Resumen del manual
The primary indicator of this condition is little or no suction line superheat. Also, as the TXV is not holding back the required amount of refrigerant, there may be flash gas (high-pressure vapor) present in the liquid line; this is indicated by reduced liquid sub-cooling. Insufficient Condenser Water Flow: • Head pressure will moderately high to very high; • Suction pressure my be normal to slightly high; • Amperage will be higher than normal; • Liquid Sub-Cooling will be absent; the liquid line will be very warm or even hot to touch. When combined with high condenser water DT (see next bullet item), this condition is a prime indicator of insufficient condenser water flow; • Condenser entering-leaving water temperature difference (water DT) will be higher than normal. This condition is a prime indicator of insufficient condenser water flow; • Superheat will be high-normal to high. Explanation: Heat is not being removed in the condenser in quantities sufficient to produce appreciable amounts of liquid refrigerant. With no liquid seal occurring in the condenser, the liquid line.in essence. becomes an extended discharge line. Keys to diagnosis: very warm to hot liquid line, and a high condenser water Delta-T. INSTALLATION Placement of Heater Indoor Installation Every indoor installation is unique, therefore, there are no specific guidelines for this type of installation. For assistance, please contact AquaCal.s Engineering or Technical department at (800) 786-7751; they will assist you with your specific needs. Outdoor Installation Service and Operational Clearances: . Refer to recommended clearance drawings following this section. Allow 24" clearance between the heat collection surfaces and walls, fences, shrubs, or other objects. The heat pump requires large volumes of air moving over the heat collector. . Allow 5 feet of vertical clearance between the top of the heat pump and any roof overhang or other obstruction. This clearance prevents cold discharge air from recirculating back into the evaporator coils (recirculation would reduce the overall performance of the heat Pump). . Provide at least 30. open area in front of the main access panel. The electrical panel will need to be accessed during installation and service, so avoid any plumbing obstructions that will restrict easy access. Code Required Clearances: . In addition to the previously stated clearance requirements, follow all applicable local, state, and national requirements relative to spacing from other objects or equipment. Typical Installation Clearances 24 - Inches (Side) 24 - Inches (Rear) 24 - Inches (Side) 30 - Inches (Front) Rain run-off must be directed away from unit Overhang with gutter 5 ft. minimum clearance, overhead 2 ft. minimum clearance, rear 30” minimum clearance, front (No Scale) Front, Rear, and Overhead Front, Side and Rear Irrigation, Rainwater Runoff, and Landscape Features Place the heat pump away from rain runoff from the roof. A gutter or rain shield may be required on the roof edge above the heat pump. Relocate or adjust irrigation to avoid water spray directly onto the heat pump. Do not locate plant shrubs or bushes directly adjacent to heat pumps. Doing so will prevent proper air circulation into the unit, and may inhibit access to the heater when service is needed. Consult drawings above for proper clearances. Equipment Pad Requirements The equipment pad should be constructed to provide adequate drainage and support to the base of the heat pump (see Table below). The pad should be essentially level with just enough pitch to drain condensate and any other water away from the heater. Model Minimum Pad Size T135 36. X 42. T115 36. X 42. T65 36. X 42. Anchoring Heater to Pad Follow all relevant local, state, or national requirements regarding wind load anchoring (use huricane anchoring kit, part #STK0010). As necessary, contact AquaCal Technical Support, 800-786-7751, for assistance in determining best method of compliance. Plumbing Requirements Overview: When planning plumbing system layout, reference the plumbing schematics following this section as a guide to the sequence of equipment, valves, fittings, etc. The plumbing configurations for typical installations are diagrammed. In operation, it is imperative the heat pump receive water flow within the minimum-maximum ranges specified for the particular heat pump. Should the system installation under consideration not closely match any of the schematics, contact AquaCal Technical Support for advice and guidance: (800) 786-7751. Parts and Materials: Industry technology changes much too rapidly for AquaCal to specify, with exactness, any items outside and beyond the heat pump. What is specified is that the heat pump must be installed in accordance with all applicable local, state, or national codes & standards. Connection to Heat Pump: All TropiCal heat pumps come equipped with 2" PVC, plumbing unions. Connection to site plumbing is made via PVC solvent cement to the fe...
