5. ATTACHING FITTINGS & HOSES TO YOUR PUMP & FILTER

There are several ways to hook up hoses to your filter and pump and the best way will depend
on your set-up. Some pumps have female threads only (inside), some have male threads only
(outside) and others may have both or none. There are parts included in CARTON 2 which will
allow for set-up with virtually any style of pump. Below are the options available for hook-up
based on the threads that your pump has.

First, cover the threads on the straight
fitting 

(G)

and thread it into the slide valve

which you have attached to the filter’s
“TO POOL” opening (see Figure 16).
Attach the 6’ hose 

(B)

to the fitting you just

threaded in and clamp in place using hose
clamp 

(D)

. The free end of this hose should

be attached to the thru wall return using
another hose clamp (see Figure 17).

There should be at least one hose
fitting provided with your pump (or that
you may need to purchase separately),
which you will thread into the second
slide valve which has been threaded
into the bottom of your skimmer OR
into your pump (see Figure 18a & 18b).
Cover the threads of that fitting with
Teflon tape before screwing it into the
opening on the second slide valve.

Now it’s time to attach the flex pipe with connection fittings 

(C)

to your

filter and pump. Keep in mind that the hose is bent so that the pump will
accept the ‘higher’ part and the filter will accept the ‘lower’ part of the
connection. Check the flex pipe with connection fittings to ensure that
o-Rings are inside (see Figure 19). Lubricate o-Ring with o-Ring Lube
(sold separately) prior to installation. 

NOTE:

If you have a SIDE-MOUNT PUMP, you will NOT need to
attach this piece to your filter as the pump is already
connected.

NOTE:

If you have a pump that has NO THREADS then you will
need to purchase additional items to set up your new
filter system. You will need to get a 

3’ hose (1-1/4” or

1-1/2” depending on the size your pump accepts)

to

attach directly onto your pump’s outlet as the threaded
fitting provided will not fit and 

an elbow fitting is

necessary 

to thread into the female threads in the filter

“FROM PUMP” port to attach your hose. Please
remember you will need additional 

hose clamps

to install

with this method (see Figure 20).
