INSTALLATION INSTRUCTIONS

GENERAL

These units are shipped completely assembled, charged, and wired. They do not require any field installation of refrigerant tubing. Units require external power, thermostat wiring, condensate drain piping and ducting as applicable.

Size of unit for an installation should be based on a heat gain calculation made according to applicable standards. Units must also be installed in accordance with regulations of the "National Fire Protection Association" and local electrical codes. Where local regulations conflicts with the instructions in this manual, installer should adhere to local standards.

Prepare your concrete pad or steel stand based on the corresponding dimensions. Remove shipping protective covers and wooden crating and lift unit from base and place in position with suitable rubber vibration isolators.

All field installed accessories are to be installed by the customer with necessary reinforcements as required.

LOCATION OF UNIT

When selecting the location for the unit, the following points should be kept in mind:

1. Provisions for a concrete pad or steel stand base.

2. That the terrain allows for drainage away from the unit.

3. If the unit is to be roof mounted, inspect the roof for load bearing capacity. The roof should have sufficient structural strength to carry the weight of the unit.

4. Install unit on vibration isolation pads, i.e. on rubber mounting pads.

5. Availability of electric power.

6. To position the unit for unrestricted air circulation of the condenser air inlet and to prevent any possibility of air recirculation from the condenser fan discharge air (see figure on next page).

7. Check minimum clearances required for your unit, with regard to walls, or other obstructions (see figure on next page).

8. Air cooled equipment should not be installed under low structural overhangs which can cause condenser air recirculation or restriction. Observe minimum of clearance (see figure on next page).

9. Care should be taken to prevent air from other sources from entering condenser, if this air is at a high temperature.

10. Level the unit on its final location and be sure that the levelling tolerance is ±5 mm per linear meter in any direction.

CAUTION: Do not install the unit as indoor unit, install it in an open area, and unit air inlets must not be located near exhaust vents or other source of contaminated air.

- COMPLETE UNIT CONTROL: Provides complete unit control for heating and cooling application whether single

stage or two stage utilizing the input from sensor that measure temperatures during unit operation.

- COMPRESSOR LOCKOUT: If any of the unit’s safety controls trip due to abnormal conditions the Electronic

Control locks out the compressor, preventing restart, unless attended by qualified service technicians. The unit can be re-started only by reset the thermostat after ensuring safe system conditions.

- LEAD LAG OPERATION: The unit electronic controls automatically alternate lead and lag the compressors for

even operation. Compressor #1 can be set always lead as an option.

- ANTI-RECYCLE TIMER: For compressor safety in case of accidental manual reset or immediate recycling of

thermostat due to load demand. This considerably improves compressor life.

- PUMP DOWN OPTION: In units equipped with pump down system the time delay creates the required time gap between

the solenoid opening and compressor start to equalize the pressure in the system prior to compressor start up.

- AUTO/MANUAL RESET OF THE ALARM SIGNALS.

- FULL CONTROL OF THE INDOOR FAN: Fan operation can be selected either to run continuously or stage with

the compressor/heaters.

- PROTECTION: The PerformexTM Controller will provide the following protection:

1. Compressor high pressure protection (option)

2. Compressor low pressure protection

4. INDOOR (EVAPORAT OR) FAN: There is one indoor fan with single fan speed. When fan speed on LCD panel is HIGH, indoor fan

will always turns on. Indoor fan can be set off, when the compressor is cut off by setting the fan speed to AUTO on the LCD panel by pressing Fan button. By pressing the Fan button again the fan speed can resume to HIGH.

C to 300C (610F to 860F), both inclusive. Press

5. COOL MODE: Whenever the unit is started in cool mode (without Pump Down Solenoid-PDS), the compressors will be turned on

one by one depending on the load requirement of the unit.

6. HEAT MODE (HEATER MODEL): Whenever the unit is started in heat mode, the heaters shall be switched ON one by one to

meet the load requirement.

Page 17

7. LEAD/LAG OPERATION: Whenever a compressor needs to be on, the controller will turn on the compressor with

the shorter accumulated run time provided its 3 minutes minimum off time has lapsed. Otherwise the other compressor will on first. Similarly, the compressor with the longer accumulated run time will be the first one to be cut off. This is to load the compressors evenly over long run period. Balance loading is enabled when compressor #1 lead option is disabled.

8. AUTO MODE: In Auto mode, operating mode will be selected automatically between Heat and Cool mode, depend-

ing on the Room Temperature and Set Temperature.

9. ERROR CODE:

Error code is displayed on the LCD panel. When system on and error code is shown, the ON/OFF LED on the LCD panel will blink. When system off, error code is still display for thermistor error but the ON/OFF LED will be off.

E06 Compressor 1 high pressure trip (or contact open) E07 Compressor 2 high pressure trip (or contact open), (not applicable for single compressor units) E10 Compressor 1 low pressure trip E11 Compressor 2 low pressure trip, (not applicable for single compressor units)

CRANKCASE HEATER

The crankcase heater is provided to hold the compressor oil reservoir at higher temperature than the coldest part in the system.

• Power must be supplied to crankcase heater for a minimum of 12-hours prior to system start-up. If power is off for 6-hours or more,

crankcase heater must be energized for 12-hours before operating the system. Otherwise compressor damage may result.

PUMP DOWN CONTROL

If the unit is provided with pumpdown system, then a solenoid type valve is installed in the liquid line ahead of expansion valve to prevent flow of refrigerant into the evaporator during off cycle. The controller is wired to solenoid valve which energize in cooling and opening the valve. Whenever the thermostat temperature is satisfied, the solenoid will close followed compressor off after pumping the refrigerant from low side of the system until the low pressure switch open the control circuit.

MAINTENANCE INSTRUCTIONS

AIRFLOW ADJUSTMENT (Applicable for PT075 - PT360 only)

The airflow could be adjusted by adjusting pulleys of blower motor or belt tension with proper mounting and alignment of the pulleys:

• Refer to fan performance tables in the catalog for selecting applicable airflow, RPM and brake horse power at specified static

pressure.

• Select the appropriate drive as per motor and blower characteristic in the catalog.

• The set screw shall be loosened to make the pulley moving.

• Adjust pulley’s diameter, opening counter clockwise to reduce RPM and further reduce airflow, while closing clockwise increases

RPM and airflow.

• Tighten the set screw and then install the belts.

• Test the unit operating airflow for further adjustment.

CRANKCASE HEATER

• Periodic checking for proper operation or crankcase heater is highly recommended as follows:

a) Check continuity of the heater using multimeter device. b) Check grounding of the heater by Meggar device (to prevent electrical hazards). c) Observe whether the heater is warming down the compressor near the oil sump.

CLEANING OF COILS & FILTERS

• Turn off the power supply.

• Take out access panel of evaporator coil.

• Remove the filter from its access panel.

• Protect electrical components and motors from water washing.

• Clean the coil by flushing water by pressure washer followed by compressed air from supply to return direction.

• Filter shall be cleaned every six month, in some hygienic application it is recommended for replacement.

• Cleaning drain pan and trap is recommended once in a year to prevent bacteria growing under the coil.

BELT TENSION TESTING PROCEDURE INSTRUCTION (Applicable for PT075 - PT360 only)

To determine the lbs. force required to tension a drive, you simply do the following:

1. Measure the Belt span as shown.

2. Divide belt span by 64 to get belt deflection needed to check tension.

3. Set large "0" ring on span scale at required belt deflection. This scale is in 1/16" increments.

4. Set small "0" ring at zero on the "Force Scale" (plunger).

5. Place the larger end of the tension checker squarely on one belt at the center of the belt span. Apply force on the plunger until the bottom of the large "0" ring is even with the top of the next belt or with the bottom of a straight edge laid across the sheaves.

6. Read the force scale under the small "0" ring to determine force required to give the needed deflection.

7. Compare the force scale reading with the correct value for the belt style and cross section used, as given in table on next page. The force should be between the minimum and maximum values shown.

8. If there is too little deflection force, the belts should be tightened. If there is too much deflection force, the belts should be loosened.

Note: Tension new drives at the maximum deflection force recommended. Check the tension at least two times during the first day's operation as there normally will be a rapid decrease in belt tension until belts have run in. Check the tension periodically after the first day's operation and keep tension in recommended area. The correct operating tension for a V-belt drive is the lowest tension at which the belts will not slip under the peak load conditions. Shafts must be adequate for the tensions required.
