Installation of Outdoor Unit

Condensed Water Disposal of Outdoor Unit (Heat Pump Unit Only)

There are 2 holes on the base of outdoor unit for condensed water to ﬂ ow out. Insert the drain elbow to one of the holes. To install the drain elbow, ﬁ rst insert one portion of the hook to the base (portion A), the pull the drain elbow in the direction shown by the arrow while inserting the other portion to the base. After installation, check to ensure that the drain elbow clings to base ﬁ rmly. If the unit is installed in a snowy and chilly area, condensed water may freeze in the base. In such case, please remove plug at the bottom of unit to smooth the drainage.

•

Application Information MWM-J-2009

As condensing temperature rises, evaporating temperature rises and cooling capacity drops. In order to achieve maximum cooling capacity, the location selected for outdoor unit should fulﬁ ll the following requirements:

Install the condensing (outdoor) unit in a way such that hot air distributed by the outdoor condensing unit cannot be drawn in again (as in the case of short circuit of hot discharge air). Allow sufﬁ cient space for maintenance around the unit.

Ensure that there is no obstruction of air ﬂ ow into or out of the unit. Remove obstacles which block air intake or discharge. The location must be well ventilated, so that the unit can draw in and distribute plenty of air thus lowering the condensing temperature.

A place capable of bearing the weight of the outdoor unit and isolating noise and vibration. A place protected from direct sunlight. Otherwise use an awning for protection, if necessary.

The location must not be susceptible to dust or oil mist.

Installation Clearance

Outdoor units must be installed such that there is no short circuit of the hot discharge air or obstruction to smooth air ﬂ ow. Select the coolest possible place where intake air should not be hotter than the outside temperature (max. 45˚C).

ALL MODELS A B C D

Minimum Distance 300 mm 1000 mm 300 mm 500 mm

CAUTION : If the condensing unit is operated in an atmosphere containing oils (including machine oils), salt (coastal area), sulphide gas (near hot spring, oil reﬁ nery plant), such substances may lead to failure of the unit.

MWM-J-2009 Application Information

Wiring

Electrical Connections

Wiring regulations on wire diameters differ from country to country. Please refer to your LOCAL ELECTRICAL CODES for ﬁ eld wiring rules. Be sure that installations comply with the rules and regulations.

General Precautions

Ensure that the rated voltage of the unit corresponds to the name plate before carrying out proper wiring according to the wiring diagram. Provide a power outlet to be used exclusively for each unit. A power supply disconnects and a circuit breaker for over-current protection should be provided in the exclusive line. The unit must be GROUNDED to prevent possible hazards due to insulation failures. All wiring must be ﬁ rmly connected. All wiring must not touch the hot refrigerant piping, compressor or any moving parts of fan motors.

Refrigerant Piping

Piping Length and Elevation

When the pipe length becomes too long, both the capacity and reliability drop. As the number of bends increases, system piping resistance to the refrigerant ﬂ ow increases, thus lowering the cooling capacity, and as the result the compressor may become defective. Always choose the shortest path and follow the recommendation as tabulated below:

MWM-J-2009 Application Information

Special Precautions When Dealing With Refrigerant R410A Unit

(1) What is new refrigerant R410A? R410A is a new HFC refrigerant which does not damage the ozone layer. The working pressure of this

new refrigerant is 1.6 times higher than conventional refrigerant (R22), thus proper installation / servicing is essential.

(2) Components Mixture weight composition R32(50%) and R125(50%)

(3) Characteristic

R410A liquid and vapor components have different compositions when the ﬂ uid evaporates or condenses. Hence, when leak occurs and only vapor leaks out, the composition of the refrigerant mixture left in the system will change and subsequently affect the system performance. DO NOT add new refrigerant to leaked system. It is recommended that the system should be evacuated thoroughly before recharging with R410A. When refrigerant R410A is used, the composition will differ depending on whether it is in gaseous or liquid phase. Hence when charging R410A, ensure that only liquid is being withdrawn from the cylinder or can. This is to make certain that only original composition of R410A is being charged into the system. POE oil is used as lubricant for R410A compressor, which is different from the mineral oil used for R22 compressor. Extra precaution must be taken not to expose the R410A system too long to moist air.

(4) Check list before installation / servicing

Tubing Refrigerant R410A is more easily affected by dust of moisture compared with R22, make sure to temporarily cover the ends of the tubing prior to installation. Compressor oil No additional charge of compressor oil is permitted. Refrigerant No other refrigerant other that R410A Tools (size of service port is different from R22 system) Tools speciﬁ cally for R410A only (must not be used for R22 or other refrigerant)

i) Gauge manifold and charging hose ii) Gas leak detector iii) Refrigerant cylinder/charging cylinder iv) Vacuum pump c/w adapter v) Flare tools vi) Refrigerant recovery machine

(5) Handling and installation guidelines Like R22 system, the handling and installation of R410A system are closely similar. All precautionary

measures; such as ensuring no moisture, no dirt or chips in the system, clean brazing using nitrogen, and thorough leak check and vacuuming are equally important requirements. However, due to its hydroscopic POE oil, additional precautions must be taken to ensure optimum and trouble free system operation.

(a) During installation or servicing, avoid prolong exposure of the internal part of the refrigerant system to

moist air. Residual POE oil in the piping and components can absorb moisture from the air.

(b) Ensure that the compressor is not exposed to open air for more than the recommended time speciﬁ ed

by its manufacturer (typically less than 10 minutes). Removed the seal plugs only when the compressor is about to be brazed.

more stringent than R22 system so as to ensure no incompressible gas and moisture in the system.

Application Information MWM-J-2009

(d) When charging R410A, ensure that only liquid is being withdrawn from the cylinder or can. This is

to ensure that only the original composition of R410A is being delivered into the system. The liquid composition can be different from the vapor composition.

ip-pipe

Liquid withdrawal

Invert cylinder without dip-pipe

(e) Normally, the R410A cylinder or can is being equipped with a dip pipe for liquid withdrawal. However,

if the dip pipe is not available, invert the cylinder or can so as to withdraw liquid from the valve at the bottom.

Performance Data MWM-J-2009

Performance Data

Interpolation and Extrapolation method can be used to get the total capacity, TC and sensible capacity, SC at those temperatures which are not stated out in the table.

Example:

Model: MWM009J - MLC009C Indoor Condition: 23°C DB, 15°C WB Outdoor Condition: 37°C DB

Solution:

Overall

Based on the Performance Table

1. Refer to the Indoor DB column,

23°C is located between 20°C and 24°C (Thus, Interpolation need to be applied)

2. Refer to the Indoor WB column,

15°C only available in the case of Indoor DB = 20°C. (Thus, Extrapolation between 16°C WB and 17°C WB during 24°C indoor DB is required)

3. Refer to the Outdoor DB column,

37°C is located between 35°C and 40°C. (Thus, Interpolation need to be applied)

Please follow the steps below in order to get the required capacity.

1st Step Extrapolation of Indoor WB

Find TC, SC for (a)

Indoor: 24°C DB, 15°C WB

Outdoor: 35°C DB

(b) Indoor: 24°C DB, 15°C WB

Outdoor: 40°C DB
