d. Press the ON/OFF button on the remote controller. The water pump will start when the

time reaches the TIMER ON setting and the heat pump will start 60 seconds after this

by going to the MAIN menu and selecting UNIT status to view water inlet and outlet,

refrigerant pipe and ambient air temps.

e. With the water pump running, check for water leakage and check for optimum water

ow. Adjust water ow by adjusting bypass valves until water ow through heater is

sufcient.

f. After the unit runs for a few minutes, check whether the air discharged by the fan is

noticeably cooler than the ambient air. Another way to determine if the heater is working

correctly is to view MAIN MENU>UNIT STATUS. Check to see if the WATER OUT temp

is higher than the WATER IN temp. If no cold air check or the water in and out temps

are the same check the refrigerant gauge on the heater to ensure there is a refrigerant

charge in the unit. Check also the INLET WATER TEMP is lower than the HEAT TEMP

set point.
