Remote Condenser Installation
For proper operation of the Ice-O-Matic ice machine, the following installation guidelines must be followed. Failure to do
so may result in loss of production capacity, premature part failure, and may void all warranties.
Use the following
for planning the placement of the remote condenser relative to the ice machine.
Location Limits: Remote condenser location must not exceed ANY of the following:
●
Maximum rise from the ice machine to the remote condenser is 35 physical feet.
●
Maximum drop from the ice machine to the remote condenser is 15 physical feet.
●
Physical line set maximum length is 75 feet.
●
Calculated line set length maximum is 100 feet.
●
Ambient operating temperatures: -20°F (-28.9°C) to 120°F (48.9°C)
Calculation Formula
●
Drop = dd x 6.6 (dd = distance in feet)
●
Rise = rd x 1.7 (rd = distance in feet)
●
Horizontal Run = hd x 1 (hd = distance in feet)
●
Calculation: Drop(s) + Rise(s) + Horizontal Run = dd+rd+hd=Calculated Line Length
Configurations that do NOT meet these requirements must receive written authorization from
Ice-O-Matic. This includes multipass or rack system remote condensers.
Do NOT:
●
Route a line set that rises, then falls, then rises.
●
Route a line set that falls, then rises, then falls.
Remote Condenser Location:
Limited to a 25, 40, 45, 60 or a 75 foot length of precharged refrigerant tubing connecting the ice machine to the remote
condenser. The remote condenser must be above or level with the ice machine. Select the best available location,
protecting the remote condenser from extremes of dirt, dust and sun. Meet all applicable building codes. Usually the
services of a licensed electrician are required.
Roof Attachment:
1. Install and attach the remote condenser to the roof of the building, using the methods and practices of construction that
conform to the local building codes, including having a roofing contractor secure the remote condenser to the roof.
2. Have an electrician connect the remote condenser fan motor wires to the ice machine, using the junction box at the
back of the ice machine.
Precharged Line Set Routing
CAUTION: Do not connect the precharged tubing until all routing and forming of the tubing is complete. See the
coupling instructions for connecting information.
1. Each set of precharged tubing refrigerant lines consists of a 3/8 diameter liquid line and a 1/2 inch diameter discharge
line. Both ends of each line have quick connect couplings, one end has a Schrader valve connection which goes to the
condenser.
Note:
The openings in the building ceiling or wall, listed in the next step, are the minimum sizes recommended for
passing the refrigerant lines through.
2. Have the roofing contractor cut a minimum hole for the refrigerant lines of 2.50 inch. Check local codes, a separate
hole may be required for the electrical power to the condenser.
CAUTION: DO NOT KINK OR CRIMP REFRIGERANT TUBING WHEN INSTALLING IT.
3. Route the refrigerant lines through the roof opening. Follow straight line routing whenever possible. Any excess tubing
MUST remain within the building.
4. Spiral the excess length of precharged tubing inside the building. Use a horizontal spiral to avoid any traps in the lines.
5. Have the roofing contractor seal the holes in the roof per local codes.
CAUTION: The couplings on the sets of precharged lines are self sealing when installed properly. Carefully
follow the instructions in the VRC manual.
