D. RECEIVING AND INSTALLING REMOTE CONDENSING
UNITS
NOTE
The remote condensing units may be sent prior to
delivery of the freezer.
The freezer requires one remote condensing unit
per cylinder.
Remote condensers for 60Hz units are shipped
from the factory charged with 20 lbs of refrigerant.
Remote condensers for 50Hz units are shipped
without refrigerant and require 20 lbs of refrigerant.
1. Upon arrival, check the entire remote condenser
units for any damage that may have occurred
during transit. With the method of packaging used,
the remote condensers should arrive in excellent
condition. The carrier is responsible for all damage
in transit, whether visible or concealed. Do not pay
the freight bill until the remote condenser units have
been checked for damage. Have the carrier note
any visible damage on the freight bill. If concealed
damage or a shortage is found later, advise the carrier
within 10 days and request inspection. The customer
must place a claim for damages and/or shortages
in shipment with the carrier. Stoelting cannot make
any claims against the carrier.
2. Remove cardboard covering off the condensing
units.
3. Place the condensing units in their predetermined
location, either on the roof or on the ground. A
crane or forklift is needed if the units are placed on
a roof. The condensing units weigh approximately
200 lbs. each.
4. Using ratchet with a 1/2” socket, remove the two lag
bolts that secure the condensing unit to the pallet.
5. Place the condensing units on 4” x 4” treated
wood or similar material so that the units are not
sitting directly on the ground or the roof. Secure
the condensing units to the 4” x 4” using lag bolts.
Adhere to all local, state, and federal codes governing
this type of installation. Some areas have specific
“hurricane-proof” requirements for roof installations.
Allow at least 3 feet of clearance on the air intake
and discharge sides of the condensers. Do not set
the condensers so that one is blowing air directly
into the other condensing unit. The ideal set up is to
have all the condensing units set in a row (Fig. 2-1).
6. Connect the refrigeration lines to the condensing
unit:
For condensing units without piercing unions
a. Braze the suction line and liquid line from the line
sets to the condensing unit. When brazing, wrap
the shut off valve with a cold wet rag and make
sure that the valve is fully open. If the valve is not
wrapped, damage may result. When installing the
suction line, angle it towards the condensing unit
so that oil can flow back towards the compressor.
b. Use good piping practices. Keep pipes as clean as
possible. Do not let any debris or copper shavings
get inside system otherwise the refrigeration
valves may not work properly.
For condensing units with piercing unions
a. Thread the line set fittings onto the condensing
unit by hand.
b. Tighten the fittings with a wrench until the
coupling bodies “bottom out”.
c. Use a torque wrench to tighten the fittings to
46±1 ft-lbs.
NOTE
The piercing unions are a one-time connection. Do
not loosen the fittings after installing or refrigeration
charge will be lost.
