BYPASS MANIFOLD
Clean the bypass strainer and orifice weekly, using
the following guidelines:
1. Remove the strainer. Clean and re-install. DO
NOT over-tighten strainer.
2. Remove the cap. Remove the orifice, using a
3/16" Allen wrench (the 3/16" Allen wrench is
provided with Part #66-945280, the bypass
maintenance kit).
3. Re-install the cap and run the unit with the water
pump ON for 15 seconds to flush out the bypass
manifold.
4. Remove the cap and re-install the cleaned orifice,
using the 3/16" Allen wrench. Tighten orifice just
enough to seat. DO NOT over tighten. Re-install
cap. DO NOT over-tighten cap.
NOTE: If o-ring seals leak, replace them. If
strainer is damaged, replace strainer.
CHECK VALVE (SOLUTION OUTLET)
Inspect the check valve whenever doing service on
the chemical pump or if flow problems occur in the
chemical system:
1. Remove the check valve. Be sure the small o-
ring for the seat comes out with the check valve.
2. Remove the seat, using a 5/16" Allen wrench.
3.
Check the Teflon seat for debris or wear. Clean
or replace Teflon seat if needed.
4. Clean the poppet and spring, inspect for wear or
damage, and replace as needed.
5.
Re-assemble the check valve. Start the seat by
hand, tighten using a 5/16" Allen wrench. DO
NOT over-tighten seat.
NOTE: Improper seating of the check valve
poppet, damaged spring or o-rings will cause
poor operation of the chemical system.
6. Lubricate the o-rings with o-ring lubricant
Part #05-008035 and reinstall.
CHEMICAL PUMP
The only repairs which the chemical pump may
require is the replacement of the diaphragm or check
valves. To replace the diaphragm, unscrew the cover
from the body. When replacing the diaphragm,
lubricate the outer edges of the diaphragm with o-ring
lubricant Part #05-008035 and reassemble. To
replace the check valves, unscrew the check valve
caps. Replace the check valves and reassemble,
using new o-rings.
DO NOT attempt to re-use o-rings once the check
valves have been removed. See the “Illustrated
Parts Listing” for a parts break-down on the chemical
pump.
