Pegasus Whirlpool Kit
Midi-6 & Midi-8 Fitting Instructions
The Pegasus Whirlpool system from Whirlpool Express is a Hydro-massage
system which can be fitted to any shape or size of acrylic bath.
The Pegasus Whirlpool system has been designed to be able
to fit to any bath without putting any stress on the bath whatsoever.
Jets can be placed to give the customer both aesthetic appeal and maximum
hydromassage. To achieve this jets will usually be located laterally within
1.5" of the desired position, even when up against obstructions such
as bath legs - something which can not be achieved with conventional whirlpool
systems without placing alot of stress on the bath or modifying the manufacturers
legs.
Important Notes
To ensure that you get the best out of your whirlpool system, please take
the time to read these instructions fully before attempting to start to
fit the kit.
NB The Pegasus fitting tool ( definitely needed for in-situ conversions)
is available at GBP 10.00 Plus VAT
When gluing pipe to venturi and manifolds be sure that only the exterior
surface of the plastics are glued and not the pipework. Take care not
to allow glue to get into the interior surfaces or the pipework as this
will seriously reduce the performance of the whirlpool system.
When fitting the pump fixing bracket to baseboard of bath be sure to check
the length of the screws. The screws supplied are for 3/4" thick
encapsulated baseboards
Basic outline of fitting Procedure
1. Check the bath for damage and defects.
2. Fit Legs & pump to bath using Fixing Bracket and screws.
3. Determine Position of Jets, Suction & Controls taking care to look
for obstructions.
4. Determine the position of the On/Off button and Air control. Ideally
the Air control needs to be mounted on a corner of the bath to allow the
pipes to be fitted easily.
5. Drill the holes - Slowly and Carefully.
6. Install all the fittings onto the bath.
7. Connect the pipework between the manifolds and venturi ensuring that
all fittings are cleaned with MEK and that glue is only applied to the
external surfaces of the Manifolds and Venturi - Not to the inside of
the pipe or venturi. Ensure pipes are connected to the correct manifolds.
NB when gluing the rigid suction pipe, joints can be glued on both surfaces
to ensure adhesion.
8. Watertest the finished product before final installation of the bath.

Detailed Fitting Instructions
1. Checking the bath for damage - before drilling!
i) Carefully remove the manufacturer's wrapping and any cautionary labels
from the bath.
ii) Corners not cracked or broken.
iii) Check that the lip of the bath has been cut cleanly and is not chipped
iv) Rub the bath over with a dirty, wet duster looking carefully at places
where the dust collects in lines. Determine if these lines are scratches
which can be easily polished out, or worse, cracks caused by transit damage.
v) Check that the waste hole is central in the recess.
vi) Check that the tapholes are correct.
vii) Check that the bath is true and not warped.
viii) Check that all the legs and fixing brackets are present - including
screws.
 2.
Fixing the legs and the pump to the bath
i) Read through the manufacturers installation instructions for the bath
ii) Place a dust sheet on a table turn the bath upside down on this sheet
and fit the legs and feet to the bath carefully following the manufacturer's
instructions. Leave the bath upside down on the sheet and;
iii) Assemble the threaded bar to the Pump Mounting Plate and Pumpstand
using the nuts provided.
iv) Assemble the pump to the baseplate using the four nuts and bolts provided.
v) Assemble the outlet manifold and the suction inlet to the pump using
the special fixing brackets provided.
vi) Offer the pump up to the bath (still-upside-down) and find a position
where the pump is central and within the confines of the bath. Be careful
to take into account the length of the outlet manifold and any wooden
panels which may be subsequently fitted to the bath.
vii) Secure the pump and bracket to the bath using the five screws provided.
Important: the screws have been designed to secure the Pumpstand to baseboards
with a thickness of 3/4" - check the length of the screws against
the thickness of the baseboard before attempting to fix the pump stand
to the baseboard. A good guide to the thickness of the baseboard is the
length of the screws supplied to fix the legs to the bath! - if in doubt
use shorter screws. Under no circumstances attempt to fit the Pumpstand
to a bath manufactured from GRP - GRP Baths do not have baseboards.
 3.
Determine the position of Jets, Suction and controls.
i) The number of jets to be fitted and the shape of the bath will usually
determine the jet positions.
ii) Jets are normally equally spaced along each side of the bath but can
be fitted on any flat surface. See Fig. I.
iii) Ensure positions chosen allow sufficient room for the Venturi (watch
out for bath support legs) and that the Venturi will not interfere with
the sitting of the pump.
 iv)
The suction is best fitted toward the foot end of the bath (away from
the seat area). See Fig.1
v) The difference between the jets and suction fitting is important to
ensure that the maximum amount of water drains from the system after use.
See Fig. 1.
vi) The suction is the lowest fitting in the bath and should be placed
as low as possible on a flat surface. See Fig. 2.
vii) The centre line of the jets should be 60mm. above the centre line
of the suction. See Fig.1.
viii) Note that the water level will be some 35mm. above the centre line
of the jets. Check that the water level will be below the overflow. See
Fig. 1.
ix) Mark all the positions with either a chinagraph or a felt-tip pen.
 4.
Position the height of the Pump.
i) The centre line of the pump suction must be 15mm. below the centre
line of the jets See Fig.1.
ii) If the pump is too high, it will not prime. Too low and it will not
drain when the bath is emptied. Remember that the water hose is to be
connected to the water manifold. See Fig.1.
5. Position the On/Off Button and Air Control.
i) The on/off button and air control should be fitted to the top surface
of the bath.
ii) Check that there is enough space underneath the proposed location
of the On/Off and Air Control for the backnut and air manifold to seat
properly seat on the underside of the bath. Remember that the air hose
is to be connected to the manifold. See Fig. 3. Important : - Always allow
for access to the controls, especially the On/Off control
 6.
Drill the Holes.
i) Before drilling the holes, re-check all positions, ensure that the
bath legs, panel, pump, fixing battens, etc. will not obstruct fittings
or indented hose runs.
ii) Using a 50mm. hole cutter, drill the holes from the inside of the
bath,tacking care to prevent the drill from slipping. Important-Safety:
Always point the drill away from the body when drilling holes - never
drill towards your body without a body shield.
iii) Back file the holes with a small round handfile to clear any burrs
and unevenness left by drilling the hole.
iv) Clean off the excess pen marks and dust using a tissue dampened with
meths. Pay particular attention to clean immaculately around the holes
as dust may hinder the effectiveness of siliconing the wall fittings to
the bath!
7. Installing the whirlpool fittings onto the bath.
i) The clear water fixing tool is now required to install the fittings
to the side of the bath.
ii) Assemble an `O' ring to each of the Venturi and place a band of silicone
sealant around the wall fitting shoulder. See Fig. 7. Using the fixing
tool, fit the Venturi to the bath with the pipes at 45 degrees approximately
above horizontal pointing towards the pump, ensure the make-up washer
is in position and tighten wall fitting into Venturi. Important Note:
- do not overtighten as damage to the venturi could result
 iii)
Repeat the above operation for the remaining wall fittings.
iv) (The wall fitting with two holes in the face is the suction wall fitting.
)
v) Clean off any excess sealant.
8. Install Suction Elbow and Hose.
i) Place a bead of clear sealant around the shoulder of the suction wall
fitting and the flange of the suction elbow. Using the key from the Clear
water fixing tool, assemble the suction fitting. Important Note: do
not overtighten. See Fig. 5.
ii) Measure and cut to length the suction Pipe and glue to the suction
elbow and pump elbow using a recommended adhesive
iii) Clean off any excess sealant.
 9.
Connect Water and Air Hoses to Manifolds.
i) Starting at the jet closest to the pump, measure the length of water
and air hose required to connect the Venturi to the water and air manifolds.
Glue the hose to the Venturi using a recommended adhesive. Important
Note: - only glue the exterior of the Venturi - not the inside of the
hose!
ii) Hose should be taut but not stretched and with a fall either to Venturi
or pump without sagging. See picture on Page 1iii) Ensure water hose is
connected to pump manifold and air hose to air manifold.
(iii) Always use a mask when drilling as the dust can irritate throats
and may be harmful 
10. Fix Drain Line.
i) Cut the drain line to length
ii) Fit it to the pump using tubing nuts and olives provided. See Fig.
6.
iii) Cut the tube to length and secure the loose end to the suction elbow
11. Install Eyeballs and Locking Rings.
i) Place the spacers in each of the jet fittings on the bath
ii) Place the Eyeballs on top of these
iii) Using the Pegasus fixing tool secure the Eyeballs in position with
the retaining rings. See Fig. 7.
 12.
Fit Suction Cover.
i) Secure the suction cover to the wall fitting using the two screws provided.
13. Connect On/Off Button to Pump.
i) Push 3mm. bore clear hose onto button and to switch in terminal box.
Important Note: - Do not allow pump to run without water in the pump
as costly damage may occur
 14.
Clean and Test.
i) Ensure all debris is cleared from bath.
ii) Fill with water to a level of three inches above the jets
iii) Allow to stand for five minutes and then check to ensure that all
joints are watertight.
iv) Activate pump and re check all joints
v) Leave pump running for 20 minutes
vi) Turn pump off and continue to fill bath up to the level of the overflow.
Leave the bath stand for 30 minutes again.
15. Connecting to Mains Supply.
i) Connection should always be entrusted to a suitably qualified electrician
and carried out in accordance with Wiring Regulations.
ii) The control box supplied should be fitted under the bath 50mm. above
floorboard level to prevent ingress of water should flooding or water
leaks occur.
iii) Important Note: - Complete Instruction 13 before switching on mains
supply.
(1) Most baths nowadays are moulded from Acrylic which
is then back sprayed with chopped strands of GRP to reinforce the
acrylic and give it strength. A length of chipboard is then stuck
to the base to further increase the strength of the bath. This baseboard
may be encapsulated by a further coating of chopped GRP. If in doubt
as the material of the bath look carefully in the overflow and you
should see a good 3 or 4mm thickness of acrylic with a nominal 2-3mm
of acrylic reinforcing. If in doubt contact us before fixing
