ENGINEERING GUIDE TO SPECIFICATION

FOR REMOTE REFRIGERATION PACKAGE

MINI-PAK REFRIGERATION SYSTEM

THE REFRIGERATION PACKAGE SHALL BE A PRE-ENGINEERED AND FACTORY ASSEMBLED UNIT, TRADE NAME "MINI-PAK", AS MANUFACTURED BY COLDZONE, A DIVISION OF HEAT TRANSFER PRODUCTS GROUP, 1810 VINEYARD AVE. ONTARIO, CA 91761.

PHONE: (800) 772-2653, FAX: (714) 529-8503.

CONTRACTOR SHALL FURNISH AND INSTALL, WHERE SHOWN ON PLANS, (1) COLDZONE U.L. APPROVED "MINI-PAK".

1. MINI-PAK REFRIGERATION SYSTEM

THE ENTIRE UNIT IS TO BE WEATHER-PROOFED AND MINIMUM OF TWO COATS OF PAINT SHALL BE APPLIED TO MAKE THE UNIT RUST-PROOF. THE UNIT SHALL BE PROVIDED WITH MULTI-CIRCUITED AIR-COOLED CONDENSER FOR COOLER, FREEZER AND ICE MACHINES. SUCTION LINE FOR LOW TEMPERATURE UNIT MUST BE INSULATED WITH ARMAFLEX.

2. REFRIGERATION UNITS

A. CRANKCASE HEATER SHALL BE PROVIDED WITH EVERY COMPRESSOR.

B. AIR-COOLED CONDENSING UNITS SHALL BE SEMI-HERMETIC, HERMETIC OR GLACIER SCROLL TYPE (COPELAND). EACH UNIT

SHALL BE EQUIPPED WITH HIGH-LOW PRESSURE CONTROL, LIQUID LINE DRIER, SIGHT GLASS, SUCTION AND DISCHARGE

VIBRATION ELIMINATOR, AND HEAD PRESSURE CONTROL.

C. ALL COMPRESSOR UNITS SHALL BE NEW AND FACTORY ASSEMBLED TO OPERATE WITH THE REFRIGERANT SPECIFIED IN

THE ENGINEERING SUMMARY SHEET.

3. PRE-PIPING

A. ALL COPPER TUBING TO BE REFRIGERANT GRADE A.C.R. OR TYPE "L".

B. ALL TUBING SHALL BE SECURELY SUPPORTED AND ANCHORED WITH CLAMPS.

C. ALL REFRIGERANT LINES SHALL BE EXTENDED TO ONE SIDE OF THE PACKAGE IN A NEAT AND ORDERLY MANNER.

D. SILVER SOLDER AND/OR SIL-FOS SHALL BE USED FOR ALL REFRIGERANT PIPING. SOFT SOLDER IS NOT ACCEPTABLE.

E. ALL PIPING TO BE PRESSURE TESTED WITH NITROGEN AT 300 PSI. AFTER THE CONDENSING UNIT AND COIL HAVE BEEN

CONNECTED, THE BALANCE OF THE SYSTEM SHALL BE LEAK TESTED WITH ALL VALVES OPEN.

4. CONTROL PANEL

A. THE PACKAGE SHALL HAVE FACTORY MOUNTED AND PRE-WIRED CONTROL PANEL COMPLETE WITH INTERLOCKED MAIN

FUSED DISCONNECT, COMPRESSOR CIRCUIT BREAKERS, CONTACTORS AND TIME CLOCKS WIRED FOR SINGLE POINT

POWER CONNECTION.

B. ELECTRICAL CONTRACTOR SHALL PROVIDE AND INSTALL MAIN POWER LINES TO PANEL, AND USE WIRE HARNESS WIRING FOR CONTROL AND DEFROST HEATER BETWEEN THE DEFROST CLOCK AND THE REFRIGERATION FIXTURES, ALL IN

ACCORDANCE WITH THE WIRING DIAGRAM AND LOCAL CODES.

GENERAL NOTES

1. GENERAL CONTRACTOR

A. CONTRACTORS SHALL VERIFY ALL DIMENSIONS AND COORDINATE WITH OTHER TRADES.

B. GENERAL CONTRACTOR SHALL PREPARE AND WEATHERPROOFING THE PLATFORM AND CURBED OPENINGS.

2. REFRIGERATION CONTRACTOR

A. THE COMPLETE SYSTEM SHALL BE EVACUATED WITH VACUUM PUMP.

B. ALL COPPER TUBING TO BE REFRIGERANT GRADE A.C.R. OR TYPE "L".

C. CHARGE, TEST, AND ADJUST EACH UNIT TO BE IN AN OPERATIONAL SYSTEM.

D. SILVER SOLDER AND/OR SIL-FOS SHALL BE USED FOR ALL REFRIGERANT PIPING. SOFT SOLDER IS NOT E. ALL PIPING TO BE PRESSURE TESTED WITH NITROGEN AT 300 PSI. AFTER THE CONDENSING UNIT AND COIL HAVE BEEN

CONNECTED, THE BALANCE OF THE SYSTEM SHALL BE LEAK TESTED WITH ALL VALVES OPEN.

F. REFRIGERATION CONTRACTOR TO PROVIDE AND INSTALL DRAIN LINE HEATER IN FREEZER TO BE CONNECTED BY

ELECTRICAL CONTRACTOR

3. ELECTRICAL CONTRACTOR

A. ELECTRICAL CONTRACTOR TO PROVIDE POWER FROM REFRIGERATION PACKAGE AND CONNECT CONTROL AND

DEFROST SYSTEM AS CALLED FOR IN THE WIRING DIAGRAM.

B. ALL ELECTRICAL WIRING AND INSTALLATION SHALL BE IN ACCORDANCE WITH THE WIRING DIAGRAM AND LOCAL CODES.

4. PLUMBING CONTRACTOR

A. PLUMBING CONTRACTOR TO PROVIDE HARD A.C.R. OR TYPE "L" COPPER DRAIN LINES FOR WALK-IN REFRIGERATOR AND

FREEZER, PITCHED 1/4" PER FOOT OF RUN. IN FREEZER, UNHEATED DRAIN LINE MUST BE OUTSIDE OF FREEZER WALL TO PREVENT FREEZING. TRAP DRAIN LINE OUTSIDE OF REFRIGERATED SPACE TO AVOID ENTRANCE OF WARM AND MOIST
