General Precautions

Attention
1. Follow the instructions to set a comfortable water
temperature and avoid overheating.
2. Please don't stack anything near the heat pump
that can block air flow to the inlet or exhaust area,
or the efficiency of the heater will be reduced
and/or stopped. For unit clearance information,
see Figure 2.
3. Please do not put hands into the outlet of the heater,
and do not remove the screen of the fan at any time.
4. If there are abnormal conditions such as noise,
smell, smoke, or electrical leakage, please switch off
the heater immediately and contact the local dealer.
Don't try to repair it yourself.
5. Do not use or stock combustible gas or liquid such
as thinners, paint and fuel close the heater in order
to avoid fire.
6. The piping between the pool and the heater should
be less than 30 ft (9.1 m) long, or heater performance
may suffer.
Safety
1. Please keep the main power supply switch far away
from children.
2. If a power outage happens while the heater is running,
the heater will restart automatically when power is
restored. Please switch off the power supply when
there is a power outage, and reset the temperature
when power is restored.
3. Please switch off the main power supply in the event
of lightning and stormy weather to prevent machine
damage from a lightning strike.
4. If the heater is stopped for a long time, please cut
off the power supply and drain water completely from
the heater by opening the union of the inlet pipe.
Special Attention
Please read this instruction manual carefully and operate
strictly according to the user manual before starting the
heat pump, otherwise the heat pump may be damaged or
cause you unnecessary harm.
This product is only for heating swimming pool or spa
water, and cannot be used for other applications.
Inlet and outlet water nozzles are not designed to bear the
weight of external pipes. Support the piping independently.
APPROVED
UNCONTROLLED DOCUMENT IF PRINTED
Make sure power is turned off before opening the case and
performing service work.
1. The heater must be installed by a qualified electrician.
2. Set heating temperature within the recommended
range to maximize comfort.
3. Keep the air inlet and exhaust free from obstructions.
4. This heater has a power-off memory function.
5. When the ambient temperature is at or below 32°F
(0°C) make sure the main power switch is turned off
and all water is drained from the heat exchanger.
6. Never place your hand or any other object into the air
inlet or exhaust of the heater.
7. If you see, hear, smell or otherwise sense anything
unusual (such as abnormal noise, smell, smoke, or
electrical leakage) switch off the main power switch
immediately and contact your local dealer installer.
8. Do not attempt to repair the heater yourself.

2. WATER CHEMISTRY

NOTE: Corrosive water causes damages which will not
be covered under warranty.
Chemical imbalance can cause severe damage to your
heater and associated equipment. Maintain your water
chemistry according to Table A. If the mineral content
and dissolved solids in the water become too high, scale
forms inside the heat exchanger tubes, reducing heater
efficiency and damaging the heater. If the pH drops below
7.2, this will cause corrosion of the heat exchanger and
severely damage the heater. Heat exchanger damage
resulting from corrosive water will not be covered by
the warranty.
For your health and the protection of your pool equipment,
it is essential that your water be chemically balanced. The
following levels must be used as a guide for balanced
water.
A CAUTION: Free chlorine must not exceed 5 ppm
which can damage the heater and is not covered under
warranty.
• Occasional chemical shock dosing of the pool or spa
water should not damage the heater providing the
water is balanced.
• Automatic chemical
chlorinators are usually more efficient in heated
water. Unless controlled, they can lead to excessively
high chlorine levels which can damage your heater.
• Further advice should be obtained from your pool
or spa builder, accredited pool shop, or chemical
supplier for the correct levels needed for your pool.
