Mechanical Connections Refrigeration piping The equipment must be connected to a condenser—either a remote outdoor condenser or an indoor centrifugal condenser. Systems with remote outdoor or indoor centrifugal condensers will require discharge and liquid lines from the equipment to the condenser. Install all refrigerant lines in accordance with applicable industry guidelines as well as local and national codes and regulations. To size lines, see “Recommended line sizes” on page 20.
Recommended line sizes Equivalent length m (ft) Line type ACRD100, ACRD101 (OD) 15 (50) Discharge line (horizontal) 5/8 in ACR Discharge line (vertical) 1/2 in ACR Liquid line 1/2 in ACR 30 (100) Discharge line (horizontal) 5/8 in ACR Discharge line (vertical) 1/2 in ACR Liquid line 1/2 in ACR 46 (150) Discharge line (horizontal) 5/8 in ACR Discharge line (vertical) 1/2 in ACR Liquid line 1/2 in ACR Note: All refrigerant pipes must be straight ACR to have 565 psig or above MWP.
Connect refrigerant lines Be sure to use only clean, refrigerant-grade (ACR Type L) pipe and follow standard procedures for pipe size selection for air-cooled equipment. The maximum allowable equivalent length between the evaporator and condenser is 61 equivalent m (200 equivalent ft). Vertical runs (hot gas) require a trap every 6 m (20 ft) of rise.
Condensate pump The condensate pumps are factory-wired and piped internally to the condensate pan. The pumps are capable of moving liquid a maximum of 15.2 m (50.0 ft), which may include a maximum lift of 4.9 m (16.0 ft) as measured from floor level. For example, if your lift is 3 m (10 ft), you only have 12.2 m (40.0 ft) of usable run remaining. The pumps also use on-board condensate high level float switches, which are wired into the alarm input for local and remote alarm capabilities.
Routing the condensate pump drain line. Caution: Failure to properly route condensate drain line before operation could result in water damage. na2671a Top condensate pump drain routing Route the condensate drain line through the top or the bottom of the equipment to an appropriate drain. Note: Comply with all local codes when installing the condensate drain line to the drain system.
Leak sensor (optional) AP9325 na2760a Install one leak sensor (AP9325). To extend the leak sensor length, add up to three additional leak sensors (AP9326). na1584a AP9325 1. Connect the leak sensor to the equipment using the leak detector port as shown. na2676a Leak detector port 2. Position the leak sensor inside or outside the equipment. Note: Install leak sensors on a clean surface, and do not allow them to touch metal that is in an air stream. 3.
Adding a holding charge R-410A is a mixed refrigerant. When charging this equipment with mixed refrigerant, only liquid refrigerant must be charged. Caution: Failure to charge with liquid refrigerant only may damage the system. Note: The equipment must be charged only with R-410A. It is the responsibility of the installing contractor to provide sufficient refrigerant for a complete system charge during startup. Note: It is very important to make a note of the amount of R-410A used in this pre-charge.
