Condensing Temperature Correction Factor Electrical Wiring The electrical installation should be in accordance with Discharge Line Temp. Discard the four mounting angles Figure 5, item 1. Model Voltage Height Depth Length Ship Wt. Values in table are based on 105°F condensing temperature. Common practice is to fabricate the trap using three 90-degreeells.
Fan cycling controls should be adjusted to maintain a minimum of five 5 minutes on and five 5 minutes off. Installation and Operations Manual General Fan Layouts Figure 11. CalClean should be applied liberally to entering air and leaving air surfaces of the finned area in accordance with the label directions. The hot gas exits the loop at the pan loop outlet header and enters the evaporator through the check valve assembly. Electrical protection must be provided for this transformer. Hot Gas Defrost Systems Hot Gas Defrost systems can be described as reverse cycle, re-evap.
The fan motor next to the header end of the condenser is the variable speed fan. Replacements within the first year of the warranty area available through the distributor; the second through fifth years, the purchaser must submit a proof-of- purchase of a compressor and supply it to Heatcraft Refrigeration Products Warranty Claims for reimbursement. Under no circumstances should the coil headers or return bends be used for moving these units. Any damages to the condenser due to excessive weight, pressure or vibration will not be covered by standard warranty. All controls and safety switch circuits properly connected per wiring diagram. Leg assembly horizontal airflow, models 008-016; 1-3 1.
All implied warranties are limited to the duration of the Express Warranty. With this extended compressor warranty, replacements are administered by an authorized compressor distributor only. This condition can be overcome in one of two following ways: 1. Model Voltage Height Depth Length Ship Wt. Because air temperature in some regions varies as much as 100 degrees from summer to winter, some means must be employed to keep the condensing temperature sufficiently high to ensure proper operation of the refrigerant expansion valve during low ambient operation, and also allow sufficient capacity so that excessively high condensing temperatures do not result during high ambient conditions.
Suction lines should be sloped towards the compressor at the rate of one 1 inch per ten 10 feet for good oil return. Advertisement Print version Many people prefer to read the documents not on the screen, but in the printed version. Fan motors are designed for continuous duty operation. The amount of subcooling will depend on the design and size of the heat exchanger and on the operating suction and discharge pressures. The factory installed wiring and piping must not be changed without written factory approval. Check carefully for concealed damage. It turns out to be a real dilemma when several virtual papers become unreadable after creating them in one processor but opening them in another, especially if they can make or break your scholastic or business career.
It is not limited to a single viewer. Enter the information as called for on the tag in order to expedite handling at our factories and prompt issuance of credits. Keep unit fan discharge away from any building air intakes. Installation and Operations Manual Table 1. These settings are approximate as they do not take into account variations in load.
See Tables 1, 2, and 3 for discharge and liquid drain line size recommendations for remote condenser selections. Put dry nitrogen through lines while brazing. Alternating Evaporator System In the alternating evaporator hot gas defrost system, a third line is taken off the compressor discharge line as the re-evap system. Liability for incidental and consequential damages is excluded. Holes are provided in the base runner for this purpose. Sound and structural consultants should be retained for recommendations. System must be thoroughly leak-checkedand evacuated before initial charging.
All of the condenser fan motors have sealed ball bearings. The contactor coil is 24 volts, 115 volts or 240 volts as ordered. In addition, a re- evaporator accumulator is used at the suction outlet of the evaporator. The amount of refrigerant that must be added to a system for winter or cold weather operation is determined by Tables 6, 7 and 8. Unit Location Units are designed for outdoor application and may be mounted on a roof or concrete slab ground-levelinstallation. As long as the software supports this format, regardless of the manufacturer the same work works , it can read the file s without a hitch.
