clearance height.
The exhaust troughs should be installed as soon as the machine is leveled so that the sheet metal
or PVC contractor can install the exhaust piping and blowers (see
Section 6 – Auxiliary Connections ).
4.7. EXHAUST TROUGH AND BLOWER
The exhaust troughs should be installed as soon as the machine is leveled so that the sheet metal
or PVC contractor can install the exhaust piping and blowers. If a trough ends up supporting the weight of
the exhaust pipe above it, then a brace should be fixed so that trough end and extend down to the floor
for support.
Based upon preliminary feedback information, the customer is provided with advice on how to install his
blowers, depending on proximity of location and climatic conditions. It is the
customer’s responsibility
to supply and install the blowers. If the exhaust is through the roof, the blowers can be mounted under
the roof, or outside on the roof
‐ top. In certain cases, blowers may be mounted outside a nearby wall.
The horizontal run of the exhaust should pitch downwards towards the blower to allow water to drain
outwards.
Prior to freezer shipment, the appropriate installation drawing for each blower mounting is forwarded
to the customer to pass on to his installation contractor who is normally responsible for mounting and
connecting the exhaust to the trough outlet and the blower inlet.
For more information on exhaust system installation, see Section 5.3 – Exhaust System Installation .
4.8. FINAL ADJUSTMENTS
All nuts and bolts should be checked to be sure they are tightened properly. They should be rechecked
after the first few days. The expansion and contraction caused by temperature changes can cause
threaded fasteners to work loose.
5. Auxiliary Connections
To ensure proper supply connections, take into account any restrictions as provided in Appendix B –
Reference Drawings when designing the supply connections. To allow for proper installation once the
freezer is in place, make sure the following is made available at the in ‐ plant freezer location:
•
provisions for electrical power supply and connection;
•
provisions for LN
2
supply and connection;
•
provisions for proper installation and connection of exhaust duct;
•
floor drains and corresponding floor pitch as required for drainage of cleaning water.
The liquid nitrogen piping and electrical conduits should be well protected against accidental damage.
To minimize liquid nitrogen consumption, avoid elbows where possible and ensure piping runs are as
short and direct as possible.
