VII. Testing
1. Inspection before use
A. Check installation of the whole machine and the pipe connections
according to the pipe connecting drawing;
B. Check the electric wiring according to the electric wiring diagram and
earthing 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 1 minutes earlier than the compressor;
D. After the swimming pool heater starts up, check for any abnormal noise
from the machine.
VIII.Precautions
1. Attention
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;

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;
