THE SMART SOLUTION FOR ENERGY EFFICIENCY Vertical Stack R e v. : 1 1 / 0 9 / 1 2 Water-Loop Heat Pump Applications Commercial Water Loop Applications - Commercial systems typically include a number of units connected to a common piping system. Any unit plumbing maintenance work can introduce air into the piping system; therefore air elimination equipment is a major portion of the mechanical room plumbing.
CLIMATEMASTER WATER-SOURCE HEAT PUMPS Vertical Stack R e v. : 1 1 / 0 9 / 1 2 Ground-Loop Heat Pump Applications Flushing the Earth Loop - Upon completion of system installation and testing, flush the system to remove all foreign objects and purge to remove all air. Antifreeze - In areas where minimum entering loop temperatures drop below 40°F [5°C] or where piping will be routed through areas subject to freezing, antifreeze is required.
THE SMART SOLUTION FOR ENERGY EFFICIENCY Vertical Stack R e v. : 1 1 / 0 9 / 1 2 Ground-Water Heat Pump Applications Open Loop - Ground Water Systems - Shut off valves should be included for ease of servicing. Boiler drains or other valves should be “tee’d” into the lines to allow acid flushing of the heat exchanger. Shut off valves should be positioned to allow flow through the coax via the boiler drains without allowing flow into the piping system.
CLIMATEMASTER WATER-SOURCE HEAT PUMPS Vertical Stack R e v. : 1 1 / 0 9 / 1 2 Flow Regulation - Flow regulation can be accomplished by two methods. One method of flow regulation involves simply adjusting the ball valve or water control valve on the discharge line. Measure the pressure drop through the unit heat exchanger, and determine flow rate from. Since the pressure is constantly varying, two pressure gauges may be needed. Adjust the valve until the desired flow of 1.5 to 2 gpm per ton [2.0 to 2.

Step 2: Attach Flex Hoses. Let the universal ends of the hoses hang inside the cabinet for now. (Figure 22). Note: Be sure the valve handles are in a position that enables them to be opened and closed. Check the swivel ends of the hoses (Figure 21). Gaskets must be in the hose for proper seal.
CLIMATEMASTER WATER-SOURCE HEAT PUMPS Vertical Stack R e v. : 1 1 / 0 9 / 1 2 Step 3: Attach to the Chassis. Slide the chassis part way into the cabinet. Match the WATER IN hose to the WATER IN tube on the chassis and the WATER OUT hose to the WATER OUT tube. Tighten the swivel connection keeping the copper tube parallel to the sides of the chassis, then tighten the hose to the copper making sure the hose hangs straight without twisting or turning (Figure 23).
