Washtech XP Service Manual - Installation
Installation
WARNING
Installer must be suitably qualified and ensure compliance with all codes and
standards including AS/NZS3500.1.
Failure to comply even partially with installation instructions may void the
warranty.
Positioning
Unpack machine, check for damage and complete delivery. Install machine on sound
waterproof self-draining floor and use adjustable feet to level machine.
Allow room for detergent to one side of machine or in adjacent cupboard. 20litre container
requires about 450H x 250W x 350D, but smaller containers are available from many
suppliers.
Benchwork
Refer Bench Details diagram.
In corner installations the front of the machine must face to the left of the corner.
In corner installations high or angled bench return off wall may clash with door handle.
Level and secure machine and benches. Adjust to ensure smooth travel of rack through
machine.
Water Supply
Hot water temperature
65°C ± 5°C
Connection
20
mm
(3/4" BSP Male)
Flow rate minimum
20 litres per minute
Consumption per cycle
2.6 litres approximately
Backflow prevention
DCV = Dual Check Valve fitted standard
Pressure
200-350 KPa = 30-50 Psi.
Above this range fit pressure limiter. Don’t use small diameter plastic supply lines especially
below this range when optional rinse booster pump may be required. FLUSH supply line
before connection. Poor quality supply or excessive water hardness may affect performance
or damage machine – filtration and/or softening is recommended.
Waste
40 mm gravity drain – refer point B on installation diagrams – run waste directly behind the
machine or through open base.
Power
15A 240V 50Hz via switched outlet adjacent to machine, which is supplied with cord set
including 15A plug. Machine may also be installed on 3 Phase, Neutral and Earth, 415V
50Hz 15A/ph, permanently wired via wall switch mounted adjacent to machine – refer
schematic diagram for this requirement.
Detergent
Insert detergent pump inlet hose into container of commercial low foam detergent. Open
machine door and switch machine on. Press and hold detergent prime switch behind front
cover until chemical flows into machine.
Rinse Aid
Insert injector inlet hose into rinse aid container. Check amount of fluid rising up inside
pipe during pulse at start of rinse cycle. Rotate adjusting screw clockwise to reduce flow
and anticlockwise to increase flow.
Installation Checklist
Complete attached Installation Checklist to ensure machine is installed and running
correctly, and operator is familiar with operating procedures.
Troubleshooting
If the machine doesn’t fill after switching on the power, check and ensure that the hot
water supply tap is open, water supply pressure is not below specification and Dual Check
Valve is not faulty and correctly installed (arrows on the dual check valve’s body specify
water flow direction).
