Pre-Installation Check List

Before installing your cleaner, review and understand all warnings and safety information in this guide. Failure to follow these instructions or improper installation of the cleaner can result in damage to the pool finish or the vinyl liner, Pentair disclaims any liability for repairs or replacement to any of these structures or components of the customer’s pool.

Before installing the cleaner in a vinyl liner pool

Check liner closely for signs of deterioration or damage from age, chemicals, pool wall damage, etc. If any damage is found, have a qualified pool professional make all the necessary repairs. Also, if there are stones, roots, etc., under the liner, remove them before installing the cleaner.
Before installing the cleaner in a gunite pool or a pool that is partially or completely tiled:
Repair loose tiles and tighten any loose light rings.

Before installing the cleaner, clean your filter system

Make sure you have cleaned the filter, including backwashing, rinsing, and emptying all baskets. A clean system is necessary for proper cleaner operation and coverage.

Before installing the cleaner, understand cleaner coverage

The cleaner is designed to rid your pool of debris in approximately 4-6 hours. Less time could be needed, depending on the pool size. The cleaner was not designed to automatically clean steps or swimouts or to work under a solar cover. It was also not designed to do initial cleanup for a new pool or when opening your pool for the season.

AFTER installing the cleaner, make sure the cleaner is operating correctly

The cleaner may need some minor adjustments to make sure it is operating properly so there is no damage to the pool finish. Certain vinyl liner patterns are particularly susceptible to surface wear, pattern removal, ink rubbing off of, or serious scratches to the pattern caused by objects coming into contact with the vinyl surface, including automatic pool cleaners. Pentair is not responsible for any pattern removal, abrasions or markings on vinyl liners.

Disclaimer of Liability About your Pool and Cleaner

There are a multitude of factors that contribute to the life of your pool. These robotic pool cleaners are very passive products that will have no impact on pool life. Please be aware that over time, deterioration, discoloration and brittleness of any pool finish can be caused separately by, or in combination with, age, an imbalance in pool water chemistry, improper installation and other factors. Robotic pool cleaners will not remove or cause wear on “good” pool plaster. In fact, the opposite is true–pool plaster will eventually cause wear on the cleaner. The same situation holds true for vinyl-lined in-ground swimming pools, because vinyl liners are also affected by the environment and factors such as pool water chemistry, sunlight and the pool’s surroundings. Therefore over time, vinyl can become brittle and weak. In addition, vinyl- lined pools are affected by the workmanship, composition and installation of the liner and the workmanship and quality of construction of the supporting walls and pool base. These are all factors which can contribute to liner failure. The existence of any of these type of conditions in your pool is not caused by the use or operation of the cleaner. The manufacturer disclaims any liability for repairs or replacement to any of these structures or components of the customer’s pool. The pool owner must assume all responsibility for the condition and maintenance of the pool’s surface, water and deck.

Initial Setup

Before using the cleaner for the first time, complete the following steps:

1. STEP 1: Power Supply Placement Position the power supply at least 12 feet (3.5 m) from the edge of the pool. See Figure 1.

2. STEP 2: Unroll Communication Cable Unroll the cable and stretch it out completely so that is has no kinks. See Figure 2.

3. STEP 3: Connect Power Supply to Cleaner

4. Connect the communication cable to the power supply, ensuring the connector notch is lined up with the corresponding groove in the power supply. See Figure 3.

5. Turn the cable connector clockwise to lock the cable into the power supply. See Figure 3.

6. STEP 4: Connect Power Supply to Power Source Connect the power supply to the electrical source/outlet. See Figure 4.

7. STEP 5: Placing the Cleaner in the Pool

8. Be sure the power supply is positioned a minimum of 12 ft. (3.5 m) from the pool.

9. Lower the cleaner into the pool by the handle (see Figure 5).
   Note: Never lower the cleaner into the pool by the communication cable. This puts an unnecessary strain on the cable and could result in damage to the cleaner.

10. Gently tilt the cleaner from side to side or turn upside down to release trapped air. See Figure 6.

Once the cleaner is resting flat on the pool floor, continue to the next page for instructions on either manually starting the cleaner or setting a weekly schedule.

WARNING

ALWAYS ensure the cleaner is fully immersed in water before manually starting the cleaner or before setting a weekly schedule. Moving parts may injure hands or fingers and operating the cleaner out of water will immediately cause severe damage to the cleaner.  Do not operate the cleaner when there are people swimming in the pool. Communication cable can trip or entangle swimmers which could result in drowning.

Manually Starting the Cleaner

1. To manually start a cleaning cycle, ensure the cleaner is fully immersed in water and press the power supply’s ON/OFF button. The cleaner will run a two hour cleaning cycle and then automatically shut off.
2. To stop an active cleaning cycle, press the ON/OFF button while the cleaner is running.

Setting a Weekly Schedule

An automatic cleaning schedule may be set at the power supply each week. Ensure the cleaner is fully immersed in water before setting a weekly schedule, as the cleaner will always start when a weekly schedule is set. When the power supply is switched on, a cleaning schedule for the coming week is set by pressing the Weekly Schedule button as instructed below:

1. LED 1 – Cleaner will run a two-hour cleaning cycle every day (7 times per week). Press the Weekly Schedule button once to select this interval.
2. LED 2 – Cleaner will run a two-hour cleaning cycle every other day (3 times per week). Press the Weekly Schedule button twice to select this interval.
3. LED 3 – Cleaner will run a two-hour cycle every 3 days (2 times a week). Press the Weekly Schedule button three times to select this interval.

To reset a weekly schedule, press the Weekly Schedule button four consecutive times. If you do not press any of the buttons within the first 5 seconds after the power has been switched on, the cleaner will default to manual operation. While the cleaner is in weekly schedule mode, the appropriate Schedule LED will blink between cycles. At the end of the week the power supply automatically shuts off.

Choosing a Style of Filter Screen

The Prowler® 917 Robotic Pool Cleaner offers two styles of debris filtration. The filter basket is shipped with two mesh filter screens and two pleated screens installed. Two additional pleated screens are provided with the cleaner and are interchangeable with the mesh filter screens. Cleaner performance can be improved by using certain filter screens in certain situations and pool environments:

• Factory-installed mesh filter screens should be used when vacuuming larger debris from the pool. Larger debris is common when first opening a pool or after a strong storm.
• Ultra-fine pleated filter screens should be used in most situations when vacuuming smaller debris.

Both styles of filter screen are removed from and installed into the filter basket similarly. To remove and install filter screens, follow the appropriate instructions given in Periodic Filter Screen Cleaning on page 6.

Make sure the cleaner’s power supply is turned “OFF” and is disconnected from the electrical source/outlet before removing the cleaner from the pool. Moving parts may injure hands or fingers if cleaner inadvertently powers on during servicing.

Removing the Cleaner from the Pool

The cleaner will shut off automatically at the end of a cleaning cycle. Follow the steps below to remove the cleaner from the pool.

Ensure the power supply is turned “OFF” and disconnected from the electrical source/outlet before removing the cleaner from the pool. Operating the cleaner out of water will immediately cause severe damage and will result in loss of warranty. Do not leave the cleaner in the pool all the time.

• Disconnect the power supply cable from the electrical outlet and disconnect the cleaner communication cable from the power supply.

• Using the communication cable, slowly and gently pull the cleaner to the waterline at the edge of the pool until you can reach the handle. DO NOT lift the cleaner out of the water by the cable.

• Using the handle, lift the cleaner out of the pool. See Figure 7.
  Note: Never lift the cleaner out of the pool by the communication cable. This puts an unnecessary strain on the cable and could result in damage to the cleaner.

• Place the cleaner on the edge of the pool and allow excess water to drain from the cleaner body and basket.

•  Disconnect the communication cable from the power supply.

• Store the cleaner in a covered area with the communication cable coiled.

1. STEP 1: Open the Filter Cover When the filter cover is opened the filter basket handle will pop up. See Figure 8 and 9.
2. STEP 2: Lift the basket out of the cleaner body.
3. STEP 3: Empty the Filter Basket Open the latch at the bottom of the filter basket. This will release the bottom lid of the basket and dump much of the collected debris. See Figure 11.
4. STEP 4: Clean the Filter Basket Thoroughly clean the filter basket with a garden hose. See Figure 12.

Periodic Filter Screen Cleaning

It is recommended that you clean the filter screens at least once a month. Excess debris in the filter screens will restrict the suction power of the Prowler® 917 Robotic Pool Cleaner and reduce its effectiveness. To uninstall and clean the two removable filter screens, follow the instructions given below.

1. STEP 1: Remove the Filter Screen
2. Each filter screen and side of the filter basket has a number stamped onto it. Filter screens will only fit into the matching side of the basket. See Figure 13. Note: Only screens 1 and 2 can be removed from the basket. Screens 3 and 4 cannot be removed.
3. Using your thumbs, firmly press the top of screen 1 inwards to detach the screen from the basket. See Figure 13.
4. Gently remove the screen from the filter basket. See
5. STEP 2: Clean the Filter Screen Thoroughly clean the filter screen with a garden hose. See Figure 15.
6. STEP 3: Reinstall the Filter Screen Seat the bottom of filter screen 1 into side 1 of the basket, then firmly press the top of the screen outwards until it clicks into place. See Figure 16.
7. STEP 4: Clean Screen 2 Repeat all previous steps to remove, clean and reinstall filter screen 2.

Cleaning the Impeller

Always disconnect power to the cleaner before servicing, disassembly, or reassembly. Failure to do so could result in death or serious injury to servicemen, pool users or others due to electrical shock. Read all servicing instructions before servicing the cleaner. Every so often debris may become trapped in the Prowler® 917 Robotic Pool Cleaner’s impeller. To clean out debris trapped in the impeller opening, follow the instructions below.

1. STEP 1: Open the Filter Cover and Remove the Basket See Figure 17 and 18.
2. STEP 2: Remove Debris from Impeller Cover By hand, clean as much debris as possible from the opening of the cleaner’s impeller. See Figure 19. Sometimes the debris may become lodged deeper in the impeller where you can not reach it. If this is the case, proceed to the next step to remove the impeller cover.
3. STEP 3: Unmount the Impeller Cover Using a No. 2 Phillips-head screwdriver, remove the two screws that hold the impeller cover in place. These screws can be found in the bottom corners of the impeller cover. See Figure 20. Place the two screws to the side.
4. STEP 4: Remove the Impeller Cover Gently pull the impeller cover away from the cleaner body. See Figure 21.
5. By hand, remove any debris that has become trapped around the impeller.
6. Remount the impeller cover with two impeller cover screws.

Storing the Cleaner

Any time the cleaner will not be used for an extended period of time, such as during the winter, follow the storage guidelines below.

• Disconnect the power supply.
• Always coil the cleaner’s floating cable.
• Store the cleaner in a protected area out of direct sun, rain, and frost, at a temperature between 5- 45 °C / 41-113 °F.
