Installation and Operation Manual
This manual is intended to cover installation, operation, and
maintenance procedures for Lochinvar’s SJS Storage Tank.
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.
Storage Tanks are designed for indoor use only. 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

architectural and local code requirements for the specific
installation site. NOTE: Tanks do not come standard with
floor tie downs.
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.
WARNING
Areas of potential danger:
1. All water lines, joints, and valves.
2. If the unit has been in operation, allow
the water in the heater and all
components and surfaces (tank surface,
water piping, etc.,) to cool before
starting any maintenance procedures.
3. Assure that all power to associated water
heating equipment has been shut off
and disconnected before attempting
any procedures.
WARNING
The combination of electricity and water
can pose a very dangerous situation.
Assure that all power has been shut off /
disconnected from any associated water
heater equipement before attempting any
installation or maintenance procedures.
