INSTALLING CONDENSATE DRAIN
Poorly or improperly installed condensate drains can se- riously interfere with the operation of this refrigerator, and result in costly maintenance and product losses. Please follow the recommendations listed below when installing condensate drains to insure a proper installation:
1.Never use pipe for condensate drains smaller than the nominal diameter of the pipe or
2.When connecting condensate drains, the
3.Always provide as much down hill slope (“fall”) as possible; 1/8" per foot is the preferred minimum. PVC pipe, when used, must be supported to main- tain the 1/8" pitch and to prevent warping.
4.Avoid long runs of condensate drains. Long runs make it impossible to provide the “fall” necessary for good drainage.
5.Provide a suitable air break between the flood rim of the floor drain and outlet of condensate drain. 1" is ideal.
6.Prevent condensate drains from freezing:
a.Do not install condensate drains in contact with
b.Where condensate drains are located in dead air spaces (between refrigerators or between a refrigerator and a wall), provide means to prevent freezing.The water seal should be insulated to prevent condensation.

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
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.

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 - Three times daily for 46 minutes.The number of defrosts per day and the dura- tion of the defrost cycle may be adjusted to meet condi- tions present at your location.
ACCESS TO TX VALVES & DRAIN LINES
MECHANICAL - Remove the product from the bottom deck pan.Remove pan.Remove refrigeration and drain access pan- els (labeled). TX valve (mechanical only) and drain are lo- cated under each access panel at end of the case.
ELECTRONIC (Remote Only)
ELECTRONIC EXPANSION VALVE (Remote Only)
A wide variety of electronic expansion valves and case controllers can be utilized. Please refer to EEV and con- troller manufacturers information sheet. Sensors for elec- 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.
