INSTALLATION AND OPERATION MANUAL
UPFLOW SWIMMING POOL CARTRIDGE FILTER
CARTRIDGE CLEANING INSTRUCTIONS
HARMSCO CARTRIDGES
May be cleaned and reused before replacement is necessary.
Cartridge cleaning is necessary only when flow falls below that required or
when pressure increase over start-up pressure exceeds 10 pounds.
INSTRUCTIONS FOR CLEANING CARTRIDGES
See Page 4 on how to remove and replace cartridge(s) for cleaning.
Remove rim gasket to prevent damage during cleaning.
Normal Cleaning Procedure.
Normal cleaning is done by using a pressure nozzle on the end of your garden
hose. Direct jet spray at cartridges on an angle to remove dirt.
Special Cleaning Procedures.
To be used only when normal procedure is insufficient to return cartridge to
normal filter runs.
Removing Oils From Cartridges. If oils coat cartridges and cause reduced flow, this
material may be removed by soaking cartridges in a solution of 2 lb.Tri-sodium Phosphate
to 10 gallons of water or a Tri-sodium Phosphate based product. Usually 12 hours soaking time
will break oil coating from cartridge. Enzyme products are known to release oils from cartridge
media and in some cases may eliminate the need for soaking. Tri-sodium Phosphate and
enzyme products are available at most swimming pool distributors and retail locations. Repeat
Normal Cleaning Procedure.
Removing Algae From Cartridges. If algae coats the cartridges and causes reduced flow,
soak cartridges in a solution of 2 lb.Tri-sodium Phosphate to 10 gallons of water. Add 1 pint
of swimming pool chlorine to kill the algae. Soak for one hour. Check pool chemistry for cause of
algae growth.
Removing Calcium Or Mineral Deposits. ***Caution*** Do not use muriatic acid on
cartridges until all oils have been removed as in step #1 above. Make sure all previously
used products have been thoroughly rinsed from cartridges.
If calcium deposits are present, perform operation #1 above. Rinse - then, in a solution of 1 part
muriatic acid to 20 parts water, soak until bubbling action stops. Use a plastic garbage
container or similar vessel. Check pool chemistry for high PH or Alkalinity. Repeat Normal
Cleaning Procedure.
The only exception to the above procedures are with the use of biguanides (i.e. Baquacil,
SoftSwim or other similar sanitizer). When using a biguanide, always soak the cartridge
with muriatic acid first (as described in #3), and then soak in Tri-sodium Phosphate and water,
(as described in #1).
Heed all manufacturer's posted instructions, warnings and cautions
when using any product.

TYPICAL INSTALLATION OF RESIDENTIAL POOLS
Where unit is being installed below water
level of the pool, it is necessary to pro-
vide valves as indicated in the drawing
as shown, so that the filter housing may
be opened without draining the pool.
To protect against electrolysis, all
metal components of the water circu-
lation and heating systems must be
connected by a wire to ground the entire
system.
Filter housings must be grounded
DO NOT STORE CHEMICALS NEAR FILTER HOUSING
TYPICAL INSTALLATIONS*
For Residential and Commercial Pools
SUGGESTED INSTALLATION (Fig. 1)
1. Install 1-1/2" "T" on the center nipple as
shown in figure 1.
2. Pipe water from discharge of pump to one
side of this "T".
3. Install a 1-1/2" x approximately 10" nipple
from other side of this "T" with 1-1/2"
valve at end of nipple.This is for draining
filter unit.
4. Install 1-1/2" elbow on the other nipple as
illustrated.This is the return-to-pool line.
SUGGESTED INSTALLATION (Fig. 2)
1. Install 2" thread to socket PVC elbows on
side of nipple marked inlet–Pipe water from
pump discharge to this elbow.
2. Install 2" thread to socket PVC elbow on
center nipple marked outlet.This is the
return to pool line.
3. Install 1" valve or cap on marked drain.
SUGGESTED INSTALLATION (Fig. 3)
1. Install thread to socket "T" on the side
nipple as shown in figure 3. Pipe water from
discharge of pump to one side of this "T".
2. Install nipple and valve in other side of this "T".
This is the drain for emptying filter housing.
3. Install thread to socket PVC elbow on
center outlet.This is the return-to-pool line.
SUGGESTED INSTALLATION (Fig. 4)
1. Install water pipe from the pump to flange
marked "inlet".
2. Pipe return-to-pool line flange marked "outlet".
3. Install valve in drain line to threaded

ASSEMBLY INSTRUCTIONS FOR
BKM BASE MODELS
Models: BF144 BKM, BF105 BKMSC and BF155 BKMSC are 2"
Models: BF42 BKM, BF84 BKM, BF126 BKM are 1-1/2"
Harmsco base kit models are adaptable to different swimming pool pumps.
STEP 1. Read instructions thoroughly and
familiarize yourself with parts. (Cartridge
cluster may be removed during assembly).
STEP 2. Install the 1-1/2" nipple (MPT x SLIP)
(#861B) into top of pump using teflon tape.
Slip the 1-1/2" S.S* clamp coupling (#861A)
onto the nipple, tighten bottom bolt only.
STEP 3.Turn filter tank upside down and
install 1-1/2" PVC elbow (SLIP x FPT)
