Water Flow Rate Adjustment; Maintenance - Panasonic DH-4NS3 Operating Instructions Manual

2. WATER FLOW RATE ADJUSTMENT

(1) How to adjust to maximum water flow rate.
Step 1: Push the Push On-Off Lever and select Wide Shower type on the Shower Head using the Shower Select Button
(refer Figure 1).
Step 2: Turn "Off" the Main Water Valve.
Step 3: Turn the Shower Head upward at waist height.
Step 4: Turn the Water Volume Knob to maximum volume position (refer Figure 2).
Step 5: Gradually "On" the Main Water Valve and adjust the splashing height (H) of the shower.
It is recomended to adjust the water splashing height (H) at 100 cm - 110 cm (approximately 3 L/min).
(If splashing height (H) is too high, hot water temperature will drop because of an excessive flow rate).
Note: 1. Pay attention to shower temperature when reducing the volume of water.
The shower temperature will become very hot if the water flow rate is too low.
2. Water Volume Knob is at maximum position at this stage (refer Step 4).
Please adjust it to suitable flow rate using the Water Volume Knob by turning it anticlockwise.
