3.4.5 Post Installation Review
The water heater requires 220~240 VAC for proper operation.
Wiring size and connections comply with all local applicable
codes and the requirements of this manual.
Water heater and electrical supply are properly grounded.
Proper overload fuse or circuit breaker protection installed.
Understand how to use the User Interface Module to set the
various modes and functions.
Understand the importance of routine
inspection/maintenance of the condensate drain pan and
lines. This is to help prevent any possible drain line
blockage resulting in the condensate drain pan overflowing.
IMPORTANT: Water coming from the plastic shroud is an
indicator that both condensation drain lines may be blocked.
Immediate action is required.
To maintain optimal operation check, remove and clean the
air filter.
the atmosphere such as sulfur, fluorine, and chlorine. These
elements are found in aerosol sprays, detergents, bleaches,
cleaning solvents, air fresheners, paint, and varnish
removers, refrigerants, and many other commercial and
household products. In addition excessive dust and lint may
affect the operation of the unit and require more frequent
cleaning.
The ambient air temperature must be above -7ºC (For model
TNF190 is -5 ºC)and below 43ºC If the ambient air temperature
falls outside these upper and lower limits the electrical elements
will be activated to meet the hot water demand.

NOTE
3.4.1 Location
The flooring beneath the water heater must be able to support
the weight of the unit when filled with water (more than 286kg).
Located indoors (such as a basement or garage) and in a
vertical position. Sheltered from freezing temperatures.
Provisions made to shelter the area from water damage.
Metal drain pan installed and piped to an adequate drain.
Sufficient room to service the water heater.
Sufficient air for the heat pump to function,
the water heater must be located in a space >15m³, and must
have unrestricted air flow.
The unit cannot be placed into any type of closet or small
enclosure.
The site location must be free from any corrosive elements in
For optimal efficiency and serviceability, the following clearances
should be maintained: 800mm on the air inlet side, 800mm on the
air outlet side, 600mm in the back, and 600mm in the front.
