Consult a qualified installer, service agency, or your distributor or branch for information or assistance. The qualified installer or agency must use factory -- authorized kits or accessories when modifying this product. Refer to the individual instructions packaged with the kits or accessories when installing. Follow all safety codes. Wear safety glasses, protective clothing, and work gloves. Use quenching cloth for brazing operations. Have fire extinguisher available. Read these instructions thoroughly and follow all warnings or cautions included in literature and attached to the unit. Consult local building codes and National Electrical Code (NEC) for special requirements. Recognize safety information. This is the safety--alert symbol !! When you see this symbol on the unit and in instructions or manuals, be alert to the potential for personal injury. Understand these signal words: DANGER, WARNING, and CAUTION. These words are used with the safety-- alert symbol. DANGER identifies the most serious hazards whichwillresult in severe personal injury or death. WARNING signifies hazards whichcouldresult in personal injury or death. CAUTION is used to identify unsafe practices whichmayresult in minor personal injury or product and property damage. NOTE is used to highlight suggestions whichwillresult in enhanced installation, reliability, or operation. !WARNING ELECTRICAL SHOCK HAZARD Failure to follow this warning could result in personal injury or death. Before installing, modifying, or servicing system, main electrical disconnect switch must be in the OFF position. There may be more than 1 disconnect switch. Lock out and tag switch with a suitable warning label. INTRODUCTION Section 1 of this Service Manual provides the necessary information to service, repair, and maintain the EEZ family of Puron air conditioners and heat pumps. Section 2 of this manual is an appendix with data required to perform troubleshooting. Use the Table of Contents to locate a desired topic.

Fig. 1 – Condensate Pump
On high wall fan coils, the condensate pump has a lift capability of
18 ft (5.5 m) or the discharge side with the pump mounted in the
fan coil or 6 ft (1.8 m) on the suction side if the pump must be
remote mounted. The pump mounts inside the unit with quick
plug--in connections, and is recommended when adequate drain
line pitch cannot be provided, or when the condensate must move
up to exit.
NOTE: An external 115v power source will be required to run the
pump on unit sizes 9k and 12k.
OUTDOOR UNITS
LOW AMBIENT KIT
The kit controls condenser fan cycling using a pressure switch. It is
specifically designed to control fan--motor cycles in response to
saturated condensing pressure. This device maintains a constant
saturated condensing temperature of 100_F±10_F (37.78_C±
--12.22_C) at outdoor--air temperatures between 55_F and --20_F
(12.78_C±--12.22_C), and can be used on all outdoor units
without changing the outdoor fan motor.
CRANKCASE HEATER
Available for units with rotary compressors. Heater clamps around
compressor oil sump. Recommended for low--ambient applications
on sizes 9, 12 , 18, 24 and long line applications.

9 WIRING The main power is supplied to the outdoor unit. The field supplied connecting cable from the outdoor unit to indoor unit consists of four wires and provides the power for the indoor unit as well as the communication signal between the outdoor unit and indoor unit. Voltage drop on the connecting cable should be kept to a minimum. Use cable size and max length below: 18 AWG50 ft. (16 m) 16 AWG100 ft. (33 m) CONNECTION DIAGRAMS CONNECTING CABLE CONNECTING CABLECONNECTING CABLE CONTROL CONTROL Notes: 1. Do not use thermostat wire for any connection between indoor and outdoor units. 2. All connections between indoor and outdoor units must be as shown. The connections are sensitive to polarity. 3. On the 18k and 24k units, the “S” terminal “CONTROL” output is pulse DC with a potential AC voltage shock hazard. A07654 Fig. 5 – Connection Diagrams 38/40MVC, MVQ
