Working with electricity requires proper skills and knowledge – Installation of the unit
should be performed by someone who is familiar or trained in this trade.
We HIGHLY recommend that you hire the services of a licensed and qualified
“Electrician/Plumber” familiar with tankless water heaters installation.
IMPROPER INSTALLATION CAN CAUSE INJURY OR EVEN DEATH.
IMPORTANT: All electrical work and unit fixing to the wall should be completed
before connecting electrical wiring.
When you turn on the unit, extremely hot water could come out. Take proper safety
precautions to avoid being hurt or burned by water.
• DO NOT r estrict the flow of water enter ing the unit.
• 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 do 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 A ND 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 adaptedto a different
material s uch 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 re commend the use of a (non-salt) water softening
system.
• The provision o f a service s top 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 a djacent to the e ntrance.
