Installing Condensate Drain
Poorly or improperly installed condensate drains can seriously 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
to prevent air leakage or insect entrance. Store plumbing system floor drains should be at least 14” off the center of the case to allow use of 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 maintain 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.
Refrigeration
Refrigerant Type
The standard refrigerant will be
specified on the customer order. Check the serial plate on
the case for information.
Piping for more than one case on a condensing unit is run underground with either common suction and liquid lines from the machine room or individual suction and liquid lines joined together in the machine room.
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
Refrigerant lines should be sized as shown on the refrigeration legend furnished by the store.
Install
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.
For refrigerators with KOOLGAS defrost, suction, and liquid lines should not contact each other and should be insulated for a minimum of 30’ from the refrigerator. Additional insulation for the balance of liquid and suction lines is recommended and required wherever condensation and dripping would be objectionable.

Control Settings - Self Contained
On Self Contained cases all functions, defrost, fans, temperature are controlled by Pagon
Access to TX Valves and Drain Lines
Mechanical - Remove product from end of case. Remove product racks. Remove refrigeration and drain access panels (labeled). TX valve (mechanical only) and drain are located under each access panel at end of the case.
Electronic - The Electronic Expansion valve master and slave cylinder(s) are located within the electrical access panel(s).
Electronic Expansion Valve (Optional)
A wide variety of electronic expansion valves and case controllers can be utilized. Please refer to EEV and controller manufacturers information sheet. Sensors for electronic 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.
