JETVAC®INSTALLATION MANUAL

INTRODUCTION

Congratulations on purchasing the JET-VAC automatic pool cleaner. The JET-VAC is

the easiest to install, most energy efficient automatic pool cleaner on the market.

The JET-VAC has a patented, built-in backup system that will move the unit out of

corners and away from other obstacles that tend to trap other pool cleaners. The unit

moves forward for approximately three minutes, then backs up and turns for

approximately one and one-half minutes, all the while vacuuming and sweeping your

pool in a random pattern. It is designed with fewer moving parts to give you years of

dependable, economical service. The JET-VAC is built with pride from the best

materials obtainable by skilled craftsmen, state-of-the-art machinery and is backed by a

three-year limited warranty that guards against defects in parts and workmanship

Like any other mechanical device, the JET-VAC should be routinely maintained. We

recommend that you have your JET-VAC checked periodically by your local JET-VAC

dealer.

For best results, your JET-VAC should be installed by a professional, but can be

installed by the consumer with some plumbing experience.

Thank you for choosing JET-VAC.You have made a wise choice!

AUTOMATIC POOL CLEANER

INSTALLATION PROCEDURES

BEFOREYOU START, PLEASE READ THIS ENTIRE DOCUMENT for important quidelines to assure

proper installation and care of your JET-VAC. JET-VAC pressure test sticks are available from the

factory or your JET-VAC Dealer.

The JET-VAC comes packaged in two separate boxes. One box contains the head and hose assembly,

and the other contains the booster pump. The JET-VAC needs a 3/4 h.p. booster pump to operate correctly.

You may already have a booster pump at your equipment pad. If so, proceed to the next section after the

Booster Pump Installation.

The JET-VAC is designed to clean swimming pools that have been pre-plumbed with a dedicated line

(pipe) that runs from its own booster pump to the wall of the pool. At that point, most pools have 1-1/2"

female threads. If the pool has 3/4" female threads, it will require the LW11A3 wall fitting, or the

3/4" MPT x 1-1/2" FPT Reducer Bushing.

QUICK DISCONNECTS:

Quick Disconnects are used at all important hose junctions. They are easily snapped on and off by

pulling back on the ring and twisting on or off. Give a tug at the connection to make sure it is snug.

MENDER NUTS:

These plastic nuts provide a gripping hold over hose ends that have been pushed down over various

fittings and connections. With the hose pushed tight over the end of the fitting or connection, grasp the hose

in one hand and slide the mender nut toward the hose, twisting until firmly in place over the hose end.

PRESSURE TEST STICK - USE JET-VAC TEST STICK ONLY

In order to assure correct operation, is is necessary to adjust the water pressure after cutting the feed

hose to fit your pool size. To accomplish this, you will need a 0-60 P.S.I. pressure gauge with a 1/4" M.P.T.

connector, a JET-VAC Pressure Test Stick, part No. JV-P8.

BOOSTER PUMP INSTALLATION:

Installation of the booster pump requires both electrical and plumbing. The electrical connections should

be completed by a licensed electrician in accordance with applicable electric codes. Remember: the booster

pump is not self-priming and must be installed PAST the filter pump and PRECEDING any chlorinating

device (if applicable). Booster Pump details are packaged in Booster Pump Box. Please note: a booster

pump is required for the JET-VAC to work. If you do not have an existing booster pump, you should have

purchased a JET-VAC unit complete with pump. If you do not have a booster pump, please contact your

dealer immediatly or call Customer Care at 1-800-831-7133.

WALL FITTING INSTALLATION:

The wall fitting is the outlet for the water supply from the booster pump to the pool.

 1. Flush the system by first turning ON filter pump (for at least 30 seconds) and then turn ON booster

 pump, until stream of water appears clear.

 2. Turn OFF both pumps and clock.

 3. Check the filter screen inside the wall fitting to make sure it is free of debris. (It is important to

 check and thoroughly clean the wall fitting filter screen periodically.)

 4. Remove the wall adaptor from the wall fitting and screw adaptor by hand into the dedicated line.

 Turn until tight.

 5. Take the wall fitting and twist lock the wall fitting into the wall adapter 1/4" turn; to a snug fit.

3. Attach the "Sweep Hose" end of the feed hose to the wall

fitting. (Hereafter, attached refers to attached to the wall

fitting). See Photo #1.

4. With a loose grasp on the feed hose, walk around the

circumference of the pool to find the point that is furthest

from the wall fitting and remove slack from the hose, but

do not stretch the hose. See Photo #2

5. While maintaining a grasp on the attached hose, use a

sharp knife to cut the dark blue hose (marked with a

bright-colored label reading "cut this section only") at the

point where the end of the hose would touch the edge of

the pool. See Photo #3. Take both hose sections and go

to the wall fitting.

*Note: After you cut the dark blue hose to size, evenly

space the two JV57 float moving them so they divide the

remaining section into three equal parts.

6. Secure with your foot or knee the dark blue attached

hose. Remove the dark blue piece of hose from the white

section at the mender nut and discard the severed piece

of dark blue hose.

7. At the mender nut, attach the removed white hose to the

severed end of the attached dark blue hose. See Photo

8. Reverse hose ends (disconnect the sweep hose end of

the hose from the wall fitting and reconnect the other

white hose end to the wall fitting).

VINYL LINER POOLS - ADJUSTMENTS

IMPORTANT WARNINGS:

Some vinyl pools have a steep incline from the deep end to the shallow end, some simple adjustments to

the JET-VAC will help it climb up into the shallow end of the pool.

1. ALWAYS remove the JET-VAC Automatic Pool Cleaner before anyone enters the swimming pool.

2. ALWAYS have a licensed electrical contractor install the wiring for the JET-VAC Booster Pump. It must

be wired in accordance with a local and/or regional electrical codes.

3. ALWAYS disconnect the JET-VAC from the wall when back-washing or cleaning the filter system. When

you have finished and the pumps are OFF, remove the wall fitting first, then turn ON the filter pump. WAIT

ONE MINUTE, then turn ON booster pump to flush out the sweep line. Then turn OFF booster pump AND

filter pump. Remove and thoroughly clean filter screen inside wall fitting. Reassemble screen into wall fit-

ting and screw fitting back into wall. Adjust wall fitting so that the connector points up towards the water

surface.

4. ALWAYS remove wall fitting and JET-VAC when back-washing filter system. Be certain wall fitting screen

is clean before reinstallation.

5. ALWAYS remove JET-VAC and hoses when adding chemicals. Run filter to mix chemicals in water for at

least 30 minutes before reinstalling JET-VAC and hoses in water. CHEMICAL ATTACK WILL VOID THE

WARRANTY. Never pour concentrated chemicals on or near any part of the JET-VAC or hose assemblies.

6. ALWAYS store all parts of the JET-VAC and hose assemblies away from excessive heat or cold and direct

sunlight, when not in use.

6. The JET-VAC is not designed to clean up after new pool construction. Large amounts of grit or sand will

damage wheel bearings. Please manually vacuum the pool before installing the JET-VAC.

7. NEVER operate your JET-VAC without a booster pump. Your existing filter system cannot generate

adequate pressure.

1. Remove the transparent nose wheel (part #JV13) by removing the phillips screw and the

plastichub that the screw goes through. Turn the nose wheel upside down, with the flange

end of the hub up, reinstall the screw into the hub and screw securely. Check that it spins

freely and does not fall off.

2. Remove the phillips screw and nut that holds the stainless steel wheel (part #JV15) in place

and reinstall in the lower mounting position.

3. Loosen, but do not remove, the phillips screw that attaches the roller arm (part #JV12) to the

JET-VAC body. Place the JET-VAC on a flat surface and adjust the roller arm angle so that

the bottom of the stainless steel wheel (JV15) is 1/2" from the flat surface and tighten the

phillips screw securely.

4. Test the JET-VAC in the pool to verify adjustments. *Note: In some cases it may be necessary

to increase pressure to 27-29 PSI for added thrust.
