Refrigeration

REFRIGERANT TYPE

The standard refrigerant will be R-22 unless otherwise specified on the customer order. Check the serial plate on the case for information.

PIPING

The refrigerant line outlets are located under the case. Locate first the electrical box, the outlets are then on the same side of the case but at the opposite end. Insulate suction lines to prevent condensation drippage.

REFRIGERATION LINES

LIQUID SUCTION

3/8" O.D.

5/8" O.D.

NOTE: The standard coil is piped at 5/8" (suction); however, the store tie-in may vary depending on the number of coils and the draw the case has. Depending on the case setup, the connecting point in the store may be

5/8", 7/8", or 11/8". Refer to the particular case you are hooking up.

Refrigerant lines should be sized as shown on the refrig- eration legend furnished by the store.

Install P-traps (oil traps) at the base of all suction line ver- tical risers.

Pressure drop can rob the system of capacity.To keep the pressure drop to a minimum, keep refrigerant line run as short as possible, using the minimum number of elbows. Where elbows are required, use long radius elbows only.

CONTROL SETTINGS

See the “Case Specs” section of this guidebook for the appropriate settings for your merchandiser. Maintain these parameters to achieve near constant product tempera- tures. Product temperature should be measured first thing in the morning, after having been refrigerated overnight. For all multiplexing, defrost should be time terminated. Loadmaster valves are not recommended. Defrost times should be as follows: OFF CYCLE - One time daily for 110 minutes.The number of defrosts per day should never change.The duration of the defrost cycle may be adjusted to meet conditions present at your location.

ACCESS TO TX VALVES & DRAIN LINES

tronic expansion valves will be installed on the coil inlet, coil outlet, and in the discharge air. (Some supermarkets require a 4th sensor in the return air). Case controllers will be located in the electrical raceway or under the case

THERMOSTATIC EXPANSION VALVE LOCATION

This device is located on the same side as the refrigera- tion stub. A Sporlan balanced port expansion valve model is furnished as standard equipment,unless otherwise speci- fied by customer.

EXPANSION VALVE ADJUSTMENT

Expansion valves must be adjusted to fully feed the evapo- rator. Before attempting any adjustments, make sure the evaporator is either clear or very lightly covered with frost, and that the fixture is within 10°F of its expected operat- ing temperature.

MEASURING THE OPERATING SUPERHEAT

1.Determine the suction pressure with an accurate pressure gauge at the evaporator outlet.

2.From a refrigerant pressure temperature chart, determine the saturation temperature at the observed suction pressure.

3.Measure the temperature of the suction gas at the thermostatic remote bulb location.

4.Subtract the saturation temperature obtained in step No.2 from the temperature measured in step No.3.

3. The difference is superheat.

5. Set the superheat for 5°F - 7°F.

T-STAT LOCATION

T-Stats are located within the electrical raceway. Refer to diagram below.

T-stats are located in the front electrical raceway and can be adjusted through the knockout hole without removing any panels.The sensing bulb is in the discharge air.

ESSS

T-stat is located in the rear electrical raceway and can be adjusted through the knockout hole without removing any panels.The sensing bulb is in the discharge air. If the op- tional front electrical raceway is installed, the T-stat is lo- cated in the font electrical raceway and can be adjusted through the knockout hole in the front closeoff without

7removing any panels.
