VII.Testing
1．Inspection before use
A．Check installation of the whole machine and the pipe connections according to the
pipe connecting drawing;

12
B．Check the electric wiring according to the electric wiring diagram; and bonding
connection.
Ｃ．Make sure that the main machine power switch is off
Ｄ．Check the temperature setting.
E．Check the air inlet and outlet.
2
．
Trial
Ａ．The user must “Start the Pump before the Machine, And Turn off the Machine
before the Pump”, or the machine will be damaged.；
Ｂ．The user should start the pump, check for any leakage of water; and then set
suitable temperature in the thermostat, and then switch on power supply.
Ｃ．In order to protect the swimming pool heater, the machine is equipped with a time
lag starting function, when starting the machine, the blower will run 3 minutes
earlier than the compressor.
D．After the swimming pool heater starts up, check for any abnormal noise from the
machine.
VIII. Precautions
1Attention
A．Set proper temperature in order to get comfortable water temperature; to avoid
overheating or overcooling.
B．Please don’t stack substances that can block air flow near inlet or outlet area, or the
efficiency of the heater will be reduced or even stopped.

13
C．Please don’t put hands into outlet of the swimming pool heater, and don’t remove
the screen of the fan at any time.
D．If there are abnormal conditions such as noise, smell, smoke and electrical leakage,
please switch off the machine immediately and contact the local dealer. Don’t try
to repair it yourself.
E．Don’t use or stock combustible gas or liquid such as thinners, paint and fuel to avoid
fire.
F．In order to optimize the heating effect, please install heat preservation insulation on
pipes between swimming pool and the heater. During running period of the
swimming pool heater, please use a recommended cover on the swimming pool.
G．Connecting pipes of the swimming pool and the heater should be ≤10m, or the
heating effect of the heater cannot be ensured.
