Operation Section 4. REFRIGERANT SYSTEM 4.1 Refrigerant System Construction The component parts of the refrigerant system include the following: • Compressor, Evaporator, Condenser, Accumulator, Capillary tube The parts above are all connected by copper piping with brazed connections. The circled portion in the figure below shows the part connections.
Operation Section 4.2 Compressor • The compressor used for the unit is hermetically sealed. The compressor and the compressor motor are in one casing. (1) Compressor construction • The construction of a rotary type compressor is divided into two mechanisms; the drive mechanism (compressor motor), and the compression mechanism (compressor).
Page 16
Operation Section (2) Basic compressor operation • The roller (compression mechanism) is set Discharge eccentrically with a certain distance given from Hole Spring Discharge the axis of the center of the cylinder. A spring Suction Valve Hole loaded blade is mounted on the cylinder. The Blade roller turns to compress the refrigerant in the space between the cylinder and eccentrically...

Discharge Blade Valve 2) Since pressure in the discharge chamber is higher than in the cylinder, the discharge valve is kept closed. Roller I001676 2) Suction and compression 1) The pressure in the cylinder increases...
Operation Section (4) Compressor lubrication • The lubrication system is comprised of a hollow shaft, an oil scraper mounted at the end face, hollow shaft, a shaft journal (shaft Rotor bearing), and the lubrication groove for the shaft journal. The lubrication groove is wider Hollow Shaft than the oil hole.
Operation Section 4.4 Capillary Tube • The capillary tube is a long thin tube that High Temp./High Press. utilizes line flow resistance as an expansion Liquid Refrigerant valve. The length and the inner diameter of the capillary tube are determined according to the capacity of the refrigeration system, operating conditions, and the amount of refrigerant.
Operation Section 5.3 Basic Operation (1) Control panel • Before operating the unit, it is important to be familiar with the basic operation of the control panel. Activates/deactivates the cool mode; turns the unit off. COOL ON/OFF Button FAN Button Activates/deactivates the fan only mode;...
Page 24
Operation Section (2) Fan only mode • When the FAN button on the control panel is pressed, the FAN “ON” LED illuminates, and the fan operates. At this time, the compressor is off, and only the fan is in operation. When the FAN button is pressed again, the fan stops.
Operation Section 5.4 Relay Board • The relay board contains the compressor and fan on relays, in addition to a step-down transformer that converts the line voltage (Classic10: 115 VAC, Classic18: 208/230 VAC) to 12 V. This voltage is then converted from AC to DC and used for relay coil activation. The 12 V (DC) power is sent to the control panel assembly, further being reduced to 5 V for the system logic.

Page 28
Operation Section (4) Compressor time delay control (compressor protection) • Compressor protection consists of a time delay program within the microprocessor. This program prevents a heavy load from being applied to the compressor motor when restarting the unit (cool mode) after a very short period of time. This “delay” is in effect any time the compressor is turned on by either the COOL ON/OFF button, or power interruption restart (automatic recovery.) - Time Delay Program Specifications: 120 sec.
Page 29
Operation Section (6) Temperature control • During cool mode, temperature control changes the 52CM (compressor on/off) relay status according to RTS temperature in the available range (-4 to 140 °F (-20 to 60 °C)). 52CM (Compressor Relay) (Set Temp. -3 °F) Set Temp (Set Temp.
Operation Section 5.6 Self-Diagnostic Codes • Self-diagnostic codes are displayed on the control board under the following conditions. Output Buzzer Indication Condition Signal (On Board) When the drain tank switch is activated, the LED displays “FL” and the unit turns off automatically.

Specifications: Classic10 - Rated Voltage: 115 V - Rated Output: 600 W Specifications: Classic18 - Rated Voltage: 208/230 V I001690 - Rated Output: 1100 W (2) Compressor overload relay...
Operation Section 5.8 Fan Motor • The fan motor is a single phase, induction type. The motor rotates the fan on both the evaporator side and the condenser side at the same time. • The following table shows the specifications of the fan motor used for each model.
Operation Section 5.10 Auxiliary Relay (For Classic18 Only) • The auxiliary relay is normally closed when the unit is in operation (fan or cool), and supplies power to the fan motor. • When current flows across A1 and A2, terminals 13 and 14, 23 and 24, 33 and 34, 43/41 and 44/42 conduct.
Operation Section 5.12 Drain Tank Switch • The drain switch activates and stop the operation of compressor motor and fan motor when approximately 4.4 gal (16 L) of drain water accumulates in the drain tank. At the same time, control panel display "FL", and compressor and fan operations stop. This system uses a 250 V, 0.1 A rating micro switch for this function.
• All electrical work should only be performed by qualified electrical personnel. Repair to electrical components by non-certified technicians may result in personal injury and/or damage to the unit. All electrical components replaced must be genuine MovinCool parts, purchased from an authorized reseller.
