We encourage you to read the
entire installation manual before attempting to
install a Rite-Temp water chiller. If you encounter
any problems or have any questions concerning the
installation process, please feel free to contact
us. Our staff of technicians are on hand to assist
you during the hours of 8:00 a.m. to 4:30 pm (Central
Time), Monday through Friday. Our toll free support
number is 800-462-3120. We may also be reached
at Chillers@RiteTemp.com
1.
Immediately upon receiving shipment, equipment
should be inspected for evidence of any damage
received in transit. If shipping damage has
occurred, a claim should be made with the transportation
company, and the local Rite-Temp representative
should be advised of nature of damage.
2. Equipment should be inspected for compliance
with original order acknowledgement (equipment
model numbers, voltages, etc.).
1. Equipment should be lifted in a near level
condition to prevent undue stress on structural
members.
1. Equipment should be mounted on a smooth, hard,
level surface.
2. Mounting surface should be rigid, and provisions
should be made to prevent noise transmission
(structural) to surrounding areas.
3. Air cooled equipment should not be installed
under low structural overhangs which can cause
condenser air re-circulation or restriction.
4. Adequate Area (approx. 1 unit width) must
be provided around equipment for unrestricted
air flow and service. Two units side by side
should have a minimum of 1.5 unit width between
them.
5. Care should be taken to prevent air from other
sources from entering condenser if this air is
at an elevated temperature.
6. Indoor design equipment must be installed
in a protected enclosure.
1. All piping must be in accordance with applicable
local and state codes.
2. Refrigerant piping (split systems) should
be designed and installed in accordance with
recommended practices as outlined in ARI or ASHRE
piping guide. (Engineering Guide #l for air conditioning
systems.)
3. Water piping (Chillers) should be designed
and installed to meet application requirements.
Provisions must be made to prevent freezing if
design ambient temperatures dictate.
4. Compressor shipping hold down bolts (spring
mounted compressors) should be loosened until
compressor swings free on its isolators before
piping is made-up. Line isolators or loops must
be used with spring mounted compressors.
5. When piping is completed, a thorough leak
test should be performed before evacuation start-up.
Do not exceed 150 psig test pressure on low side
of system.
1. All local and state codes must be strictly
adhered to and good electrical practices should
be followed to achieve the best installation
possible.
2.Power wiring to equipment must be adequately
sized for minimum ampacity as shown on unit nameplate.
A disconnect connect should be located adjacent
to unit for both safety and servicing purposes.
3. Equipment wiring diagram should be examined
and thoroughly understood before field wiring
connections are made.
4. Power supply should be checked to be certain
that sup ply voltage agrees with equipment nameplate.
Serious damage to compressors and motors can
occur if improper voltage is applied.
5. When wiring is completed, fan motors should
be checked for proper rotation. All fan motors
of multiple fan equipment have been factory wired
to operate with same rotation. If rotation is
found to be incorrect, reverse two or thee leads
on main incoming power.
1. With refrigerant piping completed and leak
tested, equipment is ready to evacuate. Do
not use compressor to evacuate system. A quality
vacuum pump capable of 350 micron vacuum is
necessary for adequate and dependable system
vacuum. Moisture in a refrigeration system
can cause corrosion, expansion valve freeze-up
and oil sludge.
2. Attach vacuum pump to both high and low side
of system through compressor service valves and
evacuate to 350 microns (all service valves,
hand valves, and solenoids must be open during
evacuation). It is suggested that vacuum pump
be run for a period of time after vacuum has
been reached.
1. This will involve checking and adjusting of
all safety and operating controls (pressure
and temperature controls have been set at the
factory; however, it is still desirable to
confirm that settings are correct and controls
function properly). Do not attempt to function
safety controls without some means of stopping
compressor in event of extreme high or low
pressure conditions that could damage the equipment.
If controls fail to function at set point,
determine cause and correct. Jumpering any
safety control other than for testing purposes
is dangerous to personnel and equipment, and
nullifies equipment warranty.
2. The bottom opening is the pump outlet to your
process. The middle opening is the return inlet
water coming back to the reservoir tank. Fit
a union and a tee in the return line. Bring the
make-up water line to the tee. This is used to
fill the chiller and system.
3. With the chiller switch OFF, turn on the MAIN
POWER to the chiller. Even though the chiller
switch is off, the main power will activate the
compressor crankcase heater to warm up the oil
and burn off any freon that has migrated into
the crankcase (this feature is standard in ALL
compressors). Allow the compressor(s) to warm
overnight, or at least six hours.
Allow the compressor(s) to warm overnight, or
at least six hours. This is a one time procedure
for start-up. However, if the main power is
off for over 24 hours, (four hours if outside
in cold weather), then the warm-up procedure
should be repeated. To fill chiller, open the
city water and fill at a SLOW RATE. When water
comes out of the 1/2" top vent opening
it means the reservoir tank is full. SHUT WATER
OFF. Open all valves to process and start chiller
for about 15 seconds to fill lines and equipment.
STOP CHILLER. Open city water again at a SLOW
RATE till water again comes out of the vent
pipe. SHUT THE WATER OFF. The system is full
and ready for use.
1. Equipment which will not be required to operate
for a period of time should be secured by storing
refrigerant charge in the receiver or condenser.
On units with coolers or water cooled condensers.
special precautions must be taken to completely
drain the vessels to prevent freezing if ambient
should be below 32°F.
2. Inspect system for possible worn or faulty
components and repair if required.
1. Thorough leak test should be performed.
2. Coil(s) should be checked for dirt accumulation
or obstruction and cleaning if necessary.
3. Refill water system and purge all air from
system.
4. Energize crankcase heaters and allow a minimum
of 12 hours operation before compressor restart.
5. install gauges, start system and check for
correct refrigerant charge, and proper system
operation and balance.
I . The system should be checked periodically.
Use only the services of a qualified refrigeration
mechanic for inspection and maintenance checks
or service operations.
2. Water Treatment (Chillers and Water Cooled
Condensing Units) - The water should be tested
by a local testing agency and their recommendations
adhered to.
3. Air Cooled Condenser ? The inlet side of the
condenser coil must be kept clean through a regular
prevention maintenance program.
4.Periodically checks all electrical connections
for possible loose or corroded terminals. Repair
as necessary.
A. Temperature Control Setting too low - Readjust
to proper setting. VCheck catalog or submittal
data.
B. Cooler flow incorrect - Balance flow to catalog
or submittal requirements
C. Low refrigerant charge - Recharge to correct
operating level - clear sight glass.
D. Restricted liquid line - Check valves and
dryer.
E. Thermal expansion valve adjustment - Adjust
superheat to approximately 10° - 12° F.
