Installation Guide

08 09
DO NOT operate the appliance if water ceases to flow during use, if the outer case
or cover is loose or if the unit is not working properly.
If the unit leaks or does not heat properly, disconnect the unit.
ISOLATE the electrical and water supplies before removing the cover and before
proceeding with installation or servicing.
NEVER OPERATE THIS HEATER WITHOUT THE COVER!
WATER AND PLUMBING REQUIREMENTS
DO NOT USE PVC, CPVC or plastic supply lines directly to the unit. A 16” copper or
stainless steel pipe must be connected to the heater and then adapted to a different
material such as (CPVC, PVC or PEX PLASTIC).
Be sure to clean the pipes before connecting the heater to the main line. Clean all
the impurities of the pipe, allowing water to flow for a few minutes, check for leaks.
Any residue or dirt in the pipes may cause internal damage to the unit.
Connect the isolation valve at the entry inlet pipe of the heater and make sure you
install a rubber washer. Do not apply excessive force to tighten connectors. A
safety release valve must be fitted in the supply pipe.
We recommend installing a sediment filter before the entry of water to the heater.
Hard water or water with high levels of minerals and alkali can cause damage to
this unit. When this is the case, we recommend the use of a (non-salt) water
softening system.
The provision of a service stop valve in the cold supply pipe will assist in the event
of any subsequent servicing or maintenance.
These heaters are of the closed type (closed system with no ventilation pressure)
suitable for fitting to the normal input of cold water with a maximum of 94 PSI (6.5
bar). They must be fitted with a pressure valve adjacent to the entrance.
