Valve Inspection; Winterizing Procedure - SHURflo Brix Series Manual

VALVE INSPECTION

Some concentrates after prolonged periods of contact without regular sanitizing, may cause the valves to
become stiff or clogged with pulp and/or particulates. If a situation of this type is suspected, valve
cartridges (4) can be removed for inspection.
1. Turn off water supply valve and relieve pressure. Remove each assembly by loosening the screw
holding the cartridge. Turn the cartridge and then pull it out of the housing (Pliers may be required).
Note inlet and outlet arrows molded on the pump housing for proper orientation of the respective valves.
Placement of concentrate valves in housing (Left side shown).
2. Disassemble each cartridge individually. Do not confuse inlet and outlet components. Inspect the
"Duck Bill" valves for tight seal in closed position. Valves should have quick action when pressed open
between the fingers, and material should not be hard or stiff.
NOTE: Valve kit (# 94-402-02) is available for in field replacement, contact your SHURflo
distributor for information. Complete instructions are included with each kit.
3. Reassemble each cartridge so that the valve support is not holding the valve open. Lubricate the
serrated surface of the valves and o -rings with an NSF listed food grade lubricant. Reinsert the
appropriate valves into the housing, turn back into position and tighten the screw. Be aware that the
valves may turn, allowing the support to hold the valve open, when reinstalling in the housing.
4. Sanitize and recheck for even (time) stroke in both directions of piston travel.

WINTERIZING PROCEDURE

If a BRIX pump is subjected to temperatures below freezing, with either concentrate or water within the
pump chambers, severe damage to the pump body may occur.
procedures be performed whenever the pump could be subjected to freezing temperatures.
1. Sanitize the system as outlined (ref. page 6), including the concentrate line to the dispenser. However,
DO NOT perform Step: 7 "Product Purge" on the system.
2. Turn off the city water source valve and relieve pressure. Remove all the fittings (Inlet/Outlet) from the
pump body and allow the solution to drain completely from the tubing.
It is advised that the following
