Company BusinessZamil Air Conditioners was founded in 1974 as one of the first air conditioning companies to be established in Saudi Arabiaand today is a leading international manufacturer of air conditioning systems and is Number One in the Middle East.

Zamil Air conditioners manufactures both consumer and central air conditioners and has sales operations in over 55countries in the Middle East, Europe, Africa and Asia.

The company’s operations are structured into four Strategic Business Units (SBUs) supporting five in-house product andservice brands as well as a number of international brands under the OEM sales.

The five in-house brands are Classic, Cooline, CoolCare, Clima Tech and Geoclima.

The four SBUs are:1. Consumer Business Unit supporting Classic, Cooline, GE and OEM brands for consumers.2. Unitary & Applied Business Unit supporting Zamil, Cooline, GE and OEM brands for commercial and industrial customers.3. Zamil CoolCare Business Unit providing industrial, electro mechanical contracting services, HVAC maintenance,

retrofit & operation services and parts.4. Geoclima srl is an independent business supporting other SBUs for their requirements of chillers & double skin AHU’s.

The first three SBUs - Consumer Products, Unitary & Applied Products and CoolCare direct their business operationsfrom the corporate headquarters in Dammam, Saudi Arabia.

Geoclima has its engineering & production operations located at Monfalcone, Italy and has a design center in Austria.

All the four SBUs, while operating independently, supplement each other’s activities in a way that makes synergy work atits best and achieve the corporate goals of maximizing customer satisfaction.

Factories and ProductionsZamil Air Conditioners has two manufacturing plants in Dammam, Saudi Arabia and has one specialty production facilityin Italy operated by Geoclima.

The company can produce up to 550,000 Room Air Conditioners, 300,000 Mini-Split systems and 50,000 Central AirConditioning systems per year.

Quality & Product CertificatesThe Quality systems and policies at Zamil Air Conditioners comply with the required ISO 9001:2008 certification.

Zamil Air Conditioners is the first company in Saudi Arabia to receive the SASO (Saudi Arabia’s Standard Organization)Certificate for Room Air Conditioners. ZAC’s products are also certified with:1. CE (Council of European Community)

2. UL (Underwriters Laboratory)

3. Eurovent (Certified Performance)

4. ETL (Test Facilities)

5. SASO (Saudi Arabian Standards Organization)

6. ISO 9001:2008 (International Organization for Standardization)

7. ASME (American Quality of Mechanical Engineers)

Other awards include the prestigious Engineering Excellence Award of General Electric and the inaugural Prince Mohammedbin Fahd Al Saud Award for Factory Safety.

Our ProductsIn addition to the consumer products such as the Room Air Conditioners (RAC) and the Mini Splits, Zamil Air Condition-ers manufacturers a host of residential, commercial and industrial air conditioners. This broad range extends from theConcealed Units up to 5 TR, the Ducted Splits up to 30 TR, the Packaged Units up to 95 TR, the Single and Double SkinAir Handling Units up to 138,316 CFM and the Water Chillers up to 500 TR cooling capacity.

WIDE RANGE OF HEATER SIZES

QUIET, PULSE FREE AIR DELIVERYCentrifugal fans that are statically and dynamically balanced, handle up to 0.5" w.g. external static pressure allowing youto keep the unit away from your comfort zone.

STANDARD SPECIFICATIONSUNIT CONSTRUCTIONThese units are fabricated of heavy gauge galvanized steel to ensure lasting durability and dependable performance withminimum maintenance. The panels are insulated to provide positive protection against sweating and maximum dampingof air noise.

This unit is designed for those concealed overhead installations which require supply ductwork. A 1" duct collar isprovided into the front panel for supply air duct connection. The standard arrangement provides return air from the rearside. This arrangement may be reversed to provide bottom return air by simply interchanging the bottom and rear panel.This reversal can be easily accomplished in the field.

Access to the blower motor assembly is provided through the removable bottom panel from where the complete fan/motor can be removed for servicing.

FANSThe centrifugal, forward curved, double width fan wheels are statically and dynamically balanced for quiet and smoothperformance. Blower housing is rugged galvanized steel to provide added rigidity and assure quiet & smooth operation.

MOTORSMotors are permanent split capacitor type with three speed windings and built-in thermal overload protection. The bear-ings are of sleeve type.

FILTERSAll models are furnished with 1/2" thick permanent washable type aluminum filters as standard.

COILSCoils are 3/8" OD copper tubing, constructed of enhanced copper tubes and mechanically bonded to aluminum fins. Asan option, corrugated copper fins or coated aluminum fins may be provided. Manual air vents are provided on allchilled water coils. The standard chilled water coil is 3 rows for all models & 4 row chilled water coil is also provided as anoption. A 4 pipe coil consisting of 3 rows of cooling coil and 1 row of heating coil is used for heating application. Each coilis pressure tested in the factory at not less than 300 psi (2070 kpa) air pressure. Coils conform to ARI 410.

DRAIN PANThe condensate drain pan is fabricated of 18 gauge galvanized steel. The drain pan is powder coat painted. The outersurface is thermally insulated.

DRIP LIPThe purpose of a 'drip-lip' is to capture any condensate from the valve packages and direct it to the drain pan. It isfabricated of a single metal formed to fit on the side of the drain pan. They may be installed in the field and should alwaysbe pitched towards the drain pan to assure proper drainage. This will be supplied loose for field installations along withvalve packages.

OPTIONSELECTRIC HEATERSThe heater element is of the resistance open coil type. Thermal overheat cut-outs and fusible links are provided to shut-off power to heaters in case of airflow failure.

VALVE PACKAGESValve packages are available as an option (3D for two pipe system and 4D for four pipe systems). These valves can befactory installed or supplied loose for field installation.

THERMOSTATAn attractive wall mount three speed electronic thermostat with all required functions and features for safe and smoothoperation which can be used for cooling & heating requirements. This thermostat can be supplied loose through separateKit number.

INSTALLATIONThe complete shipment should be inspected for damage. Any damage, visible or concealed, should be reported immedi-ately to the delivery man or driver and noted on the shipping invoice.

Place unit in position and make sure that unit is level. This is important to assure proper drainage and operation. Slotsprovided in the mounting brackets should be used for installing the units.

ELECTRICALPlease ensure power supply (V-Ph-Hz) to the unit is as per unit nameplate requirements.

Caution: Operation of the unit on improper power supply will result in damage to the unit.

Warning: Before installation or servicing, always TURN OFF all power to the unit. There may be more than one discon-nect switch. Ensure all of them are turned off.

GROUND & POWER WIRESConnect power wires as per wiring diagram. Connect ground wire to the ground lug inside the control box.

MAINTENANCECOILCoil may be cleaned by removing and brushing between fins with a stiff wire brush. Brushing should be followed by cleaningwith vacuum cleaner. The coil may also be cleaned by using a high pressure air, if compressed air source is available. Itshould be pointed out that if air filters are used and periodically cleaned, the coils will not be clogged up prematurely.

DRAIN PIPEDrain pipe should be checked before summer operation of unit. If it is clogged, steps should be taken to clear the debrisso that condensate will flow out easily. A standard pipe cleaner for 1/2" ID pipe may be used. Periodic checks of the drainpipe should be taken during summer operation, as there is a possibility of it becoming clogged with dirt.
