Synergy 4040 - Synergy Sit Shower Shave Kit - Manual (Page 21)

3. With the vehicle running at idle and at its normal operating temperature, you can increase the heat of the
water coming through the shower by setting a higher idle on the vehicle.
4. If the water coming through the shower is simply too hot, turn the heater on in the vehicle or turn the
vehicle off completely and just use the residual heat of the heat exchanger to heat the shower water.
5. **WARNING** If at any time you turn the shower head to the “off” position, know that the water
sitting in the heat exchanger at that time will be continuously heated and will become very hot. Be
careful of this “hot spot” in the shower line when you turn the shower head back to the “on” position. It
is for this reason; we recommend not turning the shower head to the “off” position when using the
shower. Just keep it running until finished with the unit and turn the pump off.
6. The 12V pump features a 70 psi internal pressure switch which will trigger and turn the pump off if the
shower head is turned to the “off” position and 70psi of pressure is built up in the system. The pump
will automatically turn back on once the shower head is turned back to the “on” position.
