1General information

￿WARNING • Before using product, read and understand instructions.

•Save these instructions for future reference.

•All work must be performed by qualified personnel trained in the proper application, installation, and maintenance of steam systems and/or boiler water systems in accordance with all applicable codes and ordinances.

•To prevent serious burns, wear heat resistant gloves when opening and closing steam valves, or handling hot equipment.

•To prevent serious burns, the internal pressure of the trap must be 0 psi (0 bar) before servicing.

•To prevent serious personal injury from steam pipe blow down, connect a temporary pipe between the steam pipe opening and a drain, or stand at least 100 ft. (30 m) from the front of the pipe opening.

•To prevent property damage, personal injury, or death, cap off the gate valves if they are not connected to a drain and when they are not in use for test or pressure relief.

Failure to follow this warning could cause property damage, personal injury, or death.

This manual is intended to cover installation, operation, and maintenance procedures for Lochinvar’s Hot Water Generator Systems. Since each unit is built to meet customer specifications, instructions may not be specific to every system.

If questions are not answered by this manual, or if specific installation, operation, and/or maintenance procedures are not clearly understood, contact Lochinvar for clarification before proceeding.

These Hot Water Generator Systems are designed for indoor use only, unless otherwise required by design specifications. Each unit requires at least two feet of clearance around and above the unit. It should be located on a level surface (no more than one-half degree of slope), capable of supporting the total weight of the unit when filled to capacity.

The unit should be mounted to the floor following applicable architectural and local code requirements for the specific installation site. Note: Tanks do not come standard with floor tie downs.

The high quality enamel paint, applied to the jacket of the unit, will provide years of protection against corrosion. If it is necessary to clean the outside of the unit, a mild cleaning agent should be used that will not damage the paint.

For all piping connections, the use and/or type of joint compound or sealer on the joints should be determined by referring to local codes, accepted standards, and/or the requirements of the installing contractor.

Lochinvar’s Hot Water Generator Systems are ideal when boiler capacity is sufficiently sized to cover potable hot water demand and provide source water for hydronic heating systems. Hot Water Generator Systems use steam or boiler water as an energy source and can provide high recovery rates, making them an economical water heating system for end users.
