HIGH TEMPERATURE AIR TO WATER HEAT PUMP Accessing Additional Heat Pump Parts In addition to the Heat Pump, you will get 4 rubber anti-vibration pads for the unit to sit on as well as 2 brass thread adapters to convert the threads to NPT. Remove the main door located on the side of the unit (see below) and the parts will be located inside the unit.
HIGH TEMPERATURE AIR TO WATER HEAT PUMP Automatic Air Venting Automatic air vents should be installed on the system at all possible locations of an air lock. This is typically on top of the tank, on the outlet line of the heat pump, and at the highest point of the system.
HIGH TEMPERATURE AIR TO WATER HEAT PUMP Buffer Tank (water tank) Installation • The Buffer tank should be installed indoors and as close to the heat pump as possible (Maximum 50ft). • When there is a chance of freezing, glycol water mixture should be used in the buffer tank.
HIGH TEMPERATURE AIR TO WATER HEAT PUMP Installation of Indoor Heating Equipment • Indoor heating equipment such as fan coils, radiator heating or floor heating, should be installed in accordance with relevant regulatory requirements, engineering design drawings, and the manufacturer's installation instructions. •...
HIGH TEMPERATURE AIR TO WATER HEAT PUMP Note On Choosing Piping Sizes: These notes are based on Type L copper pipe to ASTM Standards & VIPERT™ piping to ASTM standards • The flow velocities are too high to use 1” PEX for the heat pump loop. Stick to 1” copper or 1.25” PEX pipe.
