Pressure Relief

Instructions

Reference numbers used in these instructions correspond to parts included in Kit and are provided on page

1. Parts identified with an alpha character are user provided, already installed components or locations necessary to correctly complete these instructions.

SKIN INJECTION HAZARD

High-pressure fluid from dispense device, hose leaks, or ruptured components will pierce skin. This may look like just a cut, but it is a serious injury that can result in amputation. Get immediate surgical treatment.

Follow Pressure Relief Procedure in this manual, when you stop dispensing and before cleaning, checking, or servicing equipment.

Relieve pressure in system by using two wrenches working in opposite directions on pump element and pump element fitting to only loosen fitting.

NOTE: When loosening pump element fitting, do NOT loosen pump element . Loosening pump element will change the output volume.

Disassembly

NOTE: Unless otherwise noted, all illustrations show 2L pump models.

1.

Disconnect power source.

2.

Relieve pressure using Pressure Relief Procedure provided.

3.

For 2 Liter models only: use a strap wrench around reservoir (a) to turn reservoir 1/4 turn coun-

ter-clockwise (F

IG

For 4L or larger reservoirs : be sure strap wrench is positioned around the lower portion of the reservoir. Turn reservoir counter-clockwise approximately to full turns until it is loose enough to remove it from reservoir adapter.
