CHAPTER 5. OPERATION
5.1 INTRODUCTION
This Chapter provides the pre-operational checks, initial start-up and operating procedures for
the SmartPlate Water Heater.
WARNING
FLUIDS MUST BE GRADUALLY INTRODUCED TO THE UNIT.
FAILURE TO DO SO CAN CAUSE DAMAGE TO HEAT
EXCHANGER PLATES. WHEN UNIT IS EMPTY OR COLD, DO
NOT ADMIT HOT FLUID TO THE UNIT SUDDENLY. WHEN
UNIT IS HOT, DO NOT SHOCK WITH COLD FLUID.
CAUTION
Do Not operate equipment exceeding design conditions as
specified on the nameplate.
The SmartPlate must never be subjected to pressure greater than
the maximum differential pressure specified on the nameplate.
Sudden rises in pressure may cause leakage or damage to plates
or gaskets of double-wall models and damage single-wall heat
exchangers.
5.2 PRE-OPERATIONAL CHECKS & PROCEDURES
All SmartPlate Installation procedures provided in Chapter 2 must be fully completed prior to
performing Pre-Operational checks. In addition, the following items should be checked:
1. Ensure that external single-phase AC power at 120 VAC/60 Hz or 240 VAC/50 Hz is
properly connected to the ECS/SP Control Box.
2. Verify that the ECS/SP Temperature Controller setpoint and Over-Temperature Switch
alarm limit have been properly set using the procedures in Chapter 4 - ADJUSTMENTS.
3. Open the isolation valve in the cold water inlet line (Figure 1-1) to the SmartPlate Heater.
4. The air vent, located in the top of the manifold, allows air to escape during the fill process
(a hissing sound may be heard). If a hissing sound is not heard through the air vent, close
the air vent cap and then open it 2 full turns counterclockwise. Do Not remove the air vent
cap.
5. When the hissing sound from the air vent stops, carefully open the Pressure &
Temperature (P&T) Relief Valve to vent any remaining air.
6. Close the P&T Relief Valve when the heater is full.
