Premier2 Owner’s Manual
control is inoperative. Turn off all power to the unit, including auxiliary heat, and then turn it
back on. If the light remains continuously on or off call your WaterFurnace dealer.
DHW Limit
A sensor monitors the temperature of your hot water tank. The light will come on if the
temperature is above 130
°
F (54
°
C). At this time your unit’s hot water system will be de-
energized to prevent excessive temperatures. Don’t worry; hot water operation will resume
when the tank cools off. This is not a fault condition, and the unit does not require resetting.
DHW Pump Switch
When the pump switch is off, your unit’s hot water system is disabled, and
DHW OFF
status light will be lit. This switch may be used when the water heater is being serviced or
replaced. This switch must be turned off when water flow from the water heater to the
Premier2 unit is turned off or disconnected. Damage to the pump may otherwise occur.
What kind of safety controls does my
unit have?
Your WaterFurnace Premier2 unit is equipped with safety controls which are designed to
protect the unit in case of improper airflow, water flow or refrigerant charge. These safety
controls should not be bypassed by anyone. Doing so may void the warranty.
How do I maintain my system?
Caution: Before you perform any maintenance to your system,
turn off all electrical power to the unit. There may be separate
supplies— one for the unit and one or two for the auxiliary heat.
Filters
• Check your filters every 60 days. A dirty filter will cause your unit to work harder than
necessary, waste energy and may cause premature component failure.
• To achieve optimum performance and economical operation, change your “replaceable
type” filter if you see a buildup of dust or dirt.
• If you have opted for a permanent electrostatic filter, wash it with a garden hose at least
every 60 days. When placing the filter back in the slot, be sure that the arrow on the
filter frame points toward the Premier2 unit.
• After a new or clean filter is in place, press the
RESET FILTER
key on the thermostat.
• Never operate the unit without a filter; this will void the warranty.
