InstallationsClearanceAccess to the unit for service purposes should be provided at installation. All 1/2 through 5 tonconfigurations require an 18" (457mm) surround clearance from other mechanical and electricalequipment (where shown) to enable panel removal from the unit for service/maintenance ability.Some local codes may require a greater service clearance than listed here. Check all coderequirements prior to unit installations.Water Pipes Connection1. Installation of water pipings should be designed in the way that winding upward and downwardplacement are reduced as much as possible.2. Flexible hose is recommended to be installed between unit and system piping. This will reducevibration and prevent pipeline leakage effectively.3. It is recommended to install shut-off device on the supply and return of the system, the unitmay be isolated during service or maintenance situation.4. Keep sufficient water pressure in the system to ensure water flow rate.5. A water strainer must be used on an open loop system to keep debris from entering the unitheat exchanger and to ensure a clean system.6. The water pipe must be insulated to prevent generation of condensate water.Drainage Method1. Install proper trapping to the equipment.2. When designing the condensate trap for the water-source system, it’s important to consider theunit’s draw-thru design requiring negative pressure trapping.3. It is imperative to maintain water in the trap and not allow the trap to dry out during the hotseason. Keeping trap primed always that will ensure flowing water properly.4. The unit should contain a dual ¼ to 12-inch pitch toward the drain connection. This will insureproper drainage of the unit.Min. 457mm clearance457mm(4-sides)Top ViewReturn AirTop ViewReturn AirSupply AirReturn AirLeftFrontSupply Air457mm(4-sides)CorridorSupply AirTypical Installation9GEHC-PRC001-EN
Duct Design for Noise ControlNoise ControlA water source heat pump is typically located in, or very close to the occupied space. Becausethe unit includes both compressor and fan as those with sound source components, properacoustical material shall also be considered during an architectural design. Most of the problemsassociated with equipment homing noise could be avoided by selecting and locating unitsproperly. Additionally, acoustic modeling can be used to predict space acoustical performance anddetermine cost effective design to meet a specific noise requirement. There are, however, somegeneral recommendations as a guideline of noise control for designing water source heat pumpsystems.Typical Sound PathsThere are primarily three different types of sound paths:1. Airborne: This is a path where sound travels with, or against, the direction of airflow. In a HVACsystem, sound travels along with this type of path throughout ductworks or air plenum.2. Breakout: This typical path is typically associated with sound breaking out and transmittingthrough duct walls to space.3. Transmission: This is a path where sound travels throughout the ceiling, floor and walls.Ductwork InstallationFor water source heat pump that uses ductwork design, in whatever of supply air and return airdistributions are critical against noise control in an occupied space. Typical installation with anexample below helps to keep noise control effectively. At least two perpendicular elbows along with supply air duct Lining the first 5 ft. (1.5m) at inner surface of supply air duct and length away of the fan discharge. The first tee is placed at least two duct diameters downstream from the fan discharge. Design supply air grilles in multiple locations. Design with low air velocity inside air duct. Isolate air ducts, water pipes and electrical connection out of unit vibration.Unit Installation1. The best method of obtaining acceptable sound level is to place units at proper locations, forinstance, inside a false ceiling or in an unoccupied area.2. The unit must be suspended with isolators and maintained about 2.5 meters between units inorder to avoid transmitting vibration noise.3. Avoid installing units adjacent to hard surfaces without sound wave reflection.4. For serving sensitive area, one inch thickness of insulation is recommended adhesive to thebottom surface of unit. This field supplied insulation should be sized in twice of the unit footprintfor absorbing noise effectively while unit in operation.Flexible jointFlexible jointReturn air grillewith filterSupply air grille10GEHC--PRC001-EN
