Page 8: Pre-Installation
PRE-INSTALLATION INSTRUCTIONS I. General Information ® Please read this manual prior to installing your Master-Bilt equipment. This information is based on good refrigeration practice and should be used as a guide for installation and operation. To complete the installation, please records the data requested on the Installation Data form on page 35 of the manual and return this manual to the owner. -
Page 9: Handling And Placement Of Evaporator Coil In Walk-In
II. Handling and Placement of Evaporator Coil in Walk-In To minimize damage to the evaporator coil, it is recommended that the carton (or crate) not be removed until the evaporator coil is moved close to its final location. When the container is removed from the evaporator coil, extreme care must be used when lifting and mounting to the ceiling, to prevent sheet metal damage. - Page 10 EVAPORATOR DRAIN LINE INSTALLATION: a. Copper lines must be used for drains. Plastics are not acceptable. b. Drain lines must exit the freezer or cooler as quickly as possible and must have a pitch of at least 1/8” inch/foot downward or meet the local code requirements. c.

Page 11: Electrical
III. Electrical Electric power supply must match the condensing unit power requirements indicated on the unit data plate. A WIRING DIAGRAM IS LOCATED ON THE INSIDE OF THE ELECTRICAL BOX COVER. All field wiring may enter the holes provided in left side, back and bottom of the electrical box. -
Page 12: Leak Check
NOTICE Be sure solenoid valves are open before beginning evacuation and leak check. v. Leak Check When all refrigeration line connections have been made, the complete system, including factory connections, should be leak checked. Add the proper refrigerant to 60 psig, then boost to 175 psig with dry nitrogen. Leak checks all joints with an electronic leak detector or a halide torch. -
Page 13: Finish Charging Procedures
FINISH CHARGING PROCEDURES A. Preliminary Be sure all service valves are “open”. Loose the compressor hold-down bolts and remove shipping clips to allow compressor to float freely on the springs. Check evaporator fan motors after start-up. Medium temperature, air defrosts fans run continuously. Low temperature fans and coolers provided with electric defrost will be delayed by the fan control. -
Page 14: Pre-Charged Remote Refrigeration Systems
Technical installation instructions for Pre-Charged Remote Refrigeration are given on the following pages. Installation requirements for other remote refrigeration systems may vary. If additional information is needed, your certified refrigeration mechanic or electrician can call Master-Bilt at 800-684-8988. Quick-Couples are pre-charged with the proper refrigerant at the factory. D. - Page 15 Connect correctly rated over current protection device in the service line to the service line J- ● box on the condensing unit. After routing condensate line from drain pan of evaporator coil, seal around all refrigeration, ● electrical and drain lines with silicone or butyl caulking. ●...

Page 16: Final Check List For All Models
VII. Final Check List for All Models A. Check high-low pressure control settings. B. Check setting of defrost timer: Medium temperature 2 to 4 defrosts/24 hours, with 35 minutes fail safe. Low temperature 3 to 4 defrosts/24 hours, with 44 minutes fail safe. C. -

Refrigerant lines should be supported and fastened properly to prevent leaks and for professional looking installation. -
Page 20: Low Ambient Operation Charge
LOW AMBIENT OPERATION CHARGE ® Some Master-Bilt units are provided with condenser flooding valves to maintain proper head pressure during the winter. These valves function by reducing the effective condenser area by flooding or “backing up” refrigerant in the condenser to reduce the amount of surface available for condensing. - Page 21 5/16 Rev.
