2.0 GENERAL INFORMATION
2.1 RECEIVING,
INSPECTION AND
PACKAGING
As soon as the unit is received, it should be
inspected if there is any damage during transit.
Make a separate written request if there is any
damage on the carrier's delivery order. Also,
the unit should be inspected for any missing or
short shipped components. Standard items and
accessories that come with the unit are:
2.1.1 AIR-COOLED CONDENSING
UNITS (ACCS)
1.) Compressor(s) c/w rubber grommet.
2.) Condenser coil(s).
3.) Condenser fan(s)- Refer to physical
data for sizes and quantity.
4.) Condensers fan motor(s)- Refer to
physical data for horsepower and
quantity.
5.) Fan grille.
6.) High and Low pressure switch.
7.)
Reversing valve, check valve
suction accumulator and
compressor crankcase heater
(standard for heat pump only).
8.) Optional accessories (if any).
1. IEC-DOL (Direct On Line)
starter, wired
2. Low ambient fan cycling
(standard for Heat-Pump).
3. Hot gas bypass
4. Stop
valves
5. Mains
isolator
6. Hydrophilic condenser coil fins
(standard for Heat Pump)
7. Indicator
lights
8. Stainless steel bolts and nuts
2.1.2 EVAPORATOR BLOWER
UNITS (HEB-D/ VEB-D/ EB-D)
1.) Blower(s) wheel.
2.) Evaporator coil.
3.) Thermal expansion valve(s) and
distributor(s).
4.) Bearings and shaft.
5.) Optional accessories.
1. Double
wall
casing
2. Hot water heating coil
3. Electric heater coil
4. Thermostat, unit mounted for
cooling only
5. Thermostat, remotely mounted
for cooling only and heat pump
6. Discharge plenum and return
air grille
2.2 RIGGING AND
UNCRATING
Each unit has been tested, inspected and
properly packed or crated prior to delivery. It
is very important that precaution is taken in
handing the units by the installers, movers and
riggers. When lifting with slings, use spreader
bars across the top of the unit to prevent any
damage to the frame and panels. Rigging
should be done in a manner to avoid any
severe strain or stress on the unit which will
scratch the paint works and damage the panels
and framework. Avoid possible surface
damage by not removing the packaging
material until the unit is at or near the final
location and soon to be installed. Check the
weight of the unit before rigging. Place the
rigging cable such that the weight is evenly
distributed.
2.3 LIMITATIONS
1.) Avoid low return air temperature on
evaporator coil which might cause
condensate to freeze up the surface of the
evaporator coil.
2.) Avoid moisture carry over and excessive
noise, limit evaporator coil face velocity
to 3.05 m/s [600FPM].
3.) Unit must be operated on the correct
electrical supply as specified on unit
nameplate. Voltage limitation for
compressor(s) and fan motor must be
observed.
4.)
Avoid low return air temperature on the
condensing coil which might cause low
discharge pressure (heat pump unit is
equipped with fan cycling to maintain the
head pressure). Refer to Table 2.3.
