STEAM WITH
1.Fill tank with water; open relief valve to purge air from top of tank. Check for plumbing leaks.
2.Push control switch, located on the control box, to activate the steam valve and thermostats. Check steam valve for operation; the valve solenoid should “click” to open valves when operating switch is pushed “on”. The tank circulating pump, if present, should also operate. Check thermostat settings. The temperature limiting device is set at 200°F. Temperature setting: The operating thermostat is set at the factory at approximately 130°F and the upper operating thermostat is set at approximately 125°F. Adjustment may be made by turning the operating thermostat dial to the desired temperature.
3.Push the operating switch, located on the control box, to “off” before opening manual
main steam supply valve. This will allow condensate that has collected in the supply line to drain through the trap installed in front of the steam valve. When the steam supply line is free of condensate, push operating switch to “on”, opening the electric
4.Open nearby hot water tap to maintain a flow of water through tank when starting up units. Observe condensate flow at the receiver or other collection site to verify satisfactory flow. Regulate flow of water through tank to allow steam valve to cycle off and on, and check operation of unit.
MAINTENANCE
1.A preventive maintenance program should be established to assure a long,
2.Scale will normally form in the tank during operation and will accumulate on the bottom of the tank. The scale is formed from the natural chemicals in the water that precipitate out during the heating cycles. Some water supplies contain more of these chemicals than others, and the scale buildup will occur more rapidly. Other factors affecting the scale buildup are the amount of hot water used and the temperature of the water. The more hot water used, the more fresh water containing the
CAUTION
The relief valve is a primary safety device.
3.It is required for safe practice to operate the temperature and pressure relief valve once a year by lifting the lever briefly. If the valve does not open and close properly when testing, it must be replaced.
4.The temperature limiting device and thermostat temperature sensors that extend into the water in the tank may become coated with scale, depending on the type of water in your area. This coating will affect accuracy of sensors and can allow water temperature to exceed the desired limits. These controls should be removed from tank and inspected at necessary intervals. Remove scale if present.
WARNING!
To reduce the risk of electrical shock injury or death, on control systems using 120 volt external power, be certain switch is off and power disconnected before work is performed on this heater.
