoid hazards. Incorrectly installed or tested equipment may fail, causing severe injury or property damage.
• These instructions are a guide only. Should you the installer or owner of the product be unfamiliar with the correct installation or operation of this product you should contact a suitably qualified person for advice.
• Do not connect the system to a high-pressure or mains water system.
• This pump is not intended for use by persons (including children) with reduced physical, sensory, or mental capabilities, or lack of experience and knowledge unless they have been given supervision or instruction concerning the use of the appliance by a person responsible for their safety.
• Children should be supervised to ensure that they do not play with the pump.
• The LeisureTime Poll Pump is electrically connected. Ensure that it is isolated from the electrical supply during installation and any subsequent service work.

Plan the position of the pump

• a. Have enough ventilation to keep the ambient temperature below the motor’s rated ambient temperature whenever the pump is running. If installed in an enclosure/pump house, the enclosure must have adequate ventilation (200q. cm min, inlet & outlet) and air circulation. Allow 200mm to keep the rear of the motor clear.
• b. Have adequate floor drainage to prevent flooding and be protected from excess moisture.
• c. Be solid, level, rigid, and vibration-free.
• d. To reduce vibration and pipe stress, bolt pump to mount. Fixing holes accept 12mm fasteners.
• e. Be within 2m of a power outlet for electrical connection (refer to AS/NZS 3000 for rules regarding the connection of electrical equipment in pool zones).
• f. Allow adequate access for servicing pump and piping.
  LEISURETIME Swimming Pool Pump Owner’s Manual

Piping: For best performance, allow pump suction inlet height to be as far below water level as possible and allow the use of a short, direct suction pipe with minimum bends (to reduce friction losses).

• a. Use only Australian Standard PVC pressure pipe. For best performance use at least 40mm diameter pipe for all connections to the pump. Never use a suction pipe smaller than pump suction connections (40mm) and use larger pipe for long suction distances.
• b. To avoid stress on the pump, support both suction and discharge pipes independently. Place these supports as close to the pump as possible.
• c. To avoid a strain left by a gap at the last connection, start all piping at the pump and run pipe away from the pump.

Pool Outlets

• a. The pump suction system must protect against the hazard of suction entrapment or hair entrapment/entanglement. The pool outlet piping must be by the latest AS1926.3 standard.
• b. Suction outlet covers and skimmers must have been tested and found to comply with the latest AS1926.3 standard or ASME/ANSI specification for Suction Fittings.

Electrical

• Do not use extension leads as they are unsafe in and around the Pool Zone.
• Hazardous voltage. Can shock, burn or cause death.
• To avoid dangerous or fatal electrical shock, turn OFF the power to the pump and remove the plug from the outlet before working on electrical connections.
  • a. Electrical installation shall be by the national wiring rules (AS/NZS 3000) taking into account its ratings (Class I, IPX5). The pump is supplied with a standard Australian 10 amp plug and 2 meters of cord. Select the correct Pool Zone for installation.
  • b. An RCD with the maximum rated residual current of 30mA is required for the power supply to the pump. Additionally, if a suitable socket outlet is not available a weatherproof socket must be installed by an electrician in a suitable location. RCD tripping indicates an electrical problem. If RCD trips and will not reset have a qualified electrician inspect and repair the electrical system.
  • c. Incorrect voltage can cause fire or seriously damage the pump and void warranty.
  • d. Voltage at the pump must not be more than 6% above or 10% below motor nameplate rated voltage or the pump may overheat, causing overload tripping and reduced component life. If the voltage is less than 90% or more than 106% of the rated voltage when the pump is running at full load, consult the power company.

Equipotential bonding

• If equipotential bonding is required, connect all metal parts of the swimming pool or spa structure and to all electrical equipment, metal conduit, and metal piping under the wiring rules. Run a wire from the equipotential bonding terminal on the pump (bottom, left motor bolt with serrated washer) to the pool bonding structure.
• This pump is classified as; Double Insulated to the Water Circuit.

Priming the pump
It is not necessary to lubricate the oring. The original equipment O-ring contains a permanent internal lubricant.

• a. Before removing the trap lid, SWITCH OFF POWER SUPPLY to pump.
• b. CLOSE SHUT-OFF VALVES on suction and discharge pipes, if present.
• c. Remove the trap lid (turn anti-clockwise).
• d. Fill the trap tank with water.
• e. Check the lid o-ring and sealing surface, ensure there is no dust or debris on either, and replace the lid (turn clockwise to tighten by hand only – no wrenches!).
• f. Open the shut-off valves on the suction and discharge pipes, if present.
• g. Release all air from the filter, pump, and piping system (refer to filter owner’s manual). In a flooded suction system (water source higher than the pump), the pump will prime itself when suction and discharge valves are opened and the air is released.
• h. Switch the power to the pump to start.
• i. Pump should start to prime now. Priming time will depend on the vertical height of the suction lift and the horizontal length of the suction piping but is generally between 30 seconds to 3 minutes under normal installation conditions.

Should the pump, not prime, ensure that all valves are open, the lint trap is clear of debris and suctions and the suction pipe end is submersed in water, and there are no leaks in the suction pipe. See the troubleshooting guide.

• NEVER run the pump dry. Running the pump dry may damage seals, causing leakage and flooding. Fill the pump with water before starting the motor.
• Freezing conditions will damage the unit, as water expands as it freezes. Ensure that the pump is located so that it is not prone to freezing, or ensure that the product is disconnected and dried of water during cold conditions.
• Trapped air in the system can cause an explosion. Ensure all air is out of the system before operating or testing equipment.
• Fire and burn hazards. Modern motors run at high temperatures. To reduce the risk of fire, do not allow leaves, debris, or foreign matter to collect around the pump motor. To avoid burns when handling the motor, let it cool for at least 20 minutes before trying to work on it.
• Small children using the pool must ALWAYS have close adult supervision.
• Pump suction is hazardous and can trap and drown or disembowel bathers. Do not use or operate the pump, pool/spas if a suction outlet cover is missing, broken, or loose. Follow the guidelines below for a pump installation that minimizes risk to users of pools and spas.
• NEVER tighten or loosen the trap lid while the pump is operating.

OPERATION

Solar Operation

Solar pump installation
The Leisure Time Pool Pump can be used as a Solar Pump. There are two typical solar configurations; as a separate system, where the pump is plumbed separately to the filtration system, OR as a boosted system running from the filtration system.

Separate System

1. Only use the LTP pool pump in this configuration, not the LTPS pool pump. The LTP pump has an integrated basket which adds protection against debris blocking the system.
2. Locate the pump as per the instructions on pages 6-9.
3. The pump must be installed as per Australian standards. Use two sections, with separation and covers complying with AS1926.3.
4. Install the included ‘clacker’ on the outlet of the pump. The purpose of the ‘clacker’ is to provide protection against water running backward through the pump rapidly and spinning the impeller backward.
5. A check valve must be installed on the outlet of the pump between the pump and the solar input. The check valve shall allow a drain down of the solar pipes. A 6mm hole can be drilled into the flap of the non-return valve to achieve this.
6. Complete installation instructions as per solar heating system guidelines.

Boosted System

1. Only use the LTPS pool pump in this configuration, not the LTP pool pump. The LTPS pump is designed as a solar booster pump.
2. Locate the pump as per the instructions on pages 6-9.
3. The pump is to be installed after the filter.
4. A bypass pipe shall be installed between the pump suction and solar heating outlet.
5. Install the included ‘clacker’ on the outlet of the pump. The purpose of the ‘clacker’ is to provide protection against water running backward through the pump rapidly and spinning the impeller backward.
6. A check valve must be installed on the outlet of the pump between the pump and the solar input. The check valve shall allow a drain down of the solar pipes. A 6mm hole can be drilled into the flap of the non-return valve to achieve this.
7. Complete installation instructions as per solar heating system guidelines.

SERVICE & MAINTENANCE

• To avoid dangerous or fatal electrical shock hazards, turn OFF the power top pump and remove the plug from the power outlet before working on the pump.
• Do not operate the pump with the trap basket missing or damaged.

It is essential for the longevity of the pump that regular service and maintenance be carried out. The LeisureTime Pool Pump incorporates high- velocity moving parts and pumps water containing harsh pool chemicals. Some parts will wear during normal operation and the expected life of the pump.

Follow the instructions below to clean the trap:

1. Switch off power to the pump, close valves in suction and discharge, and release all pressure from the system before proceeding.

2. Remove the trap cover (turn counterclockwise). If necessary, tap handles gently with a rubber mallet.

3. Remove the strainer basket and clean it. Ensure all holes in the basket are clear, flush the basket with water, and replace in trap with a large opening at the pipe connection port (between ribs provided). If the basket is replaced backward, the cover will not fit on the trap body. To clean the transparent cover, use water and neutral soap only. Do not use solvents.

4. Clean and inspect the lid o-ring; reinstall the trap. Clean the O-ring groove on the trap body and replace the cover.
   To help keep the cover from sticking, tighten your hand tight only.

5. Prime pump (refer to priming instructions).
