heater near a suitable inside drain. Outside drains are subject
to freezing temperatures which can obstruct the drain line.
The piping should be at least ¾” I.D. and pitched for proper
drainage. (Figure 2.)
All condensate drain lines and T&P valve drains must be
piped separately and routed to an adequate drain. To protect
the Watter$aver’s outer finish, do not pipe drain lines into
the drain pan.
GENERAL INSTALLATION
WARNING
Failure to follow the instructions in this installation, op-
eration, and maintenance manual will release the manu-
facturer from any liability for any water damage in con-
nection with this water heater.
1. Select the proper installation site for the Watter$aver and
unpack it in the location where it will be installed.
IMPORTANT: The Watter$aver must not be installed
outdoors, in a corrosive environment, or in an area where
leakage of the tank or plumbing connections will
damage adjacent areas or lower floors of the structure.
For best results, make certain the unit is placed on a
level surface.
2. Use a ¼” nut driver to loosen the screws around the base
of the shroud and remove it from the water heater. it is not
necessary to remove the screws as the holes in the base of
the shroud are slotted.
3. Remove the screws from the shroud and separate the
halves.
4. Install plumbing to the tank in accordance with local
plumbing codes. Ensure plumbing connections will allow
the installation and removal of the shroud after all plumbing
is complete (See “Water System Piping.”)
5. Install primary and secondary condensate drain lines to
the evaporator pan and route to an adequate drain. If a drain
is not accessible, the installer can use a condensate pump
(sold separately) or install ECR’s Watter$aver Condensate
Management System. Contact the factory for more informa-
tion.
CAUTION
Do not apply power to an empty or partially filled water
heater. This can result in serious damage to the tank
and destroy the heating elements and will void the war-
ranty.
