FILLING THE HEATER

1.Completely close the drain valve.

2.Open the highest tepid water outlet to allow all air to escape from piping.

3.The black plastic knob on the air vent valve must be opened two turns to allow air to escape from the system.

4.Open the valve to the cold water inlet and allow the heater and piping system to completely fill, as indicated by a steady flow of water from the open outlet.

ELECTRICAL INSTALLATION

1.Enter junction box with properly sized feeder leads.

2.Connect these power leads to wires enclosed in junction box with wire nuts.

3.All other electrical connections are made at the factory; therefore, no other electrical connections are necessary.

FINAL CHECKS

1.Check all connections for tightness.

2.Ensure that all the above steps are completed.

3.After the water is heated for the first time, monitor the water temperature as described in Section III, Quarterly Inspection.

SECTION III - SCHEDULED MAINTENANCE AND OPERATION

WARNING / CAUTION

Before performing any maintenance procedure, make certain power supply is OFF and cannot accidentally be turned on.

MAINTENANCE AND OPERATION

The water heater is automatic in its operation. It will maintain a full tank of water at the temperature setting of the thermostat. The water heater should not be turned on without first making sure that the tank is full of water and that all air has been released.

FREEZING

The tank should be fully drained in the event the electricity has been turned off and if there is danger of freezing.

MONTHLY INSPECTION – MIXING VALVE

NOTE: The mixing valve should be tested in conjunction with regular OSHA required shower/eyewash testing. These tests confirm that the equipment is safe and operational and also serve to purge potential bacteria laden water from the system.

1.Monitor temperature

a.Record all information on the Mixing Valve Inspection and Test Log, see page 11.

b.Using an accurate thermometer, turn on the shower/eyewash and record the maximum start-up spike temperature of the water.

c.After a few minutes of running, record the normal temperature.

d.If the temperature does not match required temperature (±3°F), recalibrate the mixing valve. See Section V, Service and Replacement of Parts, Re-Calibrate Mixing Valve.

2.Monitor flow rate

a.OHSA/ANSI recommends a potable water system maintain a pressure of 30-psig minimum with a flow rate of 20-GPM minimum to a shower head and 3-GPM minimum to an eye/face wash fixture.

b.One simple method of testing is to collect the water in a 5-gallon container. At the required flow rate, the shower head will fill the container in approximately 15 seconds and the eye/face wash will fill the container in approximately 15 seconds.
