5. c Recycled water system The difference from gas water heater it should not bring environmental pollution or have the installing problems in windy areas 3 lt The unit should not be installed in a limited air ventilation area or placed in a bush where it will block the air inlet These location deny the unit of a continuous source of fresh air When seasons changing it may stick leaves on the evaporator coil thereby reducing its efficiency and impact of its service life 4 When install a bypass it should be not exceed 30 of nominal flow rate 5 Must make Water level higher than the circulation pump location 6 Below picture show the minimum required distance on each side of pool heat pump unit Air inlet 7 Typically the pool heat pump unit should be installed aside the pools less than 7 5 meters distance If itis installed farther away the pipeline system will cause greater heat loss The most of pipeline are installed under ground although the pipeline system has to do thermal insulation but tunnels and the soil around will still occur heat exchange for example each 30 meters 15 meters to and from the pump 30 meters total unless the ground iswet or the water table is high A very rough estimate of heat loss per 30 meters is 0 6KW per hour 2000BTU forevery 5 C difference in temperature between the pool water and ground surrounding the pipe which translates to about 3 to 5 increase in run time
