Hot Water Generator Installation Instructions

General information
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.

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.
