MAINTENANCE
6. add the appropriate cleaning solution to the unit.
For daily cleaning:
Dissolve a safe, non-toxic, non-
corrosive sanitizer into 1 gallon (3.7 L) of hot water and
pour into the well. allow to soak for a minimum of 15
minutes.
For removing lime and mineral deposits:
add water to
the well until the water is at the normal operating level or
covers the accumulated scale. add white vinegar to the
water so that the resulting solution is approximately 2-parts
vinegar to 5-parts water. Do not use flavored vinegar. allow
the unit to stand with the mixture in the well for an
appropriate period of time.
NOTE: The amount of lime and mineral content in the water
and how often the unit is operated in HOT Mode will
dictate how often the unit needs to be delimed. Units
used with water that contains high lime and mineral
content may require deliming on a daily basis. Product
failure caused by liming or sediment buildup is not
covered under warranty.
NOTE: The time required will vary depending on the solution
used and amount of deposits in the well. Heavy scale
buildup may require additional treatments
7. after cleaning, drain all expended solution from the unit
through the drain and the clean-out drain(s).
8. Thoroughly rinse unit with fresh water until discharge is
clear and all sanitizers have been removed and rinsed.
9. Upon visual inspection, if the Hydro-Heater tank is not
thoroughly clean, repeat steps 4–8 above.
10. Install the pipe cap(s) onto the clean-out drain(s).
11. Continue with step 5 of the “Daily Cleaning” procedure in
this section.
Helpful Hints for Maximum Performance in HOT
Mode
• Keep Hydro-Heater inlet and outlet strainers free of debris.
• always keep the perforated water baffle in place and free
of debris when operating in HOT mode.
• Delime unit regularly using a non-corrosive deliming
solution.
Cleaning the Condensing Unit
Perform the following procedure monthly to maintain proper and
efficient operation as well as prevent malfunction when
operating in COLD mode .
1. Remove and clean both sides of the louvered or grill-style
panels that are installed in the ventilation openings. Dirt
and dust build-up in the panels can restrict air flow to the
condensing unit and cause over-heating.
2. Clean the condenser coil cooling fins. Dirt, dust, and lint
build-up in the cooling fins will prevent proper cooling of
the refrigerant in the refrigeration system. This buildup will
cause inefficient operation and can lead to unit failure. Use
the following methods to clean the condenser coil cooling
fins:
• Vacuum the cooling fins.
• Brush the cooling fins vertically using a condenser coil
brush.
NOTICE: Use caution when brushing the
cooling fins, they are delicate and can be bent easily.
DO NOT use a wire brush.
Condenser Coil Cooling Fins
NOTE: Depending on the conditions of the installation site, this
cleaning procedure may need to be performed more
often or less often than monthly. Monitor the level of
dirt, dust, and lint buildup on the panels and cooling
fins, and make adjustments to the frequency of
cleanings as necessary.
