Performance Characteristic Charts
Actual performance can be determined by conducting correction after looking up the following charts.
Based on the ambient temperature and desired return water temperature, we can locate the corresponding
performance factor in these charts, then the corresponding actual cooling (heating) capacity and power input
can be determined by using the following formula.
Actual cooling (heating) capacity = nominal cooling (heating) capacity * cooling (heating) performance
correction factor
Actual power input = nominal power input * power input correction factor.

Page 38
Mounting
When mounting, please use foundation bolts or expansion bolts to fasten the unit with foundation supporter.
It is advisable to pad the unit bottom against foundation by using vibration absorption rubber to prevent
noise and vibration.
Chilled Water Piping
Chilled water piping must be insulated and waterproof to avoid performance loss and moisture condensing
on it.
To guarantee the chilled water quality, the water strainer shipped with unit must be installed on the chilled
water in pipe.
Both chilled water inlet and outlet port are external taper thread connections.
When performing water pipe connection, use gripping pliers to fix the unit connections to avoid the reserved
connections on unit being directly suffered from revolving torque when fastening.
Air vent valve should be installed at highest points on chilled water piping system, see detailed information in
“chilled water system installation schematic diagram”. After completing chilled water piping, carry out leak
detection and 0.4MPa pressure test to ensure having no fault, then fully fill water in system, open air vent
valve, purge all the air trapped in the piping system, after that shut off the air vent valve. Water drainage
valve should be installed at lowest points on chilled water piping system.
In order to achieve the unit long-life operation, it is recommended to give first priority to new type plastic
water pipe such as PP-R, PVC, never use galvanized steel pipe when choosing the material of water pipe.
Caution:
• The accessory strainer shipped with unit must be installed on water in pipe, otherwise failure of the unit
may be caused.

• Never put the chiller into the condition of being operated with very oily, salty or acidic water, because
these substances may lead to capacity drop and unit damage. Be sure to use clean water when filling in
the water circuit to avoid heavy corrosion and choking of the system.
• Don’t use the water pump equipped in unit to clean piping. If using the pump to clean is required, you
can fill clean water in system at water in side, meanwhile make the pump running, please conduct 30minute pump operation, then clean the strainer.

Condensate Drainage Connection (For MAC030CR to MAC070CR Only)
Condensate may be produced when unit being operated under heating cycle. In order to properly
remove it, please follow these steps below:
Please open either hole, located on left or right panel, to suit your need by knocking off the easily –
removed cover with a hard stool, make the 1” sized condensate pipe extend out.
Connect the condensate pipe to drain ditch.
Cooling only unit has no need to do this work.
Power Connection
Laws and regulations concerning electrical wiring work vary by country. Therefore, work should basically be
performed according to the regulations of each country.
Before power connection, make sure that your local power supplies type accords with the unit nameplate.
Knock out t he hol e
usi ng f or condensat e

Servicing and Maintenance
Servicing
• Service and maintenance are to be performed only by qualified personnel who are well trained with
refrigeration engineering. Before restart the unit, do a thorough check and analysis of the unit safety
control components.
• The optimum design of the refrigerating system eliminates the possibility of problems being occurred
during normal operation. There is no need to conduct any maintenance to refrigerant piping if the unit is
under normal running.
• McQuay designers have given full consideration to make servicing convenient during unit development.
After opening service panel, both servicing and maintenance can be easily carried out.
• Under normal environment, the only work needed is checking the return air way and cleaning the heat
exchange surface regularly at month or season interval decided on operating condition.
• If the surrounding is very dirty or oily, for maintaining superior performance and sufficient capacity,
please ask specialized personnel to do regular cleaning of heat exchanger.
Maintenance
• For keeping consistent performance and durability with safe, effective and long-life operation,
always conduct proper and regular maintenance to the unit.
• For long period of operation time, the heat exchanger will become dirty impairing its effectiveness
and reducing the performance of the air conditioner. Consult your local dealer on the cleaning of the
heat exchanger.
• No main maintenance or servicing needed for the internal water circuit except the water pump
failure. It is advised that regular check on the strainer should be conducted and replace the water
strainer if the strainer is dirty or clogged.
• Always check the water level in the system, for the target of protecting the moving components in the
hydraulic kit from overheating, excessive wearing and water freeze.
• All the chilled water in the hydraulic system must be drained out completely during unit shutdown in
winter, to avoid water piping damage due to freeze.
