Supply Compartments

Supply compartments are located behind an access door on the top left side of the machine front. The door can be opened by turning the door latch as shown in Figure 16.

The supply compartments are numbered 1 – 5, from left to right as viewed from the front of the machine.

Turn latch either direction to open supply door.

Installation

To connect external supplies, use the following procedure:

1.Connect tubes to supply inlets by pushing each tube over inlet lip. Tubes should fit snugly onto supply inlets. When seated completely, tube ends should contact rear of machine.

2.Tightness of fit will dictate whether or not hose clamps are necessary. No. 8 hose clamps are suitable.

Electrical Connections for Chemical

Injection Supply Systems

A stainless steel box at the rear of the machine houses a terminal strip which furnishes supply output signals for the chemical injection supply pumps. See Figure 18 for examples of applicable decals.

Terminals SUPPLY 1 through SUPPLY 8 provide 100-120VAC fused at 500mA. These terminals may be used to provide signals to the chemical injection system but must not be used to provide power to the pump. Do not attempt to increase fuse rating as this may cause damage to the washer-extractor’s circuitry.

An external chemical injection system requiring 200-240VAC can be powered through LINE 1 and LINE 2 on the external supply terminal strip on PVQ and PVT models. Any chemical injection system used with PVM, PVN, and PVP models must be powered by a separate independent power source.

Any injection system pump which requires 110VAC must be powered by a separate external power source.
