WATER FEED SYSTEMS

CONDENSATE RETURN SYSTEMS

Chromalox condensate return systems are used wherever condensed steam can be collected for reuse in the boiler. Significant energy can be saved by returning condensate to the boiler. The condensed water is free from corroding minerals and carries a substantial amount of heat which does not have to be replenished.

IMPORTANT: Vacuum breaker is required whenever using a conden- sate return system.

Installation — Wiring

A.Check the voltage of the motor before making the wiring connection. Some Chromalox boilers are supplied with dual voltage systems. The motor should always match the voltage of the control circuit.

B.The motor circuit should be wired into the pump control located on the boiler. See boiler instruction sheet for wiring diagram.

C.All electrical wiring should be done by licensed electrician.

D.Be sure to use the proper wire. Electrical wiring to boiler

should be in accordance with National Electrical Code or local wiring code following wiring diagram supplied.

Plumbing

A.Connect water line to tagged fitting on the motor and pump assem- bly control feeder.

B.Interconnecting piping between boiler and condensate return system should be installed with a minimum of 90˚ bends or other restrictions.

MAINTENANCE

WARNING: Hazard of Shock. Disconnect all power before working on boiler.

Chromalox Electric Steam Boilers are designed for years of trouble-free performance. To establish a good preventative maintenance program, we suggest the building maintenance man or engineer familiarize him- self with these simple rules:

1.The use of specific boiler cleaning compounds cannot be rec- ommended. We do recommend that a reputable firm of water treat- ment engineers be consulted regarding conditioning boiler water. Proper selection must be made of a compound to prevent damage to copper sheath heating elements.

2.The sight glass should be checked daily to ensure the boiler has ade- quate water.

3.A monthly inspection should be made of internal wiring. All elec- trical connections should be checked for tightness.

A check for water or steam leaks should also be made and any loose fittings immediately tightened.

4.If boiler is equipped with Solid State Auxiliary Low Water Cutoff, every four months the probe should be checked for deposits and cleaned, if necessary. This is accomplished by removing inspection plate, removing the probe (with a standard sparkplug wrench) clean- ing and replacing.

Note: The system will not operate if the boiler is using distilled, demineralized or deionized water. At the same time, one of the bot- tom heating elements should be removed. If scale has begun to form, all elements should be cleaned and boiler drained and flushed.

5.IMPORTANT: The Manufacturers’ Data Report enclosed within the instruction sheet is very important and must be put in a safe place. You may be called upon to produce it by a state agency.

INSTRUCTIONS FOR ELEMENT REPLACEMENT WARNING: Before installing your new elements, be sure the McDonnell-Millerlow-watercut-off is operating perfectly and the float chamber and lower equalizer column are completely clear of sludge or other foreign matter.

Failure to do this may cause the immediate burnout of the new ele- ments.

All elements are thoroughly checked before shipment. The manu- facturer cannot be responsible for burnouts caused by a faulty low-water cut-off.

The lower equalizer column can best be examined by breaking the unions on either side and then visually and manually examining the pip- ing with your fingers or probes to see if it is clear and clean.
