INSTALLATION, START UP AND SERVICE INSTRUCTIONS
FOR CONDENSING UNITS
COMPRESSOR LUBRICANT: PVE(polyvinylether) or synoil are typically used as the
lubricant for R-410A.
CHARGING SYSTEM WITH R-410A: It is essential when charging the system with
R-410A that the system be liquid charged by removing only liquid from the cylinder.
Never charge the system with vapour from a cylinder. Vapor charging R-410A may
result in the wrong refrigerant composition and could damage the system. Therefore
the cylinder must be equipped with a dip tube to facilitate liquid removal with the
cylinder in the upright position.
LEAK DETECTION: Service personnel have used leak detection equipment for
years when servicing equipment. Leak detectors exist not only for pinpointing
specific leaks, but also for monitoring an entire room on a continual basis for the
absence of oxygen or presence of refrigerants. There are several reasons for leak
pinpointing or area monitoring, including: conservation of refrigerants, protection of
valuable equipment, reduction of fugitive emissions, and protection of employees.
Prior to the purchase of detector or monitor, make sure you consider your
requirements or criteria for the monitor such as sensitivity, detection limits, and
selectivity. Another simple method used to find leaks is to coat the suspect area with
a soapy water solution and look for soap bubbles.
CHECK SYSTEM OPERATION: Start the system and let conditions stabilize. If the
system is under charged, add additional R-410A in increments of 5 percent by
weight. Continue until desired conditions, 2700 kpa for high pressure and 700 kpa
for low pressure, are achieved.
REFRIGERANT CHARGING: If recharging is necessary, weight in the total charge
as indicated in the charging table. Remove any refrigerant remaining in the system
before recharging. If the system has lost the complete charge, evacuate and
recharge by weight.

OUTDOOR UNIT INSTALLATION GUIDE
STEP 1 - COMPLETE PRE-INSTALLATION CHECKS
UNPACK UNIT - Move unit to its final location. Remove the carton from unit being
careful not to damage the service valves and grilles.
INSPECT SHIPMENT - File a claim with the shipping company if the shipment is
damaged or incomplete.
CONSIDER SYSTEM REQUIREMENTS - Consult the local building and national
electrical codes for any special installation requirements.
Allow sufficient space for air flow clearance, wiring, refrigerant piping, and servicing
the unit. See fig. 1.Locate the unit so that the condenser's air flow is unrestricted on
both sides. Refer to fig. 2.
The unit may be mounted on a level pad directly on its base legs or mounted
on raised pads at the support points.
STEP 2 - RIG AND MOUNT UNIT
MOUNTING ON GROUND - Mount on a solid, level, concrete pad. Position unit so
water or ice from the roof cannot drop directly onto the unit. If local codes require the
unit be fastened to the pad, tie down bolts should be used and fastened through the
slots provided in the unit's mounting feet.
MOUNTING ON ROOF - Mount on a level platform or frame. See fig. 2.
RIGGING
Be sure unit panels are securely in place prior to rigging.
Keep unit upright. Lift unit using slings. Use cardboard or padding under sling, and
spreader bars to prevent any sling damage to the unit. Install the unit so that the coil
does not face into prevailing winds. If this cannot be done, and constant winds above
22 kM/HR are expected, use a wind baffle.

STEP 3 - COMPLETE REFRIGERANT PIPING CONNECTIONS
The condensing units may be connected to the evaporator section using field
supplied tubing of the correct refrigerant grade, size and condition. Do not use less
than 3m of interconnecting tubing and do not bury more than one metre of line set
underground.
If more than the recommended length is buried, the refrigerant may migrate to the
cooler buried section during extended periods of unit shutdown. This causes
refrigerant slugging and possible compressor damage at start-up.
When more than 15 m of inter-connecting tubing and /or more than 10 m vertical lift
is used, consider the amount of liquid lift and compressor oil return or contact your
local distributor.
If either the refrigerant tubing or indoor coil is exposed to atmospheric conditions for
longer than 1 minute, it must be evacuated to 1,000 microns to eliminate
contamination and moisture in the system. Run the refrigerant tubes as directly as
possible, avoiding unnecessary turns and bends. Suspend the refrigerant tubes so
they do not damage
Insulation on the vapour tube and do not transmit vibration to the structure. Also,
when passing the refrigerant tubes through the wall, seal the opening so vibration is
not transmitted to the structure. Leave some slack in the refrigerant tubes between
the structure and unit to absorb vibration. Refer to evaporator installation instructions
for additional information.
MAKING PIPING FLARE CONNECTIONS
Both the suction and liquid lines of the units are equipped with flare connections
which are closed off in the factory and ready for connection. Use refrigerant grade
tubing. Assemble flared joint by aligning the tubing with the machined surface of the
fitting. Turn the nut anti-clockwise and then clockwise until it is fully tightened. Leak
test the joint to ensure it is leak free.
STEP 4 - COMPLETE ELECTRICAL CONNECTIONS
POWER WIRING - The unit is factory wired for the voltage shown on the name plate.
Provide an adequate fused disconnect switch within sight of the unit, readily
accessible, but out of reach of children. Provision for locking the switch open (off) is
advisable to prevent power from being turned on while unit is being serviced.
Disconnect switch, fuses, and field wiring must comply with local code requirements.
Use only copper wire between the disconnect switch and unit. Route power wires
through the opening in unit’s side panel and connect to the unit control box as shown
on the unit’s label wiring diagram. Unit must be grounded.
CONTROL CIRCUIT WIRING - The control voltage ares 230VAC. See unit label
wiring diagram.
Route the control wires through the opening in the unit’s side panel to connect
into the unit control box.
